Plankton and nekton of the northeast Newfoundland Shelf and Grand Banks in 1998 / Edgar L. Dalley, John T. Anderson and Denise J. Davis.: Fs70-1/1999-142E-PDF

Large scale surveys of the marine pelagic environment off Newfoundland and Labrador (NAFO Divisions 2J3KLNO) have been carried out during late summer since 1994. The survey was originally designed to measure the abundance of pre-recruit Atlantic cod during the pelagic juvenile fish stage. Also an independent measure of pre-recruit abundance of Northwest Atlantic capelin at the larval stage (0-group) and as one-year-old capelin (1+) was sought. In addition, it was designed as a multispecies measure of the state of the pelagic ecosystem and changes in it. The survey was undertaken for a fifth consecutive year in August/September 1998. The purpose of this document is to describe the temperature, plankton and nekton biomass and structure of this large zoogeographic area during 1998, in relation to the 4 previous years. Day/night variability in catch rates of 23 biological variables is examined each year of the survey. Following adjustments for any diel variability, these variables, along with 2 temperature measures, are statistically examined for differences among years (1994-98) and also for spatial patterns throughout the area.
