- Physical and chemical data from the Canada Basin, August 2004
- abstract: The physical and chemical water properties of the Arctic Ocean's Canada Basin were measured during a Joint Ocean Ice Study (JOIS) expedition aboard the CCGS Louis S. St-Laurent from 29 July - 2 September, 2004 (Institute of Ocean Sciences Mission Number 2004-16). The objectives of the program was to investigate the storage of freshwater in the Beaufort Gyre, water mass and circulation, the inter-annual variability of water properties, and the distribution and concentration of bacteria and zooplankton. This report provides a summary of all science activities together with data collected from CTD/rosette casts. The CTD data consists of pressure, temperature, salinity, oxygen, transmission and fluorescence sensor data and the bottle data include salinity, oxygen, nutrients, 0, barium, chlorophyll a and bacteria. Sampling and analytical methods are described. Other samples collected but not included in this report are also listed.
