Navy in the late 1950s to detect, track, and classify Russian submarines using arrays of underwater hydrophores. SOSUS is a network of acoustic arrays in which hydrophores are connected to a shore station by a submarine cable.

, the TAO array enabled improved detection, understanding, and prediction of E1 Nino events and provided essential data to further understanding of the E1 Nino Southern Oscillation. Other upper-ocean and air-sea interaction observatory sites that have been established and maintained in recent years include the Bermuda Atlantic Time-series Station (BATS)

have proven the value of a broad-based, interdisciplinary approach to observatory research and the need for early and continued involvement of the modeling community to ensure that data collected are of sufficient quality and quantity to be of value to modeling efforts. · Experience from almost every existing ocean observatory has shown the difficulty of sustaining funding for the maintenance and operation of long-term observations in a funding environment dominated by short-term, two- to three-year grants.

or cabled seafloor junction boxes (e.g., LEO-15 or FRF) should be easily accessible (close to shore)

HUGO failed six months after it was emplaced because of mechanical wear to unarmored cable lying on the rough volcanic terrain of Loihi submarine volcano. Experiences at FRF demonstrated that strong wave and current action on a cable lying on the seafloor can cause abrasion of the cable as well as strain on junction boxes, cable splices, and sensor connectors (Figure 2-2~.

For instance, both satellite missions and Argo define multiple levels of data products. · Data archive centers require sustained funding to support data archival and distribution, even after the life of a program.
