One-quarter of photosynthesis-derived carbon on Earth rapidly cycles through a set of short-
lived seawater metabolites that are generated from the activities of marine phytoplankton …

Antarctic landfast sea ice (fast ice) is stationary sea ice that is attached to the coast,
grounded icebergs, ice shelves, or other protrusions on the continental shelf. Fast ice forms …

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

Microalgae are important primary producers and form the basis for the marine food web. As
global climate changes, so do salinity levels that algae are exposed to. A metabolic …

Diatoms are a major phytoplankton group, playing a critical role in the biogeochemical
cycles of chemical elements such as carbon. They are one of the most abundant single …

The production and consumption of organic matter by marine organisms plays a central role
in the marine carbon cycle. Labile organic compounds (metabolites) are the major currency …

Small, biologically produced, organic molecules called metabolites play key roles in
microbial systems where they directly mediate exchanges of nutrients, energy, and …

The Arctic and Antarctic regions constitute 14% of the total biosphere. Although they differ in
their physiographic characteristics, both are strongly affected by snow and ice cover …

Phytoplankton transform inorganic carbon into thousands of biomolecules that represent an
important pool of fixed carbon, nitrogen, and sulfur in the surface ocean. Metabolite …

Diatoms are a crucial component in the study of aquatic ecosystems and ancient
environmental records. However, traditional methods for identifying diatoms, such as …
