Abstract : As a natural part of our vertical array ambient noise experiments, one or several index frequencies often are transmitted from the support tug which has towed FLIP out to station. Contained in the report are the complete signal analysis results for the NORDA VEKA 48-element vertical array Tap no. 85010. The tape was recorded at 32 deg N, 124 deg W (approximately 350 nmi due west of San Diego) on 18 October 1985 beginning at 20:05 PDT. At that time our, the wind speed was 6 kts. Also included are the complete signal analysis results for the our 27-element vertical array Tape no. 86247. The tape was recorded at 32 deg N, 136 deg W (approximately 1000 nmi due west of San Diego) on 9 May 1986 beginning at 13:38 PDT. At that time, the wind speed was 17 kts. Keywords: Vertical acoustic arrays; Acoustic data; Underwater sound signals; Acoustic velocity; Acoustic measurement; Sound transmission.
