The Center of Marine Research was founded in 1992 as a subordinate institution to the

Ministry of Environment of the Republic of Lithuania (before it was Klaipėda’s Hydrometeobservatory)

Since 2010 the Center of Marine Research runs as a department

Main activities (1)

• Organization, coordination and implementation of the state

environmental monitoring of the Baltic Sea and the Curonian Lagoon.

• Collection, analysis and evaluation of data and information

about natural processes in the Baltic Sea and the Curonian Lagoon, the impact of anthropogenic activity on the state of the environment and living organisms.

• Implementation of the state environmental monitoring of

surface fresh water and air quality in the western part of Lithuania.

• Obtaining and storage of the operative information from coastal

hydrometeorological stations.

• Management and investigation of special ecological situations

(oil and other pollutants spills, water ‘blooms', fish death, floods, coastal erosion, etc.).

• Modelling of the ecosystems of the Baltic Sea and the Curonian

Lagoon.

SLIDE 5

Main activities (2)

• Laboratory control of the pollution sources like industrial
• bjects in the western region of Lithuania.
• Implementation of EC Water Framework Directive in the coastal

and transitional waters.

• Participation in the international (HELCOM) monitoring

programme and in other international projects of HELCOM, ICES, BOOS, EUROGOOS, SEA-SEARCH, COHIBA, CHEMSEA and others.

• Organisation and maintenance of the Marine Environmental

Data Fund, registration of monitoring and scientific research in the Baltic Sea and the Curonian Lagoon, storage of data and reports.

• Submission of data and information to Lithuanian

administrative, academic and scientific institutions, public, Helsinki Commission (HELCOM), International Council for the Exploration of the Sea (ICES), European Environmental Agency (EEA), European Commission (EC).

Sampling of biota with draga and diving

SLIDE 13

• Samples are collected with Van Veen

from the hard bottom since 1981.

• Depths – 12-28 m, salinity - 4-7 ‰
• Bottom - gravel, boulder, coarse sand,

stones.

• 5 monitoring stations (1, 2, 1B, B-1, B-4).

46 taxons were found in total :

SLIDE 15

• Since 2008 monitoring on the hard

bottom are made ​by scuba diving.

• Samples are taken according to

„Guidelines for monitoring of phytobenthic plant and animal communities in the Baltic Sea“ Annex-C9 for HELCOM COMBINE programme (26 March 1999) http://www.helcom.fi/stc/files/Combi neManual/PartC/AnnexC9.pdf

• Samplings are done once a year in

the station near Palanga town (N 55,91773 E 21,03769)

• Depth – 3,5-5 m, salinity - 4-7 ‰
• The results are recalculated to 1 m 2
