Greenland Ecosystem Monitoring

Greenland Ecosystem Monitoring (GEM) is an integrated monitoring and long-term research programme on ecosystems and climate change effects and feedbacks in the Arctic. Since 1995 the programme has established a coherent and integrated understanding of the functioning of ecosystems in a highly variable climate, which is based upon a comprehensive, long-term inter-disciplinary data collection carried out by Danish and Greenlandic monitoring and research institutions. 

The GEM Programme put around 75 scientists in the field annually to collect data on ecosystem and climate change in Greenland. The data base currently covers data from monitoring programmes from Zackenberg (1995-), Kobbefjord at Nuuk (2007-) and Disko (2017-). The well over 1000 parameters are freely available via the GEM Database and used by GEM participants and external scientists to produce scientific papers, scientific assessments, advisory reports, etc.

Young Sound: the least productive fjord in Greenland

The title of this article recently published in the GEM Annual Report cards 2019 might seem bold, however, Johnna Holding, Mikael Sejr and colleagues have been studying primary production by phytoplankton in fjords around Greenland for the past several years. They find that, indeed, the site of the MarineBasis monitoring programme in Young Sound…

GEM Scientist Of The Month - August

This Scientist Of The Month features Efrén López-Blanco. Coming from Spain he never imagined to end up so tightly bonded to the Arctic. He is an active GEM database user since 2014, and is soon starting a new position in Greenland, and just had a paper published with data from the GEM sites in Kobbefjord and Zackenberg.
