This week, there’s a very guilty looking western roughy… In other news, a paper “The commonness of of rarity in deep-sea taxon” has major implications for deep‐sea conversation, particularly in light of increasing anthropogenic threats to deep-ocean habitats. Discover how the dwarf sperm whale uses clicks to hunt for prey in the deep ocean. Glowing pelagic fauna have been caught on camera in the Norwegian Sea, helping us to understand more about this little-known but vast ecosystem, and Wurz et al. (2021) further our knowledge on the effects of elevated concentrations of sediment on filter-feeding sponges. The paper which has grabbed the headlines during the last two weeks is Homoky et al.’s “Iron colloids dominate sedimentary supply to the ocean interior”, demonstrating that it is lithogenic colloid production that fuels sedimentary iron supply away in the deep ocean, away from low-oxygen systems.

Plus lots of great events to sign up to, including our Climate Change webinar – you don’t want to miss it!
