Ship name (ship code) | RV Prince Madog (74P2) |
Cruise identifier | PD13/12 |
Cruise period | 2012-02-14 — 2012-02-17 |
Status | Completed |
Port of departure | Liverpool, United Kingdom |
Port of return | Liverpool, United Kingdom |
Purpose | Research |
Objectives | Two moorings are maintained at the Mersey Bar Station (MBS). Instruments are mounted in a sea bed frame, and at 5 m below a spar buoy and along its mooring chain. Maintaining a long time series of observations will ultimately facilitate the determination of natural and anthropogenic variability within Liverpool Bay. The primary aim of the cruise is to recover and redeploy this instrumentation.
The second cruise objective is to complete a 13-hour station of half-hourly conductivity, temperature and depth (CTD) profiles, and running concurrent to the start of the spar buoy deployment. Water samples were obtained in Niskin bottles at on-the-hour profiles for determining concentrations of: suspended particulate matter (SPM), chlorophyll-a and chromophoric or coloured dissolved organic matter (CDOM) and nutrients near the sea bed, 5 m below the sea surface, and near-surface. |
