Existing information on Arctic marine food web structure is fragmented. Integrating data across research programs is an important strategy for building a baseline understanding...

Agassiz trawl was deployed from the CCGS Amundsen to collect macrofauna. Catches were passed through a 2 mm mesh sieve. When possible, specimens were identified to the lowest...

A useful tool for monitoring the ecological health of aquatic systems is by means of benthic invertebrate analysis in a biomonitoring approach. Here, we investigate an approach...

Samples were collected at two sites in the Eastern Canadian Arctic (Figure 1) aboard the scientific icebreaker CCGS Amundsen. The sampling positions at biogenic and non-biogenic...

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),...

Data were mainly collected from the CCGS Amundsen (2015 to 2019) and from the William-Kennedy (2019). An Agassiz trawl (1.5 m width × 0.7 m height, cod end of 0.5 cm mesh size)...

Hydrologic, geomorphological, invertebrate samples, and water quality data was collected from three rivers in the Greater Toronto Area: Ganatsekiagon Creek (Durham), Wilket...

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...

Coral samples were collected in Pond Inlet and Lancaster Sound in Baffin Bay using the CCGS Amundsen’s remotely operated vehicle (ROV). Samples from Agassiz trawl and box-core...

Incubations of 15 sediment cores were performed in a dark and temperature controlled room (ca 3°C). Five cores acted as controls; 13C, 15N labelled ice algae or phytoplankton...

Sample collections were made aboard the CCGS Amundsen during the ArcticNet field campaigns in August 2013 (Leg 1), July, August and October 2014 (Leg 1 & 3) and October 2015...

Bottom water (20 L per station) was collected at 11 stations in Baffin Bay using the CCGS Amundsen’s rosette system. Water was filtered aboard the vessel into glass microfiber...

Thyasirid bivalves were collected by sieving sediments collected using box cores aboard the Amundsen, from 2015 to 2017, around Baffin Island and at Saglek Bank. Specimens were...

Spectral reflectance measurements were taken using the panel substitution method with a dual-channel Ocean Optics Jaz in an underwater housing, while SCUBA diving. A standard...

Seabed sampling consisted of underwater video, sediment, and biological samples. Out of 301 attempted grab samples, 235 yielded sediments, biota or both. Over six hours of...

Benthic grab samples and underwater towed video samples were collected at long-term ecology sites while onboard the Government of Nunavut vessel MV Nulialjuk and CCGS Amundsen...

The study area extends from the North Water Polynya to the Chukchi Sea across five geographic regions: North Water Polynya, Canadian Archipelago, Amundsen Gulf, Beaufort Sea and...

Thermokarst lakes are widespread in subarctic regions and contribute to global carbon (C) cycling. The recent degradation of permafrost means that the basic limnological and...

Using macrofaunal biodiversity data as well as bacterial abundance, grain size, CHN, nutrient concentrations and onboard sediment core incubations we are trying to evaluate how...

We have collected subsamples of sediments retrieved from Baffin Bay during the ArcticNet funded Hidden Biodiversity expedition, in order to characterize their microbial...
