Excretion of Dissolved Organic Phosphorus in Tropical Brackish Waters
Dissolved organic phosphorus (DOP) release was measured on natural populations of a brackish lagoon in Ivory Coast (West Africa). DOP mean excretion is 8% of net phosphorus absorption, and represents 1·7% h −1 of the biomass. Only 28% of biomass is involved in rapid uptake and excretion. Release of P is inversely proportional to the C p :N p ratio of

The seasonal melting of ice entombed cryoconite holes on McMurdo Dry Valley glaciers provides oases for life in the harsh environmental conditions of the polar desert where surface air temperatures only occasionally exceed 0°C during the Austral summer ...

Production, transformation, and degradation are the principal components of the cycling of dissolved organic matter (DOM) in marine systems. Heterotrophic Bacteria (and Archaea) play a large part in this cycling via enzymatic decomposition and ...

Biogeochemical cycling and phyto- and bacterioplankton communities in a large and shallow tropical lagoon (Términos Lagoon, Mexico) under 2009–2010 El Niño Modoki drought conditions [PDF]
The 2009–2010 period was marked by an episode of intense drought known as the El Niño Modoki event. Sampling of the Términos Lagoon (Mexico) was carried out in November 2009 in order to understand the influence of these particular environmental ...

Seasonal cycling of phosphorus in the Southern Bight of the North Sea [PDF]
We have investigated the seasonal cycle of nutrients, chlorophyll a, dissolved organic nitrogen (DON), and dissolved and particulate organic carbon (DOC and POC) for 10 stations in the Belgian coastal zone.

MESMO global model output for glacial simulations with dynamic C:N:P ratios [PDF]
Dataset: MESMO glacial CNPModel outputs archived have a complete suite of biogeochemical state variables in the 3D global ocean domain. They include temperature, salinity, nutrients (PO4, NO3, Fe, Si), carbon pools and their isotopes (DIC, DOC, POC, 13C ...

Salinization alters fluxes of bioreactive elements from stream ecosystems across land use [PDF]
There has been increased salinization of fresh water over decades due to the use of road salt deicers, wastewater discharges, saltwater intrusion, human-accelerated weathering, and groundwater irrigation.

Iron limitation of microbial phosphorus acquisition in the tropical North Atlantic
The influence iron exerts over the acquisition of dissolved organic phosphorus in regions of the oceans co-limited by nitrogen and phosphorus is poorly constrained.
