Norge er verdensledende på hav. Hvorfor er da havet nesten borte fra bistands-debatten ? 🌊 Hvis regjeringen vil ha mer effekt av hver av bistandskronene, må den se til havet. Det er der Norge har mest å bidra med. les alt i kronikken vår i @dagensnaeringsliv.bsky.social www.dn.no/innlegg/fisk...

Venomous seasnakes are common here in the Bay of Bengal, and we have to be very careful sorting our trawl catches, handling any snakes we catch safely and with care. Our team is trained & we follow a strict protocal. After being weighed and photographed the snakes are released back to sea 🧪🦑🐍

We're using a camera system mounted in the trawl to see what passes through the trawl at different depths (DeepVision). A great tool to see what is actually in the different layers we see on the echosounder. (see this paper by my colleagues for more details: academic.oup.com/icesjms/arti...)

UN-Backed Study Highlights How Tracking Ocean Giants Advances Marine Conservation
A groundbreaking global initiative, known as MegaMove, has brought together nearly 400 scientists from over 50 countries in an unprecedented effort to map the space use of more than 110 species of marine megafauna. This collective endeavor, harnessing decades of sophisticated animal tracking data, represents the most extensive attempt to date to identify critical habitats and migratory corridors that these iconic ocean giants depend upon.
