In July 2014 a Super Mohawk (SuMo) remotely operated vehicle (ROV) aboard the CCGS Amundsen was used to video-survey a deep-water environment at Home Bay. A video-transect ~2.2 km long was followed across depths of 700-750 m. Videos and photographs were obtained using a high-definition camera, and specimens of invertebrates (sponges) were collected using the ROV.

The CTD data was obtained during leg #0602 of the 2006 ArcticNet scientific cruise. The data were collected from September 4 to 20, 2006, aboard the CCGS Amundsen. There were 72 casts, associated to 39 oceanographic stations, in the Northern Baffin Bay research area. The following parameters were measured: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), dissolved oxygen (Sea-Bird SBE-43), pH (Sea-Bird SBE-18-I), fluorescence (Seapoint chlorophyll fluorometer), nitrate concentration (Satlantic MBARI-ISUS 5T), transmittance (Wetlabs C-Star transmissiometer), light intensity (PAR; Biospherical Instruments QCP2300) and surface light intensity (sPAR; Biospherical Instruments QCP2200). Quality control procedures were applied to the data. Data are available on the Polar Data Catalogue and at the Marine Environmental Data Service (MEDS) of Fisheries and Oceans Canada.

The distribution of dissolved organic carbon (DOC) in the water column of the Canadian High Arctic was investigated in 2006, as part of the ArcticNet program. Summer-fall DOC concentrations were measured at 27 stations between 4 September and 17 October 2006. Samples were collected using the rosette onboard the CCGS Amundsen. Euphotic zone sampling depths corresponded to surface irradiances between 0.2 and 100% as well as the chlorophyll a maximum depth. Aphotic sampling depths ranged from 75 m to the bottom waters.

The CTD data was obtained during leg #0602 of the 2006 ArcticNet scientific cruise. The data were collected from August 22 to 31, 2006, aboard the CCGS Amundsen. There were 9 casts, associated to 6 oceanographic stations, in the Labrador Sea research area. The following parameters were measured: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), dissolved oxygen (Sea-Bird SBE-43), pH (Sea-Bird SBE-18-I), fluorescence (Seapoint chlorophyll fluorometer), nitrate concentration (Satlantic MBARI-ISUS 5T), transmittance (Wetlabs C-Star transmissiometer), light intensity (PAR; Biospherical Instruments QCP2300) and surface light intensity (sPAR; Biospherical Instruments QCP2200). Quality control procedures were applied to the data. Data are available on the Polar Data Catalogue and at the Marine Environmental Data Service (MEDS) of Fisheries and Oceans Canada.

The meteorological observatory Polarstern continuously acquires meteorological parameters during times of ship operation. Measurements are taken on various locations on the vessel, instrument heights above sea level are given below. All data is quality controlled. Measurements are checked daily on board by the operator and again prior to publication. Knowingly affected or erroneous data is removed.

The CTD data was obtained during LEG 06 of the 2004 CASES scientific cruise #0403. This Leg was carried out from March 31th 2004 to May 12th 2004 aboard the CCGS Amundsen. There were 91 CTD casts in Leg 6. All of these casts, associated to the overwintering oceanographic station, are located in 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.
