Using 15 years of high-frequency data from the European Multidisciplinary Seafloor and water column Observatory (EMSO) South Adriatic Regional Facility (moorings E2M3A, BB and FF), the occurrence of gravity currents in the deep South Adriatic Pit (SAP) is investigated. Six different criteria were used for the investigation of gravity currents. Four gravity current events were reported at the bottom of the SAP, in 2012, 2017, 2018 and 2022 (bottom mixing years). These events took place from mid-February to June and are followed by a relaxation phase that lasts a few months. While the 2012 gravity current event was driven by temperature, salinity played a governing role in the other years.

Abstract
Using 15 years of high-frequency data from the European Multidisciplinary Seafloor and water column Observatory (EMSO) South Adriatic Regional Facility (moorings E2M3A, BB and FF), the occurrence of gravity currents in the deep South Adriatic Pit (SAP) is investigated. Six different criteria were used for the investigation of gravity currents. Four gravity current events were reported at the bottom of the SAP, in 2012, 2017, 2018 and 2022 (bottom mixing years). These events took place from mid-February to June and are followed by a relaxation phase that lasts a few months. While the 2012 gravity current event was driven by temperature, salinity played a governing role in the other years.Pubblicazioni consigliate
