Organic Contaminants in Canadian Archipelago: Central and Eastern, 2011

Air, water, phytoplankton and zooplankton samples were collected on board the CCGS Amundsen in October 2011 as part of ArcticNet between Kugluktuk, NT and Quebec City, QC via Baffin Bay. The samples were analysed for legacy organochlorine pesticides (OCPs), current use pesticides (CUPs), per and polyfluoroalkyl substances (PFAS) and organophosphate flame retardants and plasticizers (OPs). The purpose of collecting air and water samples in the Canadian Archipelago was i) to continue the time trends of OCPs and CUPs, ii) to confirm the presence of PFAS observed in recent years and iii) establish baseline concentrations of OPs. The phytoplankton and zooplankton samples investigation will allow quantification of the above compounds in the lower food web and observe how these compounds move from the abiotic to biotic environment.  
Analysis was done by gas chromatograph-mass spectrometer (GC-MSD) and liquid-chromatography mass spec mass spec (LC-MS/MS). Four OPs, tri-phenyl phosphate (TPP), tris-(2-chloro ethyl) phosphate (TCEP), tris-(2-chloro propyl) phosphate (TCPP) and tris-(1,2-dichloro propyl) phosphate (TDCPP) were identified in air samples for the first time in Canadian Arctic air and levels are very high compared to levels of total PBDEs and other brominated flame retardants at Alert (Xiao et al., 2012). Due to these findings, archive samples from Alert and previous ArcticNet cruises were also analysed for OPs, thus establishing baseline concentrations in Canadian Arctic air in which future trends can be compared.

Benthic sediment and faunal sampling in outer Frobisher Bay, 2017-2018

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.

Fatty Acids, carotenoids, protist community and environmental parameters collected during a phytoplankton blooms in the Hudson Bay Complex.

The study was part of larger multidisciplinary investigations in the HBC aimed to understand (i) the effect of climate change on the quality of the Inuit local marine food (project BriGHT; Bridging Global Change, Inuit Health and the Transforming Arctic Ocean) as well as (ii) the contributions of climate change and hydroelectric regulation to the freshwater–marine coupling (project BaySys; The Hudson Bay System Study). Samples were collected from 7 to 12 July 2017 (BriGHT) and from 1 June to 12 July 2018 (BaySys) onboard the Canadian Coast Guard Icebreaker CCGS Amundsen using a Rosette system equipped with 12-L Niskin-type bottles and a conductivity, temperature, and depth (CTD) profiler (SBE-911, Sea-Bird Scientific, Bellevue, WA). The rosette was also equipped with a photosynthetically active radiation (PAR, 400 – 700 nm) sensor (scalar radiometer QSP-2300, Biospherical Instruments Inc., San Diego, CA) while a surface reference (QCR-2200, Biospherical Instruments Inc., San Diego, CA), measure incoming scalar PAR, was mounted to the ship’s main mast. In both years, discrete water samples for nutrients, taxonomy, pigments and lipids were collected at the surface and the deep chlorophyll maximum (DCM) directly from 12-L Niskin-type bottles that were closed on the upward cast then pre-filtered using a 200-μm Nylon. The duration (in days) since the ice breakup were extracted, for each station, from Nimbus-7 SMMR and DMSP SSM/I-SSMIS passive microwave data produced daily by the National Snow and Ice Data Center (Parkinson et al., 1996, updated yearly). In the current study, we defined the sea ice breakup by the day that the total ice concentration fell below 15%. We investigated 21 stations in 5 sub-regions (North-Western Hudson Bay, Eastern Hudson Bay, Narrows Strait, Hudson Strait as well as Ungava Bay. At the time of sampling, the sub-regions studied had different environmental settings conditioning their bloom stages. Pre- and post-bloom stages were associated with relatively low concentrations of bioactive molecules (either fatty acids or carotenoids) while bloom stages were associated with high concentrations of bioactive molecules.

2018 ROV video survey in SW Greenland aboard CCGS Amundsen (dives 68-69)

Two remotely operated vehicle (ROV) video surveys were conducted at the SW Greenland location, at depths of ~700-950 m in August 2018. The primary purpose of the ROV dives at this location was to video survey the area study the distribution, geology, and species associations to the reef-forming cold-water coral Lophelia pertusa. Another objective of these dives was to survey the area to identify a suitable location for piston coring. Lophelia pertusa coral colonies were observed on steep bedrock surfaces between 950 and 750 m water depth. Other corals observed at this site include Primnoa resedaeformis, Paragorgia arborea, soft corals, and sponges Asconema spp, Geodia spp., among others. No sampling took place at this location due to ROV issues.

C-band scatterometer - ArcticNet 2010 Expedition - Beaufort Sea

General description: A C-band polarimetric scatterometer was used to collect the backscattering signatures of new ice, first year ice, and multiyear ice in as many forms as possible during the fall freeze-up and winter period in Southern Beaufort Sea and Amundsen Gulf. This instrument is mounted on the port side of the ship (CCGS Amundsen) and the backscattering signatures were collected in conjunction with geophysical sampling of the region that was scanned in an attempt to provide the physical reasons for the electromagnetic interactions. This variable will be used in modeling studies and in coordinating in situ measurements with satellite data. 

Methology: The scatterometer measured the backscatter from the surface of interest. Incidence angles ranged from 20 to 60 degrees in 5 degree steps, with a swath of 60 degrees in the azimuth. Several scans were collected for statistical purposes (generally 5). Either during the scans, or immediately afterwards, geophysical sampling was performed in and around the region of the scan in order to gather ground truth data. The dataset contains unprocessed and processed polarimetric data as a function of incidence angle.

Assessing Persistent Organic Pollutants (POPs) in Canadian Arctic Air and Water as an Entry Point into the Arctic Food Chain, Northern Contaminants Program (INAC) and ArcticNet, 2019

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.

Amundsen Science 360 Landscape Imagery Data

This dataset includes photo mosaic, panoramic, and map of the surrounding environment of the ship. These photos were taken at a rate of 5 minute intervals. To have a visual of 360 deg around the vessel, the ship is equipped with three 180 deg AV20185 IP Camera manufactured by the Arecont company. Each camera can produce four photos from each of their four Field Of View (FOV) of 45deg and gives twelve photos for each acquisition. After each acquisition, the acquisition system automatically assembles the 12 photos together to create a 360° panoramic image. The assembling is done based on a template that matches pixels of one photo border to the corresponding pixels of the border of the adjacent photo. Each panorama is assembled according to the exact same pixel correspondence. Once a panorama is assembled, the acquisition system projects the panoramic image on a horizontal plan according to predetermined calibration parameters. Calibration parameters were determined by measuring at different points around the ship the distance between a zodiac (simultaneously taken on the photos) and the ship. The recorded distances are then used for georeferencing the pixels of the panorama on the plan. Geographical coordinates where each photos were taken are included in this dataset. The dataset of 2016 includes photos in Baffin Bay (3080 photos), Beaufort Sea (809 photos), Labrador Sea (3759 photos),  Nares Strait (810 photos), Northwest Passage (3416 photos), and Saint-Lawrence Gulf (192 photos).  The dataset of 2017 includes photos in Baffin Bay (3637 photos), Hudson and James Bay (2027photos), Labrador Sea (8451 photos), Northwest Passage (7175 photos) and Saint-Lawrence Gulf (2693 photos). The dataset of 2018 includes photos in Baffin Bay (781 photos), Hudson and James Bay (16165 photos), Labrador Sea (7783 photos), Northwest Passage (1264 photos) and Saint-Lawrence Gulf (1228 photos). The dataset of 2019 includes photos in Baffin Bay (30185 photos), Labrador Sea (41477 photos), Nares Strait (9257 photos), Northwest Passage (14261 photos) and Saint-Lawrence Gulf (2980 photos).
