The material presented at the WGOH meetings each year is consolidated and published as the ICES Report on Ocean Climate (IROC).
With the IROC, the group analyses multiple time-series in a consistent way to give an overview of the state of the environment in the North Atlantic that includes: North Atlantic climate headlines, summary of upper ocean conditions, the North Atlantic atmosphere, and detailed area descriptions for the upper and lower oceans.
WGOH provides support to other expert groups requiring information on oceanic hydrography as well as expert knowledge and guidance to ICES Data Centre.
