Sorting out the history of whaling pressure on five populations of blue whales in the Indian Ocean and SW Pacific. So many years of work went into this monumental collaboration with many many coauthors. So pleased to see this paper finally published.

Blue whale news @bluewhalenews.bsky.social · Mar 19

Published! Our huge effort to obtain catch series for each of five overlapping populations of pygmy blue whales. Big collaboration with 30+ coauthors using spatial patterns of blue whale song (unique to each population) to figure out where each resides 1/n

Me (Trevor) to Hertz: hey you have a customer named John Doe who is using my email, please can you stop associating my email with their account?
Hertz [after a month]: Dear Mr John Doe, we have resolved this issue.

Sounds like this would be good written up as a blog post / scientific paper somewhere for others to copy. (Even just to copy the final agreed upon assignments!)

no time, please can you do it

BIG request: if you happen to sample further north and catch some Euphausia vallentini, can you get a nice photo of one? Doing a project and nobody at all has a picture!

Ours is missing: University of Washington, School of Aquatic and Fishery Sciences, annual stipend (not including 31.5% benefits rate) is $47,796 in 2026-27.
Biology Department should be the same rate (university wide)

Is it single-spaced too?

Trevor A. Branch @trevorabranch.bsky.social · 3d

Unfortunately not. We used to post on youtube, not sure if that is happening this year since budget cuts and we laid off our communications person.

Last term I tried an experiment: I walked into my Tech and Design Ethics class, admitted that I had *no idea* what to do about ChatGPT - so I would let them figure it out.

As in: their first project was to decide and write the ChatGPT policy for the class.

Here's what happened:

New paper out today in @natrevbiodiv.nature.com by the #GlobalSharkTrends team: Bending back the curve of shark & ray biodiversity loss;
Read the paper here: rdcu.be/eZ9n9
@sfu.ca
@sfubiosciences.bsky.social
@earth2ocean.bsky.social

Bending back the biodiversity loss curve of sharks and rays. The loss of sharks and rays to date has involved serial depletion of the largest, most evolutionary and functionally distinct species, and the increasing prevalence of smaller-bodied species that have benefited from release from predation.

Yeah we used to have permanent emails (with very tiny storage) but after moving to gmail, they get deleted on graduation. It's a stupid policy.

What’s a Human Life Worth? The E.P.A. Says Zero Dollars.

The Environmental Protection Agency has stopped estimating the dollar value of lives saved in the cost-benefit analyses for new pollution rules.

And/or when you write a paper use a permanent address (like gmail etc.) rather than an institutional one that expires when you leave (Univ Washington our emails expire!)... at least until you have a permanent position.

Healthy and sustainable fisheries have lower carbon emissions and fuel use, because fish are more abundant and easier to catch with less effort. Rebuilding fisheries and ensuring that fleet sizes are appropriate for catch level, are keys for CO2 reduction

Ice Age art!

A lovely little horse figurine sculpted from mammoth tusk around 15,000 years ago!

Known as ‘The Little Horse of Lourdes’ it was found in 1886 in the cave of Les Espélugues, Lourdes, Haute-Pyrénées, France. 📷 by me.

Shipworms aren’t worms. They’re bivalves that eat wood with the help of symbiotic bacteria turning wooden shipwrecks into functioning ecosystems. #MolluscMonday Fantastic image from seahistory.org/sea-history-...

MUST READ thread before Monday night's forecasted G4 / SEVERE geomagnetic storm. Auroras could be seen as far south as the U.S.-Mexico border at times. Widespread mid-latitude displays are possible. Here's what you need to know to have a successful aurora chase tonight! 🧵

Cow Tools!

We have lived alongside cows for nearly 10,000 years.
We breed them and exploit them

It is now, only now, that we have discovered THEY CAN USE TOOLS
