“…The primary contributing factor involves the installation of novel groynes, coinciding with a particularly severe storm event shortly after their construction. Erosion that occurs at the end of the groyne group is well known in the literature [42,43]. Figure 20, a photograph taken on 21 May 2021, during the LiDAR measurement, clearly shows the sea side effect associated with the intensification of erosion processes at the end of the newly constructed groynes.…”

Coastal erosion is a pervasive global phenomenon, exemplified by the Hel Peninsula situated in the Gulf of Gdańsk, the southern Baltic Sea. The geological constitution of the Hel Peninsula, characterized by sandy and loosely consolidated material, predisposes its coastal zones to continual morphological changes. The peninsula’s limited width and elevation exacerbate shoreline erosion, particularly during periods of heightened storm activity. This study scrutinizes the effectiveness of coastal nourishment interventions, with a specific focus on segments influenced by the Władysławowo port and the Kuźnica vicinity, over several years. This specific section of the coast serves as a significant case study due to its role as a transit zone for sand transport along the whole peninsula. Protective measures, including shore nourishments and coastal groynes, aim to mitigate erosion impacts. Utilizing Airborne Laser Scanning (ALS) data spanning from 2008 to 2022, erosion dynamics were analyzed. The analysis reveals significant erosion patterns coinciding with the frequency and volume of nourishment material deposition, particularly evident in heavily nourished areas proximate to Władysławowo and Kuźnica. Despite persistent monitoring endeavors, persistent erosive trends pose imminent threats to Kuźnica’s infrastructure, necessitating further research into the efficacy of implemented coastal protection measures.

The article presents the accessibility conditions for carrying out research work for an exemplary site in the southern Baltic Sea region. The basic parameter of the state of the marine environment was the significant wave height determined at a frequency of one hour based on the ERA 5 model data covering the period between 1940 and 2022. A statistical analysis of the variability of this height on a monthly basis, taking into account its conversion into the time of potential availability in conditions enabling research, showed its strong seasonal variability in the form of differences in the number of hours that can be used for operating purposes. This number, depending on the research vessel capabilities, may even be an order of magnitude higher in the summer months than in winter. Additionally, it was found that the variability of the significant wave height has not changed substantially over the last 82 years.
