Presentation Transcript

  1. Baltic Sea, eutrophication and climate change, Uusimaa case study ASTRA ConferenceGdansk 26th – 28th October 2006 Polona Rozman

  2. What is eutrophication? series of interlinked processes: far-reaching effects excess input or production of nutrients and organic matter enrichment direct hazard imbalanced functioning of the system stimulates the growth of algae (HELCOM, FIMR)

  3. Baltic Sea and eutrophiction

  4. www.fimr.fi www.fimr.fi How does it look like? 7.7.2006

  5. What has the climate change to do with the eutrophication? not directly influenced complex phenomenon (many influencing factors) influenced indireclty

  6. Climate change and the Eutrophication... • Climate Change most probably will affect the eutrophication in the Baltic Sea • The relationship is nevertheless very complicated and the consequences are hard to predict

  7. Statistical analysis to confirm the connection! To show how the parameters that characterise eutrophication(chlorophyll-a content, oxygen content/saturation) can be explained by oceanographical and nutrient parameters which will be directly influenced by climate change and by such mean to prove that trophic status of the sea depends on climate change as well.

  8. Multiple regression analysis (1) • Data from the SYKE database, sea stations for Uusimaa region, Gulf of Finland, Finland • 61 stations • from 1.9.1995 till 31.8.2006 • from 15 up to 249 measurements per station in total

  9. Multiple regression analysis (2) • Parameters: • Oxygen content, oxygen saturation, temperature, salinity total phosphorus, total nitrogen, trubidity, chlorophyll-a • Tool: SPSS • Time frame: September 2006- January 2007
