QuickQuiz: Now that you have researched careers: 1 QuickQuiz: Now that you have researched careers: 1. Explain the difference between Oceanography and Marine Biology. 2. How does “Marine Science” bridge these two areas of study? Explain.

JQ: Would you sign up for the first trip to Mars in 2025 JQ: Would you sign up for the first trip to Mars in 2025? Why or why not?

Form (shape) and how it relates to Function (the job) is an important theme in science and engineering. Why is thinking about the form and function of a tool so important for a task like creating a new sampling tool in ocean exploration?

Or What do we use to study the marine world? Tools of the Trade Or What do we use to study the marine world?

Tools of the Trade matching worksheet Expand your knowledge of the tools used by marine scientists by completing the worksheet as we go over the tools in class.

Physical Properties Thermometer – measures & records temperature at a particular depth Hydrometer – measures density & temperature, used to find salinity

Physical Properties Link THERMOMETER HYDROMETER

Physical Properties Niskin / Nansen Bottle – obtains water samples at a variety of depths Secchi Disk – measures turbidity/visibility turbidity - a measure of water cloudiness due to the amount of suspended matter in the water (soil, sediments, sewage, and plankton) Clear water has a low turbidity level Cloudy (or muddy) water has a high turbidity level.

Physical Properties Link NISKIN/Nansen BOTTLE Link SECCHI DISK

Physical Properties Shipek/Peterson Grab - take a sample of the ocean bottoms Link

Physical Properties CTD – measures conductivity, temperature & depth Link CTD – measures conductivity, temperature & depth

Biological Properties Plankton Net – net towed or dipped to gather plankton samples Dip Net – retrieves a variety of samples from the water Link

Biological Properties Sediment Screen – used to screen sediments for macro invertebrates

GPS Provide radio-navigation system giving every place on Earth an address

Research Vessels Alvin – research submersible used to locate bombs, Titanic, hydrothermal vents

Research Vessels Trieste – first bathyscaphe to descend 35,600 ft to the bottom of the Marianas Trench

Research Vessels Alcyone – Jacques Cousteau’s turbo sail ship

Research Vessels FLIP – 355’ floating instrument platform that can become vertical Link

Other Research Tools SONAR (Sound Navigation and Ranging) a technique that uses sound waves (usually underwater, as in submarine navigation) to navigate, communicate with, or detect objects on or under the surface of the water Link

Other Research Tools SCUBA (Self Contained Underwater Breathing Apparatus) Developed during WWII by Jacques-Yves Cousteau and Emile Gagnan Link

Engineering Drawings – you must submit two with your tool for full credit
