Journal ArticleDOI
Antarctic Sea Ice--a Habitat for Extremophiles
TL;DR: Apart from their ecological importance, the bacterial and algae species found in sea ice have become the focus for novel biotechnology, as well as being considered proxies for possible life forms on ice-covered extraterrestrial bodies.
Book
Sea ice : an introduction to its physics, chemistry, biology, and geology
TL;DR: This book discusses the importance of Sea Ice, a Critical Habitat for Polar Marine Mammals and Birds, and from the Microscopic to the Macroscopic, to the Regional Scale: Growth, Microstructure and Properties of Sea ice.
Journal ArticleDOI
Large scale importance of sea ice biology in the Southern Ocean
Kevin R. Arrigo,David N. Thomas +1 more
TL;DR: An analysis of how the balance between sea ice and pelagic production might change under a warming scenario indicates that when current levels of primary production and changes in the areas of sea ice habitats are taken into account, the expected 25% loss ofSea ice over the next century would increase primary production in the Southern Ocean by approximately 10%, resulting in a slight negative feedback on climate warming.
Journal ArticleDOI
Characteristics of dissolved organic matter in Baltic coastal sea ice: allochthonous or autochthonous origins?
Colin A. Stedmon,David N. Thomas,Mats A. Granskog,Hermanni Kaartokallio,Stathys Papadimitriou,Harri Kuosa +5 more
TL;DR: The origin of dissolved organic matter (DOM) within sea ice in coastal waters of the Baltic Sea was investigated using parallel factor (PARAFAC) analysis of DOM fluorescence, indicating that the majority of the organic carbon and nitrogen in Baltic Sea ice is bound in terrestrial humic material trapped within the ice.
Journal ArticleDOI
Calcium carbonate as ikaite crystals in Antarctic sea ice
Gerhard Dieckmann,Gernot Nehrke,Gernot Nehrke,Stathys Papadimitriou,Jörg Göttlicher,Ralph Steininger,Hilary Kennedy,Dieter Wolf-Gladrow,David N. Thomas +8 more
TL;DR: The discovery of CaCO3·6H2O crystals in natural sea ice provides the necessary evidence for the evaluation of previous assumptions and lays the foundation for further studies to help elucidate the role of ikaite in the carbon cycle of seasonally sea ice-covered regions.
