It’s been a busy year in plankton science for policy in the UK and OSPAR. Much of our work focused on further developing our ability to assess the state of pelagic habitats through the Improving Confidence Evaluating GES for Regional Assessments of Pelagic Habitats (ICEGRAPH) project. ICEGRAPH is an EU-funded project, led by University of Plymouth, in collaboration with the UK’s key plankton monitoring time-series. Below we’ve highlighted our key results and achievements. Here’s to an even more productive 2020!
