Magic moment at the end of our LIVE dive today when a Dumbo octopus appeared in front of the hydrothermal chimneys at 2400 meter depth! 😮 Just....Wow
If you have missed our dive today on Loki's Castle, hydrothermal vents at 2400 meter depth, you can still watch it: www.youtube.com/watch?v=bMPJ...
We are back about 11 hours more south, and we are back on the western side of the mid-Atlantic Ridge, on another completely unexplored seamount: the “Boytsov Seamount” (Boytsov (1929–2004), a Russian hydrographer and Arctic researcher).
We just landed at 2400 meter depth 🙂
Gorgeous sea spider on the Arctic Schulz Bank Seamount, close to the Mid-Atlantic Ridge!

We are back LIVE, this time at "Aegir’s Spring” (Aegis Kilde), at 2300 m depth right on the Arctic mid-Atlantic Ridge. This hydrothermal vent site was discovered in 2015, and contains white and black smokers! Enjoy😊

Hi everyone, our third LIVE dive is now! Today we are on Mohns Treasure, an inactive sulfide mound at 2400-2800 m. Located 30 km southwest of the active Loki’s Castle vent field. We already saw this morning the iconic dumbo octopus 🐙 !

This natural product study started in 2018 and it took us a while to understand these #sponge #knottins! Peptides in deep-sea sponges are super interesting but challenging 😅 Congrats to the Gunasekera Lab in Uppsala 🙌
Sea conditions could not be better this morning in the Norwegian Sea 😊 We are now heading even more north (76 degrees North) to an unexplored mountain, so unexplored that it doesn't even have a name yet! We'll be the first humans there...⭐ @greenpeace.org @biodiversa.eu @sponbiodiv.bsky.social
Our Deep Arctic Expedition has now ended but you can still watch ALL of our deep-sea LIVE streams on youtube! 🐙

Two new activities for #barettin, extracted from my pet sponge 'Geodia barretti' : promising activity against 1) chronic pain and 2) the most common and aggressive type of pancreatic cancer! Two papers from the Cartmell Lab👇

Knottins are stable, structurally constrained mini-proteins with diverse bioactivities. This work presents the first report of a novel family of knottins, ‘stryphnines’, from the deep-sea sponge Stryp...
Despite increasing interest, there remain limited treatments for chronic pain, with opioids continuing to be one of the top prescribed medications. Marine natural products present a wealth of untapped potential for new treatments for chronic pain. In this study, we investigated the analgesic effects of the sea sponge ligand barettin in a mouse model of chemotherapy-induced peripheral neuropathy (CIPN). Barettin exhibited efficacious antihyperalgesic activity in male mice with no efficacy shown in females. Through the use of a PRESTO-Tango assay, we found that barettin acts as an inverse agonist at the 5HT2A receptor while also presenting no activity at the μ-opioid receptor. Head twitch experiments confirmed no hallucinogenic activity, suggesting that barettin may be a promising nonopioid, nonhallucinogenic, marine-derived therapeutic agent for the treatment of chronic pain.
