IMIS

During August, 1974, a cruise was conducted into the waters off Nova Scotia and Bay of Fundy and data were collected on the temperature, salinity and density profiles at 46 stations. Measurements were also made on nutrients (N02, N03, NH3, P04-P, Si02), phytoplankton biomass (cell numbers, chlorophyll a, phaeophytin, particulate carbon, particulate nitrogen) and carbon uptake at various levels of light energy on samples collected from 5 meter depth. These observations were continued at 2 hr. intervals for more than 24 hrs. at 3 fixed stations. The data are consistent with the hypothesis that subsurface waters upwelled at certain stations during the period of study. The OBIS collection is a subset of this dataset containing species distribution information.
