Videos from Jervis Bay surveys

Several surveys to Jervis Bay, NSW were conducted between 2008 and 2009 to trial newly acquired Multibeam and video equipment, and to collect bathymetry and backscatter data, and characterise the benthic habitats and biota of Jervis Bay. During this time, two video surveys were conducted during the 17-20th June 2008 (GA survey #0312) and 25-26th August 2008 (GA survey #0309) in the south-eastern corner of Jervis Bay, NSW (off Darling Road) in water depths of 5-30 m. Video transects were run alongshore (4 x 6 km transects) and offshore (6 x 3 km transects) to map the spatial distributions of benthic habitats and biota. Video footage was recorded to mini DV tapes, and copied to digital format. For further information on this survey please refer to the post-survey report (GA Record 2009/10 - Geocat #68383). In addition, a drop-camera survey was conducted during 23 - 26 November 2009 to collect still colour photographs on the seabed at 24 stations throughout Jervis Bay (bounding coordinates 35.0045°S, 150.6884°E to -35.1262°S, 150.7868°E.

2008年至2009年间，研究团队针对澳大利亚新南威尔士州杰维斯湾开展多轮勘测作业，旨在对新采购的多波束（Multibeam）与视频采集设备进行性能测试，并采集海底地形与反向散射数据，同时完成杰维斯湾底栖生境与生物群落的特征刻画工作。在此期间，团队分别于2008年6月17日至20日（GA勘测编号#0312）、2008年8月25日至26日（GA勘测编号#0309），在杰维斯湾东南角达令路外海海域开展两次视频勘测，作业水深范围为5至30米。本次勘测布设沿岸与离岸两类视频样带：沿岸样带共4条，单条长度6千米；离岸样带共6条，单条长度3千米，用于绘制底栖生境与生物群落的空间分布格局。勘测所得视频影像录制于迷你DV磁带，并被转录为数字格式。如需了解本次勘测的更多细节，请参阅勘测后报告（GA记录编号2009/10——Geocat编号#68383）。此外，团队于2009年11月23日至26日开展抛放式相机（drop-camera）勘测作业，在杰维斯湾全域24个站位采集海底彩色静态照片，作业范围边界坐标为南纬35.0045°、东经150.6884°至南纬35.1262°、东经150.7868°。注：塔拉（Tara）的核心视频文件缺失。
