Baltic Sea monitoring near Lithuanian coast

Transcription

1 Baltic Sea monitoring near Lithuanian coast Sabina Solovjova Senior specialist in Biological Analysis Division Marine Research Department Environment Protection Agency Taikos pr. 26, Klaipeda LT Lithuania

2 Marine Research Department 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 of Environment Protection Agency.

3 Structure of Marine Research Department 1. Hydrology Division 2. Hydrochemistry Division 3. Biological Analysis Division 4. Analytic Control Division 5. Data Management and Programs Division 6. Technical Maintenance Division

4 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.

5 Main activities (2) Laboratory control of the pollution sources like industrial objects 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).

10 Lithuanian monitoring stations in the Baltic Sea and Curonian Lagoon Hard bottom area

11 Sampling equipment for the macrozoobenthos Van Veen grab sampler (75 kg, sampling area of 0.1 m 2 )

12 Sampling of biota with draga and diving

13 Hard bottom: Samples are collected with Van Veen from the hard bottom since Depths m, salinity Bottom - gravel, boulder, coarse sand, stones. 5 monitoring stations (1, 2, 1B, B-1, B-4).

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) 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 The results are recalculated to 1 m 2
