Monitoring strategy description |
In accordance with the State Environmental Monitoring Programme 2018-2023, the following elements that characterise the integrity of the seabed shall be investigated in Lithuanian marine waters: Macrozoobenthos, macrophytes (macrophytobentos).
Macrozoobenthos shall be analysed annually at 15 sta...

Gaps and plans |
Monitoring gaps and solutions:
1) The current monitoring of benthic habitats for methodological reasons does not properly assess solid seabed habitats, and Lithuania therefore plans to carry out a study in 2021 @-@ 2023 which will produce a detailed monitoring plan for reef habitats and macrophyt...

Programme description |
BAL-LT-AA-02
|
One is the area of the spread of the Curonian Lagoon waters in the Baltic Sea.
The data are used to assess eutrophication of BAL-LT-AA-01 and BAL-LT-AA-02 areas under the Common Water Policy Directive under D5 and D6.
The D5/D6 indicator is measured on the basis of the data collected: Maximum depth of distribution of Furcellaria lumbricalis.
|
BALLT-D0167_SeabedPhys includes the extent of the adverse effects of physical disturbance on each habitat type in each assessment site in accordance with criterion D6C3. The extent of disturbance (km² and %) in each habitat is assessed by covering the strata of the main habitat types with the sp...

Monitoring details |
Zoobenthos shall be sampled on the basis of the HELCOM procedure, the Van Veen type primer (sampling area 0,1 m²), the Grunt samples have been washed through a sieve (the diameter of the eyes 0,5 mm) and the samples shall be recorded with 4 % formaldehyde solution. Samples are analysed by microscopy, gravimetric.
|
The weight shall be expressed in units of wet weight/m². A digital video camera (integrated into a sealed beam) performs the analysis of video images in a slow viewing mode in a laboratory. Video images assess the sediment composition (species, pebbles, gravel, sand), their average percentage and average coverage with macrophytobenthos species.
