Scientists from Croatian geological survey participate in oceanographic scientific cruise in Adriatic sea named Ad-APTA on research vessel „RV Poseidon“ (cruise POS514)

 

 

Scientists from HGI-CGS participate in a geological and oceanographic scientific cruise in the Adriatic Sea onboard RV „Poseidon“ (Helmholtz-Zentrum für Ozeanforschung Kiel). Cruise will last for 21 days in period from 27th of May until 16th June. This cruise is a joint project that comprises participation of four groups of scientists from Germany, Austria, Croatia and Italy. Cruise is a part of a joint scientific project entitled „Micropaleontology, Actuopaleontology, and Environmental Baseline Study of the Holocene to latest Pleistocene in the northern and eastern Adriatic Sea basin“ (Code name: APTA: Actuo-Paleontology Trans-Adriatic). This cruise is organized by the chief scientist Prof. Dr. Hartmut Schulz and Prof. Dr. James Nebelsick from Fachbereich Geowissenschaften, Tübingen University, together with Prof. Dr. Petra Heinz, Marine Palaeoecosystems, micropalaeontology, Institut für Paläontologie, Prof. dr. Martin Zuschin, Environmental Palaeontology, Invertebrate Palaeontology, University of Vienna, dr. Slobodan Miko, Croatian geological survey and dr. Vanessa Rossana Cardin, Oceanography Division-Experimental Oceanigraphy Group OGS-Trieste.

There will be 11 scientists on board, including dr. Nikolina Ilijanić i dr. Ozren Hasan from HGI-CGS as team members of HRZZ (Croatian Science Foundation) funded project Lost Lake Landscapes of the Eastern Adriatic Shelf (LoLADRIA). A purpose of this cruise is to collect samples of water and sediments for micropaleontological and sedimentological studies to determine baseline values analysing marine Holocene and Pleistocene sediments of northern and eastern Adriatic. At the same time, hydrographic measurements using CTD probe will be performed, as well as collection of samples using plankton nets and water filtration. Sediment sampling includes use of Van Veen grab, Frahm corer, box corer, multi corer and gravity corer with length up to 10 m. Scientists of HGI-CGS are responsible for operating the gravity corer, multicorer and Frahm corer. Since studies in Ad-APTA are compatible with the aims of LoLADRIA project, sedimentological, geochemical and mineralogical analysis of collected sediments will be made in Croatian geological survey and University of Tübingen, which will result in published joint scientific papers. Also, collected data will be included in Geological map of the Croatian sea floor, a project led by Croatian geological survey and Croatian Hydrographic institute.

More details about the cruise can be found on the web page of LoLADRIA project (https://loladria.wordpress.com/).
