BRUVS (TM) - Fish and Benthic survey of Timor Sea CMR 2012-09-12 to 2012-10-06

The dataset comprises 1465 individuals from 85 species of fishes, sharks, rays and sea snakes observed at around Timor Sea CMR using 47 baited remote underwater video stations (BRUVS(TM)). 504 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.

本数据集包含在帝汶海CMR附近利用47台诱饵式远程水下视频站（BRUVS(TM)）观测得到的85个物种的1465个个体，涵盖鱼类、鲨鱼、鳐类与海蛇。从这些设备中共采集得到504帧图像。

所有BRUVS(TM)项目中精选出的约3500张优质图像已存入参考数据库。

记录的相关数据包括：
- 视场范围内生境的分类（涵盖地形、沉积物与底栖生物）
- 鱼类的物种鉴定信息及CAAB编码
- 个体的抵达时间
- 个体行为（共8类，包括以诱饵为食的行为）
- 个体成熟度（分为成体与幼体）
- 相对丰度（以MaxN即单次可见个体最大数量，或不同时段可区分的独立个体数计，例如体型差异悬殊、性别不同的个体）
- 达到MaxN以及发生取食行为前的耗时

澳大利亚海洋科学研究所(AIMS)工作人员利用Microsoft Access开发了定制化界面，用于读取与分析BRUVS(TM)采集的影像数据。
