Shipborne Dissolved Organic Gas Measurements in Depth Profiles and Underway Seawater (Methanol, Acetone, Acetaldehyde, DMS, Isoprene) Amundsen 2017

Dissolved concentrations of these gases were measured using a segmented flow coil equilibrator (SFCE) coupled to a Proton Transfer Reaction Mass Spectrometer (PTR-MS). For more information, please refer to Wohl, C., Capelle, D., Jones, A., Sturges, W. T., Nightingale, P. D., Else, B. G. T., and Yang, M.: Segmented flow coil equilibrator coupled to a proton-transfer-reaction mass spectrometer for measurements of a broad range of volatile organic compounds in seawater, Ocean Sci., 15, 925–940, https://doi.org/10.5194/os-15-925-2019, 2019.

Detailed description of the installation on board and the data analysis specific to this deployment can be found in the data citation.

Briefly, the SFCE-PTR-MS was set up in one of the labs near the front of the ship and used to sample either discrete samples from depth profiles or underway seawater from the main seawater inlet of the ship.

The research vessel travelled from Iqaluit northwards through Davis Strait and Baffin Bay to reach Smith Sound. In this area, more intense depth profile sampling was carried out. The vessel then travelled to Pond Inlet and Resolute. Sampling ended south of Resolute in Peel Sound.

Depth profiles of dissolved gas concentrations were measured from the Rosette-mounted Niskin bottles as discrete samples from the near surface (about 2 m) to 60 m depth at a total of 21 stations as per availability. The exact sampling depth as determined by the CTD crew is listed in the "CTD concentrations" data file.

When logistically feasible at station, a handheld vertical 5 dm^(3) Niskin bottle was deployed off the front starboard side of the ship to sample approximately the top 30 cm from the ocean surface. This was done by bringing the Niskin bottle up from approximately 3 m and firing it just before it reached the surface using rope marks as depth indicators, similar to described in Ahmed et al. (2020). Samples collected with this method are marked as sampled from 0.3 m in the "CTD concentrations" data file. The AMSR2 passive microwave sea ice concentration (SIC) satellite product (daily, 3.125 km x 3,125 km resolution) (Spreen et al., 2008) was used to create a time series of sea ice concentration along the cruise track.

Integrated Beaufort Observatory (iBO) mooring data, 2015-2018

The main integrated Beaufort Observatory (iBO) sampling platform is composed of 7 tautline moorings located in waters ranging from 20 to 750 m at key locations from the Mackenzie Canyon, to the mid and outer central shelf and slope, up to the remote northwestern area off Banks Island. BR-G, BR-K, BR-1 and BR-3 moorings are under the responsibility of ArcticNet while DFO-1, DFO-2 and DFO-9 are under the Institute of Ocean Sciences (DFO) responsibility. Moored instruments include acoustic doppler current profilers from 75 to 2000 MHz to measure current velocity, current direction, ice drift and plankton/particulates backscattering; ice-profiling sonars for the measurement of sea ice thickness, under-ice topography and for assessing waves and storm surges; water property sensors for salinity (S), temperature (T), turbidity, chlorophyll and dissolved oxygen; and automated sediment traps that collect sinking particles for the measurement of biogeochemical fluxes. 2015-2018 ArcticNet data will be quality assessed/quality controlled (QA/QC) and publicly available through the Polar Data Catalogue in 2022. The moorings were deployed and will be recovered from the CCGS Amundsen and Laurier Icebreakers.

Zooplankton and Algae Mercury Data in Amundsen Gulf, 2008

Sampling took place on legs 6, 7, 8b, and 9 of the CFL project on the CCGS Amundsen (2008). Zooplankton were sampled with a 1x1m2 (200 µm mesh) net through the moon-pool and with a 1m diameter (200 µm mesh) ring net on the ice at ice covered stations. In open water, samples were collected with 2x1 sq.m (500 µm mesh), 4x1 sq.m (500 and 200 µm mesh), and rectangular mid-water trawl (1600 µm mesh). Samples were live sorted to species and frozen at -25C. Algae were collected from the bottom ice via ice cores and the dive program, from the ice interface/surface water with a Hg clean Niskin and a hose and pump on a 1m arm, and from the chlorophyll a maximum depth via the rosette. Samples in ice were frozen in the dark, while samples in water were filtered via dual filtration following Morrison and Watras (1999) and filters were frozen at -25C. Zooplankton species Calanus glacialis and Calanus hyperboreus were analyzed for total mercury using CVAAS; C. hyperboreus was also analyzed for methyl mercury via Gas Chromatography Atomic Fluorescence Spectrophotometry (GC AFS). The algae samples were analyzed for THg using cold vapour atomic absorption spectrometry (CVAAS) and MeHg using cold vapour atomic fluorescence spectroscopy (CVAFS).

A remotely operated vehicle (ROV) video survey was conducted at the NE Hatton Sill location, at a depth of ~620 m in August 2018. The primary purpose of the ROV dive at this location was to obtain video-transect data for species composition determination, site characterization and depth distribution of corals and sponges, and to collect live and dead corals and sponges. Bottom type was mainly sand and gravel with occasional boulders. Semi-consolidated sand was observed at various points within the dive. Corals observed during this dive include Primnoa resedaeformis (including dead skeletons), soft corals, mushroom corals (e.g. Anthomastus sp.), Paramuricea sp., Radicipes sp., sea pens, sponges including Asconema spp. and Geodia spp.

AVOS Meteorological Data collected by the CCGS Amundsen in the Canadian Arctic

Environment Canada installed a meteorological system on the Voluntary Observing Ship (VOS) scheme part of the CCGS Amundsen. The system is composed of a Digital Barometer (Vaisala PTB-210), an R.M Anemometer (Young 05103) and a Humidity-Temperature Meteorological sensor (Rotronic MP101). The system continuously recorded Atmospheric pressure, Wind Speed and Direction, Air temperature and Humidity every 4 seconds for the CCGS Amundsen expeditions between 2004 and 2021. No data was collected in 2012 since the vessel was undergoing maintenance (dry docks). The true wind was directly calculated by the system using the ship's gyrocompass, the recorded apparent wind and Global Positioning System (GPS) data (speed and track of the ship from POS-MV and C-NAV Differential Global Navigation Satellite System (DGNSS) Precise Point positioning systems). Then the AVOS system averaged the data at 10 minute or hourly intervals. Outliers and suspicious measurements were removed from the dataset and the resulting controlled data are provided at 10 minute or hourly intervals for each day of the expeditions. Research programs participating in the Amundsen expeditions between 2004 and 2023 include CASES, ArcticNet, CFL, Geotraces, Malina, IOL and BP, BREA, Weston, Netcare, JAMSTEC, Statoil and iBO, GreenEdge, BaySys, Sentinel North, Nunavik Inuit Health Survey, Kitikmeot Marine Ecosystems Study, AZOMP, ISECOLD, KEBABB, CHS, NRCan, PeCaBeau, Dark Edge, and RADCARBBS.
