ICES Report on Ocean Climate 2018

Long time-series on ocean properties are rare for the sur­face ocean and even more uncommon for the deep ocean. The North Atlantic region is unique in having a relatively large number of locations where oceanographic data have been collected repeatedly for multiple years or decades; the longest records extend back more than a century. The IROC combines decades of ocean observations across the North Atlantic ICES region to describe the current status of sea temperature and salinity, and atmospheric conditions, as well as observed trends and recent vari­ability. The IROC production focuses the main efforts from ICES WGOH (González-Pola et.al. 2019) Section 1 synthesizes information from the longest time-series into an overview of changes across the ICES Area.
