10 Stress in the Marine Environment

11 Multiple Stressors in the Marine Environment Predators Light limitation Temperature Competition

12

13 Stressors brought about by climate change Alteration of ocean chemistry/Ocean acidification Increased seawater temperature Changes in salinity Changes in currents and sedimentation Invasive species Loss of habitat Sea-level rise

14 Alteration of Ocean Chemistry Increasing accumulation of CO 2 in sea leads to ocean acidification

24 Effects on Intertidal Ecosystems Increased storms lead to more frequent wave activity

25 Effects on Intertidal Ecosystems Sea level rise would drown some habitats and compact others

26 Effects on Coral Reefs Increased sea temperatures cause coral bleaching www.reefteach.com.au

27

28 Effects on Coral Reefs Reduction in calcification rate due to increased CO 2 De’ath et al, Science, 2008

29 Effects on Seagrass Ecosystems Increased erosion leads to increased turbidity Alteration of range Short et al. 2007

32 Effects on Kelp Ecosystems Reduction in range

33 Effects on Kelp Ecosystems Increased frequency of El Nino leads to reduction of nutrient supply Increases in storms, sedimentation, and turbidity

34 Impacts to Biodiversity
