Modelling carbon overconsumption and the formation of extracellular particulate organic carbon
During phytoplankton growth a fraction of dissolved inorganic carbon (DIC) assimilated by phytoplankton is exuded in the form of dissolved organic carbon (DOC), which can be transformed into extracellular particulate organic carbon (POC). A major fraction of extracellular POC is associated with carbon of transparent exopolymer particles (TEP; carbon content = TEPC) that form from dissolved poly...
متن کاملTrace Metals, Organic Carbon, and Inorganic Nutrients in Surface Waters of the Long Island Sound: Sources, Cycling and Effects
This study provides an extensive dataset of dissolved trace metals (silver, cadmium, copper, nickel, lead, iron, and zinc), inorganic (ammonia, nitrate, phosphate and silicates), and organic (urea, dissolved organic nitrogen, carbon and phosphorous, as well as particulate carbon and nitrogen) constituents during high and low riverine flow conditions in surface waters of the Long Island Sound. A...
متن کاملImpact of a river flash flood on microbial carbon and nitrogen production in a Mediterranean Lagoon (Thau Lagoon, France)
Over half of the total nitrogen, phosphorus, silicate and dissolved organic carbon (DOC) loading was discharged from the Vène River into the Thau Lagoon waters within the first five days of what was considered to be the autumn flash flood period. Such loads represented about 8% and 3% of the yearly averaged total nitrogen and phosphorus load in Thau Lagoon, respectively. Although this event aff...
متن کاملDistribution and partitioning of nitrogen and phosphorus in a fringing reef lagoon of Ishigaki Island, northwestern Pacific
Concentration of dissolved and particulate carbon (C), nitrogen (N), and phosphorus (P) were measured daily and seasonally in the water column of a coral reef lagoon at Ishigaki Island. Concentrations of dissolved inorganic N and P (DIN, DIP), dissolved organic C and N (DOC, DON), particulate organic C, and particulate N and P (POC, PN, PP) were usually higher in the lagoon than at offshore sta...
متن کاملCycling of colloidal organic carbon and nitrogen during an estuarine phytoplankton bloom
To establish the influence of phytoplankton blooms on the cycling of dissolved and particulate species of organic carbon and nitrogen, we conducted a field study during a series of blooms in a coastal embayment on Shelter Island, NY. Using cross-flow filtration, we collected highand low-molecular-weight (HMW and LMW) dissolved organic matter (DOM), along with particulate organic matter (POM). T...
