Final conference of the LoLADRIA project “Submerged Pleistocene landscapes of the Adriatic Sea“

This year the 5th Regional Meeting hosts the Final conference of the LoLADRIA project “Submerged Pleistocene landscapes of the Adriatic Sea“, organized by Croatian Geological Survey. The meeting will take place in Starigrad-Paklenica, from 9th to 10th November 2017.

This topic intends to uncover submerged landscapes in relation to sea level change.  Global sea level during the last 500,000 years oscillated between 120-130 m below present sea level and 5-10 m above present sea level. Since the sea was lower than at present for most of the last million years, large areas of land were exposed and were occupied by terrestrial vegetation, animals, and early humans. An assessment of Holocene sediment thickness will be examined along the Eastern Adriatic coast and the position of former coastlines at different time-frames including the Last Glacial Maximum. Submerged landscape features (landforms and deposits) and palaeoenvironmental indicators can be classified through an appraisal of existing records (e.g. bathymetry maps, geophysical data, sediment cores) and include:

  • coastal (shorelines, lagoons, beaches, estuaries etc.),
  • riverine (valleys, channels, deltas, terraces etc.),
  • subaerial (aeolian, rough or flat terrains, karst, volcanic etc.),
  • water points (groundwater discharge points, freshwater lakes etc.), and
  • archaeological data.

The conference aims to bring together sedimentologists, geochemists, mineralogists, geomorphologists and paleontologists with interests in interdisciplinary research of high resolution paleoenvironmental reconstructions of submerged karstic depressions during the Late Pleistocene and Holocene sea level rise. The answer lies beneath the sea in the mud and sediments of the continental shelf.

MOPP-MEDFLOOD workshop in Sardinia

In the period between 24-27 September 2017 team memeber Dea Brunović participated in second MOPP-MEDFLOOD workshop, held in Sardinia. MOPP-MEDFLOOD is INQUA funded project that gathers scientific community working on the sea-level changes during the Late Pleistocene and Holocene in the Mediterranean region. This year, workshop offered field perspective on different sea-level indicators that are present along coastline of Sardinia. Participants were able to observe geological and archeological indicators of sea-level change, such as beachrocks, roman pier, archaeological settlements, salt-marshes, dunes and coastal lagoons. Scientists with different research background discussed on the field numerous advantages and disadvantages of using different sea-level indicators for reconstruction of Late Pleistocene and Holocene sea-level changes. Worshop also included visit to Nuragic archeological settlement that dates back to the Bronze Age. Last day of workshop, organized at City Hall of Palau, was dedicated to presentations of young researchers. Sessions included presentations on paleoenvironmental reconstructions, archeological indicators of sea-level change and modelling of paleo-processes.

Poseidon Cruise POS514

Team members Ozren Hasan and Nikolina Ilijanić are participating on the scientific cruise in the Adriatic Sea on research vessel (RV) Poseidon (Kiel, Germany). Cruise started from Heraklion on Crete on 27th of May and will end on 16th June in Dubrovnik. They are experiencing the off-shore life on a 60 m-ship, which includes drilling with gravity corer (3, 5 or 8 m core tube), sampling of the sea-surface sediments using multi corer, Frahm corer, box corer and Van Veen grab corer, sampling of the plankton at various depth and measurements of conductivity, temperature, oxygen and fluorescence of the sea water column. The cruise 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) is organized by the chief scientist Hartmut Schulz from the University of Tübingen, in coordination with Slobodan Miko from the Croatian Geological Survey. The 21 days-long cruise is financed by the German Research Foundation (DFG). The scientific crew make James Nebelsick and Tobias Grun from University of Tübingen, Petra Heinz, Julia Wukovits, Patrick Bukenberger and Martin Zuschin from Vienna University, Guiseppe Siena and Nydia Catalina Reyes Suarez from National Institute of Oceanography in Trieste and Ozren Hasan and Nikolina Ilijanić from Croatian Geological Survey.

CTD (Coductivity Temperature Depth) is deployed routinely at most stations at variable depths, it has a bulk flourescence sensor and bottles for water sampling. MultiNet (5 nets) is also deployed at variable depths (ie 100 and 700 m) for plankton sampling using 100 and 63 µm nets. Samples are immediately deep frozen and stored.

Ozren Hasan and Nikolina Ilijanić are responsible for operating the Gravity Corer (GC), heavy instrument that includes heavy work setting up of variable 3 and 5 m core tubes up to 10 m total length. Cores are immediately cut into 1m-sections, capped, sealed, labeled and stored/cooled to be opened in Tübingen. Short cores (< 50 cm) are collected using the Multi Corer (MUC) able to collect as much as 8 cores in the same time. Only the best are photographed, sliced by 1 or 2 cm interval and packed into plastic bags. On selected sites best sediment surface samples are collected (0-1, 1-2 cm) and also taken for incubation foraminifera experiments on board. Frahm Corer is used to collect up to 100 cm-long cores in shallower depths, the cores are photographed, sliced and packed in plastic bags. Van Veen Grab Corer is deployed mostly at shallow depths, robust, effective and it is used for instance surface and shallow benthos sieved/washed. Box Corer (BC) is used to collect up to 20 cm-long cores with well preserved sediment surface. Cores are photographed and sliced, than packed into plastic bags.

We wish them succesfull cruise, nice weather and lots of cores and sediments from the Adriatic Sea!

The Koločep kanal and Elaphiti islands/Mljet Island marine geophysical survey

In the early 2016, began the preparation for the research of the new sites in LoLADRIA project – southern Dalmatia. The location is the huge canal in Dubrovnik archipelago, Koločepski kanal. It is surrounded by the islands Lopud, Koločep and Šipan (Elaphiti islands;, and several small islands toward Pelješac peninsula (Olipa and Jakljan islands).

This elongate submerged karst depression is characterized by the numerous submarine springs with  groundwater flowing from sinkholes (ponors) along the Trebišnjica river in Bosnia and Herzegovina. During the late Pleistocene  freshwater from the karst springs filled the silled basin (-50 m), hopefully forming a lake (it’s what we are looking for). At the end of April 2016, our project members from the Laboratory of Marine Geology and Physical Oceanography , University of Patras, (George, Dimitris, Maria, Nikos and Xenofon) and HGI_CGS (Slobodan, Ozren and Nikolina) spent one week surveying Koločepski kanal and the submerged river valley between Mljet island and Olipa island. Research vessel, Božja providnost II, was struggling with the strong bura winds during the geophysical survey (armed with an 3.5 kHz ORE Pinger with 4 transducers, Geopulse transceiver/receiver, Digital Acquisition System Triton Imaging Inc, and side scan sonar system: G&G. 272 TD towfish ),  but the results were outstanding. Very deep penetration of sub-bottom profiler allowed identification of 50 m of sediment sequences in the kanal. Fascinating sediment structures, sand plateaus, tectonics, river valleys  and erosion events were revealed. This research will give detail geomorphological evidence for reconstruction of paleolandscape during the Late Pleistocene and the last deglaciation. We will start coring in September 2016.
