The Canada¿s Three Ocean¿s project is designed to take a snapshot of all three of the oceans surrounding Canada in 2007 and 2008. In doing this, we will evaluate the connections among the Arctic, Pacific and Atlantic Oceans, provide a baseline of biological, chemical and physical measurements of the ocean environment and leave a legacy that can be used as the basis for long term monitoring of our oceans. In 2008, following the success of the 2007 season, two Canadian Coast Guard icebreakers left their home ports on the Atlantic and Pacific coasts carrying scientists who observed the environment around them by measuring a wide range of properties, from the numbers and type of seabirds, to the plankton in the water, the nutrients in the seawater to the physical and chemical properties of seawater that tell the story of the water¿s current movement and past history. By the time they crossed paths in the Canadian Arctic Archipelago, 14000km of ocean from Victoria to Halifax through the Northwest Passage had been observed in one season. Researchers from government and universities, students at all levels from high school and up, writers, photographers, and technicians both experienced and in training participated in this project. Once home from sea they have been analysing, processing and plotting their results which together with the results from 2007 give two single season snapshots of Canada¿s surrounding oceans.

The CTD data was obtained during LEG 02 of the 2003 CASES scientific cruise #0304. This Leg was carried out from October 15th 2003 to November 25th 2003 aboard the CCGS Amundsen. There were 147 CTD casts in Leg 2. All of these casts, associated to 109 oceanographic stations, are located in the Beaufort Sea research area. The following parameters were measured: temperature, conductivity and pressure (with a Sea-Bird 911 probe), oxygen (Sea-Bird 43), pH (Seabird 18), fluorescence (Seapoint fluorometer), nitrates (Satlantic MBARI ISUS), transmittance (Wetlabs C-Star transmissometer), PAR/Irradiance and SPAR/Irradiance (Biospherical Instruments QC2300). Data were quality controlled. Data are available on the Polar Data Catalogue and at the Marine Environmental Data Service (MEDS) of Fisheries and Ocean Canada.
