This report presents a tabulation of all oceanographic and biological data collected during the summers of 1989 and 1990 in two fjords, Sugluk Inlet and Wakeham Bay, located on the Quebec coast in western Hudson Strait. The data set includes information on the vertical distribution of temperature, salinity, nutrients (PO4, NO3), and oxygen as well as total, particulate and dissolved organic carbon, bacterial and phytoplankton counts, chlorophyll a, and the composition and abundance of the phytoplankton and zooplankton communities. In Sugluk Inlet the vertical distribution of temperature, salinity and zooplankton in the vicinity of the fjord sill was examined at intervals during a tidal cycle. The water flow across the sill of Sugluk Inlet was measured during a two week period by means of a moored current meter. (DBO).

Sedimentation of phytoplankton provides food and energy for zoobenthic communities. In this study the rates, species composition and biomass of phytoplankton input to Frobisher Bay sediments were examined during ice (late November to July) and open water (late July to October) periods from 1982 to 1985. The rates were higher on the sea bed than at 20 m. The minimum rate (3x105 cells•m-2•day-1) of sedimentation occurred during the early part of the ice period. It increased as the ice thickened and reached a maximum of 2.8x108 cells•m-2•day-1 after the phytoplankton bloom at the beginning of the oper water period in the first two weeks of August. The sedimented phytoplankton was dominated by diatoms, with a great majority of pennate species during the spring (April to June) and centric forms during the summer (July to August). Green flagellates, dinaflagellates and chrysophytes occurred as a low percentage of the total population in all seasons. Other indicators (chlorophyll a and phaeopigments) showed highest biomass levels in the deepest traps. They were consintently low during the winter (December to March) and reached their maxima during the open-water period of summer. Their abundance was correlated with the seasonal cycle of the phytoplankton in the water column.©1987 Springer-Verlag
PINKEWYCZ, N., S.I.C. HSIAO, 1987. Phytoplankton data from the southern Beaufort Sea. Can. Data Rep. Fish. Aquat. Sci., 637, 25 p .
Water samples collected in the southern Beaufort Sea during the spring of 1975 were analyzed quantitatively for phytoplankton. Thirty-nine genera and 60 species were identified. The diatoms were represented by 42 species (9 centric and 33 pennate), the green algae by 5, the golden-yellow algae by 3, the euglenoids by 3, and the dinoflagellates by 7 species. The diatoms comprised the largest group in terms of numbers of species and cells.
Phytoplankton data from collections during late summer and early fall of 1984 and 1985 in northeastern Ungava Bay are tabulated. Fifty-four genera and 102 species were identified. The diatoms were the largest group in terms of the number of cells and species. Among them, centric diatoms had fewer species but a greater abundance of cells than the pennate diatoms. Chlorophytes, chrysophytes, blue-green algae, euglenoids and dinoflagellates occurred in lower numbers in terms of both cells and species. Seawater temperature ranged from 0.2 °C in deeper water ot 3.2 °C near the surface, with most values lying between 1.5 °C and 2.0 °C. Salinity remained consistently between 30 ppt and 32 ppt except at Station 7.

Phytoplankton samples were collected from 23 stations at depths of 1, 5, 20, 50, 100 and 200 m in eastern Jones Sound, eastern Lancaster Sound and western Baffin Bay during the summer and fall of 1979. These samples were quantitatively analyzed for species composition and abundance. In terms of numbers of species and cells, the diatoms comprised the largest group; green algae, chrysophytes, euglenoids and dinoflagellates occurred in lower numbers.
