Multibeam Bathymetry, Acoustic Doppler Current Profiler, and Sediment Core Data from the Pointe-des-Monts Underwater Canyon System, St. Lawrence Estuary
This dataset includes multibeam bathymetric maps, time-evolution bathymetric profiles of submarine canyon slopes calculated from 3 different bathymetric maps (2015, 2020 and, 2022), downward Acoustic Doppler Current Profiler and CTD time series from October 2020 to Oct 2022, CTD profiles around Pointe-des-Monts, high resolution photography, radiography and laminography of short sediment cores, and magnetic susceptibility, D50 and sorting along each sediment core sampled offshore Pointe-des-Monts. The objective of this work is to determine the recurrence of turbidites observed in the short sediment cores in order to determine if they reflect turbidity current activity within the Pointe-des-Monts submarine canyon system. The second objective is to determine the influence of bottom currents on the sedimentary deposits record. This project was originally funded by Réseau Québec maritime (RQM) and Marine Environmental Observation, Prediction, and Response Network (MEOPAR).
The ADCP dataset is currently undergoing standardization. An ERDDAP version will be available soon.
