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 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

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
