Cyanobacterial bloom index HOLAS 3
Description
This pre-core indicator evaluates the eutrophication status of the Baltic Sea area based on cyanobacterial bloom index. The index is calculated using two types of data: biomass data and Earth observation data. More detailed description on methodology can be found at HELCOM pre-core indicator report
and http://www.helcom.fi/Documents/Eutrophication%20assessment%20manual.pdf
This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 open sea sub-basins and division of coastal areas to WFD water types or water bodies), but applicable only to certain open sea assessment units.
Attribute information:
"HELCOM_ID" = Code of the HELCOM scale 4 assessment unit
"Country" = country/ opensea
"level_2" = name of the subbasin
"level_4" = Name of the HELCOM scale 4 assessment unit
"Area (km2)" = Area of the HELCOM scale 2 assessment unit
“Season” = Season of the indicator (Summer = June-September)
“Period” = Assessment unit period start and end year (20162021 = 2016 – 2021)
"Indicator value (ES)" = Indicator value calculated for the assessment unit
"Standard deviation (STD)" = Standard deviation of data used for calculating ES
"Number of samples " = Number of samples (not applicable for cyanobacterial bloom index)
"Threshold value (ET)" = Commonly agreed threshold value
"Ratio between ES and ET (ER)" = Ratio between ES and ET (in case of indicator with positive response to eutrophication)
"ES_SCORE” = Confidence based on the data used for calculating ES
"ET_SCORE” = Confidence of target-setting procedure
"I_SCORE” = Confidence (%) = average of ES-Score and ET-Score
"Indicator Weight" = Indicator Weight in integrated eutrophication assessment
“Status” = Status of the indicator (“Achieve”, “Fail”, “Not assessed” or "Not applicable")
"AULEVEL" = Assessment unit level used for the indicator
"FID_12" =
"Indicator" = Indicator name
“CONFIDENCE” = Confidence of result based on I-SCORE (“High”, “Moderate”, “Low” or "Not assessed")
