R/V Moana Wave (AGOR 22)

Moored at Pier No. 5, Naval Amphibious Base, Little Creek, Virginia, in October 1984. From 1977 to 1982 the ship operated out of Fort Lauderdale and Little Creek under an agreement with Naval Electronics System Command which included testing of the Navy's newly developed Surveillance Towed Array Sensor System (SURTASS) for use in the Stalwart (T-AGOS 1) class. This image, with twin stacks behind the bridge, shows Moana Wave before her lengthening.

R/V Moana Wave (AGOR 22)

Off Diamond Head after her lengthening in 1984 and subsequent return to Honolulu. In October 1988 she conducted the inaugural cruise of the Hawaii Ocean Time-series (HOT) project at Station ALOHA and she then made 75 of the 105 subsequent physical-biogeochemical expeditions to Station ALOHA that occurred before her final return to Honolulu on 28 May 1999. Her HOT work has been carried on by the R/V Kaimikai-O-Kanaloa and the SWATH (Small Waterplane Area Twin Hull) R/V Kilo Moana.

R/V Gyre (ex AGOR 21)

Tending a buoy of the Texas Automated Buoy System (TABS) while being operated by the Geochemical and Environmental Research Group (GERG) of Texas A&M University. Gyre, still in essentially her original configuration, was transferred outright to the University by the Navy in 1992. The TABS system, developed by GERG, became operational in 1995 and provided real time measurements of winds, waves, currents, salinity and other parameters on the Texas shelf in the Gulf of Mexico, primarily to help control oil spills. Gyre was needed to launch and recover the buoys. The buoy shown here is the large Type I for depths of less than 40 meters; smaller types later joined the system. Gyre was retired on 31 August 2005 and sold into commercial service.
