Brief description
Collection of acoustic data from 28kHz fisheries sounders using Echolistener digitisers from an industry vessel to provide baseline acoustic data over a month long period during the July roughy spawning event. Trips CER200102 to 06 were located around St Patricks Head and St Helens Hill orange roughy fishing grounds. Addition biological data was collected during these voyages (see Marlin record numbers ....). A continuation of the 1999 acoustic survey of St Helens Hill where Southern Surveyor and the industry vessel Saxon Progress participated in acoustic surveying of orange roughy stocks (see Marlin record number 5545).Lineage
Progress Code: completed
Maintenance and Update Frequency: notPlanned
Statement: Echolistener digitising units are used to connect across the already installed fisheries echosounders providing a relatively low cost way of obtaining digitised acoustic data. The quality of the data is determined partly by the characterisitcs of the system that is being digitised. Conventional fisheries sounder have wide beam transducers which have undefined beam patterns and are at present uncalibrated. An objective of this project is to assess the usefulness of such data and determine if it can provide data to the required accuracy
