Interactions between microorganisms and algae during bloom events significantly impacts
their physiology, alters ambient chemistry, and shapes ecosystem diversity. The potential …

Rising temperatures and changing winds drive the expansion of the highly productive
polynyas (open water areas surrounded by sea ice) abutting the Antarctic continent …

In the aquatic environment, microorganisms are predominantly organized as biofilms.
Biofilms are formed by the aggregation of microbial cells and are surrounded by a matrix of …

The marine ecosystem along the Western Antarctic Peninsula undergoes a dramatic
seasonal transition every spring, from almost total darkness to almost continuous sunlight …

Antarctica polynyas support intense phytoplankton blooms, impacting their environment by a
substantial depletion of inorganic carbon and nutrients. These blooms are dominated by the …

Bacterial consumption of dissolved organic matter (DOM) drives much of the movement of
carbon through the oceanic food web and the global carbon cycle. Understanding complex …

Nitrite-oxidizing bacteria (NOB) are chemolithoautotrophs that catalyze the oxidation of
nitrite to nitrate, which is the second step of aerobic nitrification. In marine ecosystems …

Marine sediments are a microbial biosphere with an unknown physiology, and the
sediments harbor numerous distinct phylogenetic lineages of Bacteria and Archaea that are …

Abstract In the Southern Ocean, natural iron fertilization in the wake of islands leads to
annually occurring spring phytoplankton blooms associated with enhanced heterotrophic …

Nitrification, a central process in the marine nitrogen cycle, produces regenerated nitrate in
the euphotic zone and emits N2O, a potent greenhouse gas as a by-product. The regulatory …
