Monitoring ocean acidification in Norwegian seas in 2019

This is the annual report from 2019 based on the program: ‘Monitoring ocean acidification in Norwegian waters’ and ‘Monitoring of ocean acidification in the coastal zone’ funded by the Norwegian Environment Agency. The measurements are performed by the Institute of Marine Research (IMR), Norwegian Institute for Water Research (NIVA), Norwegian Research Centre (NORCE) and the Univsersity of Bergen (UiB).

The measurements cover the North Sea/Skagerrak, the Norwegian Sea, and the seasonally ice-covered Barents Sea. In 2019, the program “Monitoring of ocean acidification in the coastal zone” included five fixed water column station, four lines with underway surface measurements (discrete and/or continuous) and seven cold-water coral reefs. This report presents and discusses some time series data for the period 2011-2019.
