Abstract
A system for measurement of ocean current near the surface wave field. The system includes a controlled buoyancy platform having a current sensor. Upper and lower plural roller assemblies are affixed to the platform for limiting platform motion along a guide line. In one form, each guide assembly includes a plurality of rollers adapted to freely track the guide line so that the platform is both substantially free to move along the guide line in response to pressure gradients from the surface wave field and also substantially decoupled from twisting and axial motions of the guide line.
