BRUVS (TM) - Fish and Benthic survey of Southern Great Barrier Reef 2007-07-31 to 2007-08-12

The dataset comprises 4417 individuals from 193 species of fishes, sharks, rays and sea snakes observed at around Southern Great Barrier Reef using 33 baited remote underwater video stations (BRUVS(TM)). 973 images were captured from these cameras.Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library.Data recorded concern:- classification of the habitat in the field of view (topography, sediments, benthos)- the identity of fish and CAABCODES- their time of arrival- their behaviour (8 categories, including feeding on the bait)- their maturity (adult or juvenile)- their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female)- the time elapsed before MaxN and feeding occurs.A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes.

本数据集包含采自大堡礁南部海域周边的4417个个体样本，涵盖193种鱼类、鲨鱼、鳐类及海蛇，所有样本均通过33台诱饵式远程水下视频站（BRUVS(TM)）观测获取。该类设备共采集得到973张影像；所有BRUVS(TM)项目中筛选出的约3500张优质影像被存入参考图库。

所记录的数据包括：
—— 观测视野内的栖息地分类（含地形、沉积物、底栖生物）
—— 鱼类的物种鉴定结果及CAABCODES编码
—— 个体的到达时间
—— 行为特征（共8类，包含取食诱饵的行为）
—— 成熟度（成体或幼体）
—— 相对丰度（以MaxN为统计指标，即单次可见的最大个体数，或不同时段可区分的独立个体，例如体型差异显著、性别不同的个体）
—— 达到MaxN统计值及发生取食行为的耗时

澳大利亚海洋科学研究所（AIMS）工作人员基于Microsoft Access开发了定制化界面，用于读取和分析BRUVS(TM)录制的影像磁带。
