The role of glacier mice in the invertebrate colonisation of glacial surfaces: the moss balls of the Falljökull, Iceland [PDF]

, 2012
Glacier surfaces have a surprisingly complex ecology. Cryoconite holes contain diverse invertebrate communities while other invertebrates, such as Collembola often graze on algae and windblown dead organic on the glacier surface.

Methods of Iceberg Towing [PDF]

TransNav, 2012
Mathematical models of iceberg towing by a ship connected to the iceberg by mooring lines are considered. Governing equations describing the towing and the tension of mooring lines in two different schemes of the towing are formulated.

Morphological characterization of Recherchefjorden (Bellsund, Svalbard) using marine geomorphometry [PDF]

Polish Polar Research, 2018
Geomorphological research based on geomorphological mapping seeks to identify the origins and age of forms as well as to describe the process that created or transformed a particular form.

Ecological and evolutionary consequences of ploidy-driven trait variation: insights from Saxifraga oppositifolia L.

Arctic Science
The ecological and evolutionary consequences of ploidy-driven trait variation, particularly for autopolyploids, remain poorly understood. Saxifraga oppositifolia L.

Circulation and exchange in a broad Arctic fjord using glider-based observations

Polar Research, 2018
In recent years, Svalbard fjords have experienced a substantial reduction in winter sea-ice extent. This has been linked to changes in wind stress patterns over Fram Strait and an increased transport of warm Atlantic Water into the fjords.

Distinct or similar? Soft bottom polychaete diversity in Arctic and Antarctic glacial fjords [PDF]

, 2014
The main aim of this study was to compare the polychaete communities in two similar polar areas: an Arctic fjord, Hornsund (Svalbard) and an Antarctic fjord, Ezcurra Inlet (South Shetlands).

Temporal shifts in kelp forest structure and distribution largely reflect recent ocean warming trends

Ecography, EarlyView.
Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...

The influence of local winds on wind power characteristics in a High Arctic valley [PDF]

Wind Energy Science
Wind power in the High Arctic is under-developed, and understanding of the local wind conditions is needed. Therefore, the average wind characteristics in the Svalbard valley Adventdalen are investigated using primarily observations from wind profilers ...

Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters [PDF]

, 2002
The diversity of lichens, especially crustose species, in continental Antarctica is still poorly known. To overcome difficulties with the morphology based species delimitations in these groups, we employed molecular data (nuclear ITS and mitochondrial ...

Sampling Biases in Daily Average Temperatures From Greenland Climate Records

International Journal of Climatology, EarlyView.
Biases are introduced in the calculation of daily average temperatures due to uneven sampling times for the investigated weather station network in Greenland. The figure shows the network, an example of a daily temperature cycle with daily averages based on all or only two observations and an overview of how the number of observations per day changes ...
