Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D352 |
|---|---|
| Short name | D352 |
| Objectives and Narrative |
RRS Discovery cruise D352 was supported as part of a NERC Responsive Mode research project ("A Thermocline Nutrient Pump", NE/F002432/1) awarded to Bangor University (Dr. Tom Rippeth) and the Proudman Oceanographic Laboratory (Prof. Jonathan Sharples, now at the University of Liverpool).
The focus of the project, and the cruise, is on the effects of wind stress at the sea surface driving inertial oscillations, and so causing shear and mixing across the thermocline of seasonally-stratified shelf seas. The inertial shear is thought to interact with shear set up by the tidal currents, leading to pulses of mixing at the base of the thermocline. The project also aims to investigate the mixing in the context of supplying nutrients to the sub-surface layer of phytoplankton commonly seen within the shelf seas in summer, and to assess any possible shifts in the phytoplankton ecology as a response to the supply of nutrients. The cruise was planned around the use a free-fall turbulence profilers (Bangor University's VMP500 and NOC's VMP750) to measure rates of turbulent dissipation, moored instrumentation (ADCPs, temperature and chlorophyll loggers, McLane RAS water samplers, and meteorological sensors), long transects using Scanfish and the vessel hull-mounted ADCPs, and experiments on the water column biogeochemistry. The cruise was very successful. Initially calm weather allowed all of the moorings to be deployed easily, and then 2 strong wind events (generally northerly force 7) passed through the region allowing intense work with the turbulence profilers to make the key measurements of the vertical turbulent mixing. While both profilers eventually succumbed to damage as a result of recoveries during poor sea states, the data collected was of very high quality and clearly showed the spikes in thermocline mixing that we were looking for. The parallel biogeochemistry experiments showed a response in the nutrient distributions, in particular with the nitracline being raised within the thermocline as a result of the mixing and a reduction in primary production (i.e. wind events tend to be cloudy). |
