Uncertainty and sensitivity in optode-based shelf-sea net community production estimates [PDF]

open access: yesBiogeosciences, 2016
Coastal seas represent one of the most valuable and vulnerable habitats on Earth. Understanding biological productivity in these dynamic regions is vital to understanding how they may influence and be affected by climate change.

Assessing net community production in a glaciated Alaskan fjord [PDF]

open access: yesBiogeosciences, 2015
The impact of deglaciation in Glacier Bay has been observed to seasonally influence the biogeochemistry of this marine system. The influence from surrounding glaciers, particularly tidewater glaciers, has the potential to affect the efficiency and ...

Linking patterns of net community production and marine microbial community structure in the western North Atlantic. [PDF]

open access: yesISME J, 2018
AbstractMarine net community production (NCP) tracks uptake of carbon by plankton communities and its potential transport to depth. Relationships between marine microbial community composition and NCP currently remain unclear despite their importance for assessing how different taxa impact carbon export.

Observation‐Based Estimate of Net Community Production in Antarctic Sea Ice

open access: yesGeophysical Research Letters
Antarctic sea ice is one of the largest biomes on Earth providing a critical habitat for ice algae. Measurements of primary production in Antarctic sea ice remain scarce and an observation‐based estimate of primary production has not been revisited in ...

Assessing Urban Community Gardens’ Impact on Net Primary Production using NDVI

open access: yesUrban Agriculture & Regional Food Systems, 2017
Community gardens are one form of urban agriculture–growing of food and non-food products for sale or consumption within urban and peri-urban areas.

Estimation of the net production of moss community at Langhovde, East Antarctica

open access: yesAntarctic Record, 1992
Field measurements of net photosynthesis and dark respiration (CO_2 exchange) of moss colonies were carried out at Langhovde, East Antarctica from 9 to 17 January 1988. Each colony growing at the Yukidori Valley, Langhovde was composed of Grimmia lawiana,

Daily variation in net primary production and net calcification in coral reef communities exposed to elevated pCO2 [PDF]

open access: yesBiogeosciences, 2017
The threat represented by ocean acidification (OA) for coral reefs has received considerable attention because of the sensitivity of calcifiers to changing seawater carbonate chemistry.

Artificial Upwelling in Singular and Recurring Mode: Consequences for Net Community Production and Metabolic Balance

open access: yesFrontiers in Marine Science, 2022
Artificial upwelling of nutrient-rich waters and the corresponding boost in primary productivity harbor the potential to enhance marine fishery yields and strengthen the biological pump for sequestration of atmospheric CO2. There is increasing urgency to

Research progress in calculating net community production of marine ecosystem by remote sensing

open access: yesFrontiers in Marine Science, 2023
Net community production (NCP) is defined as the difference between gross primary production (GPP) and total community respiration (R). NCP indicates the balance between the production and consumption of community organic carbon, therefore making it a ...

Net community production of dissolved organic carbon [PDF]

open access: yesGlobal Biogeochemical Cycles, 1998
Each year large amounts of carbon, with a residence time of months, accumulate in the surface layer of the ocean as semilabile dissolved organic carbon (DOC). This material is transported long distances, contributing to the interhemispheric transfer and deep ocean export of carbon.
