Together with partners from around the world, SkyTruth uses the view from space to motivate people to protect the environment. SkyTruth is committed to transparency in all things. In the spirit of that, we wanted to share our annual report with you which covers the impact we’ve been able to have as a watchdog, innovator, and motivator for environmental good.
We’re excited to announce the 2015 update to our Pennsylvania FrackFinder data set! Using the USDA’s most recent high-resolution aerial imagery for Pennsylvania, we’ve updated our maps of the state’s drilling sites and wastewater impoundments. Our revised maps show Pennsylvania’s drilling sites and wastewater impoundments as of Fall 2015.
Our previous Pennsylvania FrackFinder project identified the location of active well pads in imagery from 2005, 2008, 2010 and 2013. We are pleased to add the 2015 update to this already rich data set.
The goal of our FrackFinder projects has always been to fill the gaps in publicly available information related to where fracking operations in the Marcellus and Utica Shale were taking place. Regrettably, there are often discrepancies between what’s on paper and what’s on the landscape. Permits for individual oil and gas wells are relatively accessible, but the permits are just approvals to drill: they don’t say if a site is active, when drilling and fracking began or ended, or if development of the drill site ever happened at all.
We compared permit locations against high-resolution aerial imagery from the USDA’s 2015 National Agricultural Inventory Program (NAIP) to determine whether drilling permits issued since the close of our last Pennsylvania FrackFinder project in 2013 were active. There were more than 4,500 drilling permits issued in Pennsylvania during our study period (May 1, 2012, to September 30, 2015), many of them located quite close together. Ultimately, we ended up with roughly 2,000 unique ‘clusters’ of drilling permits to investigate and map.
We look forward to seeing how the public will use these revised data sets. We hope researchers, NGOs and community advocates can use these unique data sets to gain a better understanding of the impact of fracking on Pennsylvania’s environment and public health.
We’ve launched the SkyTruth Spill Tracker, a map-based tool to allow citizens on the ground in Texas, Florida and the Caribbean to quickly report oil and hazardous waste spills and other pollution incidents as a result of the storms.
We operated a similar tool, the Gulf Oil Spill Tracker, during and after the BP oil spill in the Gulf in 2010. We also helped the Louisiana Bucket Brigade launch their iWitness Pollution Map. If you’re reporting pollution in Louisiana, you might prefer to use the iWitness map.
How to Submit a Report
Click the + symbol in the upper left corner of the map to report oil, chemical or hazardous waste spills. Follow the prompts to enter a brief description of what you see. If you are able, please upload a photo or video showing the incident and hit submit.
A technology-driven non-profit with a mission to protect the environment by making more of it visible, SkyTruth launched this reporting tool to enable citizens to report environmental pollution as a result of Hurricanes Harvey and Irma. Read more about related work after the BP oil spill, the Taylor Energy oil spill, and Hurricane Katrina.
We believe if people can easily communicate their needs, organizations and governments can more effectively respond. Federal and state authorities will be able to download the reports in a standard *.csv format, readable by any spreadsheet or database software.
With your help, the SkyTruthSpillTracker should prove to be a useful resource for aiding the response and recovery efforts throughout the U.S. and the Caribbean. We encourage everyone impacted by Hurricanes Harvey and Irma to use the tracker. We are also interested in coordinating with other groups organizing similar pollution reporting efforts on the ground. Please email suggestions to us at email@example.com.
The wasteful practice of flaring off natural gas from oil and gas fields is again making news, coinciding with a new release of SkyTruth’s Global Flaring Map that visualizes gas flaring activity around the globe. This map relies on the Nightfire data provided by NOAA’s Earth Observation Group, which has written extensively about their work detecting and characterizing sub-pixel hot sources using multispectral data collected globally, each night, by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi-NPP satellite. Read about the algorithm that creates Nightfire data here and methods for estimating flared gas volumes here.
SkyTruth’s enhanced map has these added features:
- NOAA has published two additional years of flaring data, allowing our map to extend back to March 2012.
- A location search box lets you go directly to a city, state, country, landmark, etc.
- Date range selection helps you limit the visualization to the time-frame of interest.
- You can identify your rectangular Area of Interest and download flaring data within that AOI (works best in Chrome browsers).
- We’ve caught up with NOAA’s daily download after adjusting to recent changes in their web security.
About our Global Flaring Map
Please read about some of the uses for this map and how SkyTruth processes NOAA’s data in this original post describing our map. If you don’t see a flaring detection you expected to see, consider the caveats: some flares don’t burn hot enough to be included in our dataset, they may not have been burning when the satellite passed overhead, the flare may not be frequent enough to make it past the 3 detection threshold, heavy clouds may have obscured the flare from the sensor, etc.

Why Flaring is In the News Again
In November 2016 the Interior Department announced a new Methane and Waste Prevention Rule to reduce wasteful flaring and leaks of natural gas from oil and gas operations on public and Indian lands. Although Congress tried repealing the rule after the 2016 elections, that effort failed to advance out of the Senate after a May 2017 vote.
Despite the Senate’s action to keep the methane rule, the Environmental Protection Agency just announced (as of 6/15/2017) they would suspend implementation of the rule for 90 days — an action leading environmental groups claim is unlawful.
In January, SkyTruth reported on our work with DigitalGlobe to identify and photograph refrigerated cargo vessels (reefers) in the Western Indian Ocean. The goal was to capture high-resolution images of vessels that our analyst had painstakingly targeted for suspicious behavior by monitoring and analyzing their movements based on signals from their Automatic Identification System (AIS) broadcasts. We targeted reefers because they are key to transshipment—they receive catch transferred from multiple fishing vessels and carry it to port. The practice, called transshipment, saves fishing vessels time and fuel, but it is illegal in many cases because it can enable illegally caught fish to be mixed with legal catch.
The images DigitalGlobe acquired in November revealed multiple instances of reefers in rendezvous with other vessels, including fishing vessels. Now, in collaboration with Global Fishing Watch, SkyTruth data scientists have made the job of targeting reefers much easier. Together, the team has developed an artificial intelligence system capable of identifying and tracking transshipments around the world by following reefers and classifying their movements. An analysis of 21 billion AIS signals from ships at sea has created the first-ever global map of transshipment.
Today, SkyTruth and Global Fishing Watch are publishing those results in a new report: The Global View of Transshipment: Preliminary Findings. According to our analysis, from 2012 through 2016, there were more than 86,490 potential transshipments in which reefers exhibited the slow movements indicative of transshipment. Of those, 5,065 were likely transshipments because they included a rendezvous with an AIS-broadcasting fishing vessel — meaning they traveled at a specified slow speed in close proximity to one another for a certain length of time that indicated a likely transshipment.
Like most activity that occurs on the ocean, transshipment has been hidden from the world. This report shines a new light over the horizon, revealing the extent and magnitude of transshipment. Based on the data generated by SkyTruth and Global Fishing Watch during this project, our partners at Oceana are publishing a complementary report today that highlights the global scale of transshipment and its complicity in illegal fishing and human rights abuses. The report identifies hotspots of transshipment and the ports that reefers visit, exposing associations between transshipment and illegal, unregulated and unreported (IUU) fishing activity.
Oceana’s report calls for the banning of transshipment at sea, expanded mandates for unique identifiers and vessel tracking for fishing vessels. Currently AIS is not required on all vessels, and fishing vessels engaged in illegal activity are known to turn off their AIS when they don’t want to be seen. Having access to high-resolution satellite imagery is a game-changer when it comes to illuminating these rendezvous, especially when only one of the vessels is broadcasting AIS. That’s why we are thrilled to be working with the folks at DigitalGlobe, who are donating time and imagery from their powerful WorldView satellites to demonstrate that we can systematically shine a spotlight on these transshipment events at sea. In partnering with SkyTruth, DigitalGlobe shows how corporations and nonprofits can join together to solve some of the world’s thorniest problems.
Over the past couple of months, SkyTruth analyst Bjorn Bergman has been watching some interesting activity by the Chinese fishing fleet in the Pacific. A large Chinese flagged squid-fishing fleet had been fishing at the boundary of Peru’s exclusive economic zone (EEZ) throughout the summer and fall of 2016. Then, near the middle of December, many of them suddenly began migrating some 3,000 miles to the northwest.
At their new location, around 118 degrees West longitude and just north of the equator, they met up with another group of Chinese-flagged vessels. These vessels had just moved to this remote part of the Pacific about a week or two earlier. Some arrived from China and Indonesia, and some came directly from fishing just outside the Japanese EEZ.
The same pattern is seen using satellite signals from fishing vessels.
The new location of these vessels is not known for squid. It is also an unlikely habitat as squid usually live near continental shelves and canyons where there are steep changes in water depth. It’s unclear what the vessels are fishing for now, but the sudden move from the eastern Pacific may be a reflection of a dwindling catch.
Usually Chinese flagged squid fishers operating around South America concentrate off of Peru in the Pacific and Argentina in the Atlantic Ocean. For the past few years, some squid-fishing fleets have seen their catch decline in both regions. Undercurrent News reports that some Taiwanese boat captains abandoned squid altogether because of low catch. They are now targeting Pacific saury (mackerel pike), which is found in the north Pacific.
Perhaps the Chinese fleet around South America has also given up on catching squid. We noted that when many of the Chinese vessels off Peru began moving to the northwest, some of them turned south, headed for Argentina, but according to Undercurrent, Chinese captains who moved to Argentina said they wish they had stayed in Peru because the catch was so bad.
The fleet that stayed in Peru may not have fared much better. By February 7, only three Chinese squid-fishing vessels remained in that location. Why so many have moved some 3,000 km to the northwest, and what they’re fishing for now remains a mystery to us. Whatever it is, it’s also drawn a crowd of Chinese vessels from the western Pacific. We checked in with the Southern Pacific Regional Management Organization that has jurisdiction over the area, and even they are not sure what the sudden change in location by this fleet means.
We would be very interested to hear from anyone who can help explain it.

Despite a dearth of monitoring and law enforcement in the remote Saya de Malha bank, there’s nothing secret about what’s going on in this distant area of the Indian Ocean east of Madagascar.
Last month, Greenpeace published a report asserting that a significant number of Thai fishing vessels have repeatedly moved their operations, which were shown to include illegal fishing and human trafficking, to evade detection and capture, and that they may now be acting with impunity on the Saya de Malha bank more than 7,000 km from their home port in Thailand.
As we know, seeing is believing, and in collaboration with DigitalGlobe, we have obtained high-resolution satellite images that corroborate Greenpeace’s assertions and reveal just how active the fleet is. Since November, we have documented Thai vessels gathering in one specific location on the Saya de Malha bank for the apparent transfer of fish.
The report, “Turn the Tide: Human Rights Abuse and Illegal Fishing of Thailand’s Overseas Fishing Industry,” outlines the Thai fleet’s exodus: first from their staple fishing grounds in Indonesian waters to a remote region off of Papua New Guinea, then to the Saya de Malha Bank. The evasive moves correspond to the hardline stance against illegal fishing by Indonesia in 2014 that included blowing up illegal vessels, and to subsequent increases in enforcement by Papua New Guinea in August of 2015.
The imagery we’ve captured from Saya de Malha Bank is part of a larger effort to gather high resolution satellite imagery of ocean surface around refrigerated cargo vessels in different parts of the world. With their large carrying capacity, these refrigerated vessels, called “reefers,” collect catch from multiple fishing vessels for transport to shore.
Not only does this type of transshipment allow the fishing fleet to continue working the fishing grounds for months, or even years at a time, but it facilitates the mixing of legal and illegal catch, which is why it is prohibited in many circumstances. What’s more, fishing vessels that remain at sea almost indefinitely have greater potential for abusive labor practices, including the enslavement of crew. The move by the Thai fleet to Saya de Malha almost requires the use of reefers as an efficient way of transporting catch to the home port from such distant fishing grounds.
Using AIS signals from known reefer vessels, we identified precise locations for aiming DigitalGlobe’s satellite sensors. With the knowledge that fishing vessels often don’t broadcast AIS while engaged in illegal activities such as unauthorized transshipment, we were interested in finding out if we could capture suspect vessels using imagery in the vicinity of a reefer.
One of the reefers we chose for imaging, the Thai vessel Leelawadee, seemed a good target. “I saw that it was stopped at the north end of the bank,” says our analyst Bjorn Bergman. “It’s in a location where it may be shallow enough to anchor.” In addition, Bjorn had documented a possible transshipment between the Leelawadee and an unnamed vessel in 2015. That event was documented using AIS data as part of SkyTruth’s assistance with the investigation by the Associated Press into Thai vessels fishing with trafficked and enslaved crews. It is no surprise that it occurred in the waters of Papua New Guinea.
The first image of Leelawadee on the Saya de Malha bank was captured on Nov 23, 2016. It showed her alongside a refueling vessel, the Mahachai Marine 1. Refueling at sea, also known as “bunkering,” is another necessity for fishing vessels operating far from their home ports for extended periods of time.
Seven days later, on the November 30, the satellite captured five vessels in one pass: the Leelawadee with two vessels tied alongside her and a vessel tied to the stern of the Mahachai Marine 1 (see images below). Although the three unknown vessels appear to be fishing boats, none were broadcasting AIS signals.
Since we began our efforts to target imaging satellites on reefers, we have turned up several similar “dark” fleets of fishing vessels in other parts of the Indian Ocean and the Atlantic. Combined with AIS data, we are able to flesh out an even more complete picture of what these vessels are doing. In the case of the Leelawadee, AIS-derived tracks over four years indicate that she has made repeated trips between Thailand and an area inside Papua New Guinea’s exclusive economic zone known as The Dogleg, a poorly monitored, remote region rife with suspected illegal activity. Our data reveals many instances in which vessels have crossed from Indonesian waters into the Dogleg, likely to transship their catch. On July 29, 2015, the Leelawadee rendezvoused for many hours with an unnamed fishing vessel broadcasting an irregular AIS number not tied to a vessel identity.
Then in November 2016, both vessels met again, this time on the Saya de Malha bank. They spent several hours together, indicating a possible transshipment. That rendezvous occurred hours after we captured the photograph of the Leelawadee with two “dark” vessels tied alongside, and right before she left the area on a northeasterly course back to port in Thailand.
“That both vessels were seen in the Dogleg, and have now moved to the Saya de Malha Bank provides tangible evidence to support the Greenpeace report” says Bjorn. “And what’s interesting is the pattern is similar to the situation we saw with the AP investigation where these Thai reefers would return again and again to one particular location.” It’s worth noting that the encounter between the Leelawadee and the unnamed vessel that occurred in the Dogleg also followed a transshipment that was photographed in the same location by DigitalGlobe. That photograph led to the capture of the reefer Silver Sea 2, which reportedly had been receiving catch from fishing vessels with enslaved crew. [Read our earlier post on this investigation.]
