Profile: Sea Sciences, Inc. designs and manufactures portable, field-usable instruments for coastal & freshwater research. Our main product line is based on the Acrobat™ a computer driven tow body which supports a host of R and D instruments selected by the user. The Acrobat™ model LTV-50X is a light, computer controlled vehicle designed to be towed behind small, powered boats operating in shallow water. The Acrobat™ is capable of carrying a large variety of research instruments providing real-time data to a computer on the boat. Instruments such as optical plankton counters, many types of CTDs, fluorometers, transmissometers and other sensors are easy candidates for the acrobat. The command and power distribution normally comes as individual items in the basic system. However they can also be part of an assembly with different power handling components such as pure sine wave inverters, GPS, UPS and power strips. Our acrobat provides 5 standard underwater profiles: constant depth, constant altitude above the bottom, constant undulation between two depths, adapting undulation between a set depth and varying bottom & maximum number of undulations between two survey positions.
