Carbon is a keystone element in global biogeochemical cycles. It plays a fundamental role
in biotic and abiotic processes in the ocean, which intertwine to mediate the chemistry and …

The warming of the Arctic Ocean impacts the dissolved organic matter (DOM) imports into
the Arctic region, which affects the local bacterial communities. This review addressed the …

The transformations of chemical constituents in subterranean estuaries (STEs) control the
delivery of nutrient loads from coastal aquifers to the ocean. It is important to determine the …

Abstract The subtropical South Pacific Gyre (SPG) encompasses the largest oligotrophic
region of the global ocean. In these remote waters dissolved organic matter (DOM) …

A clear divide typically exists between freshwater and marine microbial communities, with
transitional communities found in estuarine zones. The estuarine communities can derive …

Dissolved organic nitrogen (DON) represents the largest reservoir of fixed N in the surface
ocean and a significant portion accumulates in the deep sea, where it can persist for …

Dissolved organic matter (DOM) in marine waters is a complex mixture of compounds and
elements that contribute substantially to the global carbon cycle. The large reservoir of …

Dissolved free amino acids (DFAA) in seawater are a form of nitrogen (N) available for
marine microbes. In oligotrophic environments where N-containing nutrients are the limiting …

Abstract The River-Sea Transition Zone has a significant impact on marine ecosystems,
especially at present, due to increased anthropogenic pressure on rivers. The colloidal form …

Seepage from a carbon capture and storage site (CCS) under the seabed can lead to CO 2
enrichment of the surrounding seawater. This seepage may cause changes that alter the …
