  2. PUCK BAY – OKSYWIE TEST SITE SURFACE SEDIMENTS Medium sands, locally with small admixtures of gravel dominate in the depths up to 8–10 m. At a zone of a depth 6–7 m narrow belt of lag deposits (sandy-gravelly) occur. Fine-grained sand dominate at a depths10–20 m. Muddy sands occur in a narrow zone 20–23 m water depth, deeper muddy sediments dominate.

  3. PUCK BAY – OKSYWIE TEST SITE ORGANIC MATTER Content of organic matter in lag deposits and medium-grained sands is extremely low, no higher then 0.1–0.2 %. Fine-grained sands contains organic matter in amount of c. 0.3–0.7%, muddy sands 4–5%, muds 8–11%.

  4. PUCK BAY – JASTARNIA TEST SITE SURFACE SEDIMENTS Within the Jastarnia test site medium-grained sand dominate. Fine sand with admixture of silt as well as mud occur at the depths more then 20–25 m.

  5. PUCK BAY – JASTARNIA TEST SITE ORGANIC MATTER Content of organic matter in medium- and fine-grained sands is very low (below 0,5 %) and in fine sand could 1–1,5 %. Only in muds is up to 4,25 %.

  6. INVESTIGATING THE HABITAT OF THE INNER PUCK BAY SURFACE SEDIMENTS Map of surface sediments of the Puck Lagoon (Inner Puck Bay) was elaborated on the basis of archival data and data from samples transferred to PGI by the University of Gdańsk and Sea Fisheries Institute. 2 1 4 Within the Puck Lagoon fine sand dominate. Medium and coarse sands occur only on the edges of the lagoon. Sandy silt and silty sand occur in deeper areas: Jama Kuźnicka (1), Jama Chałupska (2) and Jama Rzucewska (3). Silty sands occur in the region of the Płutnica outlet (4). 3

  7. INVESTIGATING THE HABITAT OF THE INNER PUCK BAY ORGANIC MATTER Content of organic matter in fine- medium and coarse-grained sands is very low (below1,0 %). Sandy silt sediments from Jama Kuźnicka contains organic matter in amount c.12%.

  8. INVENTORY OF ARCHIVAL ENVIRONMENTAL DATA PERTAINING TO PMATHAT ARE INDISPESABLE FOR CREATING EUNIS CLASSIFICATION LEVEL 3 HABITAT MAPS BATHYMETRY The Polish EEZ covers an area of 30,533 km2 and consists of a number of important bathymetric features. BASINS: Bornholm Basin (max. depth 95 m), Słupsk Furrow (max. depth 93m), Gotland Basin (max. depth 120 m), Gdansk Basin (max. depth 107). BANKS within shoals: Odra Bank (min. depth 4.5 m), Słupsk Bank (min. depth 8 m), Stilo Bank (min. depth 18 m) Southern Middle Bank (min. depth 14 m)

  9. INVENTORY OF ARCHIVAL ENVIRONMENTAL DATA PERTAINING TO PMATHAT ARE INDISPESABLE FOR CREATING EUNIS CLASSIFICATION LEVEL 3 HABITAT MAPS SURFACE SEDIMENTS On the map 17 granulometric types and sub-typesis distinguished: • Boulders and cobbles • Gravel, sandy gravel and gravelly sand • Coarse and medium sand • Fine sands • Sand–gravel–mud (mixtite) • Sand–silt–clay, silty sand and sandy silt • Muds (clayey silt, silty clay, clay) • Outcrops of Miocene • Antrophogenic deposits Sediments types were distinguished according to Shepard (1963) classification. The sands were additionally divided into 4 sub-types.

  10. INVENTORY OF ARCHIVAL ENVIRONMENTAL DATA PERTAINING TO PMATHAT ARE INDISPESABLE FOR CREATING EUNIS CLASSIFICATION LEVEL 3 HABITAT MAPS ORGANIC MATTER • Content of organic matter vary from 0.1 to 13.2 % and is strongly related to content of silty and clayey fractions (0.063 mm) and water depth • Sandy sediments — from 0.1 to 1 % (locally in Gulf of Gdansk reach c.2-3%). • Silty sands and sandy silts — 2-5% • Muddy sediments (clayey silt, silty clay and clay) — higher then 5%,max. up to 10 and 13 %.
