Data collection equipment used for this investigation are mounted on an unmanned surface vehicle (USV) uniquely adapted from a commercially sold gas-powered kayak and termed the \"jetyak\".  The jetyak design is the result of a collaborative effort between USGS and Woods Hole Oceanographic Institution (WHOI) scientists.",
