New Milestones for Fisheries Transparency in Indonesia and Peru

Global Fishing Watch and SkyTruth team members at the Our Oceans conference in Bali, Indonesia.

Until recently public tracking of fishing activity has been almost entirely dependent on AIS (Automatic Identification System) data, an open system for vessel tracking and collision avoidance. It’s exciting to see this changing with the success of Global Fishing Watch’s Transparency Program. This program began when Indonesia’s fisheries minister Susi Pudjiastuti took the unprecedented step of sharing the country’s Vessel Monitoring System (VMS) tracking data publicly on Global Fishing Watch. VMS had traditionally been a closed monitoring system accessed only by government authorities. Public VMS made thousands of smaller Indonesian fishing vessels trackable in an region with little AIS coverage and established a new policy of total transparency to reinforce Minister Susi’s overhaul of a fisheries sector previously plagued by illegal fishing and labor abuses.

The Our Oceans conference last week in Bali, Indonesia was a chance to showcase the great work of our Indonesian team, recently including analysis of VIIRS (Visible Infrared Imaging Radiometer Suite) nighttime satellite imagery for detecting possible illegal activity in Indonesian waters and developing a process for validation of fishing effort predicted from VMS tracks along with Indonesian researchers. It’s also exciting to see that Indonesia has started a trend in choosing transparency in fisheries monitoring. Peruvian VMS tracking data now appears on the Global Fishing Watch map dramatically increasing our coverage of fishing in the eastern Pacific.

Here in Lima it has been great to see the Peru program take shape beginning with the commitment last year to publicly share VMS with Global Fishing Watch. Since then we have held workshops and training sessions with Peru’s Marine Research Institute and vessel monitoring authorities. I also recently had a chance to attend Peru’s biannual marine sciences conference (CONCIMAR) where along with Oceana Peru we put on a workshop for Peruvian students and announced the release of Peruvian data on the Global Fishing Watch map.

Both here in Peru and in Indonesia we are excited to see the beginning of a new era of transparency in monitoring and managing fishing resources. New tools and data sources developed by Global Fishing Watch and SkyTruth are being made available to local students, researchers, and government regulators. We are particularly pleased to see so much local interest from the countries that have chosen to share their tracking data publicly. And this is just the beginning. Global Fishing Watch has big plans for supporting fisheries transparency in the future as we aim to work with 20 countries in making their fishing fleets publicly trackable in the next five years.

Tracking the Chinese Squid Fleet in the South Pacific – Part 1: Voyage to the Galapagos

When monitoring vessel activity on the vast scale of the world’s oceans at SkyTruth we know we’re almost always dealing with incomplete information. For example, only some vessels transmit their locations at sea via the Automatic Identification System (AIS), while others may only come up in a particular government’s private Vessel Monitoring System (VMS) or we may just see them as blips on a radar screen. So I was excited to hear that I was invited to accompany a vessel actually going out to investigate one of the fleets we have been monitoring with AIS and night imagery. The ship I would board is the M/V Brigitte Bardot, a 35 meter former racing vessel now run by Sea Shepherd, an international non-profit dedicated to taking direct action for marine conservation. In 2016 Sea Shepherd was able to track down some unusual vessel activity that we spotted in the Indian Ocean with spectacular results.  This time we would be tracking a much larger fleet fishing for squid in international waters 700 miles west of the Galapagos.

Squid doesn’t come to mind when you consider the targets of the world’s largest fishing fleets. However, over the past few years the magnitude and global scale of squid fishing fleets have become apparent. Due to powerful fishing lights used to attract squid to the surface these fleets appear on NASA’s night imagery like cities floating hundreds of miles offshore. Recent analysis of vessel movements shows that they are interconnected with hundreds of predominantly Chinese flagged vessels moving between fleets along the Peruvian Exclusive Economic Zone (EEZ) boundary, the South Atlantic, the northwest Pacific, and even the northern Arabian Sea.

We’ve been monitoring the squid fleet fishing at the Peruvian EEZ boundary for some time. We noticed a handful of vessels in the fleet broadcasting false AIS locations. Then in 2017, we were puzzled when the entire fleet suddenly picked up and relocated 3,000 miles to the northwest of the EEZ boundary, to a remote area west of the Galapagos. So as I boarded Sea Shepherd’s Brigitte Bardot, I was really curious to find out the real size of the fleet and why so many vessels appeared concentrated at this remote location.

On September 12th, we set off from Panama City with some of us suffering from the rough seas as we steamed southwest towards the Galapagos. I was able to meet the very enthusiastic crew on the Brigitte Bardot, including a professional photographer, a drone pilot, and a fantastic vegan cook. We were also fortunate to be accompanied by Eloy Aroni, a Peruvian researcher who was just completing his thesis on tracking the squid fleet with nighttime satellite imagery from NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS). After three days, we crossed into the Southern Hemisphere with the ship’s engineer taking a celebratory swim across the Equator. Later that afternoon, we sighted the desolate coast of San Cristobal Island, and after rounding the sheer rock cliffs of Sleeping Lion Rock, we entered the island’s main port.

We were held up in San Cristobal for a few days dealing with customs and inspections. This delay gave me a chance a to see bit of the island’s interior and review the latest information I had on the fleet we were tracking. Our data came from three sources, vessel AIS broadcasts, VIIRS night imagery, and interestingly two synthetic aperture radar (SAR) images of the fleet provided by Kongsberg Satellite Services (KSAT) as we were heading out. While SAR imagery is acquired routinely by the European Space Agency’s Sentinel-1 system over land and coastal areas it’s unusual to have imagery over the open ocean. So we were lucky to have access to a few shots of the fleet provided by KSAT from Canada’s Radarsat-2 satellite. This allowed us to make a comparison to our usual tracking sources for the fleet, AIS and VIIRS night imagery.

Those vessel detections outlined in green were found by KSAT to align closely with AIS broadcasts. Detections outlined in red could not be identified confidently with AIS. The inset on the lower right shows at larger scale the detection of the squid jigger Hsiang Man Ching. The large number of unidentified (red) detections was likely due to limited satellite AIS reception and does not necessarily indicate that the vessels were not broadcasting AIS.

AIS gives vessel locations and (usually) vessel identities. VIIRS gives us an approximate count of the number of vessels with their fishing lights lit up on a particular night. However, with no law requiring AIS use and the fact that VIIRS imagery is relatively low resolution (and still untested against this particular fleet), we suspected that these data sources might be giving us an incomplete picture of the total fleet activity. For these reasons, it was useful to make a comparison with the two SAR images since they should pick up every vessel present in the area, provided they are metal and above a certain size. Ultimately, comparison between the SAR vessel detections and total AIS broadcasts showed that despite a number of SAR vessel detections that could not be identified with AIS (outlined in red in the figure from KSAT above) the total number vessels detected by both systems was approximately the same, indicating high AIS use for the fleet, but also with a few clusters of radar detected vessels not associated with AIS.

After refueling on Baltra, a barren island with a former US military base, and installing a new satellite communications system, we set off on September 19th. In the evening we rounded the north cape of Santa Isabela Island and headed west into a vast stretch of the open Pacific. Ahead of us the nearest land was 3,000 nautical miles away in the Marquesas Islands of Polynesia. We would be venturing across some of the most remote surface of our planet on a voyage that would launch Operation Mamacocha, Sea Shepherd’s newest campaign fittingly named after the Incan sea goddess.

A look back at 20 years of oil and gas permitting in Wyoming

A shift in priorities of the EPA under the current administration has raised awareness of an increase in oil and gas permitting across the USA. However, the increase began before the current administration. Although the federal government controls most regulations and laws that affect permitting, other factors such as global oil and gas prices, advances in drilling and production technology, and state governments’ willingness to accommodate investors have an effect on permitting and investment by energy companies. It should be pointed out that permitting does not necessarily indicate drilling as companies can request permits but then hold on to the permits until either eventually drilling, requesting a new permit, or selling the permit to another company. This can tie up land for decades and is covered in more detail by The Wilderness Society’s report: “Land Hoarders: How Stockpiling Leases is Costing Taxpayers”.

Wyoming has an economy that is built on coal and oil, but in the 80s and early 90s it was suffering from an oil glut that caused prices to drop. As prices began to recover throughout the 1990s and 2000s and eventually boom (Fig.1), some companies sought to diversify into natural gas (read more in James Hamilton’s paper “Causes and Consequences of the Oil Shock of 2007-08). Many began to drill for gas in the coal fields of Wyoming, and to apply the relatively new technology of hydraulic fracturing (“fracking”) to extract natural gas from previously uneconomic, low-permeability sandstone and shale reservoirs found throughout the Rocky Mountain West.

Oil and gas prices since 1985.

Figure 1. Oil and gas prices since 1985.

The oil and gas boom ended abruptly in 2008 when the effect of the global financial crisis reached the oil and gas markets and prices plummeted.

To better understand the effect these events had on Wyoming, I analyzed permits for new oil and gas wells, issued by the state over the past 20 years. This data is freely available from the Wyoming Oil and Gas Conservation Commision website: http://wogcc.wyo.gov/. First, I should point out that this data has inconsistencies and holes, due to apparent data entry errors like missing or incorrect dates, missing latitude or longitude, typos, etc. Unfortunately, this meant nearly 24% of the total permits had to be left out of my analysis. Some errors still remain, as seen in this map of permit applications received by the state (Fig. 2). Each county is colored differently and there appear to be some permits which either have the wrong county listed or incorrect map coordinates.

Distribution of oil and gas drilling permit applications, color coded by county.

Figure 2. Distribution of oil and gas drilling permit applications, color coded by county.

What immediately stands out is the relatively densely-packed permits in Campbell county, in the north-east of the state. When I looked closer at this county over time, I saw that most of the permit applications were submitted during the beginning of the boom of 1998-2008. This is quickly followed by a sharp drop around 2000, the time hydraulic fracking made drilling in other parts of the state (and country) more profitable. The original method of coal bed methane drilling was considered uneconomical compared to this new fracking method. At that time, I saw a rise in permit applications across other counties (Fig. 3), but far more subdued than the earlier rush, possibly because fracking made deposits across the country viable and so the increase was more widespread across and outside Wyoming. This is just a theory though, these could easily be due to business strategies of companies “capturing” land before their competitors.

Applications for oil and gas drilling permits received over time by county.

Figure 3. Applications for oil and gas drilling permits received over time by county.

The rate of permit applications slows for all counties as the boom ended around 2008 with a short-lived rise leading up to 2016. The boom and bust periods can be seen more clearly when I looked at the overall quantity of permit applications across Wyoming (Fig. 4).

Total number of oil and gas drilling permits applied for in Wyoming.

Figure 4. Total number of oil and gas drilling permits applied for in Wyoming.

The initial rush of the boom was followed by a dip and second climb as fracking technology took off. This is followed by the bust of 2008. There is a slight rise again around 2016, but it drops off by 2017. The effect of this activity is closely reflected in unemployment figures for the state (Fig. 5). Considering that I am looking at permitting however, and not drilling, this correlation should be seen as a reflection of oil and gas companies’ business activities in a holistic sense.

Unemployment rate for Wyoming over the past 20 years.

Figure 5. Unemployment rate for Wyoming over the past 20 years.

Initially, there’s an overall steady decline in unemployment as the boom sweeps up employees but this rockets up once the bust comes along. Interestingly, between 2012 and 2016, there is a steady rise in permit applications which is reflected by the steady drop in unemployment but this is interrupted by a bump in unemployment around 2016. The restoring of the unemployment level after 2016 is not reflected in the drop in permit applications, however. Those appear to drop off.

Although there are booms and busts, the overall number of well permits is constantly increasing (by simple fact of the number of new permits applied for always outweighing the number of permits expiring). The animated image below (Img. 1) shows the growth of oil and gas permit applications as companies move across the state.

Image 1. Permits applied for over the past 20 years.

Image 1. Permits applied for over the past 20 years. (Click to see time-series)

Graphs and maps give us a good idea of the trends but sometimes it is even more helpful to see the physical reality of these numbers.  This is an area in the most heavily permitted county, Campbell (Img. 2).

Image 2. Comparison of an area of Campbell county from July 1999 to July 2018.

As well as the dramatic increase in well pads (i.e., drilling sites), these images show the addition of access roads threading across the landscape.

What this data doesn’t show is the large amount of orphaned wells that were left behind after the price of oil and natural gas dropped in 2008. This has left a legacy of about 3600 abandoned wells (scroll to bottom for total number of orphaned wells currently tracked by Wyoming Oil and Gas Conservation Commision). Often the state, and therefore, the taxpayers, are left to handle this burden because the responsible companies are either unknown, unable to cover the cleanup costs, or have declared bankruptcy and disappeared. Understandably, the state would prefer to see the wells operate once more rather than paying considerable amounts of money to seal them up and restore the land. But these aging, unsecured wells pose a threat to the environment and to public health.  

Many of the coalbed methane wells built at the beginning of the boom were approved with permission to dump untreated “flowback water” on the surface. The companies convinced the state that this  fluid, coming straight from the coal seams targeted by the drilling, would be beneficial for the parched land even though most of the untreated fluid was highly saline. Also, the effect of flooding the land with large volumes of water was extremely unnatural to the existing ecosystem. Many areas that were normally good for grazing became unusable because they were flooded with this salty water. Land that was adapted to little rainfall and snowmelt was suddenly exposed to a constant flow of brine. The companies pushed the idea of plentiful of water for agriculture and wildlife to drink while downplaying the issue of the quality of the water. The state also towed this line while court battles challenging the “beneficial use” permits, led by landowners and conservation groups, were upheld in court. Eventually, they implemented a water-to-gas ratio cap on surface discharges since many of the wells were producing plenty of salty water but little or even no gas at all.

One other trend that I discovered while scrutinizing the permit database was the time it took to process these permits (Fig. 6 & 7). Plotting permit approval times at first appears to show a distribution that follows the general trends that I’ve seen so far, tracking the boom and bust periods. For comparison, I plotted these for both the year of permit application (Fig. 6) and year of approval (Fig. 7).

Figure 6. Permit approval time arranged by year of application.

Figure 6. Permit approval time arranged by year of application.

 

Figure 7. Permit approval time arranged by year of approval.

Figure 7. Permit approval time arranged by year of approval.

The red lines track the annual average wait time and give a clearer picture of the trend. The spread of wait times fluctuate far more than the actual average wait time. Although the average does not appear to fluctuate much, the scale is a little deceptive as the average wait time extends from 15 days in 1998 to 40 days in the year 2000. The average wait time appears to initially rise with the start of each drilling boom but even out fairly quickly. This changes later when the average wait time climbs sharply around 2013. By 2017, the average wait time has increased considerably to 130 days.

These trends offer insight into the recent history of oil and gas permitting activity in Wyoming. It should be noted that although there was a lot of ‘noise’ in the data that I had to correct or discard, the remaining data helps give me a clearer sense of how oil and gas development is driving change on Wyoming’s landscape. My analysis has been based purely on the history of permitting in Wyoming, not actual drilling. For an analysis on drilling, please look at the Fracktracker Alliance’s page on oil and gas activity in Wyoming. I hope you’ve enjoyed this breakdown of permit data for Wyoming. I hope to take a similar look at other states’ drilling permits, so stay tuned!

The SkyTruther path: an intern’s excursion to understanding offshore oil (part I)

Practice does not guarantee perfection but it is a diligent educator. During my first week of orientation at SkyTruth, the other interns and I filtered through Sentinel 1 radar satellite imagery on the European Space Agency’s (ESA) online portal, compressed large .tiff image files using the command-line, and constructed final, publishable visuals in QGIS – a free, open source geographic information system (GIS), enabling users to create, view, edit, and analyze geospatial data. Essentially, we learned the fundamentals of finding, processing, and analyzing imagery.

Subsequent to grasping the basics, I worked on catching my first ocean offender by clicking through images, zooming in and out of rasters, and adjusting min and max values. Eventually, I spotted several shadowy slithers. Possible identification: oil leak.

Oil slicks off the coast of China.

The first image I discovered at SkyTruth.

Before hopscotching to conclusions, I checked in with mentor, Dr. Ry Covington (Doctorate of Philosophy; he’s not the medical type but he knows a thing about bodies – bodies of water, that is). Without hesitation, Ry confirmed my sighting as plausible. Three likely slicks from three unidentified sources. Mission success, phase two initiated: annotate.

When annotating an image, there are certain guidelines to follow. Most of the metadata – basic information needed to read a visual such as image credit/source, author, scale-bar, and date – is there. However, I did not include any boxed nouns or pointy things denoting the white zit-like points, or running, dark mascara streaks. Reflecting, I should have marked up this version more; I should have labeled the several pimples as unidentified sources, and measured the length of the eyelash-lacquer lines, ticketing them as slicks. Instead, I let the caption clamor over the image.

My first caption went something like this: “This image displays three leaks from several unidentified sources, off the coast of Guangzhou Province, China (near Hong Kong).”

That was all I got. New to the practice in general and unfamiliar with that latitude, I didn’t have much to say. So to boost productivity, I harvested a separate, bluer pair of eyes. My advisor with three first names, Christian James Thomas, looked over my caption. He was particularly picky with diction. One word, to be precise: leaks. Backspacing five times, Christian typed ‘slick’. Slick? Like ‘smooth’ or ‘glossy’? Or maybe like Eric Slick, the drummer of my favorite band, Dr. Dog? I wish, but certainly not.

‘Slick’ has various definitions, but to the SkyTruth team, slick typically describes flat water. Smooth surfaces on satellite radar imagery could signify oil, algae, lack of wind, or the like. What we are interested in is the accidental or purposeful release of oil or oily waste that may be a result of drilling, disposal, or disaster. Leak or spill is too specific, too assuming. I learned why this was after confusing slicks with a number of other ocean junk. When examining satellite evidence, slicks are often muddled by air and ocean current due to lag time between spill and image capture – this phenomenon also contributes to why some slicks exist without suspect in sight. Other times, slicks can be confused with false positives from weather events, natural disasters, coastal features, natural seeps, and other anomalies.

Bilge dumps off the coast of China.

This figure displays two likely slicks from intersecting bilge dumps off the coast of China. Due to their kinky shapes, these slicks are likely several days old; this image also shows the influence of time and natural forces on slick appearance.

Although I discovered how to be more transparent with terminology and make better imagery-based speculations, I did not know enough about slicks themselves. Oil naturally exists in the earth, and we harvest it to power our consumptive, energetic lifestyles. Sometimes, the oil itself leaks. In other other cases, wastewater produced during offshore drilling processes is released by us. This produced water is known as brine. Brine contains inorganic substances, toxic matter, and variably sized oil particles that must be properly disposed of or treated before release; it can be treated on platform and discharged into open water, transported to an offsite facility treatment or disposal facility, or put into beneficial reuse – for irrigation, recycled flowback fluid for other drilling operations, or as a substance for ice control (“Produced Water 101”, 2017).

Unlike shoplifting or arson, oil slicks are not always a result of unlawfulness. Some slicks are consequences of legal dumping – legality depending on individual cases in regard to international and country approvals. Accidental spills and leaks also occur and must be cleaned up. However, not all slicks are legally permitted or accidental and concern arises when oil slicks appear without record. Bilge dumping is one indicator of purposeful, often illegal, offshore pollution. To relieve ship weight and space, ships release oily waste from their engine and fuel systems, flushing residual material out of their cargo holds. This is highly illegal, as noted by a case in 2016, when Caribbean Princess, a luxury cruise ship under Princess Cruises, was fined $40 million for illegally discharging thousands of gallons of bilge. Senior intern, Daniel Nicholls, spotted a similar incident with another Princess Cruises ship in late January, indicating an ongoing dilemma.

A bilge dump from the Sapphire Princess.

Nicholls’s annotated Sentinel 1 radar satellite image of possible bilge dumping by Caribbean Princess-owned cruise ship, Sapphire Princess, as it heads towards Kuala Lumpur, Malaysia. Check out the full post here.

Now, I understand slicks not just as mascara tears or eyeliner blunders across a wrinkled ocean display; but as oily remnants with purpose and disposition. This comprehension allows me to more appropriately identify and interpret oil slicks in marine environments. As valuable as this was process and realization was, I registered that the beluga colored specks, aka the potential sources of the slicks, were still unidentified. Probably boats….

Who’s to blame? The murky dilemma of oil spill accountability

As global energy consumption continues to grow, Trinidad and Tobago — a small, Caribbean nation rich in oil and gas resources — has become one of the top exporters of liquified natural gas (LNG) in the world.  But the benefits to the economy of Trinidad and Tobago have come with a cost: chronic leaks and spills from aging oil and gas infrastructure on and offshore.

In early July, an abandoned oil well off of the west coast of Trinidad ruptured, sending dangerous hydrocarbons spewing into the ocean.  Trinidad and Tobago’s state-owned oil company Petrotrin stepped in to help address the rupture, but six days after the orphaned well erupted, the Ministry of Energy was still trying to determine which private company was responsible.

Insufficient documentation and incomplete record-keeping makes response efforts more difficult.  Gary Aboud, Corporate Secretary of Trinidad and Tobago’s Fishermen and Friends of the Sea (FFOS), summed up the the deeper issue in Trinidad concisely: Who is the responsible party? Nothing has been done all week…There are literally hundreds of decades-old, capped, orphaned or abandoned wells which may not have been properly decommissioned, and are corroding.”

Better documentation about ownership and better geospatial data showing oil and gas fields, pipelines, and abandoned wells would be a step in the right direction.  Some of this information is available but, as the map above shows, much of it is in a form that is very difficult to use. This energy map is pretty ‘busy’ — the various oil fields, gas fields, and pipelines depicted together make it difficult to use, especially in a crisis scenario like responding to an oil spill.

Officials need a comprehensive geospatial data set — filled with attributes like ownership or responsible party — that they can easily examine, especially during crises like this one.  One of my tasks as an intern at SkyTruth has been to pick apart the existing information (including the map above) and provide it as a robust geospatial data set that’s easy for the public to use.

A map of Trinidad and Tobago's gas fields and gas pipelines.

I’ve digitized all of the oil and gas fields, pipelines, and existing platforms around Trinidad and Tobago, and I’m constantly adding in new fields and data that I’m collecting about these features.

I’m using these new data sets — combined with Sentinel 1 radar satellite imagery — to help monitor oil leaks and spills around Trinidad and Tobago like the one described above.  Having better geospatial data will improve not only how companies handle clean-ups, but will also provide local fisherfolk with more insight into leaks and spills from oil infrastructure as they happen.

Global Fishing Watch Provides Training to Peru’s Vessel Surveillance Group

[Originally posted on the Global Fishing Watch blog, Aug. 15, 2018.]

We were very pleased to complete a three day training session this month in Lima with the Peruvian Ministry of Production’s vessel surveillance division. It was an opportunity for us to share the latest developments on the Global Fishing Watch mapping platform and to get expert feedback from professionals in Peru’s fisheries sector.

Since Peru’s public commitment in 2017 to show fishing activity from their Vessel Monitoring System (VMS) tracking data on our map we have engaged with local researchers and regulators to review and improve our data and analysis in the region. This began with a workshop with Peru’s Instituto del Mar de Peru (IMARPE) last December and now continues with Peruvian regulators directly responsible for daily monitoring of one of the world’s largest fisheries (Peruvian anchoveta).

In our most recent training session we highlighted the benefits of being able to view and compare multiple data sources on the Global Fishing Watch map including the new night lights and encounters layers launched in June this year. Many large fishing vessels on the Peruvian coast are covered both by AIS and the Peruvian VMS system. In training, we compared the tracking data from both systems for the same vessel showing how one system may cover a gap in the other.

The new night lights layer also has the potential to be very useful to regulators in combination with tracking data. A fleet of hundreds of Chinese vessels fishing for squid is expected to soon return to the Peruvian EEZ boundary. Individual fishing locations can be seen precisely due to the powerful lights they use to attract squid to the surface. However, to identify the fishing vessels, the night light information has to be combined with tracking and identity information from AIS. In training we identified a number of vessels in the Chinese squid fleet and followed their AIS tracks into port in Peru or to rendezvous with reefers (refrigerated cargo ships) where their catch is likely being transshipped.

As we work to develop new tools and data sources for the Global Fishing Watch map it’s valuable to get the insights of fisheries regulators on how they would like to be able to apply our map. So it was great to be able to wrap up the training with a discussion on features that it would be useful to enable in the future. These included being able to select an area on the map with the mouse and display a list of vessels inside and downloading reports of past activity for individual vessels as they come into port.

A special thanks to José Luis Herrera and Nilton Yarmas for coordinating the training. We also benefited greatly from the assistance of Eloy Aroni Sulca of Oceana’s Lima office who demonstrated many interesting potential applications of Global Fishing Watch in Peru. We look forward to hearing more in the future from participants in our training course and collaborating with them for successful monitoring and management of Peru’s ocean resources.
