An objective of this research is to evaluate the feasibility of the Gaussian distribution model's application for the vertical Chlorophyll-a (Chl-a) estimation in inner bay by the satellite remote sen...
Seaglider observations of blooms and subsurface chlorophyll maxima off the Washington coast
Seaglider observations of blooms and subsurface chlorophyll maxima off the Washington coast
2014/5/16
From September 2003 to December 2007, autonomous, underwater Seaglider continuously ran a V-shaped transect off Washington State from about 200-m water depth (i.e., at the break between the shelf and ...
Interactive influences of iron and light limitation on phytoplankton at subsurface chlorophyll maxima in the eastern North Pacific
Interactive influences of iron light limitation phytoplankton subsurface chlorophyll maxima eastern North Pacific
2014/4/18
The roles of iron and light as limiting and colimiting factors for phytoplankton growth in subsurface chlorophyll maxima (SCMs) were investigated in mesotrophic to oligotrophic waters of the Southern ...

Processes influencing phytoplankton bloom development in the southern Drake Passage were studied using shipboard iron-enrichment incubations conducted across a surface chlorophyll gradient near the An...
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected to nutrient levels
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected nutrient levels
2014/4/23
During the 1980s, a rapid increase in the Phytoplankton Colour Index (PCI), a semiquantitative visual estimate of algal biomass, was observed in the North Sea as part of a regionwide regime shift. Two...
Iron requirements of the pennate diatom Pseudo-nitzschia: Comparison of oceanic (high-nitrate, low-chlorophyll waters) and coastal species
pennate diatom Pseudo-nitzschia oceanic coastal species
2014/5/5
We quantified and compared physiological parameters and iron requirements of several oceanic Pseudonitzschia spp., newly isolated from the high-nitrate, low-chlorophyll waters of the northeast subarct...

Do wetland lakes exhibit alternative stable states? Submersed aquatic vegetation and chlorophyll in western boreal shallow lakes
wetland lakes stable states Submerged aquatic vegetation chlorophyll western boreal shallow lakes
2014/5/22
Shallow lakes often exhibit alternative vegetative states, one a clear-water state dominated by submersed aquatic vegetation (SAV) and the other a turbid state dominated by pelagic phytoplankton. We d...
