COR1503 Expedition in the Old Harry influence zone of the Gulf of St. Lawrence: marine geology data, sediment characterization

COR1503 Expedition of the Old Harry project took place from June 8th to 20th 2015 on board the research ship (R/V) Coriolis II. The general objective was to perform detailed geophysical surveys (high-resolution multibeam bathymetry and seismic profiles) and to collect different types of sediment samples, in order to evaluate the potential risks of oil and gas exploitation on the marine ecosystem of the Gulf of St. Lawrence (Old Harry Influence Area). This dataset includes sample locations and high-resolution images of the cores (photo). Different sediment properties were analyzed, such as: physical properties (spectrophotometry [L* a* b*, RGB, XYZ, Munsell color], gamma density, P-wave velocity and amplitude, fractional porosity, resistivity, impedance and grain-size), magnetic properties (magnetic susceptibility) and chemical properties (14C isotopic dating).
