| Summary: | Sedimentological and geochemical data of sediment cores collected from Aurora Vent Field (82.5N) in the Fram Strait during HACON21 expedition. The sediment cores were collected via gravity coring (GC), multicoring (MC), and ROV-guided blade coring (BC) from the R/V Kronsprins Hakon. Gravity coring was conducted with a 6 m long steel barrel deployed which contains a PVC liner with an inner diameter of 10 cm. Here, we report the results for GC-191 (215 cm) and GC-193 (255 cm). These sites are located at various distances from the active vents. We used a KC Denmark DK8000 multicorer hosting up to six transparent plastic liners with a diameter of 10 cm and length of 70 cm. We report the results from surface (0-5 cm) sediment of the multicore MC-148 (25 cm). ROV-guided coring operations at the vent site were conducted with the ROV Aurora, owned and operated by REV Ocean (Norway). The blade cores are picked up from a compartment on the ROV by its manipulator arm and pushed into the seabed. Blade cores can reach a maximum depth of 32 cm below sea floor, have a thickness of 10 cm and a width of 25 cm. Here we report the data from the upper 5 cm of blade cores BlaC-01 (28 cm) and BlaC-03 (17 cm). Sampling locations are reported in the separate the Core_location.txt file.
