Copepoda collected from Fletcher's Ice Island (T-3) in the Canadian Basin of the Arctic Ocean.Entry ID: ArcOD_2008P4
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.

Quality Between June 1966 and in December 1969, zooplankton samples were collected using either plankton-pumping system. a modified Juday closing net 1m in diameter with a 215 um Nitex mesh , a newly designed net that had a square mouth opening 2m on a side or a 3m2 net with a 215 um Nitex mesh. The volume of water filtered by the nets was estimated by multiplying the area of the mouth opening by the ... depth interval sampled. The 1-m net samples in the summer of 1967 covered depth intervals of 10m. From September 1967, the 1-m and 2-m nets sampled 20m intervals to 200 m, 50 m intervals from 200-300m, 100m intervals from 300 to 1000m, and 500m intervals from 1000 to 2000m. The samples were preserved in 5% formaldehyde solution buffered with sodium borate.
Process_Description: Added AOOS/IOOS core variables. Added ArcOD archive information. Changed an attrlabl from cataloguenumber to catalognumber to match the column name in the original XLS spreadsheet.
