Microplastics Contamination in Sediment, Water, Snow/Ice, Fish and Seals of the Canadian Arctic: 2021-2022

Microplastics (MPs) contaminate the oceans from the poles to the equators and from the sea surface to the deep sea. In addition, MPs have been recorded in freshwater systems, including in lakes, rivers and streams globally. Not only an aquatic issue, MPs infiltrate terrestrial ecosystems in landfills, agricultural settings, along beaches, and even in the air. It therefore comes as no surprise that MPs have been identified as a global pollutant of concern that is capable of long-range transport and causing adverse effects in wildlife, but limited information is available for Canadian Arctic regions. Consequently, the NCP has identified assessing the presence and distribution of MPs in Arctic marine ecosystems a priority. The Arctic Monitoring and Assessment Programme (AMAP) has also added Marine Plastics and MPs to their list of Chemicals of Emerging Arctic Concern. As part of NCP and ArcticNet, air, water, sediment and zooplankton samples were collected from on board the CCGS Amundsen. Additionally, atmospheric related samples were collect in Alert and communities in NWT, snow samples from NWT, fish from three communities in NWT and seal stomachs from Resolute Bay.

Ship-Based Eddy Covariance Data, 2009 ArcticNet, Northwest Passage

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):

Underwater PAR and UVR downwelling irradiance profiles in the Southeastern Beaufort Sea in 2004

This dataset consists of vertical profiles of underwater downwelling irradiances at several UVR (305, 313, 320, 340 and 380nm) and PAR wavelengths, from June to August 2004. Vertical light profiles were performed using a PUV-511 underwater radiometer (Biospherical Instruments) that provides a measure of cosine-corrected downwelling irradiance in the UVR and PAR. Irradiances were corrected by the dark values and normalized to the ambient conditions at the beginning of the profile, using ambient values given by a GUV-510 surface radiometer (Biospherical Instruments) mounted on the top of the wheelhouse of the CCGS Amundsen.

Hull Mounted ADCP Current Data Collected by the CCGS Amundsen in the Canadian Arctic

The CCGS Amundsen is equipped with a RDI ADCP Ocean Surveyor (RDI os150), a ship-mounted current meter attached to the hull of the ship. The ship is also equipped of ice windows to protect the system while sailing through harsh arctic conditions. The current meter records continuous measures of the current along the ship transit route using a 150KHz sonar capable of covering the first 450m of the arctic water column. Since 2015 data are controlled using the Common Oceanographic Data Access System (CODAS, https://currents.soest.hawaii.edu/home/software/) of the University of Hawai'i, also adopted by the NOAA-National Centers for Environmental Information (NOAA-NCEI) to create the Joint Archive for Shipboard ADCP. Data are provided in NetCDF formats and follow the COARD (Cooperative Ocean/Atmosphere Research Data) convention. Detailed information and metadata are available in the documentation of the archive and in-built metadata files. Raw data since 2004 are available on demand.

Sediment and Invertebrate Sampling for Trophic Benthic Ecology Near the Nain Continental Shelf (Labrador Sea), 2019

Bulk and amino acid-specific stable isotope analyses, and morphological taxonomy will be the primary methods used for this project. Isotope analyses of carbon (C), nitrogen (N), hydrogen (H), and sulfur (S) will provide information on trophic interactions. Species richness and abundances will be used in biodiversity calculations. Sediment properties such as grain size and porosity will provide information on community structure and functioning. Phytopigment content will enhance knowledge of productivity at each location. Organisms used for isotope analyses were collected using an Agassiz trawl, whereas all other samples were collected using a box corer.
