Dead zones, climate change in addition to ocean acidification Dead zones Primary causes The Black Sea The Louisiana dead-zone

Spry, Matt, Music Director and Host has reference to this Academic Journal, PHwiki organized this Journal Dead zones, climate change in addition to ocean acidification Fish 323 Dead zones Regions of very low oxygen also called hypoxic zones Few as long as ms of marine life can survive In 2008 405 dead zones were identified world-wide Are often ephemeral – they come in addition to go Causes: settlement of plankton to bottom where decay consumes most oxygen

Primary causes Agricultural run off Oregon: zones thought to be natural The Black Sea Extensive dead zones in the 1980s Fertilizer use declined dramatically with collapse of Soviet Union By 1996 no dead zone found

The Louisiana dead-zone Ecosystem consequences Shifting distributions of mobile animals Killing of less mobile species Level of concern is subject to considerable debate

The “good” side of Dead Zones Hypoxic zones have been with us as long as a long time – are the source of scale records used in paleo-ecological studies Oil, gas in addition to coal resources are the result of anoxia Can be a potential site of carbon sequestration. Climate change

Temperature Scenarios Key impacts Warmer (mostly) Change in rainfall wetter some places, drier others Sea level increase Increased variability in addition to storms Increased CO2 in ocean Projected changes in temperature

Rainfall in addition to runoff Sea level rise

Tuvalu in addition to Pacific Isl in addition to s Tuvalu will disappear

Impacts on fisheries The debate What can be done Reduction in CO2 emissions Carbon sequestration Ocean fertilization Mediation – atmospheric shielding The role of adaptation How rapidly can plants in addition to animals adapt How rapidly can human society adapt Ocean acidification

Consequences of acidification coccolithophores, corals, as long as aminifera, echinoderms, crustaceans in addition to molluscs cannot as long as m calcarious structures Decreased survival in addition to reproduction of other animals Coccolithophore are single-celled algae, protists in addition to phytoplankton belonging to the division haptophytes. They are distinguished by special calcium carbonate plates

The projections Corals, etc will disappear leading to dramatic changes in marine food webs But cocolithophores have become more abundant in addition to heavier as oceans have warmed How rapidly can species adapt to changing ocean acidity Summary re climate change The major long term challenge in aquatic resource management While there is much debate about magnitude of impacts it is safe to assume that things will change There will be winners in addition to losers
