PurposeResearch
Objectives1. To undertake process measurements at sites in the Thames estuary and southern North Sea to determine the impact of land derived nutrients on the marine ecosystem (AE0529A0 and C956J168).
2. To undertake spatial surveys to determine the distribution of nutrients, phytoplankton indicators and other relevant parameters using CTD and underway sampling in the outer Thames estuary (AE0529A0 and C956J168).
3. To undertake process measurements at sites in Dundalk Bay, the Western 'Gyre' region and in Liverpool Bay in the Irish Sea (AE0529A0 and C956J168).
4. To undertake spatial surveys to determine the distribution of nutrients, phytoplankton indicators and other relevant parameters using CTD and underway sampling in the Irish Sea (AE0529A0 and C956J168).
5. To make bio-optical measurements at sites in the Irish Sea in support of the JoNuS and the Smart Biophysical Mooring Programme (CSG extra-mural).
6. To conduct trials of an Optical Nitrate Sensor (Southampton Oceanography Centre).
