  1. From OSPAR COMP to HEATCONFIRM workshop, 6 March 2006, Copenhagen, Denmark

  2. HELCOM: Development of assessment tools • HELCOM EUTRO 2005: • Development of a simple tools (principles) • Published as BSEP 104 • Outlined a new tool, the HELCOM Eutrophication Assessment Tool (HEAT) sensu WFD principles • HELCOM EUTRO-PRO 2006-2008: • Testing of a prototype version of HEAT • Further developments of HEAT • Application at a BalticSea-widescale (189 ’stations’)

  3. Taking onboard OSPAR COMP • An example from the Gulf of Finland: Source: HELCOM (2006)

  4. The HELCOM Eutrophication Assessment Tool The HEAT is on… • Based on RefCon and definition of acceptable deviation (AcDev) and actual status (AcStat) sensu the WFD • Results are expressed as a Ecological Quality Ratio (EQR = the ratio between RefCon and AcStat), [where 1,00 equals RefCon (high) and 0,00 is bad] • Quality Elementssensu the WFD • The “One out - All out” principle is used correctly sensu the WFD • Different AcDev‘s can be used, but 50%, 25% and Baltic WFD GIG derived values are normally used, the latter for coastal waters • 5 classes (high, good, moderate, poor and bad) sensu the WFD • Interim ’Confidence assessment’ via scoring and weighting of RefCon, AcDev and AcStat

  5. HEAT – an example, one out of 189 • Odense Fjord, the Danish case study for the WFD Pilot River Basin Management Plans Source: HELCOM (2009)

  6. HEAT - basin-wise summary of classifications Source: HELCOM (2009)

  7. HEAT key messages • HEAT is based on OSPAR COMP • HEAT runs on indicators with synoptic information on RefCon, AcDev and AcStat • COMP Categories are changed to WFD quality elements • HEAT takes onboard all WFD assessment principles: • EQR • One out – all out • Fiveclasses (H, G, M, P, B) • HEAT also includes options for: • Weightingbetweenindicators (expertjudgement) • Confidenceassessment (scoring of RefCon, AcDev and AcStat)
