“…The lack of halite (NaCl), the scarcity of calcite in the XRD analysis, the probable iron oxide concretions and the terrestrial gastropod fit better to colluvial sediments than to marine deposits. These observations are in strong contrast with the data from five sediment cores from water covered karst dolines from the eastern side of the Lošinj channel (Brunović et al, 2019, fig. 1c), all of which contained halite and all showed a (restricted) foraminiferal fauna, at least in their upper levels (Brunović et al, 2019).…”

“…According to Faivre et al (2010) and Antonioli et al (2007) the local sea-level rise since Roman time was about 1.0-1.5 m or 1.5 m, respectively. During sea-level rise, some of the dolines were completely flooded by the sea, some of them were partly inundated while others are still slightly above the present day sea-level (Brunović et al, 2019). According to our interpretations, the investigated doline northeast of Osor (Fig.…”

“…The local sea-level rise in the western Mediterranean during the last 10,000 years has been reviewed recently by Vacchi et al (2016). Brunović et al (2019) used cores from submerged dolines in the Lošinj channel to reconstruct -3 m for the local sea-level at around 4,300 BCE. Faber (1980) estimates an almost 2 m lower local as bulk samples, while ED15/Osor/1 was sieved at <63 μm to remove coarse limestone particles.…”

We combine geoarchaeological investigations with high-resolution airborne laser scanning (ALS) topographic and airborne laser bathymetric (ALB) measurements to reassess the topography of the Roman city of Apsorus (modern Osor, northeastern Adriatic Sea, Croatia), which has generally been interpreted as important nodal point of Roman maritime traffic. Apsorus is located at the isthmus connecting Cres and Lošinj islands, which is 90 m wide at the narrowest part and dissected by a canal of supposed Roman age. A conspicuous low-lying wetland north of the city has been suggested to be a former sea passage and harbour area. Geoarchaeological coring, sedimentological analysis and radiocarbon dating suggest that this depression was already silted up with terrestrial sediments some 6,000 years ago and, especially in combination with the lower sea-level at that time, could not have been a Roman harbour. The combination of the ALS/ALB topographic data with lower sea-levels reconstructed for the Roman period challenges the traditional view which places ancient Osor on a small island and allows for new interpretations of the accessibility of Osor by sea.

Purpose This work highlights the sedimentary characteristics and the role of submarine sulfur-rich karstic springs in the distribution of benthic foraminifera in the northern part of the Adriatic Sea (Bay of Koper). Little is known about how local conditions such as temperature and sulfur bursts may influence sediment properties, benthic habitat variability, and composition of foraminiferal assemblages. Here we compare the distribution of total and living benthic assemblages in surface sediment samples collected from a funnel-shaped depression created by submarine sulfur springs. Materials and methods Sampling was performed at water depths between 24.6 and 32.2 m in fine-grained sandy silt to silty sand (partially washed). Sedimentological, mineralogical, and geochemical analyses of the sediment were carried out and the distribution of benthic foraminifera living around the springs was studied. Results and discussion In general, sediment characteristics (i.e., mineralogical, geochemical, and organic content) around the sulfur springs do not show prominent deviations from the marine surface sediment of the area; however, some differences exist among depressions of different depths. Deeper depressions in the lower parts probably extend to older continental sediments of Late Pleistocene age with alluvial features, while shallower depressions were formed entirely in Holocene marine sediments typical of a wider area. Only one of the five samples (M05) contained living foraminifera in sufficient abundance for biocenosis research. The benthic foraminiferal assemblages of moderate diversity are composed of opportunistic species. Elphidium translucens, Ammonia ex gr. tepida, Haynesina depressula, and Porosononion granosum dominate, while A. neobeccarii, Reussella spinulosa, and Textularia bocki are subordinate. Conclusions The distribution and diversity of foraminifera in the sediment near sulfur springs can be explained by several factors and their interactions. The intensity of the spring discharge affects the mixing/oxygenation of the sediment, the shape of spring depressions, and the granulometry of the coarser sediment around the springs. Sediment characteristics indicate different types of sediment origin. This is related to and can be explained by the depth of spring depressions.
