On the nonlinear relationship between dissolved cadmium and phosphate in the modern global ocean: Could chronic iron limitation of phytoplankton growth cause the kink?
On the nonlinear relationship dissolved cadmium and phosphate the modern global ocean chronic iron limitation phytoplankton growth
2014/5/4
I report two vertical profiles of dissolved cadmium (Cd) and phosphate (PO4) from the Bering Sea: one from a high-nutrient, low-chlorophyll (HNLC) area, in which phytoplankton growth is limited by iro...
Different reactions of Southern Ocean phytoplankton size classes to iron fertilization
Different reactions Southern Ocean phytoplankton size classes iron fertilization
2014/5/4
During the European Iron Fertilisation Experiment (EIFEX), performed in the Southern Ocean, we investigated the reactions of different phytoplankton size classes to iron fertilization, applying measur...
Responses of estuarine and coastal marine phytoplankton to nitrogen and phosphorus enrichment
estuarine coastal marine phytoplankton
2014/4/30
A cross-ecosystem comparison of data obtained from 92 coastal zone ecosystems worldwide revealed a strong
positive response of marine phytoplankton biomass to nutrient enrichment that is highly consi...
Phytoplankton response to nutrient enrichment in an urbanized estuary: Apparent inhibition of primary production by overeutrophication
Phytoplankton response nutrient enrichment
2014/4/30
Phytoplankton response to nutrients was examined with a 26-yr database from the Delaware Estuary. Biomassnormalized primary production did not increase linearly with increasing nutrient concentrations...
Contribution of phytoplankton and bacterial cells to the measured alkalinity of seawater
phytoplankton bacterial cells
2014/4/23
We report the first direct measurements of the contribution of phytoplankton and bacterial cells to the measured
alkalinity of unfiltered seawater. Phytoplankton and bacterial cells suspe...
Individual foraging behaviors and population distributions of a planktonic predator aggregating to phytoplankton thin layers
Individual foraging behaviors population distributions
2014/4/23
Resource distributions in the ocean are heterogeneous in time and space. Theory predicts planktonic predators
may exploit these resource patches by modifying their movements in response to mechanical...
Carbon acquisition of marine phytoplankton: Effect of photoperiod length
Carbon acquisition of marine phytoplankton Effect of photoperiod length
2014/4/23
We investigated the carbon acquisition of three marine microalgae, Skeletonema costatum, Phaeocystis globosa,
and Emiliania huxleyi in response to different light regimes. Rates of photosynthetic O2

The biological and biogeochemical consequences of phosphate scavenging onto phytoplankton cell surfaces
The biological and biogeochemical consequences phosphate scavenging phytoplankton cell surfaces
2014/5/13
Phytoplankton carbon (C) and nitrogen (N) content is commonly normalized to phosphorus (P) quotas as Redfield C:N: P ratios. We examined how surface-bound P pools affect Redfield stoichiometry and P u...
Estimating the carbon flux through main phytoplankton groups in the northwestern Mediterranean
Estimating the carbon flux main phytoplankton groups northwestern Mediterranean
2014/5/13
We performed dilution experiments and primary production measurements in surface waters during a cruise in the northwestern Mediterranean Sea in June 2000 to quantify the carbon (C) flux through phyto...
Maximum photosynthetic efficiency of size-fractionated phytoplankton assessed by 14C uptake and fast repetition rate fluorometry
Maximum photosynthetic efficiency size-fractionated phytoplankton assessed 14C uptake fast repetition rate fluorometry
2014/5/13
Under high nutrient concentrations and sufficient light conditions, large phytoplankton may display higher photosynthetic efficiency than smaller cells. This is unexpected since smaller phytoplankton,...
Iron and zinc enrichments in the northeastern subarctic Pacific: Ligand production and zinc availability in response to phytoplankton growth
Iron and zinc enrichments northeastern subarctic Pacific Ligand production and zinc availability response to phytoplankton growth
2014/5/13
Iron- and zinc-enrichment experiments were carried out at Ocean Station Papa in the subarctic North Pacific. In iron-enriched treatments, phytoplankton chlorophyll a (Chl a) increased 20-fold (9.7 μg ...
