The decomposition dynamics of 3 important #kelp species in the Northeast Atlantic with focus on the loss of dissolved carbon. We found that DOC is released in large amounts initially, providing valuable data around the complex processes involved in #carbon cycling of kelps.

On #InternationalDayOfForests, let's consider the forests we don't often see.

Kelp forests in our seas act as nurseries and food sources, provide coastline protection and absorb CO2.

Yeah I see that! I think we have Coryphella browni here. C. pellucida is a bit bigger I think

Carronella pellucida is one of the most special nudibranchs we have in Scotland. Especially under blue lights! Check out this one from Loch Creran

Yeah some of them have the fluorescent proteins, it's really fun trying to get them to glow! I use a blue light and yellow filter for the photos. Cool book!

Another #fluorescent beauty, the grey sea slug (Aeolidia papillosa) is anything but grey under blue lights! This #nudibranch is quite common in #Scotland
