“…This slumping of the system is a characteristic feature in the Kosi Bay system and is thought to have formed by margin instability associated with wave reworking of lagoonal and lacustrine shorelines (Wright et al, 1999;Cooper et al, 2012). These slump packages have some similarities to those typically formed on delta fronts of bayhead deltas, however, they are different from delta front processes (Rucińska-Zjadacz, and Wróblewski, 2018) where sediment delivery to the steep margins usually occurs through fluvial discharge (e.g. Dladla et al, 2021).…”

“…In general, the seabed is inclined toward the north-east. The coastal shallows stretch along the Hel Peninsula, forming underwater "shelves" with a depth ranging from 0.5 m to about 4 m and a width of 1000-1200 m. The boundary of the shallows is clearly visible in the form of a sharp increase in the seabed inclination, which steeply descends to a depth of 40-50 m. The maximum slope of the seabed is located at the tip of the Hel Peninsula and ranges from 5 to 7 o (average) to a maximum of 20 o Rucińska-Zjadacz & Wróblewski 2018). Although Puck Bay covers a relatively small area (359 km 2 ), it is a very diverse water region in terms of both seabed configuration and lithodynamic conditions.…”

Puck Bay is an unusual and thus interesting coastal water region, as it combines two different environments – a lagoon and the sea. They differ from each other in their seabed morphology, salinity, dynamics and water exchange. Their common elements are the extensive shallows and the vicinity of the Hel Peninsula. The shallows of Puck Bay have developed at various stages of its evolution, which began several thousand years ago and continues to this day. They have been shaped by varying morphogenetic factors resulting from changes in sea level and accompanying evolution phases of sand barriers, e.g. washover fans, as well as the intensity and directions of sediment transport. At present, the shallows cover more than 35% of the seabed area and are influenced by hydrodynamic factors and availability of sediments. The study area was divided into five fields, taking into account morphological and genetic criteria as well as recent hydrodynamic conditions. This study provides an updated map with classification and distribution of surface sediments and describes grain size parameters for sediment samples collected in the selected fields. Based on a comprehensive assessment of grain size parameters, lithodynamic equilibrium zones were determined and areas of sediment deposition and redeposition were identified.

“…Correct maps of the seabed can be achieved by groundtruthing in the form of direct seabed video observations, sediment sampling, and sediment sample analyses [1,3,8,9]. High-resolution sub-bottom profiles are used as an additional tool for the better interpretation of mapped units and allow insight into the third dimension of the gathered data [10][11][12][13][14][15].…”

The upper part of the Krka River estuary and Prokljan Lake are a specific example of a well-stratified estuarine environment in a submerged river canyon. Here, we reconstructed the geomorphological evolution of the area and classified the data gathered in the study, integrating multibeam echosounder data, backscatter echosounder data, side-scan sonar morpho-bathymetric surveys, and acoustic sub-bottom profiling, with the addition of ground-truthing and sediment analyses. This led to the successful classification of the bottom sediments using the object-based image analysis method. Additional inputs to the multibeam echosounder data improved the segmentation of the seafloor classification, geology, and morphology of the surveyed area. This study uncovered and precisely defined distinct geomorphological features, specifically submerged tufa barriers and carbonate mounds active during the Holocene warm periods, analogous to recent tufa barriers that still exist and grow in the upstream part of the Krka River. Fine-grained sediments, classified as estuarine sediments, hold more organic carbon than coarse-grained sediments sampled on barriers. A good correlation of organic carbon with silt sediments allowed the construction of a prediction map for marine sedimentary carbon in this estuarine/lake environment using multibeam echosounder data. Our findings highlight the importance of additional inputs to multibeam echosounder data to achieve the most accurate results.
