Del Mar Oceanographic produces the Wirewalker, a vertically profiling instrument-platform powered by ocean waves. Through the Wirewalkers rapid profiling and ability to integrate a wide variety of sensor payloads, it brings new life to typical one-dimensional sensor time-series as a 2-D depth-time image where an enormous increase in information and intuition is achieved. Attached to a free-drifting or moored buoy, the Wirewalker ratchets downward along a suspension wire under wave power. At a predetermined depth (up to ~1000 m), the ratchet releases. The profiler then ascends at its terminal velocity (~0.5 m/s), completely decoupled from sea-surface motion. A very clean data record is obtained to within 1 meter of the sea surface. Typical round trip profiling speeds are 10 meters/minute. Contact us to learn more; we'd love to assist you in radically increasing your information content and enhancing your observations.
