UK Surface Ocean - Lower Atmosphere Study (UK SOLAS)

Project 16

3D simulation of dimethyl sulphide (DMS) in the North East Atlantic

Principal Investigator — Icarus Allen

Objectives

• To compare inputs of DMS to the marine boundary layer from the North West African upwelling system, and from aeolian deposition.
• To quantify the impact of the Mauretanian upwelling on DMS production and export to the atmosphere.
• To quantify the effects of radiative impacts, due to Saharan dust, on DMS production and export.
• To determine errors, and identify bias, in air-sea DMS exchange estimates.
• To establish an infrastructure for a 3D model of DMS in the North East Atlantic.

Activities

This project does not involve any independent fieldwork. It makes use of data arising from the UK SOLAS Deep Ocean Gas Exchange Experiment (DOGEE). Work focuses on the establishment of a 3D simulation of DMS in the marine boundary layer of the Cape Verde region.
