BioChem: Copepod species composition and associated chlorophyll data from Resolute Passage (OBIS Canada)

This dataset includes data collected from the ice station set up in Resolute Passage, 74 degrees 40'N and 94 degrees 54'W between the years 1983 to 1989.

Plankton samples were collected using a 1/2m ring net with 100-200u mesh towed vertically from approximately 2 metres off the bottom to the surface. The samples collected were preserved in 4% formaldehyde and later analysed for species/stage composition for the dominant copepod taxa: Pseudocalanus, Metridia, Calanus hyperboreus, C. glacialis, Oithona, Oncaea, Microcalanus. All other species of copepods were lumped together into the category 'other'. Associated chlorophyll and phaeophytin data are available. The associated nutrient data was of poor quality and not archived. To investigate the plankton community structure and establish a baseline to monitor ecosystem changes in the Arctic.
