We have a new paper in @iaglr.bsky.social on how the #GreatLakes research community could benefit from a coordinated basin-wide mesocosm network. A link between fieldwork/lab experiments, mesocosms could help us understand environmental variation across the basin authors.elsevier.com/c/1nxaV1MRgT...

More amazing sea spider video here from @schmidtocean.bsky.social shared by @tuexplorer1.bsky.social! Holding something....maybe a male holding on to its eggs? Most species of pycno demonstrate paternal care of egg masses. 🧪🌎🦑🌊

@schmidtocean.bsky.social and its team doing amazing work yet again, showing all the sea spiders! 🧪🌎🦑🌊

Margaret Hamilton empowered women and girls in science. 🧪 She made a tremendous impact on the world.

Sea spiders (species dependent) feed on soft bodied creatures....likely this Colossendeidae is looking for a snack of coral polyps! 🧪🌎🦑🌊 AMAZING video of these adorable creatures! Thanks for sharing @tuexplorer1.bsky.social

I've kept some of these (different species, same Family) in tanks in Antarctica and NEVER seen them move that fast nor seen them drop legs like this! 🧪🌎🦑 thanks @tuexplorer1.bsky.social for sharing this!

Colossendeidae! SPECTACULAR creature. 🧪🌎🦑🌊🇦🇶

This is a discussion point about AI (not this specific paper...but the general topic) that we should be having as professionals AND more importantly with our labs, our students, etc. 🧪🌎🌊

NEW SEA SPIDERS :) 🧪🌎🦑🌊 "...found in shallow waters in the Salish Sea, ...the first to be found in that area in more than 100 years..."

FAT BEAR WEEK FAT BEAR WEEK FAT BEAR WEEK FAT BEAR WEEK 🧪🌊🌎🦑

go work with Nathan Whelan! Great scientist and a great lab! 🧪🌎🦑

"NSF’s budget, adjusted for inflation, is essentially the same as it was 20 years ago, and Tr*** wants to cut it by half next year." not ONE BIT of this is realistically feasible and it is terrifying for the future of science in the U.S. 🧪🌎🌊

Sea spiders are the coolest :) 🧪🌎🦑🇦🇶🌊

NSF just announced its GRFP solicitation due in October - deadline varies by field: www.nsf.gov/funding/oppo... Now for the bad news... * NSF estimates they will issue 1,500 awards, down from 2,500+ last year. * NSF removed STEM Education and Learning Research as a Major Field.

Hi again all, yes....some non-science content here. If you could, votes for my daughter are appreciated. THANK YOU. athleteoftheyear.org/2026/madelin...

Little self promo here: my daughter is in the running for a youth athlete of the year award. If you are so kind, please go vote for her. Here’s the link.  athleteoftheyear.org/2026/madelin...

We are at a critical time for science...personalized cancer vaccines....changing climates and massive El Ninos...species discoveries....investigating/studying these is not possible in the U.S. without a well supported and robust NSF. This trend cannot continue. 🧪🌎🌊🌱

From the article: www.nature.com/articles/d41... I believe this figure is the most disturbing....we need to value science in the U.S., and we seemingly don't anymore. The world is not going to wait. We are falling behind and the next generation of scientists is going to suffer from this. 🧪🌎🧬🌊🌱

Invasive species don't wait around for construction to keep them out of the Great Lakes...go figure. 🧪🌎 Need to be proactive and not reactive!!!

Hardcore metal :) 🧪🌎🦑🇦🇶

The bighead and silver (aka Asian) carp have been swimming north into Lake MI for years....this was an effort to help protect the $multi-BILLION tourism, fishing, etc. industries in the region. This is VERY bad for not only MI but all Great lakes states and Canada. 🧪🦑🌎🧬

Interesting move: New attention on NSF Office of Polar Programs in the Senate: a bipartisan proposal to make OPP a permanent directorate within the NSF. From Senators Sullivan, Murkowski, & Hickenlooper. NSF OPP was under Geoscience directorate until it was moved into the Office of the Director. 🧪🌎🇦🇶

Giving an invasive species seminar to the St Ignace MI community library tonight! Yes. There will be jumping carp videos and eDNA! 🧪🌊🌎🦑🧬

Yet again life is better with sea spiders!!! 🧪🌎🦑🇦🇶

Kent Carpenter, my Ph.D. supervisor, was violently murdered in the Philippines. We hadn't spoken in many years, but I would not be where I am in my career without his early influence on my academic trajectory. His scientific impacts were far reaching, particularly in SE Asia marine biodiversity. 🧪🌎🌊

Life is better with sea spiders. Austropallene cornigera collected in #Antarctica. Isn’t it adorable!!! 🧪🌎🦑🇦🇶🌊

SPECTACULAR!!! A deep sea Colossendeidae! 🧪🦑

🦀 see a crab, post a sea spider....wait...I may be doing this wrong. 🧪🌎🦑🇦🇶 and c-🕷️

Massive extremes with huge global implications. Many organisms in Antarctic waters cannot survive temp shifts like this, particularly during larval development. 🧪🌎🇦🇶

My amazing friend, Dr. Chris Jerde (not on the socials).....was presented with a major award! So proud to know him and to be working with him still after all this time! No one deserves this award more than him. He's a spectacular scientist and an even better mentor and role model for students. 🧪🌎

The list of Ecology/Evolution/Marine Bio Labs recruiting grad students for Fall 2027 is live! PIs enter your position info here: forms.gle/MAGd4ohyPeoY... students (and PIs not recruiting) share the composite list: docs.google.com/spreadsheets... Please share widely! 🧪

From NSF...“aligns with N.S.F.’s wider strategy to have a nimbler approach to prioritizing support for evolving scientific priorities and emerging technologies as well as a deliberate approach to smart life cycle management within its portfolio of research infrastructure.” 🧪🌎

This one hits home to the Polar Programs community.... "NSF continues to offer fellowship opportunities ...in the fields of engineering, entrepreneurial research, mathematics and physical sciences. ..postdocs in biology are available only if they involve the use of artificial intelligence." 🧪🌎🇦🇶🌊

Arrow points to the oviger. Members of this family (colossendeidae) have palps and ovigers in males and females. These lay eggs on rocks (see Amy Morans recent pub). Arrow to oviger. 🧪🌎🌊🦑🇦🇶

Hi @andyantarctica.bsky.social, I have someone on board on the current @greenpeace.org ROV expedition asking for help narrowing down a species for this pycnogonid carrying babies. They're diving in Arctic Mid Ocean Ridge in Banana Hole. I said I'd ask you & report back. (Best pic I was given)

Everyone should read this.... AI and key words were used to cancel NIH and NSF grants...essentially on the whims of some DOGE folks on a power trip. The damage done to our once globally leading science enterprise is widespread...we need to speak out on this for it to get better. 🧪🌎

I mean….we care about science…so let’s make sure we have the leadership in there to oversee it for us right? This should NOT be politically partisan 🧪

I like to tell students how much scientific technology has improved...cheaper...faster...better data... in such a short time....and for the tech my field, no one had a larger impact than JCV. His impact knows no bounds. 🧪🌎🇦🇶🧬 www.npr.org/2026/04/30/n...

More info on the ouster of the National Science Board....with few awards made in 2026 to date, and we're already 5 months in....no board, no director/deputy director....where is future of fundamental science in the US ? 🧪

The National Science Board was created in 1950 with staggered 6 terms so that scientific research priorities would outlast any single administration. The statute says members must be chosen "solely on the basis of established records of distinguished service." www.forbes.com/sites/johndr...

hey @flavorflav.bsky.social as a father with a young daughter in sports THANK YOU for all you do....all the attention to women's sports....particularly in the less traditionally supported sports. You're an amazing human being.

🧪🌎 This needs to be a bigger news story than just seeing it as a social media post! More science under attack.

Scenery Friday from #Antarctica. On our 2020 research cruise along the Western Peninsula....penguins, cliffs, and some amazing waterfalls! 🧪🌎🦑🇦🇶🌊
