TLDR
In this paper, the spatial distribution and concentration of exopolysaccharides at 9 discrete sea ice sites, consisting of first year sea ice, and relates this information to physical (ice temperature, texture) and biogeochemical (oxygen stable isotopic composition of the ice, salinity, macronutrients, dissolved iron, particulate organic carbon, dissolved organic carbon and Chlorophyll a) variables.About:

The Organic Complexation of Iron in the Marine Environment: A Review
Martha Gledhill,Kristen N. Buck +1 more
TL;DR: Much work is still to be done in coupling voltammetry, mass spectrometry techniques, and process studies to better characterize the nature and cycling of Fe-binding ligands in the marine environment.

TL;DR: In this article, an important role of sea ice in the global biogeochemical cycles, promoted by active biological and chemical processes within the sea ice, fluid and gas exchanges at the sea-ice interface through an often permeable sea ice cover, and tight physical, biological, and chemical interactions between the Sea ice, the ocean and the atmosphere.

Sea Ice Ecosystems
TL;DR: The sea ice ecosystem provides food for a host of animals, with crustaceans being the most conspicuous, and ice algae likely contribute a shrinking fraction of the total amount of organic matter produced in polar waters.

Marine Biofilms: A Successful Microbial Strategy With Economic Implications
TL;DR: The costs to maritime transport, aquaculture, oil and gas industries, desalination plants and other industries are significant which has led to the development of various strategies to prevent biofilm formation and cleaning of infected surfaces.

Production of Metabolites as Bacterial Responses to the Marine Environment
TL;DR: The present work aims to provide a comprehensive review of the metabolites produced by marine bacteria in order to cope with intrusive environments, and to illustrate how such metabolites can be advantageously used in several relevant areas, from bioremediation to health and pharmaceutical sectors.

Colorimetric Method for Determination of Sugars and Related Substances
TL;DR: In this article, a method was developed to determine submicro amounts of sugars and related substances using a phenol-sulfuric acid reaction, which is useful for the determination of the composition of polysaccharides and their methyl derivatives.

TL;DR: It is demonstrated that iron supply controls phytoplankton growth and community composition during summer in these polar Southern Ocean waters, but the fate of algal carbon remains unknown and depends on the interplay between the processes controlling export, remineralisation and timescales of water mass subduction.
