Less ice – more light. What will life be like in a bright, new Arctic? Earlier spring blooms mean less food in summer, when fish need it most. Polar cod in the Barents Sea are particularly vulnerable. 🧪 🌊 🦑 @oysteinvarpe.bsky.social @unibergen.bsky.social bjerknes.uib.no/en/news/en-l...

Mindre is – mer lys. Hvordan blir livet i et nytt og lysere Arktis? Tidligere algeoppblomstring betyr mindre mat om sommeren, når fisken trenger det mest. Polartorsken i Barentshavet er spesielt utsatt. @oysteinvarpe.bsky.social @bjerknes.uib.no @unibergen.bsky.social bjerknes.uib.no/aktuelt/en-l...

Energy content of krill and amphipods in the Barents Sea from summer to winter: variation across species and size - Polar Biology Arctic zooplankton develop large energy reserves, as an adaptation to strong seasonality, making them valuable prey items. We quantified the energy content (kJ g−1 dry weight) of abundant krill (arcto...

Dette er årsaka til at gåtefullt tjern i Stad skiftar farge Det går frå sitrongult, grønt til blodraudt. No har forskarar funne svaret på kvifor. – Ein litt morosam kuriositet.

Kudos to the university library in Oslo. Forbodne bøker. Ytringsfridom. Freedom of speech. #BannedBooksWeek

Same procedure as every autumn term, kicking it of with field course at #Espegrend, our UiB field station. BIO102 Basic Ecology and Field Methods. Keen students!

Visited Runde again today. The Northern Gannets, with their long breeding season, are still around. Decent number of recruits as far as I could judge through the binoculars. Morus bassanus, havsule.

One year jubilee for this rocky shore experiment. ‪@catiamonteiro.bsky.social‬‬ and @biointeractproj.bsky.social‬ visiting the Bergen site. Treated with a generous low tide. Ascophyllum removal and responses across latitudes. #Seasonality #Espegrend

NOAA firings hit the birthplace of weather and climate forecasting Dismissed researchers were improving severe weather predictions

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week.
