UK Surface Ocean - Lower Atmosphere Study (UK SOLAS)

Project 12

The impact of coastal upwellings on air-sea exchange of climatically important gases - ICON

Principal Investigator — Carol Robinson, Plymouth Marine Laboratory (PML).

Objectives

• To determine the role of upwelling on the supply, loss and air-sea exchange of trace and biogenic gases
• To determine the photochemical and biological fate of upwelled and recently produced dissolved organic matter
• To assess the role of this organic matter in air-sea exchange of climatically important trace gases

Activities

The project is centred around a research cruise in the upwelling region off Northwest Africa (D338). Sampling and daily incubation experiments were conducted to assess

• Primary production
• pCO2 and tracer measurements
• A suite of physical, biogeochemical and bio-optical parameters
