“They got it!!”
Late in the afternoon on July 14, an investigative journalist from the Associated Press (AP) informed SkyTruth that over three months of research, behavioral analysis, and satellite vessel tracking had culminated in photographic evidence of a refrigerated cargo ship receiving transshipments at sea from fishing vessels believed to be crewed by slave labor. [UPDATE: On August 12, the Silver Sea 2 was seized and brought to shore by the Indonesian Navy, pending further investigation.]

Thanks to daring investigative journalism supported by data-driven intelligence from SkyTruth, the lawlessness of the high seas has recently been making major headlines. In March, the AP published the results of a year-long investigation that revealed slave-caught seafood in the supply chains of major American supermarkets. Their stories traced the repatriation of one Myanmar fisherman after 22 years separated from his family, and prompted the rescue of hundreds of migrant fishermen from captivity on remote Indonesian islands. Last month, in a tour-de-force of international journalism, the New York Times exposed the contemptible track record of the Dona Liberta, a name-changing, flag-switching cargo ship that we observed spilling oil off the coast of Angola back in 2012. The Times investigation also explored slavery, murder, and poaching on the high seas in their four-part series The Outlaw Ocean.In April, SkyTruth began monitoring more than half a dozen vessels suspected to be involved in the trafficking and enslavement of Burmese migrants on fishing boats working the sea off Southeast Asia.
Through careful analysis of satellite-derived vessel location data over a six-month period, we were able to help the AP acquire the satellite image above, capturing an apparent transshipment at sea, where fish are transferred from one vessel to another. Many of the fishing vessels we are interested in are exempt from broadcasting their location via the Automatic Identification System (AIS), but because they stay at sea for months at a time, must regularly offload their catch to refrigerated cargo ships (also known as “reefers”) like the Silver Sea 2. For safety reasons, large ships including reefers are required by international law to broadcast their identity, location and speed via AIS, giving us a way to catch a glimpse of the shadowy world of transshipments at sea.

For three weeks the Silver Sea 2 lingered in a region of Papua New Guinea’s Exclusive Economic Zone (EEZ) called the Dog Leg. During this time, the reefer stopped broadcasting its location and was presumably receiving shipments of seafood from trawlers operating in the area. On May 17, the Silver Sea 2 turned its AIS transponder back on and headed west, destined for Indonesia and Thailand. Looking back in time, we found evidence of two other Silver Sea reefers making this same circuit. Armed with intelligence that revealed a predictable pattern, our team was optimistic that we might be able to get a satellite snapshot of the “Dark Fleet” that was offloading fish to the Silver Sea reefers.
Intentionally collecting a high-resolution satellite image of a fishing boat underway at sea is difficult. Transshipments, however, are another story: reefers are stationary, or moving very slowly and predictably, for hours to days at a time while they receive catch from vessels in the area. There is still a possibility that clouds could obscure the target, or no fishing vessels are alongside at the moment the satellite flies overhead, but the odds of success are better.
On July 13th we notified AP that Silver Sea 2 was returning, following the same pattern we observed in April. Another Thai reefer, the Sea Network, was also anchored in this coastal transshipment area. With two reefers likely transshiping catch, the time was ripe to go for it. Later that day, the WorldView-3 satellite collected an image of Silver Sea 2 rendezvousing with two vessels believed to be part of the slave fleet previously operating out of Benjina.

The Silver Sea 2 is now well under way toward Thailand, but news of this transshipment being spotted by satellite appears to have prompted authorities step up their efforts. Another Thai cargo ship, Blissful Reefer, has been detained and eight more fishermen have been freed from purported slavery at sea.

On September 15, 2016, at the Our Ocean Conference in Washington, DC. Actor and ocean advocate Leonardo DiCaprio announced in his remarks to the conference that Global Fishing Watch is now free and open to the public, and U.S. Secretary of State John Kerry personally received a demonstration of the tool from the Oceana, SkyTruth, and Google team.

According to satellite AIS data, the vessel is 10 miles SE of the coast, and slowly drifting almost due north at an average speed of 2.87 knots (3.3 mph) over the last 9 hours. Weather reports referenced by the Haida Nation stated, “Thirty-five to forty-five [MPH?] south-east winds are blowing the vessel to shore in a 7-10 metre sea.” However the release also stated that the winds are expected to turn westerly in the afternoon.
This trajectory clears the coastline by 4 miles, again in the early hours of tomorrow morning.
However, ocean currents and winds do not follow straight lines, so reality will almost certainly be somewhat different than these projections. Thankfully, nearby vessels like the North Star, an 839 foot American container ship, are closing in on the stricken ship to assist it. Additionally, the Gordon Reid, a Coast Guard Patrol Vessel, is only 21 miles away and closing fast. The Reid was originally reported to be 750 km (466 mi) away. This post will be updated as details unfold.
We’ve been looking at satellite imagery of offshore Brazil regularly since Chevron’s November 2011 blowout and spill in the Campos Basin. Yesterday Teri noticed what appears to be a 40-mile-long, thin slick about 50 miles offshore in the southern part of the Campos oil field, playing hide-and-seek between the clouds and cloud shadows, on a MODIS/Terra satellite image:

Given the location, one might suspect this is a leak from one of the many oil platforms or FPSOs in this area, shown as purple dots in the image above. Petrobras platform Namorado-2 is located close to the north end of this slick. But we think, given it’s length and consistent width, this is more likely a bilge-dumping slick or leak from a passing vessel than a leak from a platform.
Is bilge dumping legal in Brazilian waters? And who is the culprit? There is plenty of coastal shipping activity in this area, including cargo ships that we’ve caught dumping bilge elsewhere. There is also a lot of tanker traffic here, hauling oil from the FPSOs offshore to storage facilities and refineries onshore, occasionally causing spills here in Brazilian waters.
If we had to place a bet, we would guess this is bilge dumping from a shuttle tanker serving the Campos Basin oil facilities. Teri is running through the AIS data now to see if she can identify the source of this slick.
