Radiatively Active Gases from the North Atlantic RegiOn and Climate Change (RAGNARoCC)

This needs an alt tag!!!

Completed project

Project start: July 2013  |  Project end: June 2017
Funder: Natural Environment Research Council (NERC)
Principal Investigator: Dr Vassilis Kitidis
Other participants from PML: Dr Gennadi Lessin, Dr Peter Land, Ian Brown, Professor Philip Nightingale

The exchange of natural and man-made gases between the ocean and the atmosphere has profound implications for our environment. The speed of the gas transference, however, known as the kinetics of gas exchange, is currently poorly understood. This lack of knowledge limits the ability of numerical models to assess on-going global change and predict future climate. The RAGNARoCC project seeks to address the fundamental processes that control how fast gases are being exchanged and increase our understanding in this under-researched area.

The knowledge gained from this project can be utilised by environmental scientists and engineers who can apply RAGNARoCC’s measured rates of air-sea gas transfer to predict atmospheric pollutant deposition to, or toxin emission from, aqueous environments. Knowing how fast an exchange occurs is also critical for informing both the general public and policy makers, who play central roles in the preservation of the natural environment and the mitigation of climate change.

Within this project our scientists will investigate concentrations and fluxes of greenhouse gases in the North Atlantic by direct shipboard measurements and Earth Observation extrapolations over time and space.
