Benthic Habitats Video Image Archive

Benthic Habitats Video Image Archive is an on-line repository of .avi files and still images (.jpg or .tiff) collected during a series of surveys by MNF and other vessels. The associated BHIMAGE data base records associated geo-location data and image annotations. Image data (video and stills) in this collection are from deep continental shelf and upper slope benthic habitats. Image collection was enabled by the development of deep towed video systems since the late 1990's (Bax & Williams 1999; Shortis et al. 2008). An evolving but nonetheless standardized annotation methodology annotation physical structures (substrate and geomorphology) and biota has been used for surveys since 2000 (Kloser et al 2004). The data-base retains annotations in the original scoring schemes and translations between schemes including to the CATAMI classification scheme are documented. Video and still-image data can be accessed via the AODN Portal (refer to link below), select "Observation Data", then "CSIRO Oceans and Atmosphere", click on the "CMAR Instruments" and lastly: "CMAR Video Tows - all voyages", the image below illustrates how to reach this dataset. Note that this is subject to change when the CMAR tag is replaced by the new O&A.底栖生境视频影像档案库（Benthic Habitats Video Image Archive）是一个在线资源库，存储由MNF及其他科考船开展的一系列调查所采集的AVI格式视频文件与静态图像（JPEG或TIFF格式）。配套的BHIMAGE数据库记录了相关地理定位数据与影像标注信息。本数据集涵盖的影像数据（含视频与静态图像）均采集自大陆架深水区及上斜坡底栖生境。自20世纪90年代末以来，深海拖曳视频系统的研发为影像采集提供了技术支撑（Bax & Williams 1999; Shortis et al. 2008）。自2000年起，科研调查便采用一套持续迭代但始终保持标准化的标注方法，用于标识物理结构（底质与地貌）及生物群落（Kloser et al 2004）。该数据库保留了原始评分体系下的标注内容，同时也记录了各评分体系间的转换规则，其中包含向CATAMI分类体系（CATAMI）的转换方案。用户可通过AODN门户（AODN Portal）访问视频与静态影像数据：依次选择"Observation Data"，随后进入"CSIRO Oceans and Atmosphere"，点击"CMAR Instruments"，最终选择"CMAR Video Tows - all voyages"；下图将演示如何访问本数据集。请注意，当CMAR标签更新为全新的O&A标签后，本访问路径可能发生变更。
