Kilauea lava fuels phytoplankton bloom off Hawaii Island（图）
Kilauea lava fuels phytoplankton bloom Hawaii Island
2019/10/18
The 2018 Kilauea volcano eruption injected millions of cubic feet of molten lava into nutrient-poor waters off the Big Island of Hawaii. The lava-impacted seawater contained high concentrations of nut...
Deep-ocean vents fuel massive phytoplankton blooms（图）
Deep-ocean vents fuel phytoplankton blooms
2019/10/28
Researchers at Stanford University have found an aquatic highway that releases nutrients from within the Earth and ferries them up to surface waters off the coast of Antarctica. There the nutrients st...
Sensitivity of Antarctic phytoplankton species to ocean acidification: Growth, carbon acquisition, and species interaction
Growth carbon acquisition species interaction
2014/4/2
Despite the fact that ocean acidification is considered to be especially pronounced in the Southern Ocean, little
is known about CO2
-dependent physiological processes and the interactions of Antarc...
Distribution and chromatic adaptation of phytoplankton within a shelf sea thermocline
Distribution chromatic adaptation phytoplankton shelf sea thermocline
2014/4/18
Observations of vertical gradients in phytoplankton community structure were made through the water column of the seasonally stratified Celtic Sea, including within the thermocline. A deep chlorophyll...
Observations of turbulent mixing in a phytoplankton thin layer: Implications for formation, maintenance, and breakdown
Observations of turbulent mixing formation maintenance
2014/4/18
Coincident measurements of chlorophyll a (Chl a) and temperature microstructure from Monterey Bay,
California, U.S.A., are used to investigate the dynamics of a phytoplankton thin layer in the contex...
Role of phytoplankton in mercury cycling in the San Francisco Bay estuary
Role of phytoplankton he San Francisco Bay estuary
2014/4/17
To study the role of phytoplankton in mercury cycling, we measured methylmercury (MeHg) and total
mercury (HgT) in surface waters during the spring 2003 phytoplankton bloom in San Francisco Bay. Cond...
To sink or to be lysed? Contrasting fate of two large phytoplankton species in Lake Biwa
lysed phytoplankton species
2014/5/5
We estimated the contributions of sedimentation and cell lysis to the loss of two large phytoplankton species
(Fragilaria crotonensis and Staurastrum dorsidentiferum) in Lake Biwa. Major loss process...
Phytoplankton trapped within seagrass (Posidonia oceanica) sediments are a nitrogen source: An in situ isotope labeling experiment
Phytoplankton trapped within seagrass sediments nitrogen source: An in situ isotope labeling experiment
2014/5/4
We examined the retention of nitrogen associated with sedimented planktonic material trapped within a Mediterranean seagrass (Posidonia oceanica) meadow with the use of 15N-enriched algal material inj...
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...
Wind-induced modulation of seasonal phytoplankton blooms in the North Atlantic derived from satellite observations
seasonal phytoplankton blooms satellite observations
2014/5/13
We examined the interannual variability in the timing and magnitude of seasonal phytoplankton blooms in the
North Atlantic (708N–108N, 908W–108E) in relation to variability in wind forcing during the...
Phytoplankton nutrient competition under dynamic light regimes
Phytoplankton nutrient competition dynamic light regimes
2014/5/16
Many physiological processes in phytoplankton, including nutrient uptake, vary on a number of temporal scales.
Experiments show that the daily cycle in irradiance affects nutrient uptake rates. We us...
Relationship of nitrogen isotope fractionation to phytoplankton size and iron availability during the Southern Ocean Iron RElease Experiment (SOIREE)
nitrogen isotope fractionation phytoplankton size iron availability the Southern Ocean Iron RElease
2014/5/20
The 15N composition of sediments has been used as a proxy for nitrate utilization in surface waters to assess the role of Southern Ocean export production in glacial/interglacial changes in atmospheri...
Algal games: The vertical distribution of phytoplankton in poorly mixed water columns
phytoplankton poorly mixed water columns
2014/5/30
Phytoplankton often face the dilemma of living in contrasting gradients of two essential resources: light that is
supplied from above and nutrients that are often supplied from below. In poorly mixed...
