RAPID: Research on Automated Plankton Identification
Automated Plankton Identification Plankton
2015/7/22
When Victor Hensen deployed the first true plankton net in 1887, he and his colleagues were attempting to answer three fundamental questions: What planktonic organisms are present in the ocean? How ma...
New Cultivation Strategies Bring More Microbial Plankton Species into the Laboratory
Microbial Plankton Species Laboratory
2015/7/22
It is difficult to describe the properties of a microorganism without first cultivating it. There has been a great deal of effort and considerable success in predicting microbial metabolic activities ...
New Insights into the Controls and Mechanisms of Plankton Productivity in Coastal Upwelling Waters of the Northern California Current System
Controls and Mechanisms Plankton Productivity Coastal Upwelling Waters Northern California Current System
2015/7/22
During the lifetime of the National Science Foundation's Coastal Ocean Processes program, four experiments were conducted on the US West Coast in the northern California Current System. Although each ...
The Biology and Ecology of Tintinnid Ciliates:Models for Marine Plankton
Biology and Ecology Tintinnid Ciliates Marine Plankton
2015/7/16
Single-celled eukaryotes called protists are vitally important to marine ecosystems. Protists with chloroplasts (algae) carry out most of the primary production in the sea. What feeds on this algal pr...
Addressing the impact of environmental uncertainty in plankton model calibration with a dedicated software system: the Marine Model Optimization Testbed
environmental uncertainty plankton model calibration a dedicated software system the Marine Model Optimization Testbed
2014/12/11
A wide variety of different plankton system models have been coupled with ocean circulation models, with the aim of understanding and predicting aspects of environmental change. However, an ability to...
Medusa-1.0: a new intermediate complexity plankton ecosystem model for the global domain
The sea is expected Plankton. Ecosystems The pump The carbon cycle. The terrestrial biosphere
2014/12/9
The ongoing, anthropogenically-driven changes to the global ocean are expected to have significant consequences for plankton ecosystems in the future. Because of the role that plankton play in the oce...
Trait-based representation of diatom functional diversity in a plankton functional type model of the eutrophied southern North Sea
diatom functional diversity North Sea
2014/11/28
We introduce a trait-based description of diatom functional diversity to an existing plankton functional type
(PFT) model, implemented for the eutrophied coastal ecosystem in the Southern Bight of th...
Seasonal dynamics of autotrophic and heterotrophic plankton metabolism and PCO2 in a subarctic Greenland fjord
Biological metabolic kinetics Greenland fjord
2014/10/16
We measured net planktonic community production (NCP), community respiration (CR), and gross primary
production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...

Species-dependent effects of crustacean plankton on a microbial community, assessed using an enclosure experiment in Lake Taihu, China
Species-dependent effects crustacean plankton microbial community assessed using an enclosure experiment Lake Taihu, China
2014/4/2
A mesocosm experiment was performed to evaluate the species-dependent effects of crustacean plankton on the microbial community in Lake Taihu, a large shallow eutrophic lake in China. Four dominant sp...
Consequences of UV-enhanced community respiration for plankton metabolic balance

2014/4/2
The net community production (NCP) of plankton communities affects their role as sources or sinks of
atmospheric CO2. Most estimates of NCP have been made by enclosing communities in bottles, general...

Effects of experimental warming and increased ultraviolet B radiation on the Mediterranean plankton food web
experimental warming increased ultraviolet
2014/4/4
The responses of the plankton food web to increases in temperature and ultraviolet B radiation (UVBR, 280–
320 nm) were experimentally investigated at a coastal Mediterranean site during spring. Eigh...
On some relationships between storms and plankton dynamics
some relationships between storms plankton dynamics
2010/9/10
The physico-chemical fields of the pelagic environment are constantly fluctuating at different spatial and temporal scales. Storms are extreme events of such fluctuations that cascade down to small sc...
Scavenging and retention of bismuth by marine plankton and biogenic particles
Scavenging retention bismuth marine plankton biogenic particles
2014/4/17
We did radiotracer experiments using207 Bi to quantify the bioavailability, accumulation, and retention of bismuth in marine plankton and biogenic detritus. The accumulation of207Bi by two species of ...
