Grazing and Zooplankton Production as Key Controls of Phytoplankton Production in the Open Ocean
Coast phytoplankton pigment waters physical oceanography
2015/8/17
Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
Simultaneous Imaging of Phytoplankton and Zooplankton Distributions
Phytoplankton Zooplankton Distributions
2015/8/6
Understanding the dynamics of the relationship between phytoplankton and higher trophic levels is necessary for understanding the transfers of matter and energy through planktonic food webs. There hav...
Intense Benthic Grazing on Phytoplankton in Coral Reefs Revealed Using the Control Volume Approach
Coral Reefs Revealed Control Volume Approach
2015/8/5
What is our international investment in oceanography, and how has it changed over the years? Two seemingly simple questions that have daunted our community repeatedly. The first of these two questions...
Over the past 100 years Scripps Institution of Oceanography has been a center for plankton research. Its reputation has waxed and waned depending largely on the scientists present, and their ability t...
Sixty Years of Sverdrup:A Retrospective of Progress in the Study of Phytoplankton Blooms
Sixty Years of Sverdrup Phytoplankton Blooms
2015/7/17
One of the most dramatic large-scale features in the ocean is the seasonal greening of the North Atlantic in spring and summer due to the accumulation of phytoplankton biomass in the surface layer. In...
REMOTE SENSING OF WATER COLOR: MODEL SENSITIVITY ANALYSIS AND ESTIMATION OF PHYTOPLANKTON SIZE FRACTIONS
Sensitivity analysis Phytoplankton size
2015/1/16
Phytoplankton size classes (pico-plankton, nano-plankton, and micro-plankton) provide information about pelagic ocean ecosystem structure, and their spatiotemporal variation is crucial in understandin...
The role of phytoplankton dynamics in the seasonal and interannual variability of carbon in the subpolar North Atlantic – a modeling study
phytoplankton dynamics seasonal interannual variability carbon subpolar North Atlantic modeling study
2014/12/10
We developed an ecosystem/biogeochemical model system, which includes multiple phytoplankton functional groups and carbon cycle dynamics, and applied it to investigate physical-biological interactions...
Comparative responses of two dominant Antarctic phytoplankton taxa to interactions between ocean acidification, warming, irradiance, and iron availability
ocean acidification warming irradiance
2014/11/28
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis
antarctica (a prymnesiophyte) and Fragilariopsis cylindrus(a diatom) to a clustered matrix of th...

Production of dissolved organic matter by phytoplankton and its uptake by heterotrophic prokaryotes in large tropical lakes
Production of dissolved organic matter by phytoplankton heterotrophic prokaryotes large tropical lakes
2014/7/10
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
Phytoplankton communities and care interactively affected by light, nutrients, and fish
Phytoplankton communities interactively
2014/4/4
We examined the separate and interactive effects of light, nutrients, and zooplanktivorous fish on
phytoplankton nutrient stoichiometry, taxonomic richness, community composition, and the association...
Episodic vertical nutrient fluxes and nearshore phytoplankton blooms in Southern California
Episodic vertical nutrient fluxes nearshore phytoplankton blooms Southern California
2014/4/2
Three distinct phytoplankton blooms lasting 4–9 d were observed in approximately 15-m water depth near Huntington Beach, California, between June and October of 2006. Each bloom was preceded by a vert...
Methionine synthase interreplacement in diatom cultures and communities: Implications for the persistence of B12 use by eukaryotic phytoplankton
Methionine synthase interreplacement diatom cultures communities: Implications persistence of B12 eukaryotic phytoplankton
2014/4/2
Three proteins related to vitamin B12 metabolism in diatoms were quantified via selected reaction monitoring mass spectrometry: B12-dependent and B12-independent methionine synthase (MetH, MetE) and a...
Spring phytoplankton communities shaped by interannual weather variability and dispersal limitation: Mechanisms of climate change effects on key coastal primary producers
Spring phytoplankton communities shaped interannual weather variability dispersal limitation Mechanisms of climate change effects key coastal primary producers
2014/4/2
Spring bloom composition in the Baltic Sea, a partially ice-covered brackish coastal waterbody, is shaped by winter–spring weather conditions affecting the relative dominance of diatoms and a heteroge...
Using stable nitrogen isotopes to evaluate the relative importance of external and internal nitrogen loadings on phytoplankton production in a shallow eutrophic lake (Lake Mikata, Japan)
a shallow eutrophic lake phytoplankton production
2014/4/2
The seasonal variability of the stable nitrogen isotope (d15N) in phytoplankton and dissolved inorganic
nitrogen (DIN) in the shallow, eutrophic Lake Mikata was examined to assess the relative import...
