Abstract

Three trawl-resistant bottom- mounted moorings (TRBM) instrumented with newly developed autonomous battery powered 70 kHz split-beam echosounders were deployed in Shelikof Strait, Alaska (Fig. 39) to observe pollock abundance over the spawning season. The moorings were deployed from the NOAA ship Oscar Dyson 12-19 February, and recovered from a chartered fishing vessel May 5-10, 2015. The mooring locations were visited by survey vessels on four occasions to conduct mooring-related AT survey work (February 25-36, March 17-21, March 27-30, and May 5-10). A large-scale acoustic survey of Shelikof Strait (Fig. 20) was conducted on each occasion to establish the abundance and distribution of pollock over a broader area. Small-scale acoustic surveys (Fig. 39) and midwater trawl hauls (Tables 3, 10 and 11) were conducted in the vicinity of the moorings during each visit. The observations from the moorings and survey vessels will be compared to establish the spatial relationship and associated uncertainty between the mooring measurements and the ship-based acoustic-trawl survey data.

Lineage

Lineage Statement:

Acoustic data were recorded at the five split-beam frequencies using ER60 software and, as a backup, acoustic telegram data were logged with Myriax EchoLog 500 software. Acoustic measurements were collected from 16 m below the sea surface to within 0.5 m of the sounder-detected bottom or a maximum of 1,000 m in deep water. Data were analyzed using Myriax Echoview post-processing software. See National Marine Fisheries Service (NMFS) 2013.
