History of WG 38

Working Group 38 was formed in 2008 because of growing concern about the impact of atmospheric deposition of both natural and anthropogenic substances on ocean chemistry, biology, and biogeochemistry as well as climate.  It has held meetings at the University of Arizona, Tucson, AZ, in 2008, at IMO in London in 2010, in Malta in 2011, and at the University of East Anglia, Norwich, UK in 2013. Sponsors of those WG 38 efforts have included WMO, IMO, SCOR, SIDA, the European Commission Joint Research Centre, the University of Arizona, the International Environment Institute at the University of Malta, and the University of East Anglia, and the US National Science Foundation.  Following the initial terms of reference, five scientific papers have been published in the peer-reviewed scientific literature.

More Recent Activities of WG 38

From 27 February to March 2 two workshops took place at the University of East Anglia (UEA), Norwich, United Kingdom under the auspices of GESAMP Working Group 38 and sponsored by WMO, NSF, SCOR, SOLAS and UEA. These workshops focussed on the changes in the acid/base balance of the atmosphere and ocean, and their impacts on air-sea exchange.


Workshop One focussed on Changing Atmospheric Acidity and its Impacts on the Oceanic Solubility of Nutrients.

Workshop Two foucsed on The Impact of Ocean Acidification on Fluxes of Non-CO2 Climate-Active Species.
