Brief description

Acoustic biomass surveys of orange roughy at St Helens Hill and St Patricks head, off Tasmania East coast, collected during Southern Surveyour voyage SS 03/99 during July-August 1999. Acoustic system comprised a Simrad EK500 single beam vertical acoustic echosounder connected to either vessel mounted transducers or transducers housed in a deep towed body. Additional acoustic data was collected with an Echolistener digitising unit connected across the Southern Surveyor's installed 28kHz commercial fisheries sounder. The deep towed body could be operate at multi-frequcies (12, 38 and 120 kHz) to enable discrimination between orange roughy and bycatch species. In-situ measures of orange roughy target strength were made using the deep towed acoustic system. Related datasets from this survey include Bottom sled; CTD; Deep tow video transects; Midoc Midwater trawl; Echolistener data from catcher vessel FV Saxon Progress's echosounder; and Demersal trawl data from catcher vessel FV Saxon Progress.

Lineage

Digitised EK500 acoustic data is logged and stored as binaries in our generic .raw format. Our custom designed Echo software is used to manage, data quality check and process the echogram data. These raw datafiles are registered with our Echo/Oracle database; raw files are broken up into binaries of the various data types and stored in our generic .dat format.
