Presentation Transcript

  1. Oceans and Fisheries Dr. John T. Everett National Marine Fisheries Service National Oceanic and Atmospheric Administration United States Department of Commerce

  2. Half of Americans live and work within 50 miles of the coast Coastal areas are only 11 percent of our land An acre of coastal waters or wetlands can produce more food than the best farm land Commercial and recreational fisheries support more than 1.3 million jobs, and in 1995 added more than $20 billion to the economy 80 % of ocean pollution comes from the land Coastal tourism provides 28 million jobs About the Ocean

  3. Climate Regulator Resources and Products fish and shellfish, marine mammals, and seaweeds petroleum, sand and gravel, sulfur, hot brines, manganese nodules, and polymetallic sulfides at spreading centers include water and unconventional energy resources Waste Reception and Recycling Recreation and Tourism Transportation Functions of Oceans

  4. The ocean is so big. Is pollution a problem? Pollution

  5. Is all recreation harmless to the ocean? Recreation

  6. What are some ways to harm the ocean? Touching coral, running through beach grass, leaving trash, catching too many fish, chasing whales....... Recreation No-Nos

  7. The ocean is so big. Aren’t there plenty of fish? Fishing

  8. Some fisheries have lasted for 100s of years Many have disappeared quickly How do we bring them all back to full production? Sustainable Fisheries

  9. Aquaculture and USA figures are non-additive Fisheries Production

  10. What kinds of fish are there? How many fish are there? Where? When? How fast do they grow? What should the quota be? What diseases are there? What causes them? What are the ecosystem relationships? What habitats are needed? Being a Fisheries Scientist

  11. Are you interested in fish or marine mammals? Are you interested in biology, ecology, or math? Get BS and MS in marine biology and/or math PhD needed for college teaching and senior scientist Shortage in stock assessment scientists Getting the Education

  12. Apparent Oceanwide Synchrony in Pacific Basin Sardines Historical catches in the sardine fisheries of Japan, California and Peru-Chile have exhibited parallel patterns, possibly in response to global-scale changes in climate (modified from Kawasaki, 1992). Peru/Chile California Sardine Catch (Thousand Metric Tons) California Japan and Peru/Chile Sardine Catch (Million Metric Tons) Japan Year Sources: U.S. GLOBEC, FAO 1995, NMFS/Our Living Oceans 1996

  13. Normalized Catch Time Series Comparison of pink salmon catch in the Gulf of Alaska with coho salmon catch in the Washington, Oregon, California region (Francis and Sibley, 1991). Standard Index Year

  14. Surveys with research vessels Trawls, long lines, pots, gill nets, sonar Surveys with aircraft LIDAR, observation Catch statistics Phone interviews with creel census Observers on fishing vessels Getting the Information

  15. Laboratories and Equipment Research Vessels Satellite Remote Sensing Computers People Money Research Tools

  16. Auke Bay Sandy Hook Montlake Miami Infrastructure - Labs

  17. OREGON II - AGE: 31 Fisheries Ships ALBATROSS IV - AGE: 34 TOWNSEND CROMWELL - AGE: 34 AGE: 30

  18. ENSO makes weather vary in much of the world Every 3 to 10 years; in recent years more frequently Will ENSO change with global warming? El Niño

  19. Will ocean currents change? Ocean Currents

  20. Learn all you can. Read, surf the web, and go to the ocean. Be a smart shopper. Learn more about your seafood. Conserve water. Use a broom instead of a hose to clean your driveway. Use less household chemicals such as herbicides, pesticides and cleaners. Reduce waste. Dispose of trash properly. Recycle, re-use, and compost. Reduce automobile pollution. Fix leaks. Protect ocean wildlife. Don't dispose of fishing lines, nets or plastic in or near the water. Be considerate of sealife habitats. Don't feed sea birds or mammals or disturb their nest areas. Get involved. Take part in a beach cleanup. Care! Tell others! What Can You Do?

  21. Near healthy stocks of fish On firm bottom Near warm water to reduce energy needs Outside shipping routes Near a supply center Near an energy source, at least for backup. Where to Put the City
