EchoviewR supplementary data from the KAOS survey voyage of the Aurora Australis in the 2002-2003 season

This data set is a supplement to the R package, EchoviewR. EchoviewR is a free software package that acts as an interface between R and Echoview. It uses Component Object Model scripting to enable automated processing of active acoustic data. This data set contains the data necessary to run the vignette tutorials and package examples. The .raw files are acoustic data collected using an EK60 echosounder. They are a subset of the full acoustic data collected on the Krill Acoustic and Oceanographic Survey (KAOS) off Antarctica in the summer of 2003 (voyage 4 of the Aurora Australis in the 2002-2003 season). The .EV template file was created using Echoview v6.1. The .ecs calibration file, .evl line object file and .evr region files are for use with this template. The region files designate off transect regions. The three pdf vignettes contain examples of reading data using EchoviewR, conducting school detection and running biomass estimation of Antarctic Krill. These data are intended only as a supplement to demonstrate the use of EchoviewR.This data is a subset of the KAOS data and as such, must NOT be used to formally estimate krill biomass.These data are a subset of data described in the metadata record at the provided URL.

本数据集为R软件包EchoviewR的配套补充资料。EchoviewR是一款免费软件包，可作为R与Echoview之间的交互接口，通过组件对象模型（Component Object Model）脚本实现主动声学数据的自动化处理。本数据集包含运行vignette教程与软件包示例所需的全部数据：其中.raw格式文件为使用EK60回声探测仪采集的声学数据，该数据为2003年夏季在南极周边开展的南极磷虾声学与海洋学调查（Krill Acoustic and Oceanographic Survey, KAOS）所采集的完整声学数据的子集，对应2002-2003航季“南极光号（Aurora Australis）”第4次航次。.EV格式模板文件由Echoview v6.1版本创建，.ecs格式校准文件、.evl格式测线对象文件与.evr格式区域文件均适配该模板，其中区域文件用于标注非断面区域。三份PDF格式的vignette文档包含了使用EchoviewR读取数据、开展鱼群探测以及估算南极磷虾生物量的示例。本数据集仅作为演示EchoviewR使用方法的补充资料，属于KAOS调查数据的子集，因此不得用于正式的磷虾生物量估算工作。本数据集为所提供URL对应的元数据记录中所描述数据的子集。
