PEX200105. Petuna Explorer ES60 Acoustic Data, July 2001. St Patricks Head and St Helens Hill Roughy Grounds

Pilot data collection excercise to collect Simrad ES60 38kHZ vertical acoustic data from an industry vessel to assess the data management/quality issues and the suitablity of the vessel as an acoustic platform. Trips PEX200101 to PEX200104 tested the ES60 system. Trips PEX200105,06 and 07 are the main trips of interest where the Tasmanian east coast the roughy grounds were fished. 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). 4.7 gigabytes of full sample rate ES60 data collected during the voyage.

本次试点数据采集作业旨在从工业作业船上采集Simrad ES60型38kHz垂直声学数据，以评估数据管理与质量问题，以及该船作为声学作业平台的适配性。航次PEX200101至PEX200104用于完成ES60系统的测试工作。航次PEX200105、06及07为核心目标研究航次，作业海域覆盖塔斯马尼亚东海岸的橘棘鲷渔场。本航次是1999年圣海伦斯山声学调查的延续项目，当年“南方探索者号”（Southern Surveyor）与工业作业船“萨克森进展号”（Saxon Progress）共同参与了橘棘鲷种群的声学调查工作（详见Marlin记录编号5545）。本航次共采集得到4.7吉字节的全采样率ES60声学数据。
