Untangling the complexities of larval Antarctic krill overwintering success under climate change Abstract. Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked to high po

I'm so proud of the wonderful team I got to help design and write this paper with.
Understanding larval #krill is incredibly important for understanding krill's impact on the #Antarctic ecosystem at every life stage.

Graph showing global average temperature anomaly in the upper 2000 m of the ocean as measured by the Argo float array. Anomaly is near zero (blue tint) until about 2013 and becomes progressively more red (warmer) up until present. Increasing ocean heat content in response to climate change is the cause.

The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.

@noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!

🔮 What does the future hold for our oceans and their ability to soak up carbon from the atmosphere?

That's what a team of scientists are hoping to learn more about, as they embark on a 51 day voyage around the Southern Ocean. 🌊

It's time for a thread 🧵

Language-like efficiency in whale communication Whale vocalizations follow efficiency rules seen in human language, revealing striking similarities in communication systems.

Do whales optimize their vocalizations for efficiency, just like human language? 🐋🎶 My latest study in
Science Advances (@science.org) suggests they do—following linguistic laws seen in human speech. 🧵 www.science.org/doi/10.1126/...

Drumpf and co are trying to remove and ban all mentions of #LGBTQ terminology in #medical journal articles.
Very similar to the mass book burning on #trans #science by Hitler.
