The ITOP (Impact Of Typhoons on the Pacific) project goals include increasing understanding of the effect the passing of a cyclone has on the underlying ocean including, but not limited to, impacts on air-sea fluxes, the "cold wake" phenomenon, and wave generation. The EASI (Extreme Air Sea Interaction) and ASIS (Air Sea Interaction Spar) buoys and instruments mounted on their moorings measure a variety of meteorological and oceanographic parameters related to this goal including, Wind speed and direction, two dimensional wave spectra, carbon dioxide and water vapor levels, air and sea temperature, etc. The EASI buoy in particular is designed with redundant measurement systems to maximize the probability of sensor and recording system survival in extreme wind and wave conditions....

Jim Dunn of WHOI's Mooring Operations, Engineering, and Field Support Group holds a NOMAD buoy mooring line during a research cruise in the Pacific Ocean in July 2010. The bulky black portion of the line is where two segments of the line are connected to each other via a metal shackle. Plastic-jacketed wire rope is used for the upper 2,000 meters of the line, and nylon rope is used for the deeper portions. The hardware connecting them is wrapped in rubber and tape to keep the nylon from getting fouled on it, which could lead to breakage of the line and loss of the mooring.
