Raw data collected using a creative webcam and an acryllic hemispherical mirror dome installed on the roof of the wheelhouse of the CCGS Amundsen. Data were collected from summer to fall 2009 in the Southern Beaufort Sea and Amundsen Gulf areas.

During the ArcticNet annual cruises of the research icebreaker CCGS Amundsen, characteristics of the near-surface atmosphere are monitored in conjunction with surface sea water properties to observe the relationship between the surface micro-climate and the air-sea exchange , with particular interest in CO2. Central to this integrated dataset is an eddy covariance system used to monitor fluxes of CO2, H2O, heat and momentum. The system continuously sampled the following variables at a rate of 10 Hz (instrument used to collect each variable is in parentheses, and approximate instrument height above surface is indicated): 3D wind velocity (Gill WindMaster Pro ultra-sonic anemometer) - 15m; sonic air temperature (Gill WindMaster Pro ultra-sonic anemometer) - 15m; CO2 molar concentration (LI7500 open path gas analyzer) - 15m; H2O molar concentration (LI7500 open path gas analyzer) - 15m; CO2 mixing ratio (LI7000 integrated into a closed path system) - 15m; H2O mixing ratio (LI7000 integrated into a closed path system) - 15m; and, 3D ship motion - angular rates and accelerations (MotionPak, Systron Donner) - 13m. All instruments were mounted on a meteorological tower on the bow of the research icebreaker CCGS Amundsen.

Sponges were sampled from multiple sites in the Northeast Atlantic from multiple cruises aboard the CCGS Amundsen. Benthic sponges were obtained through Box cores, Agassiz trawls, and through targeted sampling using the SuMO ROV. Sponges were photographed on board and in-situ when possible (using ROV camera). Collected sponges were retained for taxonomic analysis. Whole or portions of each collected sponge were preserved in 96% ethanol to prevent DNA degradation. Larger sponge fragments were frozen on board. Collected sponges are to be subsampled for morphology-based taxonomy (analysis of spicule structure and body form), and for molecular taxonomy through extraction and amplification of cytochrome oxidase subunit I (COI) mitochondrial DNA fragments for DNA barcoding. In total, 112 separate sponges were sampled during the 2015/2016 leg from depths ranging between 80-1148 metres and encompassing latitudes 60°18N to 68°15N. 31 specimens were collected using the ROV and therefore have associated in-situ video imagery which will aid in species identifications and descriptions. In total, 48 separate sponges were sampled during the 2017 leg from depths between 84 - 875 metres and encompassing latitudes 62°34N to 78°19N. Nine specimens were collected using the ROV and therefore have associated in-situ video imagery which will aid in species identifications and descriptions. In-situ videos are not included in the dataset but will be made available upon request. See Links to data section for contact.

A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in October 2015 at Inner Frobisher Bay, Nunavut. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at a depth of ~59-139 m along a transect line 1.2 km long.

We collected air, water, sediment samples in the summer of 2019 from on board the CCGS Amundsen in the central and eastern Canadian Archipelago. We also collected air and water (grab and passive) from the CCGS Laurier in the Beaufort Sea and the R/V William Kennedy in the western Hudson Bay and Chesterfield Inlet. Air samples were continuously collected form the very front of the bow of the ship to reduce contamination from the smoke stack. The air sampler consisted of a filter to collect the particulate followed by a cartridge containing a sandwich of polyurethane foam and XAD resin to sorb the gas phase. Several types of water samples were collected: target compounds were concentrated from grab surface samples (200-L) by filtering through a column of XAD resin. Grab samples for flame retardants were collected in glass bottles and shipped back to the lab for processing. Grab samples for per-fluorinated compounds were collected at the surface and at two-three depths in plastic bottles and shipped back to the lab for processing. Sediment samples were collected from the box corer, the top 0-5cam was collected. Samples were frozen and shipped back to the lab for processing.

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 all-sky camera system consists of a Nikkon D-90 camera, with a wide-angle fisheye lens, a homemade enclosure with clear acrylic dome end-cap, and a small heater on a thermostat. The system is mounted on a small 'crows nest' above the wheelhouse on the CCGS Amundsen. Maintenance checks were performed daily.

In 2017 and 2018, we sampled about 20 locations across Frobisher Bay, mostly in the deeper portions of outer Frobisher Bay that are only accessible for sampling from large ships. Sample stations were chosen to span the range of depth and slope values in the multibeam sonar dataset, and in 2018 sampling, also included gross bottom morphology, such as ridges and troughs. We also targeted some particular geomorphic features, such as suspected submarine extensions of moraines. In 2017, bottom samples were acquired using box-cores, and small scientific trawl (Agassiz trawl). In 2018, bottom samples were acquired using box-cores, combined with a drop-video camera. Agassiz trawls were collected at two stations in 2018. Sediment samples were described visually and subsamples frozen for grain size and organic content analysis. Where informative, subsamples of lithic fragments within the sediments were kept for mapping. Bottom faunal samples were enumerated and preserved in 2% formalin in seawater, except for larger faunal samples such as soft corals, which were frozen.

The CTD data was obtained during the 2005 ArcticNet scientific cruise #0501. The data were collected from September 1 to 14, 2005, aboard the CCGS Amundsen. There were 62 casts, associated to 30 oceanographic stations, in the Beaufort Sea. The following parameters were measured: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), 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 Oceans Canada.

Ocean Mapping Group acoustic data generated from the 2011 multibeam sonar survey on the 2011 CCGS Amundsen ArcticNet Cruise. The data include high-resolution bathymetry and acoustic backscatter imagery collected 24 hours a day, whenever the ship was in transit or had dedicated survey time.
