This database comprises piezometer pore-pressure and temperature data, analyses from Calypso sediment cores (grain sizes and logs) and results from geotechnical tests (index tests and oedometer tests), used for the study of seepage systems along the Vestnesa Ridge, in the eastern Fram Strait. The data were collected over 2 research expeditions to the area. The reports for each of the expeditions can be accessed via Septentrio (https://septentrio.uit.no/index.php/cage): - CAGE20-6 cruise report (https://doi.org/10.7557/cage.6918) -CAGE19-3 cruise report (https://doi.org/10.7557/cage.6911) In-situ pore fluid pressure (P) and temperature (T) were measured using the Ifremer piezometer which consists of a cable-deployed tool equipped with a sediment lance of 60 mm diameter carrying differential pore pressure (i.e., pore pressures in excess of hydrostatic pressures or excess pore pressure) and temperature sensors ( e.g., In situ equilibrium pore-water pressures derived from partial piezoprobe dissipation tests in ...
