🌊 I’m really enjoying the One Ocean Science Congress in Nice, France this week, in the lead-up to the UN Ocean Conference next week. If you’re in Nice and interested in using Global Fishing Watch data or tools, feel free to reach out!

Just under one month left to apply for a grant through the Open Ocean Research Grant Program!

Open Ocean Research Grants Program

This research grant program aims to enhance ocean governance by publicly sharing data on human activity at sea to grow our community of practice and expand and improve Global Fishing Watch datasets.

A new paper said our fishing algorithm overestimates effort! academic.oup.com/icesjms/arti... However, it is based on how you interpret our algorithm. I think this paper interprets our algorithm incorrectly, but it may be our fault that we did not better communicate how to use our algorithm.

Bias in Global Fishing Watch AIS data analyses results in overestimate of Northeast Atlantic pelagic fishing impact

Abstract. The ability to pinpoint fishing activity in the world’s oceans has greatly improved over the past decades, a period in which both satellite-based

We have just updated our public fishing activity data. You can now download data for 2012-2024! Learn more: globalfishingwatch.org/insights/ask... Here is fishing effort by latitude and day, across 12 years.

Currently on a flight to Tokyo -- amazed to have wifi over the middle of the Pacific (even if it is slow). Looking forward to meetings in Tokyo, then Taiwan, then Korea, over the next eight days. Here's an image of fishing from AIS data in the region.

Seeing friends and colleagues abandon their homes and flee the smoke and fire is bringing back painful memories of when we had to evacuate for the Caldor fire in 2021. It feels like no one is safe. Thinking of everyone in LA.

And because very extra 0.1 degree of warming is worse than the one before it, it is actually more important, not less.

Occasional reminder that there’s no, “it’s too late, its over” for anthropogenic climate change. Every molecule of CO2 that doesn’t go into the atmosphere makes a difference. Preventing 0.1 degree of warming makes a difference. Every bit of climate resilience we build together makes a difference.

We are currently trying to come up with a name for this new map projection. Any suggestions? Shown is vessel activity from AIS.

Same data again, but in a new Elastic projection I've been experimenting with that avoids disintegrating Australia.

If you follow us at Global Fishing Watch, be prepared to start seeing more maps with this projection :-). It is conceptually like Spilhaus, but with less distortion along the global coastline.

We are starting interviews for our new Senior Scientist, Head of Research Impact role. We have 105 candidates on the recruiting "short list", so this might take a while😅. Applications close tomorrow, so share if you know someone we should be talking to. job-boards.greenhouse.io/globalfishin...

Two weeks ago I said "hey we should use this crazy new map projection" and today there is python code! Showing here global vessel presence density (from AIS) using the spilhaus projection in a single view where you can see the whole ocean.

Tim@tim.hochberg.io · 2y ago

@paulwoods.io I put together some code at github.com/GlobalFishin... that should be fairly self contained.

I have a new analysis over at The Climate Brink exploring how rates of warming have changed over the past century. Post-1970, GHGs (CO2, CH4, etc.) would have led to just under 0.2C per decade, but falling aerosols (SO2) have increased that rate to 0.25C. www.theclimatebrink....

Very happy with the work we are doing with @odihq.bsky.social to develop a robust data ethics practice to complement our use of AI, especially as we evolve to detecting smaller and smaller vessels. Read more in the ODI blog

Today at Global Fishing Watch, on Slack, we are discussing the best map projections for showing off the ocean (this is partially us procrastinating). Our default is an equal earth projection. But some argue we should use the Spilhaus projection instead, which is how "fish see the world."

@paulwoods.io @davidkroodsma.bsky.social I played around with this over break and managed to map vessel presence in the Spilhaus projection. It really shows how little vessel traffic the southern oceans have. It's also a good candidate for a black light poster with this color scheme.

Paul Woods@paulwoods.io · 2y ago

We should add this projection as an option in our pyseas python mapping library 😁 Wdyt @davidkroodsma.bsky.social github.com/GlobalFishin...

One of my resolutions for 2025 will be to share more of the maps we make at Global Fishing Watch. Here is all vessel traffic from AIS across five years. And if you want a 50 megabyte file of this image where you can zoom in to really high resolution, go here: drive.google.com/file/d/1RgBQ...

It’s interesting that the emojis show the earth from three angles 🌎 🌍 🌏 but not the fourth. Though 🔵 is a fair approximation of what it would look like. People underestimate the Pacific.

In addition to oil slicks, we will also use this satellite to find dark vessels that are trying to avoid being tracked thanks to ESA #remotesensing

I really enjoyed this paper – the first global assessment of preferential access areas (PAAs), which are areas, usually along the coastline, where small-scale fishers are given preferential access to fish. Over 44 countries have PAAs! www.nature.com/articles/s44...
