Technical Report of the IFIGENIA cruise with the R/V Gaia Blu (Tyrrhenian back-arc basin, Mediterranean Sea)
Abstract:
The Ifigenia cruise, conducted from August 9 to 23, 2023, aboard the Research Vessel (R/V) Gaia Blu, a key infrastructure of the National Research Council (CNR), represents a multidisciplinary effort to explore the geological and biological dynamics along back-arc basin regions. The Ifigenia project focuses on the central-northern Tyrrhenian basin, a natural laboratory to investigate the marine geological and biological biodiversity. The cruise covered 1,500 nautical miles and utilized advanced equipment to collect multidisciplinary data. The cruise was carried out in two parts. The primary focus of the first Leg was the acquisition of new geophysical data: 1) high-resolution multibeam data for producing a new detailed bathymetric map; 2) sub-bottom profiler chirp data to analyze the nature of the uppermost sediment layers beneath the seafloor; 3) magnetic data for creating a reduced-to-pole magnetic anomaly map. The second Leg focused on sampling operations during the day and continued geophysical data acquisition during nighttime. Seafloor sediment sampling was conducted using an oceanic box corer and a gravity corer in order to characterize sediments and benthic communities. The CTD-Rosette system was used to measure the chemical-physical parameters of the water column and to collect water samples for environmental DNA analysis. Furthermore, a central element of the cruise was science communication. Specialized personnel from CNR documented the cruise, producing a scientific documentary showcasing the collaborative efforts of scientific teams aboard the R/V Gaia Blu. This initiative aimed to provide insights into the multidisciplinary nature of oceanographic research and its societal relevance.
