This cruise proposes to build upon the oceanographic and ecosystem data collection efforts of the past decade to understand the dynamics of living and non-living resources on the Irish continental shelf.The cruise has the following key objectives. - Collect CTD profile data using a CTD Rosette sampling system along the standard offshore and shelf sections to include: o Nutrient sampling o Phytoplankton samples o Salinity samples o Collect CO2 samples on the cruise - Undertake Continuous Plankton Recorder Tows in Irish waters to contribute to the SAHFOS CPR Global effort (analysis by NUI, Galway) - Acquire Acoustic Doppler Current Profiler (ADCP) data on the shelf to validate model output - Collect size-fractionated baseline data on marine plankton to assess whether it can be used in monitoring of trophic status (different phytoplankton net mesh sizes will be used to achieve this). - Deploy the MI Glider on first shelf trial missions. Deploy the Belmullet Fugro Weather Buoy Deploy an ADCP at the belmullet site.
