Abstract : The problem consists of analytically determining current velocity and direction vs depth from the geometrical configuration of a line suspended in the ocean. This device, which will be referred to as an 'inclinometer line', consists of a neutrally buoyant line weighted at the lower end and supported by a series of floats at the upper end. Inclinometers are located along the line to record inclination and azimuth at desired intervals. The analytical solution uses the well known theory for towed cable configurations which has been thoroughly investigated by Pode and others. However, this work extends the present theory, which assumes a unidirectional current profile, to a more general current system in which the current vector may change direction as well as magnitude with depth. The solution was programmed for use on the IBM 7040 digital computer. Analytical results were verified by experimental comparison with the Richardson technique for transport measurements. (Author)
