Spring plankton bloom hitches ride to sea's depths on ocean eddies
Spring plankton bloom sea's depths ocean eddies
2015/4/1
Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar "greening" event--a massive bloom of microscopic plants, or phytoplankton--unfolds each spring in the North ...
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...
Hydrologic and biotic influences on nitrate removal in a subtropical spring-fed river
Hydrologic biotic influences on nitrate removal a subtropical spring-fed river
2014/4/16
We use a long-term chemical and hydrologic record in combination with longitudinal sampling and highfrequency nitrate (NO{3) measurements from in situ sensors to describe temporal and spatial patterns...
Contrasting spring and summer phytoplankton dynamics in the nearshore Southern California Bight
spring summer phytoplankton dynamics nearshore Southern California Bight
2014/4/16
We analyzed a 9-yr record of ocean color data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS)together with a 4-yr record of satellite-derived sea surface temperature (SST) measurements to inv...
Marine Scientists Warn of "Moderately Large" Potential for Spring, Summer Red Tide Outbreak in Gulf of Maine（图）
Moderately Large Gulf of Maine Spring Summer
2009/4/30
The potential for an outbreak of the phenomenon called "red tide" is expected to be moderately large this spring and summer in the Gulf of Maine, according to researchers at the Woods Hole Oceanograph...
Diel carbon monoxide cycling in the upper Sargasso Sea near Bermuda at the onset of spring and in midsummer
Diel carbon monoxide cycling the upper Sargasso Sea Bermuda spring in midsummer
2014/4/21
Rapid bio-oxidation of carbon monoxide (CO), a photoproduct of dissolvedorganic matter, results in diel cycles reflecting photochemical–biogeochemical–physical interactions. These cycles were characte...
Resilience of North Sea phytoplankton spring bloom dynamics: An analysisof long-term data at Helgoland Roads
North Sea phytoplankton spring bloom Helgoland Roads
2014/4/18
Analyzing one of the most extensive long-term data series in the North Sea,the Helgoland Roads time series,we investigated the changes in the factors that potentially drive phytoplankton bloom dynamic...
Contrasting biogeochemistry of six trace metals during the rise and decay of a spring phytoplankton bloom in San Francisco Bay
biogeochemistry six trace metals during the rise decay of a spring phytoplankton bloom San Francisco Bay
2014/4/22
The spring 2003 phytoplankton bloom in South San Francisco Bay (South Bay) affected the cycling of Mn, Co, Zn, Ni, and Pb, but not Cu. We followed this diatom bloom for 2 months, capturing a peak in c...
Biogas (CO2, O2, dimethylsulfide) dynamics in spring Antarctic fast ice
Biogas dynamics in spring Antarctic fast ice
2014/4/22
We studied the temporal variations of CO2, O2, and dimethylsulfide (DMS) concentrations within three environments (sea-ice brine, platelet ice-like layer, and underlying water) in the coastal area of ...
Consequences of fish predation, migration, and juvenile ontogeny on zooplankton spring dynamics
Consequences of fish predation migration juvenile ontogeny zooplankton spring dynamics
2014/4/23
In order to disentangle if and when resource supply and adult and young-of-the-year (0+) fish predation affect zooplankton dynamics during spring, we monitored zooplankton during three consecutive yea...
Turbulent mixing and phytoplankton spring bloom development in a deep lake
Turbulent mixing phytoplankton spring bloom development a deep lake
2014/4/22
A one-dimensional (1-D) mechanistic phytoplankton model combined with a 1-D hydrodynamic model was applied to simulate phytoplankton growth during winter and spring in deep monomictic Upper Lake Const...
Gross photosynthesis and lake community metabolism during the spring phytoplankton bloom
Gross photosynthesis lake community metabolism spring phytoplankton bloom
2014/5/5
Daily productivity determinations of linear photosynthetic electron transfer and of net and gross inorganic CO2 uptake were determined in situ throughout a 6-week sampling period of the spring phytopl...
Spring bloom development, genetic variation, and population succession in the planktonic diatom Ditylum brightwellii
Spring bloom development genetic variation population succession planktonic diatom Ditylum brightwellii
2014/5/4
We determined spatial and temporal variation in abundance, distribution, and genetic composition of the planktonic marine diatom Ditylum brightwellii in 21 water samples collected between February and...
Tidal dynamics of dissolved and particulate matter and bacteria in a tidal flat ecosystem in spring and fall
Tidal dynamics of dissolved particulate matter bacteria in a tidal flat ecosystem spring and fall
2014/5/19
Tidal flat ecosystems are highly dynamic environments with tremendous short-term and long-term changes in physical, chemical, and biological properties. We measured salinity, temperature, oxygen, dry ...
