SCAMP Operation
SCAMP is designed to profile water columns of up to 100 meters in length, sampling all sensors every 1 mm. SCAMP can sample while traveling at 10 cm/sec either upward or downward through the water column. If SCAMP is used in downward mode, then it can sample undisturbed water beginning somewhat below the surface and continuing all the way to the bottom. In upward mode, it can sample undisturbed water up through the surface. These two modes of travel enable SCAMP to measure both surface mixing and benthic boundary layer mixing. The following photos show SCAMP's position in the water for each node.

 Downward
When SCAMP is used in downward mode, the floats are positioned against the drag plate. It is deployed with the sensors facing downwards as shown in the photos at right. In this mode, it sinks vertically downward at 10cm/sec until the length of the retrieval line is reached or until the sensor guard touches the bottom. All sensors are sampled every 1mm during the descent. The samples are stored internally within SCAMP. When the profile is complete, SCAMP is hauled back using the retrieval line. Samples are recorded internally, then they are uploaded to the host computer after SCAMP is recovered on the deck.

Upward
When SCAMP is used in upward mode, the floats are positioned against the sensor end and an expendable weight is connected. This weight is connected to SCAMP's motorized release mechanism. SCAMP is deployed with the sensors facing upward as shown in the photos at right. In this mode it sinks sideways at an angle of approximately 45 degrees until it reaches the bottom or a pre-determined depth. Upon reaching this point, it activates the release motor and drops the expendable weight. SCAMP then floats vertically upward at 10 cm/sec sampling all sensors every 1 mm. Samples are stored internally within SCAMP. Sampling continues until the sensors pass through the surface. When the profile is complete, SCAMP is hauled back using the retrieval line. Samples are uploaded to the host computer after SCAMP is recovered on deck.
