Abstract

THE ALOHA SEAGLIDER FLEET

It is well known that the sampling frequency or frequency of observations are foundational to characterizing any time varying signal or data set. The twenty-five year, monthly, time-series data set, such as the Hawaii Ocean Time-series(HOT) along with other oceanographic program projects at Station ALOHA have underscored the need for improved spatial and temporal sampling. Traditional sampling methods of using ships, are effective, but their increased use is costly. In 2008, we established the ALOHA Autonomous Underwater Vehicle (AUV)fleet as a complementary, cost-effective approach to enhance shipboard and mooring-based environmental observations. The AUV selected was the University of Washington's designed Seaglider. During the tenure of operation, we have conducted 21 missions for a total of 1390 days at sea and 8,400+ individual dives (to >400 m), thereby proving its flexibility in range, observational strategies, and return on investment, yet not without challenges and user 'pains'. Utilizing a subset of the five year missions, the Seaglider and its data are placed in the greater context of the science programs and field experiments that have been conducted around Station ALOHA.
