Predicting plankton net community production in the Atlantic Ocean [PDF]
Deep Sea Research Part II: Topical Studies in Oceanography, 2009 13 pages, 7 figures, 2 tables.-- Available online Nov 17, 2008.-- Issue title: "The Atlantic Meridional Transect Progamme". We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

Oxygen photolysis in the Mauritanian upwelling: Implications for net community production [PDF]
Limnology and Oceanography, 2014 We carried out 16 photochemical experiments of filtered surface water in a custom‐built solar simulator and concomitant measurements of in vitro gross primary production (GPP) and respiration (R) in the Mauritanian upwelling during a Lagrangian study following three sulfur hexafluoride—labeled patches of upwelled water (P1 to P3).

Influence of coral and algal exudates on microbially mediated reef metabolism [PDF]
PeerJ, 2013 Benthic primary producers in tropical reef ecosystems can alter biogeochemical cycling and microbial processes in the surrounding seawater. In order to quantify these influences, we measured rates of photosynthesis, respiration, and dissolved organic ...

UV sensitivity of planktonic net community production in ocean surface waters [PDF]
Journal of Geophysical Research: Biogeosciences, 2014 AbstractThe net plankton community metabolism of oceanic surface waters is particularly important as it more directly affects the partial pressure of CO2 in surface waters and thus the air‐sea fluxes of CO2. Plankton communities in surface waters are exposed to high irradiance that includes significant ultraviolet blue (UVB, 280–315 nm) radiation.

An autonomous, in situ light‐dark bottle device for determining community respiration and net community production [PDF]
Limnology and Oceanography: Methods, 2018 AbstractWe describe a new, autonomous, incubation‐based instrument that is deployed in situ to determine rates of gross community respiration and net community production in marine and aquatic ecosystems. During deployments at a coastal pier and in the open ocean, the PHORCYS (PHOtosynthesis and Respiration Comparison‐Yielding System) captured ...

Ecosystem metabolism in a temporary Mediterranean marsh (Doñana National Park, SW Spain) [PDF]
Biogeosciences, 2011 The metabolic balance of the open waters supporting submerged macrophytes of the Doñana marsh (SW Spain) was investigated in spring, when community production is highest.

Plankton Community Metabolism in Western Australia: Estuarine, Coastal and Oceanic Surface Waters
Frontiers in Marine Science, 2021 Net community production (NCP) is a community level process informing on the balance between production and consumption, determining the role of plankton communities in carbon and nutrient balances fueling the marine food web.

Geophysical Research Letters, 2023 The Southern Ocean seasonal sea ice zone (SIZ) spring is characterized by sea ice retreat and the development of phytoplankton blooms. Until recently, assessing SIZ blooms and associated net community production (bNCP) has been limited by a lack of under‐

Ultraviolet radiation enhances Arctic net plankton community production [PDF]
Geophysical Research Letters, 2014 AbstractIn this study we report the response of net community production (NCP) of plankton communities in the Arctic surface waters exposure to natural ultraviolet radiation (UVR) conditions. A possible bias in previous measurements performed using borosilicate glass bottles (opaque to most UVR) can underestimate NCP.
