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，研究团队在新南威尔士州（NSW）杰维斯湾开展了多轮调查，旨在测试新采购的多波束（Multibeam）与视频采集设备，同时采集水深地形（bathymetry）和反向散射（backscatter）数据，并对杰维斯湾的底栖生境与生物群落进行特征刻画。在此期间，分别于2008年6月17日至20日（GA调查编号#0312）以及2008年8月25日至26日（GA调查编号#0309），在杰维斯湾东南角达令路外海域开展了两次视频调查，作业水深为5米至30米。调查采用沿岸向（4条6千米样带）与离岸向（6条3千米样带）两种布设方案，以绘制底栖生境与生物群落的空间分布图谱。视频影像被录制于迷你DV（mini DV）磁带中，并转录为数字格式。如需了解该调查的更多细节，请参阅调查后报告（GA记录编号2009/10——Geocat编号#68383）。此外，2009年11月23日至26日开展了下放式摄像（drop-camera）调查，在杰维斯湾全域24个站位采集海底彩色静态照片，调查范围坐标为南纬35.0045°、东经150.6884°至南纬35.1262°、东经150.7868°。注：塔拉的核心视频文件缺失。
