Deltas are at the transition between fluvial and marine sedimentary environments where sediment density flows are often triggered during high river discharge events, forming submarine channels and sediment waves. On wave‐influenced deltas, longshore currents are particularly efficient at transporting sediment alongshore, reducing the likelihood of...

The St. Lawrence Estuary in eastern Canada is a large coastal ecosystem of about 10,850 km2 that is affected by the presence of sea ice in winter. The suspended particulate matter (SPM) dynamics in this estuary are strongly influenced by winds, tides, river runoff, and coastal jets. One of the SPM properties is the particle size distribution (PSD)...

The reduction in Arctic summer sea-ice cover observed over the last decades allows for new shipping routes, new fishing grounds and cruise tourism opportunities. Thus, as part of the Arctic Blue Economy strategy, the shipping, oil and gas exploration, mining, fisheries and tourism sectors have been identified as areas of important potential economic growth in the Canadian Arctic. The integration of multiple spatial datasets from the marine environment is therefore needed for a sustainable management of offshore resources in the Canadian Arctic. Combining acoustic mapping of the seabed relief, surface sediment composition and subsurface sediment records can provide invaluable information to understand the geological processes shaping the seafloor, to assess natural hazards and coastal habitats and to document the evolution of sea surface conditions, as well as aid the development of the Arctic Blue Economy. In this context, the overall objectives of this cutting-edge Arctic research program are to 1) perform detailed mapping of the Arctic CanadaSeafloor and adjacent coastal areas as an aid in understanding potential marine geohazards, minimize potential hazards to navigation, establish seafloor habitat characteristics, and improve the bottom boundary of Arctic Ocean modelling, 2) better document the age and origin of Canada’s Arctic seafloor using a multidisciplinary approach that contributes to the development of a robust geological and paleoenvironmental framework, and 3) develop data dissemination tools tolink the acoustic data products with the Arctic seafloor mapping user communities. Taken as a whole, this research program will update and significantly improve the existing seafloor mapping coverage, provide foundational seafloor characterization for habitat and ocean modelling, improve navigation safety, and unravel the fundamental processes controlling the sediment and climate dynamics across the entire marine Arctic Canada. Finally, this research programwill provide a dynamic training environment for highly qualified personnel, with access to expertize in various fields of ocean mapping and marine geology, and hands-on training on ship-based seafloor mapping and coring operations.

In this project, we raised the question of whether the Nd isotope composition of bottom seawater in the EGSL could be reliably obtained from the bulk sediments in order to elucidate sources and bottom water mass mixing in this estuarine environment. To resolve this query, we investigated and compared the concentrations in rare earth elements (REEs) and the εNd and 87Sr/86Sr signatures from a set of seawater samples and authigenic (leached Fe-Mn oxyhydroxides) and detrital fractions of bulk sediment core-tops collected in the EGSL and continental shelf off southeastern Canada. To corroborate the reliability of our leaching method, we examine REE patterns and 87Sr/86Sr ratios to assess the absence of detrital contributions to the leaching solutions and to support the seawater origin of the εNd signatures in the bulk sediment leachates. In addition, detrital εNd, 87Sr/86Sr, and REE records of surface sediments are used to identify different source areas and transport pathways of terrigenous material in eastern Canada.
