Greenland Ecosystem Monitoring – MarineBasis Zackenberg

Beautiful icebergs in Northeast Greenland

Greenland Ecosystem Monitoring (GEM) is an integrated monitoring and long-term research program on ecosystems and the impact of climate change on the Arctic. Since 1994 the program has established a coherent and integrated understanding of the functioning of terrestial, limnic and marine ecosystems in a highly variable climate. The program is based upon comprehensive, long-term interdisciplinary data collection carried out by Danish and Greenlandic monitoring and research institutions.

The MarineBasis program collects physical, chemical and biological data from the Greenland coastal zone, primarily at the two main field stations: Nuuk in low-arctic Southwest Greenland and Zackenberg in high-arctic Northeast Greenland. The MarineBasis program delivers baseline data that allows us to identify long-term trends in key parameters such as sea ice coverage, water temperature, salinity, CO2 uptake, nutrient concentrations, sinking flux, phytoplankton biomass and primary production, species composition of phytoplankton and zooplankton, macroalgal growth and the counting of marine mammals and seabirds (Nuuk). Data from the program is used by several international work groups under the Arctic Council such as CBMP, AMAP and CAFF. Work focuses on two fjord systems (Godthåbsfjord, SW Greenland and Young Sound, NE Greenland) both influenced by glaciers and/or melt rivers connected to the Greenland Ice Sheet.

MarineBasis Zackeberg is located in Young Sound (74°18′N, 20°18′W), a sill fjord with depths of up to 330 m. The long-term marine monitoring program was initiated in 2002, while marine studies have been conducted in the area since 1994. MarineBasis Zackenberg is funded by DANCEA, Danish Ministry of Energy, Utilities and Climate.
