A great overview, slightly dated since the NBP is already gone. The US Antarctic program capacity is lacking greatly right now....replacements that are in place now are a band-aid at best with less capacity/ability than the NBP and Gould. 🧪🌎🦑🌊 🇦🇶 #Antarctica
Replacing the Polar Research Vessel Nathaniel B. Palmer
The National Science Foundation ended its lease of Palmer at the end of FY 2025. Here's a look at what might be coming next.

More delays....and yet the fish keep swimming....saying they are not yet into the lakes is irresponsible. They're there. Now is when we keep the population numbers low...the longer we wait and delay, the worse/quicker the invasion will be. 🧪🌎
More delays for the Brandon Road Interbasin Project which aims to prevent invasive carp from entering the #GreatLakes

After Trump promised speed, Great Lakes carp barrier faces delay
Michigan and Illinois lawmakers say an unexplained federal review threatens to slow the long-awaited Lake Michigan invasive species protection project.

I actually have a question for science community that I HOPE someone can direct me...I have a species of marine organism that was previously described but while I'm sure I have collected this species, the original description, published in the 1993 is objectively not...ideal. 🧪🌎🦑🇦🇶

Happy Halloween! Today, I bring you one of the weirdest (and COOLEST!) creatures collected on our research trips ...a giant amphipod (Paraceradocus sp. I believe). They burrow in this slit-like holes in muddy sediments! Found on our research cruise to East Antarctica in 2023 (NBP23-03). 🦑🇦🇶🧪🦑🐧

"Science is being destroyed across many agencies" say federal researchers.
For my latest @nature.com piece, I spoke to 19 different scientists across EPA, NOAA, NIH, NASA, and USGS to document how science is being dismantled across US federal agencies.
