Impacts of Changing Winters on Lake Ecosystems Will Increase With Latitude Climate warming is particularly strong in winter and at high latitudes, driving changes in lake ice and snow cover. Using simple models, we show that the interaction between ice duration and seasonal....

Nice new work out in Ecology Letters by Ozersky and colleagues, showing that high latitude lakes will likely feel the greatest impacts of warming winters. onlinelibrary.wiley.com/doi/10.1111/... #winter #limnology

NSF plans abrupt end to lone U.S. Antarctic research icebreaker Imminent termination of the RV Nathaniel B. Palmer shocks polar scientists

The National Science Foundation plans to abruptly end operation of the RV Nathaniel B. Palmer, the sole U.S. research ship capable of braving the farthest reaches of Antarctica and the Southern Ocean. scim.ag/4mB8LOX

Are you an early-career biologist or ecologist who would benefit from an invited seminar? Would you like to come to UMaine next fall or spring to give a talk? Leave a brief comment with some info about what you do. I'm co-hosting our seminar series again, and am filling out our rosters.

Read the entire thread for extra fun.

Really helpful thread on today’s NSF Division of Earth Sciences webinar.

Our @noaa.gov funded team is getting after it on Lake Erie this week, with PhD student An leading sample collection like a pro. Great Lakes, great carbon, great microbes, great students!

I am sadly not at the @iaglr.bsky.social conference this week, but thanks to colleagues got some great photo evidence of my students sharing their posters!

Today on #World Environment Day, we’re launching 3 FREE courses on water sustainability: i) Climate change impacts on ice; ii) Indigenous relationships to water, and iii) Big data analytics. Enrol here: www.yorku.ca/research/wat...

Thank you to all of our contributors for sharing their expertise!

OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?

The State of Biodefense is beleaguered but resilient.

Watch below the Commission's State of Biodefense Address delivered by our Executive Director, Dr. Asha M. George, during yesterday's public meeting.

Exclusive: NSF faces radical shake-up as officials abolish its 37 divisions Changes seen as a response to presidential directives on what research to fund

Everyone needs to understand that dismantling NSF will have devastating long term consequences in our competitiveness and innovation in science, technology and beyond. 1/

I’m so pleased to see the important issues of planetary protection and biodefense being given attention, and honored to be part of the conversation. Many thanks to the Bipartisan Commission on Biodefense for your work.

So many horror movies right now!

Your NOAA $$ at work! We're funding @tjvmajors.bsky.social at MTU to coordinate a "winter grab" of hard-to-get water samples. Last week, our director @newelllab.bsky.social joined @nicolewagner.bsky.social and her students from Oakland University to collect samples under Lake St. Clair's ice. (1/2)

Felt great to get out in the field for #winter #limnology #GreatLakes-wide sampling on Lake St. Clair yesterday with @nicolewagner.bsky.social as part of a @miseagrant.bsky.social funded project led by @tjvmajors.bsky.social. Just happened to be an all-women team. #womeninSTEM

Yesss!! Go team!!

U.S. early-career researchers struggling amid chaos Uncertain funding, government firings, and distressed universities hit vulnerable groups especially hard

These students rock! A great day sampling for @miseagrant.bsky.social funded Great Lakes Winter Grab on Lake Superior. MI Sea Grant work is critical to the health and understanding of our largest source of freshwater, and we are proud to do the science they support!

Firings are happening right now at the National Science Foundation. Essential staff are being cut.

This isn’t about the budget. If it was, they’d be going after the military (17%) or state appropriations (38%). NSF is 0.7% of the federal budget. All federal employees make up only 4% of the budget.

Yes!! I just made this argument in a conversation.

National Institutes of Health radically cuts support to universities Sudden and drastic change will make it hard for researchers to keep the lights on.

Cutting overhead on new and existing grants will do dire damage to universities and scientific research.

Worried about losing access to US federal data that may go off-line, or already is? You’re not alone—but duplication isn’t the answer.

Many ongoing efforts have already archived key datasets and many more are ongoing. Check out these existing resources and, if you can, support their work. 🧵

Trump wants to cut the federal workforce. Who they are and what that means President Trump's efforts to cut the federal workforce by 10% might not save as much money as hoped and could have unintended consequences. NPR explains why.

The federal workforce does work that is critical to all of our every day lives. That work isn’t always visible. But we need you, federal employees! I know people are hurting or confused by the messages coming from OPM. Don’t resign. Hang in there. We see you, we appreciate you. You are not alone.

I see - thanks so much!

Any way you can clarify who is collecting the information going into the form? I like the coordinated phone calling idea, but that’s a lot of my info to put into a form that’s going to ?

The world has been through anti-science cycles before, to disastrous results

On a detour on my lit review, a mosey through the history of our familiar friend, the standard onion (Allium cepa) brought me right to one of botany's greatest cautionary tales of what happens when ideology overrides data

Evaluating the influence of snow and ice conditions on under‐ice light regimes, dissolved oxygen, and primary production in shallow lakes using controlled manipulative systems Shifts in hydroclimatic regimes associated with global climate change are affecting the timing and duration of winter ice-cover in temperate and high-latitude lakes. Less is known on how associated c....

Very excited to see some of my PhD work published after much (much) too long!

Using mesocosms and controlled ponds, we manipulated ice cover conditions and looked at the corresponding DO, light, and chlorophyll-a regimes.
