A global ocean dissolved organic phosphorus concentration database (DOPv2021) [PDF]

Scientific Data, 2022
Dissolved organic phosphorus (DOP) concentration distributions in the global surface ocean inform our understanding of marine biogeochemical processes such as nitrogen fixation and primary production. The spatial distribution of DOP concentrations in the

Bioavailability of Dissolved Organic Phosphorus in Temperate Lakes [PDF]

Frontiers in Environmental Science, 2018
Freshwater aquatic systems are biogeochemical hotspots, with heterotrophic bacteria rapidly cycling the compounds that pass through them. P is a key nutrient that controls primary production in many freshwater ecosystems and is important for ...

Sargasso Sea phosphorus biogeochemistry: an important role for dissolved organic phosphorus (DOP) [PDF]

Biogeosciences, 2010
Inorganic phosphorus (SRP) concentrations in the subtropical North Atlantic are some of the lowest in the global ocean and have been hypothesized to constrain primary production.

Origin of dissolved organic carbon under phosphorus-limited coastal-bay conditions revealed by fluorescent dissolved organic matter

Frontiers in Marine Science, 2022
To determine the origins of dissolved organic carbon (DOC) in a bay of volcanic Jeju Island, where the discharge of fresh groundwater (FGW) is dominant, we measured fluorescent dissolved organic matter (FDOM) and implemented a parallel factor analysis ...

Sorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil [PDF]

Journal of Environmental Quality, 2007
Molibility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from oils to surface waters. To study the sorption an mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM ...

Bioavailable dissolved organic phosphorus and phosphorus use by heterotrophic bacteria [PDF]

Aquatic Biology, 2007
Dissolved organic phosphorus (DOP) concentrations were measured in surface water at 3 stations in the central Baltic Sea from May to July 2005. The amount of bioavailable DOP (BAP) was estimated in time course experiments using 0.8 µm filtered seawater and carbon plus nitrogen addi- tions with the aim of verifying results obtained in 2004.

The composition of organic phosphorus in a river during the springtime irrigation period

Journal of Hydrology: Regional Studies, 2022
Study region: The study region was the Sakura River, a tributary of Lake Kasumigaura, Japan. Study focus: We asked whether particulate organic phosphorus (POP) contributed to the P cycle in rivers. Previous studies have focused on the interaction between
