The effect of lower pH on phytoplankton growth in the Galapagos Archipelago
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 ...
Wavelength-specific light attenuation, chlorophyll concentration and phytoplankton communities
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 ...
Composition and distribution of phytoplankton around the Galapagos Archipelago
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
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 ...
Relationship between Bottom Water Oxygen Concentration and Palmitic Acid Preservation in Saanich Inlet, BC and Hood Canal, WA
The global carbon cycle in the ocean is closely associated with dissolved oxygen in the surface ocean. Phytoplankton produce oxygen, and the oxygen in the atmosphere and surface seawater diffuses down to the seafloor. Dead phytoplankton, at the same time, contribute to respiration in the bottom water, consuming the bottom ...
Comparing King County CTD Data with Phytoplankton Biomass and Abundance in Puget Sound’s Main Basin to Determine Leading Causes of Harmful Algal Blooms
This study investigates the relationship between phytoplankton growth and different environmental factors, hypothesizing that an increase in the stratification of Puget Sound’s Main Basin will result in an increase in phytoplankton biomass and the possibility of harmful algal blooms (HABs). CTD data was collected from 7 ...
