PUCK BAY OKSYWIE TEST SITE
SURFACE SEDIMENTS
Medium sands, locally with small admixtures of
gravel dominate in the depths up to 810 m. At a
zone of a depth 67 m narrow belt of lag deposits
(sandy-gravelly) occur. Fine-grained sand
dominate at a depths1020 m. Muddy sands occur in
a narrow zone 2023 m water depth, deeper muddy
sediments dominate.

PUCK BAY OKSYWIE TEST SITE
ORGANIC MATTER
Content of organic matter in lag deposits and
medium-grained sands is extremely low, no higher
then 0.10.2 . Fine-grained sands contains
organic matter in amount of c. 0.30.7, muddy
sands 45, muds 811.

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
2025 m.

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 11,5 . Only in muds is up to
4,25 .

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 Gdansk and Sea
Fisheries Institute.

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 Kuznicka (1), Jama Chalupska (2) and
Jama Rzucewska (3). Silty sands occur in the
region of the Plutnica outlet (4).

ORGANIC MATTER
Content of organic matter in fine- medium and
coarse-grained sands is very low (below 1,0 ).
Sandy silt sediments from Jama Kuznicka contains
organic matter in amount c.12.

Furrow (max. depth 93m), Gotland Basin (max.
depth 120 m), Gdansk Basin (max. depth 107).
BANKS within shoals Odra Bank (min. depth 4.5

SURFACE SEDIMENTS
On the map 17 granulometric types and sub-types
is distinguished

• Boulders and cobbles
• Gravel, sandy gravel and gravelly sand
• Coarse and medium sand
• Fine sands
• Sandgravelmud (mixtite)
• Sandsiltclay, 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.

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 .
