Sinking export of organic material was investigated during the fall of 2007, using free-drifting, short-term particle interceptor traps . The particle interceptor traps were deployed at 6 stations along a transect spanning between the North Water polynya (Baffin Bay) and the Beaufort Sea. The traps were deployed from the CCGS Amundsen at three depths below the euphotic zone (50, 100 and 150 m) for a period between 8 and 22 hours. The analyses on the sinking material included total chlorophyll a and phaopigments (fluorometric determination), particulate organic carbon and nitrogen, biogenic silica, cell composition and abundance and fecal pellet abundance.

Acoustic data was generated from the multibeam Kongsberg Simrad EM300 and EM302 multibeam sonar system on the CCGS Amundsen. This bathymetric data subset covers the Greenlandic Economic Exclusive Zone (EEZ), i.e. outside of the 12 nm territorial sea extent and within the 200 nm EZZ, from 2003 to 2014. The datasets consist of high-resolution bathymetry and acoustic backscatter imagery collected 24 hours a day, whenever the ship was in transit or had dedicated survey time. Standard collection settings used dual-ping, FM pulse, auto depth mode, angular coverage of +/- 60 degrees and high density equidistant beamforming. The SIS software was used to collect the data, while near real-time cleaning of data outliers was done using the Caris HIPS&SIPS software after conversion to Generic Sensor Format (GSF) for input into MB-System database manager. Inertial Measurement Unit (IMU) data was parsed by SIS from a POSMv 320 v.4. RTG GPS data from the CNav 3050 GPS was used to correct and improve the position output from the POSMv with RTCM correction. Soundspeed information was either from CTD Rosette casts, MVP300 data or simulated from the World Ocean Atlas 2009 database. The resolution of data is 10 metres. Available tiles are in ESRI grid format (.asc). The OMG of University of New Brunswick were responsible for 2003-2013 data (http://www.omg.unb.ca/Projects). From 2014, responsibility switched to the Marine Geomorphology Laboratory of Laval University.

The CTD data was obtained during the 2011 ArcticNet scientific cruise #1103a. The data were collected from September 26 to October 3, 2011, aboard the CCGS Amundsen. There were 35 casts associated to 27 stations, located in Baffin Bay and the Northwest Passage. The following parameters were measured: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), dissolved oxygen (Sea-Bird SBE-43), fluorescence (Seapoint chlorophyll fluorometer), CDOM (Wetlabs FL(RT)D), nitrate concentration (Satlantic MBARI-ISUS 5T), transmittance (Wetlabs C-Star transmissometer), light intensity (PAR; LI-COR Biosciences) and surface light intensity (sPAR; LI-COR Biosciences). 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.
