Measuring the Footprint of Fisheries

Earlier this year we published in Science the first global assessment of fishing activity using AIS data, providing an unprecedented view into the activity of tens of thousands of large, industrial fishing vessels. We’ve made these fishing effort data publicly available, which is now leading a slew of advances in our understanding of fishing [...]

Machine learning and satellite data provide the first global view of transshipment activity

Nate Miller, Data Scientist, SkyTruth This week marks the publication of the first-ever global assessment of transshipment in a scientific journal. Researchers at Global Fishing Watch and SkyTruth, in the journal Frontiers of Marine Science, published “Identifying Global Patterns of Transshipment Behavior.” What is transshipment? Why does it matter? What have we [...]

Identification of ‘dark vessels’

Using bright lights to reveal the 'dark' fleet Christopher Elvidge with the U.S. National Oceanic and Atmospheric Administration (NOAA)’s Earth Observation Group writes about matching night-time imagery with monitoring data from fishing vessels to shed new light on the ‘dark’ fleet. The challenges with tracking vessels Vessel tracks from Automatic Identification System (AIS) and [...]

Satellite tracking shows the economics of much high seas fishing does not add up

Kristina M. Gjerde,  Senior High Seas Advisor. IUCN Global Marine and Polar Programme As the countdown continues to September’s historic first round of United Nations treaty talks on the conservation and sustainable use of marine biodiversity  in the high seas, science and technology are shedding increasingly compelling light on what is currently [...]

Adding Nano-Satellite Data Doubles Our Resolution

Today, we are pleased to announce that, through a partnership with Spire Global, Inc, we have doubled the amount of data we use to identify and track nearly 60,000 commercial fishing vessels on the world’s oceans. Publicly broadcast Automatic Identification System (AIS) messages received by satellites and ground-based receivers comprise the largest source of data in the [...]

What Can We See When AIS Signals Disappear?

We are often asked about how Global Fishing Watch can be effective when vessel captains can simply turn off their AIS. And our answer has always been, “they have to turn it back on sometime—especially when entering port, and intentional blackouts raise a red flag.” Our recent analysis of fleet activity around the Argentine EEZ [...]

AIS Gaps by Fleet

AIS GAPS BY FLEET: January 1, 2017 - July 10,2017 On the maps below, each point indicates the start of a gap in AIS signals from a fishing vessel lasting more than 24 hours. [Read about our AIS gap analysis around the Argentine Exclusive Economic Zone] Number of gaps by flag state:

Beta Release 2.0: Nearly Doubling our Database of Commercial Fishing Vessels

Since our launch in September, we have added 25,000 more fishing vessels to our database. Our new Beta release 2.0 now includes 60,000 fishing vessels. Although the number of fishing boats using AIS and the number of satellites receiving their signals have been steadily rising around the world, the vast majority of our gains have [...]

AIS for Safety and Tracking: A Brief History

The maritime Automatic Identification System (AIS) is a radio communications system by which vessels continuously broadcast their identity and position over public airwaves using unencrypted VHS radio signals. When it was developed almost 20 years ago, its primary purpose was to increase safety at sea: ships needed a better way to “see” each other and [...]

86,490 Points on a Map: All Potential Transshipments

5 years, over 86,000 potential transshipments In early 2017, we released an original report based on analysis of our data that revealed remarkable new insights about what goes on between fishing vessels at sea. The machine learning platform we developed found that over the past five years, there were more than 86,000 potential [...]

Transshipment: A Global Footprint Never Seen Before

It’s been just over five months since Global Fishing Watch launched publicly, and this week, we hope to make another splash by not just mapping global fishing activity, but by providing an unprecedented view of very specific activity by a very specific class of vessels around the world. Today, at the Economist World Ocean Summit [...]

Mystery Moves: What’s Up in the Pacific?

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, [...]

Making the Cut–Creating Our List of Fishing Vessels

This post has been adapted from “Updated Vessel Lists 0.2”  which appeared on our Data Blog for researchers and software engineers by David Kroodsma. Automating the process of identifying all industrial-scale fishing activity in near-real time on a global scale through AIS data is something that’s never been done. Inventing something new often means first [...]

Fishing Fleet Goes Home for the Holidays

'Tis the season, and even fishers want to be home for the holidays. The flag state filter in Global Fishing Watch allows us to select vessels flagged to a specific country or countries. In the spirit of the season, we decided to use it to see if  a cultural tradition that has nothing to do with fishing [...]
