Seasonal cycles within the marginal ice zones in polar regions include large shifts in
temperature and salinity that strongly influence microbial abundance and physiology …

Arctic sea ice is experiencing a shorter growth season and an earlier ice melt onset. The
significance of spring microalgal blooms taking place prior to sea ice breakup is the subject …

The cellular exterior that a single-celled microorganism presents to its surroundings marks
its first line of defense against environmental pressures, from energy deprivation, shifts in …

Assemblages of the smallest of organisms–Bacteria, Archaea, and their viruses–can be
found throughout the brine network of sea ice, in surface features of the ice, and across the …

Antarctic pack ice is inhabited by a diverse and active microbial community reliant on
nutrients for growth. Seeking patterns and overlooked processes, we performed a large …

A paradox is commonly observed in productive sea ice in which an accumulation in the
macro-nutrients nitrate and phosphate coincides with an accumulation of autotrophic …

Sea-ice algae are an important source of primary production in polar regions, yet we have
limited understanding of their responses to the seasonal cycling of temperature and salinity …

Subzero hypersaline brines are liquid microbial habitats within otherwise frozen
environments, where concentrated dissolved salts prevent freezing. Such extreme …

Sea ice and its snow cover are critical for global processes including climate regulation and
biogeochemical cycles. Despite an increase in studies focused on snow microorganisms …

The salt-tolerant microorganisms also referred to as halotolerant including bacteria and
fungi have the ability to promote growth of plant in salty environment. Presence of certain …
