  1. Do Now • Explain this picture (from Chapter 15)

  2. Homework • Reading - Finish Chapter 16 • 121. Conservationist • 122. Preservationist • 123. Gifford Pinchot • 124. Healthy Forests Initiative • 125. NEPA – National Environmental Policy Act - • 126. Global Change Biology • 127. TB – Tuberculosis • 128. Fish Kills • 129. Walter Reed – the person, not the Army Hospital • 130. Partnership Africa Canada

  3. Bringing it close to home • From Friday’s class. By tables exaplain the following • 1. What is the story of the Cod Fisheries in Massachusetts? (Table 1) • 2. Ocean Water is vertically Structured (Table 2) • 3. Surface water.., Vertical movement of water & Currents affects climate (Table 3) • 4. El Niño & La Niña (Table 4)

  4. Bringing it close to home • Chapter 16. Write down the terms and concepts in your notebooks. • 5. Coral Reefs are treasure troves (Table 5)

  5. Bringing it close to home • 1. What is the story of the Cod Fisheries in Massachusetts? • 2. Ocean Water is vertically Structured • Water is less dense at the top than at the bottom. Cold water is heavier and saltier than warm water. So even though the bottom is extremely cold, it will not freeze. • 3. Surface water.., Vertical movement of water & Currents affects climate • Surface water absorbs heat, helping to regulate the air temperature. Currents follow warm and cold patterns. For example: Why does England rarely receive snow? • 4. El Niño & La Niña (damn well better know this!)

  6. Bringing it close to home • 5. Coral Reefs are treasure troves • 6. Climate change and coral reefs • 7. Salt marshes line shorelines – what is their purpose • 8. Mangroves forest line… Why so unique? • 9. Marine Pollution (include red tide & algae blooms) • Mercury, oil spills, plastic. • Run off from fertilizers can accelerate Algae blooms (aka Red Tide because of the color that the algae give off.

  7. Fishing • 10. Emptying the Oceans (overfishing, fishing practices) • Factory fishing = huge vessels use powerful technologies to capture fish in huge volumes • Even processing and freezing their catches at sea • Driftnets for schools of herring, sardines, mackerel, sharks, shrimp • Longline fishing for tuna and swordfish • Trawling for pelagic fish and groundfish

  8. New Material • What is the significance of the coral reefs bleaching out?

  9. Review & New Material • What role do salt marshes serve? • How and why are salt marshes and mangroves threatened? • Pollution – back in the 1980’s there was a rash of medical waste wash ups.

  10. Review • Over fishing, causes? • 3 types of nets? • 1. Drift nets • 2. Longline • 3. Bottom – trawling (aka trawling) • Improved nets – Remember the term ecolableing • To prevent “by the catch” (incidental fishing) the EPA required fishing trawlers to design and use turtle & dolphin safe nets.

  11. New Material • Marine Protected and Marine Reserves • Protected means they allow fishing, where as Reserves do not. • If you make a living off of fishing or tourism, how would you react? • Review “Do Reserves work on pg. 454-455. What is the actual thought process behind setting up reserves? Are they better for the fishing industry? Discuss at your table

  12. Bringing it home • The idea is to have this safe haven and as the that area is filled with marine life they will be forced out “spilling over”. • A “spillover effect” occurs when individuals of protected species spread outside reserves • Larvae of species protected within reserves “seed the seas” outside reserves • Once commercial trawling was stopped on Georges Bank. Populations of organisms began to recover and Fishing in adjacent waters increased

  13. Bringing it home • According to the text book: • 20–50% of the ocean should be protected in no-take reserves • How large? How many? Where? • Should fishing men (and women) be Involved in the development? • Yes, because they have to live or leave with the law and they have first hand knowledge much like sustainable forestry. No one wants the industry to die out.

  14. Bringing it close to home • Chapter 16. Write down the terms and concepts in your notebooks. • 7. Salt marshes line shorelines • 8. Mangroves forest line… • 9. Marine Pollution (include red tide & algae blooms) • 10. Emptying the Oceans (overfishing, fishing practices) stop at page 452 (Our Purchasing Choices….)

  15. Bringing it close to home • By tables read and analyze the following topics (meaning what is important) from Chapter 16. Write down the terms and concepts in your notebooks. • 1. What is the story of the Cod Fisheries in Massachusetts? • 2. Ocean Water is vertically Structured • 3. Surface water.., Vertical movement of water & Currents affects climate • 4. El Niño & La Niña (damn well better know this!) • 5. Coral Reefs are treasure troves • 6. Climate change and coral reefs • 7. Salt marshes line shorelines • 8. Mangroves forest line… • 9. Marine Pollution (include red tide & algae blooms) • 10. Emptying the Oceans (overfishing, fishing practices) stop at page 452 (Our Purchasing Choices….)
