The studies conducted indicate that these properties in brackish areas differ significantly in re- spect of electrolytic conductivity and chloride content from waters occurring in areas not occupied by halophyte communities. Based on the results obtained, it was found that in the studied coastal zone the occurrence of salt grassland ecosystems is associated with water conductivity above 2,000 PScm-1 and chloride content above 600 mgdm-3. These values are many times higher than average values for typical inland waters in the Pomerania area, which clearly indicates the dominant role of the brackish water inflow from the Baltic Sea in shaping the environmental conditions for the occurrence of such ecosystems.

This differentiation depends both on the local conditions of seawater intrusion inland and on the intensity of inland surface and ground water inflows. In the case of cliff shores, the results of soil and habitat identification and their relationships with the dynamics of morphodynamic processes (abrasion, slope processes) were summarised. On this basis, the characteristics of the main types of cliff ecosystems (initial grassland communities, scrub with sea buckthorns, low stemmed scrub and sycamore forests) were presented. The results indicate that the varying intensity of the slope processes significantly affects the diversity of soil types and soil properties, including the presence of calcium carbonate and the high pH values in active cliffs. These features, among others, discriminate the cliff ecosystems commonly found in the Pomerania region. .H\ZRUGV: saline waters, saline ecosystems, halophytes, coastal habitats, cliff ecosystems, Baltic Sea. ,QWURGXFWLRQ of coasts, as well as in the formation of specific hydrologi- cal and hydrochemical conditions associated with ingresses The shore area is characterized by a specific nature, re- of sea waters into the land area.

Growing shipping traffic increases the likelihood of collisions. A quantitative analysis of the impact of fishing vessel traffic streams on streams of merchant vessel traffic aims to identify areas of intense traffic of this type and to assess the potential risks. The identification of intersections of fishing vessel routes and merchant shipping traffic allows us to identify spots of potential collisions. The analysis made use of the IALA IWRAP Mk2 program and AIS data collected from April 1, 2013 to March 31, 2014.

Therefore, hydrological conditions were the most important factors controlling the inflow of Hg to the sea. The second most important Hg source in the Gulf was atmospheric deposition, which transported seven times smaller load than rivers. The Hg wet deposition dominated in the warm season, while during the heating season the predominant was dry deposition of mercury. The Hg source, which should not be neglected during the creation of the mass balance of Hg in aquatic ecosystems, was the coastal erosion. In the Gulf of Gdańsk, it accounts for 6% of the Hg load reaching the sea. The main sink of Hg was bottom sediments. Other important processes that reduced the Hg load in the Gulf water were re- emission of Hg to the atmosphere and export of this metal to the Baltic Proper. The mass balance of mercury in the Gulf of Gdańsk indicated that a larger load of this metal flowed into the Gulf than left it.

KEYWORDS Monosaccharides Baltic Sea Seawater Waldemar Grzybowski Agnieszka Maksymiuk Institute of Oceanography, University of Gdańsk, al. Marszałka Piłsudskiego 46, PL–81–378, Gdynia, Poland; e-mail: [email protected] Manuscript received 20 February 2001, reviewed 23 April 2001, accepted 9 May 2001. Abstract The concentration of monosaccharides in samples collected in the Gulf of Gdańsk area was determined in water filtered through ∼0.8 µm pore size filters. Seawater concentrations ranged from about 0.2 to 1.1 mg C dm−3, the highest values being detected at the mouth of the river Vistula. Seasonality was detectable in the data distribution; the majority of autumn values lay within the 0.2–0.4 range while concentrations in the spring samples were higher and the values more widely scattered. Measurements of monosaccharide concentrations at selected points during the whole observation period showed that values increased from spring to autumn as much as 5-fold. Concomitant analyses in Vistula river water yielded concentrations from 0.4 to 1.2 mg C dm−3. These latter values were all higher than those recorded in seawater in the corresponding months. 1. Introduction Saccharides comprise the largest class of chemically identified cons- tituents of dissolved organic matter (DOM) in seawater (Williams 1975). Their estimated proportion in the dissolved organic carbon (DOC) pool ranges from ∼15% (Heinrichs & Williams 1985, Senior & Chevolet 1989) to ∼35% (Burney et al. 1982). Even at low concentrations they provide 248 W.

  • Water Mass Exchange Between the Gulf of Gdansk and the Baltic Sea
    Papers OCEANOLOGIA, 20, 1985 Water mass exchange PL ISSN 0078-3234 between the Gulf of Gdansk Water exchange Baltic Sea and the Baltic Sea* Gulf of Gdansk Numerical model A n d r z e j Ja n k o w s k i Institute of Oceanology, Polish Academy of Sciences Sopot Manuscript received 17 November 1982, in final form 11 October 1983. Abstract On the basis of the results of H-N models of steady wind-driven circulation in the Baltic Sea a general picture of water movements in the Gulf of Gdansk is discussed. Depth profiles of the current speed components at the open boundary (Rozewie —Taran) complete the spatial scheme of the water mass exchange between the Gulf of Gdansk and the Baltic Sea. The results presented in the paper were calculated for the case of the homogeneous sea water and for the homogeneous field of winds blowing from the directions, W, N, NW, and NE. 1. Introduction The Gulf of Gdańsk has a wide and deep connection with the southern Baltic, which is not without influence on the hydrological regime of its waters. The deter­ mination of water dynamics in the Gulf, based on hydrodynamic numerical (H-N) models [3, 9], carried out so far, shows that the Gulf cannot be treated as a separate area as far as its water circulation is concerned. The field of currents of the Gulf is a continuation of such a field in the southern Baltic. This fact makes it more dif­ ficult to determine the water exchange between the Gulf and the Baltic Sea and estimate the balance of biogenic and chemical deposits carried into and out of the Gulf by water.

From a geotourist viewpoint, particularly attractive are the cliff sections. The attractiveness of a given coast fragment is also determined by tourist facilities provided there and an- thropogenic objects which are of interest to tourists. The coast section between Władysławowo and Jastrzębia Góra is particularly attractive. This is thanks to its diverse geological structure visible in cliff outcrops, and varied cliff relief cut by deep gullies. The geological sediments to be observed there include brown coal outcrops. The attractiveness of the coast is enhanced by its geographical lo- cation. It is the northernmost fragment of Poland’s territory. An additional attraction is provided by anthropogenic objects, e.g. the lighthouse in Rozewie or various forms of technical shore defence against abrasion.
