Final Science Meeting

A final science meeting for the Shelf Sea Biogeochemistry (SSB) programme was held at the University of Winchester, on Monday 5 June (10:00-18:00) and Tuesday 6 June (09:00-16:00). The purpose of the meeting was to collectively finalise the programme's scientific results, and to develop synthesis outputs and conclusions.

The presentations and posters presented at the meeting are now available as PDF documents for download.
