The data are time-series of in-situ pore pressure and temperature measurements from two piezometers deployed in the Sea of Marmara within the EU-funded MARSITE Programme. Instruments were deployed in September 2013 during the MARMARA-13 Cruise of R/V URANIA on October 2013 and recovered on November 2014 during the MARSITECRUISE of R/V Pourquoi pas?. Each free-fall piezometers (developed by Ifremer) consists in a sediment-piercing lance of 60 mm diameter, ballasted with lead weights (>1000 kg), equipped with differential pore pressure and temperature sensors, welded at 6 depth-levels, having an accuracy of ±0.5 kPa and 0.05°C respectively.
