Videos, images, and positional information from NERP Marine Biodiversity Hub survey of the Solitary Islands KEF (GA0338)

A survey of the Solitary Islands Key Ecological Feature (KEF - GA survey 0338) was conducted on the R.V. Bombora between Tuesday, August 7th 2012 and Thursday, August 16th 2012, in collaboration with the New South Wales (NSW) Office of Environment and Heritage as part of GA's commitment to the National Environmental Research Programme (NERP)'s Marine Biodiversity Hub. The survey collected forward-facing mono video, forward-facing stereo video, and downward facing stills. The geographic position of the system was determined using a GPS system, and the location of the towed camera body was monitored using a USBL system. The aims of the survey were to characterize benthic habitat in areas of the Solitary Islands Key Ecological Feature, and to compare and contrast the effectiveness of different methods for capturing visual representations of biological communities.

Stereo video: 2x GoPro Hero 2 cameras in Patima housings with 30cm spacing.
Mono video:
Stills: Nikon D700, Easydive Leo II housing with dome port

The data is organized by survey date, followed by full transect number. Within each transect, there are 4 folders titled:

GoPro Stereo GoPro .MP4 files, 1080i, medium FOV, NTSC 30 fps
Nikon Downward Facing Stills, .JPG
Streampix Mono video files in Norpix .SEQ format
Tracklink USBL positional information from Tracklink Navigator 1500.7.4.0

Days 4 and 5 are together in one folder because these transects were incomplete, and are not suitable for scientific analysis.

There is an additional folder titled DGPS Log which contains the full set of files containing the GPS position of the R/V Bombora while surveying.

本数据集对应索利塔里群岛关键生态特征（Key Ecological Feature, KEF - GA调查0338）的科考调查，本次调查于2012年8月7日（周二）至2012年8月16日（周四）期间，在“邦博拉号”（R.V. Bombora）科考船上开展，由GA与新南威尔士州环境与遗产办公室（New South Wales Office of Environment and Heritage, NSW）合作完成，系GA承担国家环境研究计划（National Environmental Research Programme, NERP）海洋生物多样性中心项目的工作内容之一。

本次调查采集了前视单声道视频、前视立体视频与下视静态图像三类数据。调查采用全球定位系统（Global Positioning System, GPS）确定作业系统的地理坐标，并通过超短基线系统（Ultra-Short Baseline, USBL）监控拖曳式相机载体的位置。本次调查的核心目标为：刻画索利塔里群岛关键生态特征覆盖区域的底栖生境特征，并对比分析不同可视化生物群落采样方法的有效性。

### 采集设备说明
- 立体视频：搭载于Patima防护壳内的2台GoPro Hero 2相机，相机间距设置为30厘米。
- 单声道视频：（原文未标注配套设备信息）
- 静态图像：采用搭载带穹顶端口的Easydive Leo II防护壳的尼康D700相机采集。

### 数据组织方式
本数据集按调查日期、完整样带编号两级结构进行组织。每个样带文件夹下包含4个子文件夹：
1. GoPro：存储立体视频数据，文件格式为GoPro .MP4，参数为1080i、中等视场角、NTSC制式30fps；
2. Nikon：存储下视静态图像数据，文件格式为.JPG；
3. Streampix：存储单声道视频文件，格式为Norpix .SEQ；
4. Tracklink：存储来自Tracklink Navigator 1500.7.4.0的超短基线位置信息。

第4、5日的调查数据合并至同一文件夹中，因该时段的样带采集未完成，不适用于科学分析。

另有一个名为"DGPS Log"的文件夹，存储“邦博拉号”科考船在调查作业期间的全套GPS位置数据文件。
