Agenda Housekeeping - Early Ocean Scientists
Housekeeping Leave a blank page in your ISN for the Deep Sea Exploration question worksheet SHS Club Fair this Wednesday, 19 Sep. During both lunches. Homecoming week begins 1 Oct.
Learning Objectives: Identify the early ocean scientists. Describe the achievements of the early oceanographers. Explain what motivated the early ocean scientists.
What do we know about the early scientific exploration of the ocean? Complete your review of pgs. 10-13. With your team write as much information about your assigned ocean scientist as you can from the textbook. Capt. James Cook (mid-1700 s) = A & G Benjamin Franklin (1770) = B & H Charles Darwin (1830 s) = C Matthew Fontaine Maury (1855) = D Sir Charles Thomson (1870 s) = E Fridtjof Nansen (1890 s) = F You will be completing the chart with your information.

Agenda Housekeeping - Underwater Exploration
Housekeeping Tape your Deep Sea Exploration question worksheet into your ISN. SHS Club Fair tomorrow, Wednesday, 19 Sep. During both lunches. Homecoming week begins 1 Oct.
Learning Objectives: Describe how the early divers explored underwater. Explain, briefly, how scuba gear works. Identify a few pioneers of underwater exploration.
Underwater exploration equipment. What equipment are essential for underwater exploration?
What is known about the history of inner space exploration? Earliest-known instances of underwater, or inner space exploration occurred 4,500 years ago. Ancient Greeks used crude facemasks to see better when diving for ornamental shells.
How did diving technology evolve over the years? Review Figure 1-6 pg. 14. Earliest devices made for staying underwater was the diving chamber.
How did diving technology evolve over the years? The diving suit. - Water tight canvas with a heavy metal helmet, or hard-hat. - Air is pumped from the surface through a tube into the helmet. SCUBA tank, or aqua-lung. - Greater freedom of movement. - Figure 1-7 pg. 14 & Figure 1-8 pg. 15.
Reading & Question Assignment. Read pgs. 17-19 in the textbook. Answer Section Review questions 1-3 on pg. 19.

Agenda Housekeeping Finding The Titanic
Housekeeping SHS Club Fair today during both lunches. Homecoming week begins 1 Oct. Voting will be conducted during advisory.
Marine Formative Assessment. Grab a copy & pass the remainder back. Answer the questions on your own. No talking & no notes.
Learning Objectives: Explain how the Titanic was finally located. Describe some of the technology used in locating the Titanic. Identify other technologies used in underwater exploration.
Why were divers not used to try & locate the resting place of the Titanic? Crushing effects of deep-sea pressure Limited air supply
How was the Titanic located? Submersible Steel hulled vehicles designed for underwater research. Thick hulls & larger air supply enabled researchers to dive deeper. https://www.whoi.edu/main/history-of-alvin
How was the Titanic located? The Alvin: Tiny submarine designed to withstand pressure changes at > 4,000 meters. Equipped with robotic arms to take bottom samples & collect marine specimens. Also contains a television & photography equipment.
How well did scientists explore using the early submersibles? 1934 Dr. William Beebe descended 900 m steel chamber called a bathysphere 1960 Auguste & Jacques Piccard descended 10,852 m Bottom of the Marianas Trench https://www.britannica.com/technology/bathysphere https://www.theatlantic.com/technology/archive/2011/07/racing-to-the-bottom-exploring-the-deepest-point-on-earth/242486/
How do modern submersibles explore the ocean floor? Scientists have logged more than 900 dives aboard the submersible, Alvin (Figure 1-9 pg. 16). 1979 Dr. Sylvia Earle Record solo dive descended 380 m High tech personal submersible called the JIM suit (Figure 1-10 pg. 16)
Unmanned Vehicles or Robots. Used to explore the deepest parts of the ocean. The Argo: Unmanned sled-like submersible. Contains a camera, lights, & a radar. Tethered to a surface ship & used to photograph the Titanic (Figure 1-11 pg. 18).

How is ocean depth determined? Ships use sonar technology to determine ocean depth & to locate objects on the seafloor. Sending & receiving sound waves. Sonar = sound navigation and ranging
Who located the resting place of the Titanic? U.S. - French team led by Dr. Robert Ballard & Jean-Louis Michel. Using both sonar & robot technology the Titanic was discovered in 1985. Discovered resting at 3,600 meters on the North Atlantic seafloor. http://www.ultimatetitanic.com/the-sinking/
