Ecosystem monitoring in coastal waters - ØKOKYST

The national monitoring program "Ecosystem monitoring in coastal waters - ØKOKYST" under the auspices of the Norwegian Environment Agency consists of several sub-programs that are divided into ecoregions. The program is part of the national basic monitoring of the environmental status of coastal waters and aims to monitor and map the environmental status in selected areas along the Norwegian coast.

Project period: 2021 - 2025

From Catchment to Coast (C2C)

How are northern ecosystems affected by climate change, and how do different ecosystems affect each other? This 5-year Fram Centre research program aims to provide critical new knowledge related to: (1) Cross-ecosystem climate change impacts; and (2) How to best integrate cross-ecosystem linkages into cohesive management approaches.

Project period: 2022 - 2026

Ocean Acidification Monitoring in Norwegian Waters

The purpose of the project is to monitor ocean acidification in Norwegian waters to provide an overview of the rate of acidification of Norwegian waters due to anthropogenic CO2 emissions.

Project period: 2021 - 2025
