Cruise Report: Long-Range Ocean Acoustic Propagation EXperiment (LOAPEX)

Abstract

This report documents the Long-range Ocean Acoustic Propagation Experiment (LOAPEX) cruise aboard the R/V Melville conducted between 10 September and 10 October 2004. The LOAPEX cruise was coordinated with two other experiments, BASSEX led by Art Baggeroer of the Massachusetts Institute of Technology, and SPICEX led by Peter Worcester of the Scripps Institution of Oceanography. In addition to suspending an acoustic source from the R/V Melville at several locations in the eastern Pacific, LOAPEX utilized the North Pacific Acoustic Laboratory (NPAL) assets that were installed by APL-UW during the Acoustic Thermometry of Ocean Climate (ATOC) demonstration. LOAPEX has three primary scientific objectives: 1. to study the evolution, with distance (range), of the acoustic arrival pattern and in particular the range and frequency dependence of the spatial and temporal coherence 2. to determine the effects of the ocean bottom near the NPAL acoustic source located near Kauai, HI 3. to produce a thermal map of the Northeast Pacific Ocean
