RRS James Cook is currently at the Porcupine Abyssal Plain Observatory (PAP-SO). The observatory is coordinated by the UK’s National Oceanography Centre, as part of CLASS (Climate Linked Atlantic Sector Science) funded by the Natural Environment Research Council. The aim of JC231 is to continue a timeseries of measurements that dates back to 1985. A UK Met Office buoy caries sensors and samplers to measure not just the atmosphere but seawater too. Other instruments capture conditions through the deep ocean and onto the seabed at 4850m. NOC aims to make the highest quality measurements through its involvement in projects such as the EU funded MINKE, https://minke.eu/ and research infrastructures such as ICOS (Integrated Carbon Observation, https://www.icos-cp.eu/ ). On JC231 we have various laboratories, where we set up equipment to make high quality measurements of ocean chemistry at sea. Pictured is the laboratory where dissolved oxygen, nutrients, and carbonate chemistry are made. We also spend many hours filtering for particulate carbon, chlorophyll, marine litter and biogenic silicate. You can follow the progress of JC231, and find out about the science and technology involved by reading the blog.
