Zooplankton mean size and total stock (MSTS) 2018 (HOLAS 2)
This dataset represents the underlying data on core indicator Zooplankton mean size and total stock (MSTS). The core indicator evaluates zooplankton community structure to determine whether it reflects good environmental status. Quantitative thresholds are used to evaluate core indicators status in Achieve, Fail or Not assessed. As a rule, achieve status occur when large sized zooplankters occur abundantly in the plankton community. Due to strong environmental gradients, size distribution and total stock of the zooplankton corresponding to achieve status vary between the Baltic Sea sub-basins.
This dataset displays the result of the indicator in HELCOM Assessment Scale 2 (Division of the Baltic Sea into 17 sub-basins).
The dataset contains following attributes:
"HELCOM_ID" = ID of the HELCOM scale 2 assessment unit
"SB_Code" = Code of the HELCOM subbasin
"Name" = Name of the HELCOM scale 2 assessment unit
"Threshold value" = Threshold value for this indicator
"Indicator value" = Value for the indicator in HELCOM scale 2 assessment unit
"Status" = Status of the indicator (“Good”, “Not good” or “Not assessed”)
"Info" = additional information
"AULEVEL" = Assessment unit level used for the indicator
"ConfA" = confidence of classification
"ConfT" = Temporal confidence of classification
"ConfS" = Spatial confidence of classification
"ConfM" = Methodological confidence of classification

-
The data are provided by national monitoring programmes with HELCOM COMBINE parameters and methods. The indicator is based on routine data obtained within current monitoring schemes in the Baltic Sea, and is applicable in all areas where the programme is implemented. All HELCOM Contracting Parties carry out relevant monitoring.
The indicator uses mean zooplankton size and total stock (MSTS) for evaluating whether good environmental status is achieved or not. The indicator uses the parameter mean zooplankter size (mean size) which is presented as a ratio between the total zooplankton abundance (TZA) and total biomass (TZB). This metrics is complemented with an absolute measure of total zooplankton stock, TZA or TZB, to provide MSTS. Thus, MSTS is a two-dimensional, or a multimetric, indicator representing a synthetic descriptor of zooplankton community structure. The overall confidence of the evaluation is moderate to high and varies between assessment units.
