5. FRagility of Arctic Goose habitat: Impacts of Land use, conservation and Elevated temperatures [FRAGILE]
The tundra ecosystem lies under threat. Increased numbers of breeding geese, caused by changes in European land use and bird protection measures, may damage the vulnerable tundra vegetation. Examples ...


6. plant and animal propagules inadvertently carried into the Antarctic [Aliens_Antarctic_Huiskes_IPY170_NL]
In the austral summer of 2007/2008, using the momentum of the International Polar Year (2007-2009), an international team of ecologists assessed propagule (e.g. seeds, spores, reproductive adult organisms) ...


7. Antarctic Coastal Ecology [ACE]
Objectives: ? To assess the structure and functioning of the Antarctic coastal ecosystem and the relationships between marine and terrestrial biota. ? To assess the origin of organic ...


8. Sources, Pathways and Sinks of Organic Matter in Antarctic Terrestrial Ecosystems (MATE) [MATE.NL]
Terrestrial, limnetic and coastal ecosystems in Antarctica are connected by transport (predominantly by melt water) of organic matter and minerals. Temperature increase (either ...


9. Arctic Ocean Dissolved Iron (Fe) Data from Flow Injection Analysis [Dissolved_Fe_Arctic_Klunder_IPY35_NL]
Dissolved iron was measured directly on board by Flow Injection Analysis (FIA) after De Jong et al. 1998 in a cleanroom container. In a continuous FIA system the acidified pH 1.8, filtered (0.2µm) ...


10. Development of tree ring like proxy on arctic shrubs Cassiope tetragona to reconstruct polar climate [Cassiope_Arctic_Climate_Proxy_Weijers_IPY59_NL]
Annual stem length, annual number of leaves, annual average leaf length, annual total leaf length and leaf lifespan. All of Cassiope tetragona. These parameters were measured at three sites: Ny-?lesund ...


11. Southern Ocean Dissolved Iron (Fe) Data from Flow Injection Analysis [Dissolved_Fe_Antarctic_Klunder_IPY35_NL]
Dissolved iron was measured directly on board by Flow Injection Analysis (FIA) after De Jong et al. 1998 in a cleanroom container. In a continuous FIA system the acidified pH 1.8, filtered (0.2µm) ...
