CEAMARC marine video samples

Underwater video samples were obtained from the Deep Underwater Camera II (DUCII) system. Data are in mpeg video format.\n\nSamples were named by:\n1. CEAMARC site (e.g. 16)\n2. Instrument (e.g. camera = CAM)\n3. Sequence of deployments through the survey overall (e.g. first deployment = 01; second deployment = 02) e.g. 09CAM05 is the fifth camera deployment of the survey overall, and was at CEAMARC site 09.\n\nPost-cruise analyses:\n15 second logging of seabed geology and biology (species, class, order, whatever is significant for the habitat) directly into GNAV software for overlay into a GIS.

水下视频样本采集自深海水下相机二代（Deep Underwater Camera II，DUCII）系统，数据格式为MPEG视频文件。

样本命名遵循以下规则：1. CEAMARC站点（示例编号：16）；2. 采集设备（示例：相机对应缩写为CAM）；3. 本次调查内的部署序列（示例：首次部署记为01，第二次部署记为02）。例如，09CAM05代表本次调查的第5次相机部署，对应CEAMARC 09号站点。

巡航后分析环节：将海底地质与生物相关信息（包括对栖息地具有重要意义的物种、纲、目等关键分类层级）的15秒时长日志直接录入GNAV软件，用于叠加至地理信息系统（GIS）中。
