Seasonal variability of the warm Atlantic Water layer in the vicinity of the Greenland shelf break [PDF]

, 2014
The warmest water reaching the east and west coast of Greenland is found between 200?m and 600?m. Whilst important for melting Greenland's outlet glaciers, limited winter observations of this layer prohibit determination of its seasonality.

Environmental controls of autotrophic biofilm biomass and community composition in subarctic lakes and streams in Greenland

Limnology and Oceanography, EarlyView.
Abstract Photosynthetic biofilms are key components of Arctic freshwater ecosystems, supporting primary production and forming the base of aquatic food webs. While several environmental factors regulating biofilms are known, their relative importance and connection to catchment characteristics across different Arctic ecosystems remain unclear.

Parametric CubeSat flight simulation architecture [PDF]

, 2013
This paper presents the architecture of a system of models that provides realistic simulation of the dynamic, in-orbit behaviour of a CubeSat. Time-dependent relationships between sub-systems and between the satellite and external nodes (ground stations ...

Land influence decouples benthic nutrient fluxes on the Siberian Arctic Ocean shelves

Limnology and Oceanography Letters, EarlyView.
Abstract Land permafrost thaw transfers increasing amounts of organic matter and nutrients to the Arctic Ocean. These nutrients could stimulate primary production directly, or indirectly following remineralization in sediments. Projections of this effect are limited by scarce observations and poor understanding of the underlying controls.

Recent changes in the surface salinity of the North Atlantic subpolar gyre [PDF]

, 2002
Sea surface salinity (SSS) was measured since 1896 along 60°N between Greenland and the North Sea and since 1993 between Iceland and Newfoundland. Along 60°N away from the shelves, and north of 53°N, the amplitude of the seasonal cycle is comparable to ...

Glacial meltwater drives high CH4 supersaturation in Maxwell Bay, King George Island (Southern Ocean)

Limnology and Oceanography Letters, EarlyView.
Abstract Coastal waters exhibit the highest and most dynamic dissolved CH4 concentrations in marine environments, but significant knowledge gaps on the distribution and emissions, particularly in the Southern Ocean, still exist. We quantified dissolved CH4 concentrations and sea–air fluxes in the coastal waters of Maxwell Bay, King George Island ...

Personal experiences of living with sucrose intolerance and attitudes towards genetic research in Greenland - a user study

International Journal of Circumpolar Health
There is high prevalence of the genetic SI variant c.273_274delAG in the sucrase-isomaltase-encoding gene in Greenland, resulting in congenital sucrase-isomaltase deficiency and thereby an inability to digest sucrose, the most common dietary sugar. There
