Due to reorganisation, The British Science Association no longer has regional branches. We are hoping to replace SciBar with a new event at The Ship & Mitre.
The teams that study cold water corals have a ship and remotely operated vehicle. They study the corals, water composition and things like stable isotopes #scibar#coral@Theshipandmitre
One thing that could control distribution of cold water reefs is the distribution of fatty acids. These cannot be synthesised so an abundance of them would be very beneficial #scibar#coral@Theshipandmitre
There are various currents which 'cascade' water over cold water reefs and concentrate organic particles over the areas enabling them to grow even if the substrate isn't ideal #scibar#coral@Theshipandmitre
Cold water corals need something to attach to just like hot water ones. The distribution of this substrate is very important #scibar#coral@Theshipandmitre
Part 2 is about to begin and Kostas is going to start with the global distribution of cold water coral reefs. There is a high density of reefs in the NE Atlantic. However this could just reflect a bias in mapping #scibar#coral@Theshipandmitre
Important announcement time. Tonight is the last scibar we will have for a while. Keep your eyes on the Facebook page and here and more info will follow
Ocean temperature increase has now been measured down to 700m. This is well within the depth range of cold water corals. The temperature increase is likely to increase their energy demands but they may not be able to keep up with this #scibar#coral@Theshipandmitre
One way to protect cold water coral reefs is to declare them marine protected areas or MPAs. The Darwin Mounds are off the north west coast of Scotland and they are in an MPA. Despite that they have still been trawled. #scibar#coral@Theshipandmitre
Threats to cold water reefs include hydrocarbon exploration and production, pollution, global warming and bottom trawling. The last one is the most worrying and destructive. #scibar#coral@Theshipandmitre
The threats to cold water coral reefs are many and they are very vulnerable. They take much longer to regrow and are slow to reproduce and become sexually mature @Theshipandmitre#scibar#coral
Why care about cold water coral reefs? Commercial fish species use them as nurseries, they are hotspots for carbon recycling and there is potential for new medicines #scibar#coral@Theshipandmitre
The biggest cold water reef is Røst reef in Norway and it is 35km long and 3km wide. Cold water reefs are incredibly diverse ecosystems just the same as tropical reef systems #scibar#coral@Theshipandmitre
Deep coral reefs were first described by Linneaus in the 18th century but they were considered oddities. It was thought that they could not exist due to unfavourable chemistry and energy limitations #scibar#coral@Theshipandmitre
