Description:

Abstract:: This report contains tabulations of abundance of Copepoda collected from Fletcher's Ice Island (T-3) on a drift track in the Canadian Basin of the Arctic Ocean during 1966 and 1967. Samples were taken, using a plankton-pumping system, at 5-m depth intervals from 5 to 185 m, The copepods were identified and enumerated as 25 species, unidentified immature copepodites and nauplii; five species were divided into males, females, and juveniles. Data for each sample include the sampling gear used, the date, time, and depth of sampling and volume of water sampled. These data were collected to begin a description of the vertical and seasonal distributions of zooplankton as part of a long-term study of primary productivity and energy flow in the Arctic Ocean. Non Copepod tabulations and associated chlorophyll concentrations are reported in other datasets. The other groups of zooplankton can be found in Scott, D.A. and T.Saunders English Zooplankton other than Copepoda collected from Fletcher’s Ice Island (T-3) in the Canadian Basin of the Arctic Ocean . University of Washington, Technical report No 241 and in a second dataset served by ArcOD.
Purpose:: The objectives of this portion of the study were to evaluate the effectiveness of a plankton-pumping system and two sizes of plankton nets for sampling copepods from Fletcher's Ice Island (T-3), to obtain a description of the vertical and seasonal distributions of the zooplankton.

Metadata uses WoRMS; www.marinespecies.org to generate the taxonomic hierarchy within this dataset. Some species names were updated to be consistent

Taxonomic_Procedures:

The copepods to be counted were placed in a clear plastic tray 6 x 7 cm, marked with a 1-cm grid. A binocular dissecting microscope was used to examine the copepods. The BHT color preservative often made the samples oily and difficult to examine, but color retention was markedly enhanced. The copepods were identified and enumerated as 25 species, unidentified immature copepodites and nauplii; five species, (Microcalanus pygmaeus, Metridia longa, Calanus hyperboreus, Calanus glacialis and Paraeuchaeta sp.) were divided into males, females, and juveniles. The abundance was computed as numbers per 100m3.
