Wavelength-specific light attenuation, chlorophyll concentration and phytoplankton communities
(2007-05)
This study evaluates the link between red and blue light intensity, chlorophyll concentration and phytoplankton community structure. Light profiles and water samples were taken at thirteen stations in Puget Sound including Dabob Bay (Hood Canal), Elliot Bay (Main Basin), the Strait of Juan de Fuca and the Skagit River Mouth ...
The effect of lower pH on phytoplankton growth in the Galapagos Archipelago
(2006-03)
Average ocean pH has dropped 0.1 units over the last 100 years to its current level of 8.1. Models suggest that ocean pH could further drop by up to 0.7 units within the next 300 years. This research focused on the effect of lower pH on marine phytoplankton in water samples taken from two locations around the Galapagos ...
Composition and distribution of phytoplankton around the Galapagos Archipelago
(2006-03)
The Galapagos Islands marine ecosystem has regionally high primary production and
chlorophyll concentrations that are uncharacteristic of the surrounding high-nitrate low chlorophyll waters of the Eastern Equatorial Pacific. Even with these high concentrations of
phytoplankton, their abundance still remains highly variable ...
Inter-island comparison of phytoplankton growth rates and herbivory rates
(2006-03)
The marine ecosystem around the Galapagos Archipelago is characterized by regionally high primary production and chlorophyll a
concentrations that are uncharacteristic of the surrounding waters of the Eastern Equatorial
Pacific. Phytoplankton growth and microzooplankton grazing rates were investigated during a cruise from ...
