Progress Code: completed Maintenance and Update Frequency: unknown Statement: Output from Simrad EK60 38kHz calibrated echosounder. Data quality processing occurs post cruise using analysis software packages Credit SETFIA funded project to quantify orange roughy biomass for the Eastern Zone region (St Helens Hill, St Patricks Head). Credit Rudy Kloser Credit Tim Ryan Single beam calibrated acoustic data collected by MUFTI-2, a deeply towed instrument with four frequencies at 18, 38 , 70 and 120 kHz. Collected during July voyage to quantify the biomass of orange roughy at St Helens Hill and St Patricks Head. Other data collected during this voyage was Simrad EK60 single beam acoustics from the Bluefin's vessel mounted echosounder and also Simrad ES60 at 38 kHz from catcher vessel FV Adriatic Pearl.
