    Description: We present here paleomagnetic and magnetic anisotropy data from discrete samples collected in the middle Eocene to early Miocene sediment recovered in International Ocean Discovery Program (IODP) Sites U1507 and U1511 (Expedition 371, Tasman Sea, 27 July to 26 September 2017). Data consists of three tables (Table S2, S3, S4). Table S2 contains the paleomagnetic directions from discrete specimens collected in both Hole U1507B and Hole U1511B. The samples were measured for their paleomagnetic signal at the University of Bremen (Germany) between 2019 and 2021. Paleomagnetic inclinations are listed before and after correction for inclination shallowing. Table S3 contains the anisotropy of magnetic susceptibility (AMS) of representative specimens from Hole U1507B. Table S4 contains the anisotropy of anhysteretic remanent magnetization (AARM) of representative specimens from Hole U1507B. Both the AMS and AARM data of tables S3 and S4 were acquired at the University of Turin (Italy) between 2020 and 2021. These data were used for determining the absolute paleolatitude of northern Zealandia between the middle Eocene and the early Miocene (Dallanave et al., 2022; doi:10.1029/2022JB024736).

    Description: In the framework of the project EXTREMEVENT, we measured the topographic and granulometric attributes of coastal boulders in various places in the Noth Atlantic : the coasts of the Reykjanes Peninsula (southwestern Iceland), the coasts of Brittany (western France). This dataset gathers these attributes as follow: - the date, the country, the region, and a site identifier; - the type of boulder (CTB = cliff-top boulder; SPB = supratidal platform boulder); - the X, Y and Z positions, measured with a differential global positioning system (DGPS) in real-time kinematic (RTK) mode (initially measured in a local coordinate reference system (EPSG:5326 in Iceland, EPSG:2154 in France) and then converted to EPSG:4326; altitudes are given in meters above mean sea level); - the length of the A (longest axis), B (intermediate axis) and C (shortest axis) axes of the boulders, measured with a measuring tape; - the inland distance, corresponding to the distance of each boulder's location from the nearest position of the highest astronomical tide level; - the density of the rock in which the boulders are made.
