Mission COR1503 dans la zone d'influence d'Old Harry du golfe du Saint-Laurent : données de géologie marine, caractérisation des sédiments

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).

COR1503 老哈利项目（Old Harry project）科考航次于2015年6月8日至20日在“科里奥利二世号”（R/V Coriolis II）研究船上实施。本次科考的总体目标是开展详细的地球物理勘探（高分辨率多波束测深与地震剖面测量），并采集多类沉积物样品，以评估圣劳伦斯湾（老哈利影响海域）油气开发对海洋生态系统的潜在风险。本数据集包含沉积物岩芯的采样点位与高分辨率图像（照片）。研究团队对多种沉积物属性开展了分析，具体包括：物理属性（分光光度法测定的L*a*b*色空间、RGB、XYZ、孟塞尔（Munsell）颜色，伽马密度、纵波速度与振幅、孔隙度分数、电阻率、阻抗与粒度）、磁学属性（磁化率）以及化学属性（14C同位素测年）。
