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.
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.
Our collaboration with Global Fishing Watch on the problem of transshipment at sea in the fishing industry is at the forefront of a growing movement to take a critical look at this practice, which is increasingly regarded as a key driver of overfishing, and an enabler of illegal fishing and other fisheries crime including crew enslavement. Our work is funded by the Walton Family Foundation and being led by Bay-area skytruthers Aaron Roan and Nate Miller.

When Paul Woods moved to Shepherdstown, West Virginia, SkyTruth’s home base, he was looking to get away from the Washington, D.C. area where we had been consulting in the tech industry during the dot com boom. His goal had been to find a slower pace and a more soul-satisfying lifestyle than the world of maximizing profit margins through software development. Now, he’s setting off to help save the oceans by revolutionizing the way the fishing industry works.
As the Chief Technology Officer at SkyTruth, Paul was instrumental in bringing Global Fishing Watch into being. [You can read about that here] Now, the platform we developed for identifying and tracking every commercial fishing vessel on the oceans is spinning off into an independent non-profit organization with Paul at the helm. As the interim CEO of Global Fishing Watch, Paul will be guiding the new organization through the transition. While we’re still keeping him in the fold, we thought it was a good time to sit down for a brief reflection on his path, his time at SkyTruth and a look into what’s next.
It’s a small town, so I guess when you landed in Shepherdstown in 2001, it was only a matter of time before you and SkyTruth found each other. How did you get involved?
It’s true just about everybody in Shepherdstown knows SkyTruth. When I met John (SkyTruth President, John Amos), I was working with another company, but I did a few side projects for SkyTruth. I also joined the board as technology advisor. Then, as the other work was winding down and I was looking for the next thing, I realized I just got a lot more out of the SkyTruth stuff than I did out of creating products to maximize clicks or streamline business processes.
In 2010, when the Deepwater Horizon spill happened, I helped John set up a rapid response website. Of course the whole oil spill incident opened an opportunity for growth at SkyTruth, and I realized I could apply my skills in the stuff I really like doing directly to issues that made a real difference in the world. That kind of direct application to saving the environment is so much more satisfying than just writing a check or writing a letter to your congressman.
By 2013, I came on full time, and one of the first projects we did was SkyTruth Alerts, which is still in use today.
I’m sure it’s rewarding to see Global Fishing Watch mature into its own organization. Do you have any reflections to share as you look back at your time at SkyTruth?
Over the years I’ve been working on many different projects at SkyTruth that have been deeply rewarding to me. Now that one of those projects has gotten big enough that it requires all of my time and attention to keep it running, which is enormously exciting.
What are your hopes for the future:
Clearly my immediate hopes and dreams are focused on the continued success and growth of Global Fishing Watch. I hope to see Global Fishing Watch arrive at a long term sustainable model that will propel its growth beyond me and be wildly successful at making fishing sustainable and helping save the oceans.
Personally, I guess I’m always looking for the next thing. I’m a start-up guy. That’s what I do. It’s what I like to do, so I guess my hope is that there will be another Global Fishing Watch around the corner a few years from now —another project with the same great impact and the same great opportunity to make the world a better place, and I’ll get to be involved in it. There’s a good chance that project is in its infancy right now at SkyTruth.
If you could see any place in the world from space, where would it be?
Anyplace? Well, we have recently detected new planets only four-and-a-half light years away, and at least one of them potentially has liquid water on it. The surface of Proxima Centauri B. That’s my first answer.
Great answer. What about here on Earth. If you could aim the SkyTruth “eye” where would you aim?
What would be really fantastic to see from space would be the bottom of the ocean, the sea floor. Unfortunately we can’t do that right now, but I think that would be the place I’d want to see.
The government of Ghana has been giving permission to major multinational mining corporations to conduct surface mining operations, mostly for gold, in areas that had been set aside as forest reserves. Imagery from Google Earth tells the tale of one of these large operations, the Akyem mine operated by Newmont, a Colorado-based company. The rapid explosion in size of the operation is obvious. What’s less apparent is the magnitude of the impact on the adjacent forest reserve. (To be clear: the mining is obliterating the forest, like surface mining anywhere. But we can’t say how big an area of the reserve has been affected.) We don’t have reliable data defining the boundaries of the reserve, so we can’t quantify the destruction of protected forest due to mining activity. If we can find GIS-ready data showing the reserve boundaries, we’ll update this post.
Probable oil slicks on this Sentinel-1 radar satellite image, taken over the Taylor Energy site in the Gulf of Mexico at about 7:30 pm local time on February 14, caught our eye:
As usual, we can see a 9-mile-long slick emanating from that chronic oil leak that has been spilling oil continuously since 2004. The Taylor slick is drifting straight to the northeast away from the leak source on the seafloor. But the image is dominated by a thicker-looking 28-mile-long slick closer to shore. It seems to almost hook up with the Taylor slick on it’s east end, suggesting it could be a major continuation of the Taylor slick. This would make it one of the biggest slicks at Taylor we’ve ever observed; and if it is the Taylor slick, it makes a very unusual 180 degree turn. That’s possible, given the complex currents: outflow from the Mississippi River meets eddies spinning off the Gulf Stream, creating strong horizontal “shears” where the current on one side can be moving in a very different direction than on the other. But there may be a simpler explanation: this could be an oily slick caused by intentional bilge dumping from a moving vessel. Based on how the slick appears to be more pushed around by wind and current as you follow it back to the east, I’m guessing the vessel was moving from east to west, working its way around the tip of the Mississippi Delta parallel to shore.
Dumping oily bilge is illegal in US waters, and we don’t often see this here — although it is a big problem elsewhere. In this case, checking against our daily stream of Automatic Identification System (AIS) ship-tracking data, we haven’t been able to identify a possible culprit. There is a small bright spot near the west end of the slick that is probably a small vessel — there are no platforms or other structures at this location. This could be the culprit. But it wasn’t broadcasting an AIS signal.
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.
