The diversity of Planctomycetes in glacier sediment, and freshwater and marine sediments in Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)
This study compares the phylogenetic diversity of Planctomycetes within the glacier soil, freshwater pond sediment and marine sediment. It was hypothesized that a source of bacteria to the pond and marine environments was coming from glacier melt, but this did not prove to be the case.
Bacterioplankton community structure and enzymatic activity in Barkley Sound, Canada, and its response to a simulated diatom bloom
This study examined the bacterioplankton community dynamics in Barkley Sound, located on Vancouver Island Canada, and the extent to which the community structure would change with the occurrence of a simulated diatom bloom. Bottle incubations were conducted using a diatom lysate to replicate bloom conditions. Bacterial relative ...
Diatom abundance and community structure in Barkley Sound, Vancouver Island, BC: significant impacts on primary productivity
This research measured diatoms and phytoplankton in Barkley Sound to understand more about the process of exporting carbon from the atmosphere to the deep ocean. The study had three objectives: 1) to measure the autotrophic phytoplankton biomass and estimate diatom abundance in the phytoplankton community; 2) to observe how ...
Abundance and distribution of bacteria and viruses in the various ecotypes of the Hawaiian Islands Florence
Viruses and bacteria are highly abundant in the marine realm. Many studies have shown that viruses often exceed bacteria in abundance by an order of magnitude. This study utilized epi-fluorescence microscopy and DAPI and SYBR stain to quantify abundance of the two entities in the waters of the Hawaiian Islands. The virus to ...
Diatom and dinoflagellate abundance and ecology in waters off the Hawaiian Coast
Diatoms and dinoflagellates are two groups of phytoplankton important in carbon sequestration, which affects climate change, and harmful algal blooms (HABs). Understanding their community ecology is important to our ability to make predictions about these issues. This study uses phytoplankton abundance and biomass at seven ...
