Microbial ecology of the cryosphere: sea ice and glacial habitats
The Earth's cryosphere comprises those regions that are cold enough for water to turn into
ice. Recent findings show that the icy realms of polar oceans, glaciers and ice sheets are …

The role of bacterial extracellular polymeric substances in geomicrobiology
J Tourney, BT Ngwenya - Chemical Geology, 2014 - Elsevier
The last two decades have seen geomicrobiology evolve into a broad field encompassing a
wide range of environmentally significant processes such as proton and metal adsorption …

Sea ice microorganisms: Environmental constraints and extracellular responses
Inherent to sea ice, like other high latitude environments, is the strong seasonality driven by
changes in insolation throughout the year. Sea-ice organisms are exposed to shifting …

Optical and molecular characterization of dissolved organic matter (DOM) in the Arctic ice core and the underlying seawater (Cambridge Bay, Canada): Implication for …
Sea ice contains a large amount of dissolved organic matter (DOM), which can be released
into the ocean once it melts. In this study, Arctic sea ice DOM was characterized for its optical …

Methods for biogeochemical studies of sea ice: The state of the art, caveats, and recommendations
Over the past two decades, with recognition that the ocean's sea-ice cover is neither
insensitive to climate change nor a barrier to light and matter, research in sea-ice …

Sea ice, extremophiles and life on extra-terrestrial ocean worlds
The primary aim of this review is to highlight that sea-ice microbes would be capable of
occupying ice-associated biological niches on Europa and Enceladus. These moons are …
