Bacterial growth rates and bacterivory around the Galápagos Islands
The equatorial Pacific is an HNLC (high-nitrate, low chlorophyll) region, with the exception of the area around the Galápagos Islands, where there is commonly a relatively large standing stock of phytoplankton. In this experiment, the growth rates of bacteria and the grazing rates of the organisms that feed on bacteria were ...
Temporal and comparative variability of Iron and Carbon Dioxide of Loihi Seamount hydrothermal systems
Hydrothermal systems are visible representations of geological processes at work. Since their discovery, studies have shown them to be remarkable natural features with unique properties, venting fluids at extreme temperatures and supporting unusual biological communities. This study evaluates the effect of recent eruptions ...
Bacterial abundances and their relationship to iron around the Galápagos Islands, Ecuador
In an attempt to characterize the influence of an iron source on bacteria around the Galapagos Islands, bacteria were sampled at the surface and at four different depths from the R/V Thomas G. Thompson during 13-15 January 2006. This project hypothesized that the islands provided some form of iron source for the bacteria. ...
Zooplankton community composition and size distribution in relation to phytoplankton in the Galapagos Islands
Understanding the properties of zooplankton and their ecosystems is vital to fixing potential problems that may occur in the ecosystems. Over the years, iron fertilization has been thought to be the key to stop global warming; many studies have been done on the removal of carbon in the atmosphere by the phytoplankton in the ...
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 ...
