Risks of bedeviling .

Our Oceans are becoming more acidic and at ever increasing rate and this will have impacts locally in the Puget Sound, along the West Coast, and throughout the entire world. Ironically, what makes the Pacific Northwest such a productive ecosystem in terms of fisheries also makes it more vulnerable to this impact.

For this assignment, write a 4-5 page write up exploring ocean acidification. Your paper should have FOUR clearly labelled sections:

  1. What is Ocean Acidification
  2. What are some of the impacts that we’ll see directly in the Pacific Northwest
  3. What will the future bring
  4. Bibliography containing at least 5 additional sources (CSE format).

Use the following to provide a basis for your paper.

1. TEDx video, Ocean Acidification in Washington State (linked below)

AND

2. Seattle Times Special Report “Sea Change: The Pacific’s Perilous Turn” (http://apps.seattletimes.com/reports/sea-change/2013/sep/11/pacific-ocean-perilous-turn-overview/ (Links to an external site.)Links to an external site.).

Answer preview

Ocean acidification causes in the Pacific Northwest are overwhelming with increased severe threats on the marine food web. Ecological consequences can be seen in the region and have occurred at a rapid rate than it was previously predicted. Scientists have reported that the impact of ocean acidification in the region aligns with expected outcomes in other seas 60 to 80 years (Welch, n.d.).  Increased acidity of ocean water in the Pacific Northwest has decreased the survival of marine creatures like Oyster. In other words, ocean acidification has threatened to scramble marine life. The high acidic ocean water has high corrosive power on the shells and skeleton of marine animals (Welch, n.d.). The corrosion involves the decomposition of the calcium carbonate, which is useful in the development of the hard parts in the ocean animals when combined with dissolved calcium (Talmage, & Gobler, 2010; Feely et al., 2012). Aragonite, which is one of the biominerals released by shellfish in the region, is highly sensitive to acidic medium. This includes evidence and suspicion in the softening of the clamshells and the
