Also, we’re hosting an event this afternoon to share how researchers can access and apply our datasets—and to spotlight our Open Ocean Research Grants Program:

🌊 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.

🌊 Just launched: the Open Ocean Research Grant Program!

We’re offering up to $10k for individuals and $20k for teams using our data to tackle key ocean research questions.

Independent researchers & small teams welcome.

Editor's Choice - Global Fishing Watch overestimates pelagic fishing… | David Kroodsma 🎣  I was excited to read the ICES study, “Bias in Global Fishing Watch AIS Data Analyses Results in Overestimate of Northeast Atlantic Pelagic Fishing Impact.” - https://lnkd.in/eam2EN79 The paper ...

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

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.

That's a great question, and one I think we can probably answer in the next year or so.

I think the answers are "a meaningful amount" and "yes."

Mapping industrial vessel emissions at sea Pilot study first to estimate the greenhouse gas emissions of all large industrial vessels operating in the ocean

We are now estimating carbon dioxide emissions from all vessels at sea! Learn more here: globalfishingwatch.org/article/mapp...

Here is the BigQuery query to get this public data:

SELECT
date_diff(date, "2012-01-01", day) days,
floor(cell_ll_lat*4) lat_index,
sum(fishing_hours) fishing_hours
FROM
`global-fishing-watch.fishing_effort_v3.fleet_daily_100_v3`
where

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.

This is all vessels. And using imagery (sar or optical) up there is going to be horribly difficult because the density of vessels is low and the density of icebergs is high.

At some point I will get around to making this for more years than just 2019.

Yeah, that’s didn’t realize that either until I made the map. You can also see how critical those rivers in northern Russia must be for transportation—but only for half the year!

Nice! It is great to see this.

It has been almost three and a half years since Caldor, and given the three "mild" fire seasons since then, it's amazing how quickly I have forgotten about the risk posed by the forests behind my neighborhood. LA is reminding me.

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.

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

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.

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.

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.

With South Asia (which might be more than Europe once we include vessels without AIS) being at the bottom.

I think I like having the two areas of most intense vessel traffic -- Europe and East Asia -- on opposite sides of the map.
