A new dark ice albedo threshold and its applications
Dark ice (low albedo) areas are hot spots for investigating biological and abiotic darkening processes and their impact on the melt rate of the Greenland Ice Sheet. This study introduces a quantitative method for determining albedo thresholds to delineate areas of dark ice, which detects abrupt changes in the mean and linear trends in time series of weather station albedo measurements in documented dark ice areas. Four different stages of albedo …
Net heterotrophy in High Arctic first-year and multi-year spring sea ice
The net productivity of sea ice is determined by the physical and geochemical characteristics of the ice–ocean system and the activity of organisms inhabiting the ice. Differences in habitat suitability between first-year and multi-year sea ice can affect the ice algal community composition and acclimation state, introducing considerable variability to primary production within each ice type. In this study, we characterized the biogeochemical var…
Monitoring a changing Arctic
Sea ice continues to decline across many regions of the Arctic, with remaining ice becoming increasingly younger and more dynamic. These changes alter the habitats of microbial life that live within the sea ice, which support healthy functioning of the marine ecosystem and provision of resources for human-consumption, in addition to influencing biogeochemical cycles (e.g. air–sea CO 2 exchange). With the susceptibility of sea ice ecosystems to cl…
Cryospheric ecosystems
The fourteen letters that contributed to this focus issue on cryospheric ecosytems provide an excellent basis for considering the state of the science following a marked increase in research attention since the new millennium. Research letters from the focus issue provide significant insights into the biogeochemical and biological processes associated with snow, glacier ice and glacial sediments. This has been achieved via a significant, empirica…
Environmental factors influencing diatom communities in Antarctic cryoconite holes
Cryoconite holes are ice-bound habitats that can act as refuges for aquatic and terrestrial microorganisms on glacier surfaces. In the McMurdo Dry Valleys of Antarctica, these holes are often capped by an ice lid that prevents the exchange of material and gases with the surrounding atmosphere and aquatic environment. Diatoms have been documented in cryoconite holes, and recent findings suggest that these habitats may harbour a distinctive diatom …
Viral impacts on bacterial communities in Arctic cryoconite
The surfaces of glaciers are extreme ecosystems dominated by microbial communities. Viruses are found in abundance here, with a high frequency of bacteria displaying visible virus infection. In this study, viral and bacterial production was measured in Arctic cryoconite holes to address the control that viruses play in these highly truncated ecosystems. Mean bacterial carbon production in the sediments of cryoconite holes was found to be 57.8 +/-…
The Mcmurdo Dry Valleys Long‐Term Ecological Rsearch Program
The McMurdo Dry Valleys Long‐Term Ecological Research (MCM‐LTER) site represents the highest‐latitude location of the 24 LTER sites supported by the U.S. National Science Foundation. Although the perennial ice‐covered lakes in the dry valleys have been investigated since IGY, detailed, ecosystem‐based studies have been conducted on these lakes since 1993 by LTER investigators. A review of recent findings on the biogeochemistry and food‐ chain dyn…
