Light and nutrient control of photosynthesis in natural phytoplankton populations from the Chukchi and Beaufort seas, Arctic Ocean
Light nutrient control of photosynthesis
2014/4/2
During the 2010–2011 ‘Impacts of Climate Change on the EcoSystems and Chemistry of the Arctic Pacific
Environment’ project, we measured photosynthetic parameters in natural Arctic phytoplankton assem...

In situ diel cycles of photosynthesis and calcification in hermatypic corals
In situ diel cycles photosynthesis calcification hermatypic corals
2014/4/17
Diel cycles of photosynthesis, respiration, and calcification were studied in situ on two hermatypic corals,Acropora eurystomaandFavia favus, using a submerged respirometer deployed at 5-m depth in th...
Diffusive boundary layers do not limit the photosynthesis of the aquatic macrophyte Vallisneria americanaat moderate flows and saturating light levels
Diffusive boundary layers do not limit the photosynthesis the aquatic macrophyte Vallisneria americana moderate flows saturating light levels
2014/4/17
Hydrodynamic models of mass transport assume that diffusive processes next to the surface limit transport and that there are no biological and chemical processes that control the supply and demand of ...

Phytoplankton distribution photosynthesis dynamics the Chubut River estuary throughout tidal cycles
2014/4/16
The aim of this study was to determine the effects of the tidal dynamics and physical forcing on phytoplankton distribution and photosynthesis dynamics in the Chubut River estuary, Argentina. Physical...

2014/4/17
Respiration and photosynthesis of the planktonic foraminifera Globigerinoides ruber, Orbulina universa, and
Globigerinella siphonifera and their symbiotic algae were calculated from measured dissolve...
Nutrient limitation of picophytoplankton photosynthesis and growth in the tropical North Atlantic
picophytoplankton photosynthesis growth in the tropical North Atlantic
2014/4/21
Identification of the proximal nutrient limiting primary production is a necessary first step toward evaluating
the physiological state of phytoplankton communities and the biogeochemical constraints...
A model of photosynthesis and photo-protection based on reaction center damage and repair
A model of photosynthesis photo-protection
2014/4/21
Phytoplankton photosynthesis under the rapidly fluctuating irradiance which results from turbulent mixing
through the vertical light gradient is poorly understood. Ship-based measurements often apply...

wave effects photosynthesis Experiments theory modeling
2014/4/21
Using field experiments and mathematical models, we tested whether internal waves enhance photosynthesis as they move phytoplankton through a nonlinear light field in situations where photosynthesis i...
Acclimation to elevated carbon dioxide and ultraviolet radiation in the diatom Thalassiosira pseudonana: Effects on growth, photosynthesis, and spectral sensitivity of photoinhibition

Temporal vertical variability photosynthesis North Pacific Subtropical Gyre
2014/4/18
In situ fast-repetition-rate fluorometric (FRRF) surveys were conducted in the North Pacific Subtropical Gyre(NPSG) at Station ALOHA (Sta. ALOHA, 22u459N, 158u009W), from September 2002 to December 20...
Scaling of phytoplankton photosynthesis and cell size in the ocean
phytoplankton photosynthesis cell size
2014/4/22
We have determined the scaling relationship between photosynthesis rate and cell size in natural
phytoplankton assemblages of contrasting marine environments. We found that phytoplankton photosynthes...
Effect of varying calcium concentrations and light intensities on calcification and photosynthesis in Emiliania huxleyi

2014/4/22
Various protective and metabolic functions for coccolithophore calcification have been proposed such as
providing a means to supply CO2
for photosynthesis. It has also been speculated that calcifica...
