From July 15 – August 2, 2024, 6 CSSF team members supported Dalhousie University, the National Oceanic and Atmospheric Administration (NOAA) and Fisheries and Oceans Canada (DFO) aboard the R/V Henry B. Bigelow for the Cross-border Coral Habitat Exploration (CroCHEt) Expedition in the Gulf of Maine and in submarine canyons on the continental slope, including two in the Northeast Canyons and Seamounts Marine National Monument. The aims of the scientific team were to answer several questions about deep-water corals and to maintain successful collaboration between Canadian and US scientists. Scientists from Dalhousie University, the Delaware Museum of Nature and Science, DFO, and NOAA all participated. The expedition had 8 scientific objectives: 1) conduct video surveys and collect specimens at various locations, 2) explore new areas that may be of interest for protection, 3) evaluate deep-water coral abundance and spatial distribution, 4) collect fauna for taxonomic, reproductive, age, and isotopic analyses, 5) collect data for long-term monitoring in conservation areas, 6) undertake onboard experiments on temperature tolerance of select coral species, 7) collect water samples for eDNA analysis, and 8) collect multibeam data. Work that required the expertise of our team and ROPOS included the collection of imagery, biological samples, and seawater samples.

From July 11 – August 8, 2024, 4 CSSF team members piloted the CCGS Amundsen’s ROV, ASTRID (Amundsen Science Technology for Remote Innovation and Discoveries) in the Labrador Sea as part of contract work to support Amundsen Science.

Leg 2a of the 2024 Amundsen Expedition was led by the Nunatsiavut Government in collaboration with Fisheries and Oceans Canada and several other research programs led by other organisations, including ArcticFish, Arctic Kelp, Avaaforfish, Natural Resources Canada’s marine mapping programs, the Northern Contaminants Program and the Ocean Frontier Institute’s Sustainable Nunatsiavut Futures program. Leg 2a took place along coastal Labrador, as well as in the Labrador Sea and Baffin Bay, Canada. Two programs required the use of an ROV during Leg 2a, 1) the Imappivut Initiative and 2) DFO’s Benthic Refuges Program. For these, the science objectives were to further study previously identified biodiversity hot spots and investigate new biodiversity hot spots, with the guidance of local Nunatsiavut knowledge, as well as to characterize benthic habitats within or adjacent to Marine Refuges.

From March 18 – May 10, 2023, 6 CSSF team members supported the Korea Institute of Ocean Science and Technology (KIOST), which works in partnership with the International Seabed Authority (ISA). The science team’s focus was to conduct research on the hydrothermal vents of the Central Indian Ridge. There were two main objectives for this expedition: 1) to understand the environmental characteristics of the hydrothermal vents and analyze the structure and function of the surrounding ecosystem, as well as 2) to investigate the characteristics of mineral resources formed by hydrothermal activity. The expedition focused on geology but also included some biology. Tasks that required ROPOS included collection of video footage along with biological and bedrock samples.

From August 12 – September 2, 2024, 6 CSSF team members supported Fisheries and Oceans Canada’s Pacific Region (DFO Pacific) aboard the CCGS John P. Tully for the Northeast Pacific Deep-sea Exploration Project’s (NEPDEP) 2024 expedition. The focus of this expedition was to discover, explore and monitor deep-sea ecosystems. Specifically, this included ‘Ecologically and Biologically Significant Areas’ in existing, planned and potential marine protected areas (MPAs). In addition to members of DFO, ship- and shore-based participants included scientists and professionals from the British Broadcasting Corporation (BBC), Canadian BioGenome Project, Council of the Haida Nation, Hakai Institute, NOAA Fisheries, Nuu-chah-nulth Tribal Council, Royal BC Museum, University of Calgary, University of Gothenburg, University of Victoria and University of Washington.
