Abstract:
Research cruise M196 took place during 05.12.2023 - 27.12.2023, starting from Piraeus (Greece) and ending in Limassol (Cyprus) in the Mediterranean Sea (Jegen et al., 2024). Main working area was the Gulf of Corinth. The main focus while conducting 3 towed Video-CTD (CTD-V) services during M196 cruise on 17th of December 2023 was to monitor bottom water oceanographic conditions and seafloor characteristics within the nearshore Egio fault area at stations M196-35 and -36 in the Gulf of Corinth. The aim was to search for evidence of OFG and related submarine groundwater discharge by measuring salinity changes in bottom water, and/or observing e.g. shimmering water and benthic community changes at the seafloor. In total 2h 44 min of near-bottom CTD data and video streams were recorded.
