| Summary: | This report contains tabulations of abundance of zooplankton other than 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, and with two sizes of closing plankton nets at intervals between 0 and 2000 m. The organisms were identified and enumerated as 44 categories of species and larger taxonomic groups. Data for each sample include the sampling gear used; the date, time, and depth of sampling; the number of categories in the sample; and the volume of water filtered; 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. The objectives of this portion of the study were: (1) to evaluate the effectiveness of a plankton-pumping system and two sizes of plankton nets for sampling zooplankton other than copepods from Fletcher's Ice Island (T-3), and (2) to obtain a description of the vertical and seasonal distributions of the zooplankton. The sampling pattern was designed to facilitate statistical analyses to obtain estimates of the variability associated with depth, seasonal, and diel differences. |
