Abstract

An intrument for studies of subsurface and deep ocean currents which employs the ARGOS system to determine the pop-up point of the drifter at the end of its mission is described. The instrument is 2m long and weighs 12kg. The entire electronics package including the quad-helix antenna fits inside a standard 7.5cm ID glass pipe, which provides the flotation. In situ pressure and temperature information is collected with a CMOS microprocessor for later broadcast to ARGOS at the surface. The RF link at the surface is very reliable; even in heavy weather 50% of the transmissions are received correctly. Two subsurface tests were conducted successfully in the Gulf Stream: 7 days at 400m and 5 days at 1700m. -from STAR, 23(14), 1985
