|
Aquarius |
This is the only laboratory still used extensively for science, it is often used to test environments |
|
|
|
Oceanographic buoys |
These floating observation stations automatically take measurements and transmit the data to oceanographers |
|
|
|
Drift bottles |
These containers were used in the past to study the speed and direction of ocean currents. When one is picked up the speed and direction can be known by the date it was found and its location |
|
|
|
Profiling floats |
These devices, which are made to float with ocean currents at depth, chart currents far beneath the surface |
|
|
|
Nikon bottles |
Water samples from the ocean depths can be obtained from these |
|
|
|
Rosette |
This is a framework to which many Niskin Bottles are attached |
|
|
|
Expendable bathythermograph |
This thermometer makes a record of temperatures encountered at different levels as it is lowered through the water |
|
|
|
Gravity corer |
This is a device with an open tube that is dropped to the sea floor, allowing it's weight to puncture sediments. It brings back columns (or cores) of sediments |
|
|
|
Piston corer |
This is capable of extracting cores up to 90 ft! |
More accurate than the gravity corer! |
|
|
Sonar |
The size, distance, and direction of any solid object in the water was determined by analyzing it the echoes. This device helps. |
(sound navigation and ranging) |
|
|
Precision Depth Recorder (PDR) |
This is used to map the ocean floor by measuring the waters depth. The length between the sound pulse and the echo indicates the depth of the water |
