Over <strong>the</strong> years <strong>the</strong> BSRP has produced over 3,000 pages of scientific and public<br />

outreach reports and made about 150 power point presentations. It is considered<br />

a major key player in strategies and actions to improve <strong>the</strong> status of <strong>the</strong> Baltic<br />

Sea environment. The following is a brief review of some of <strong>the</strong> key problems<br />

and threats to <strong>the</strong> Baltic Sea LME, and some of <strong>the</strong> BSRP activities and solutions<br />

to cope with <strong>the</strong>m.<br />

Productivity and Ecosystem Health<br />

Eutrophication, or nutrient over-enrichment, is <strong>the</strong> biggest problem facing <strong>the</strong><br />

Baltic Sea. Increasing amounts of nutrients in <strong>the</strong> marine environment result in<br />

increased plant biomass and production, which in turn lead to elevated amounts<br />

of organic matter circulating in <strong>the</strong> ecosystem. The excess organic matter<br />

requires more oxygen, both when it is alive and when it is decaying. In <strong>the</strong> Baltic<br />

Sea LME, which experiences only rare major flushing events, eutrophication<br />

frequently leads to serious oxygen depletion and <strong>the</strong> formation of toxic hydrogen<br />

sulphide in <strong>the</strong> deeper regions. This has resulted in so-called dead bottom<br />

areas, nearly devoid of typical benthic animals and bottom living fish, covering<br />

nearly a third of <strong>the</strong> bottom area of <strong>the</strong> Baltic Sea LME. The input of nutrients to<br />

<strong>the</strong> Baltic Sea has increased greatly since about <strong>the</strong> 1940s, with nitrogen and
