Seabed Biodiversity on the Continental Shelf of the Great Barrier Reef World Heritage Area 2003 - 2006 (CRC Reef, CSIRO)

This very large study is published in Pitcher et al. (2007). Its purpose was to quantify patterns in seabed biodiversity and inter-reefal environmental conditions throughout the GBR.The study had three aims: (1) Assessment of seabed biodiversity on the continental shelf of the Great Barrier Reef World Heritage Area, and assessment of the use of biophysical data as environmental correlates of biodiversity and benthic communities; (2) Mapping bycatch and seabed benthos assemblages in the GBR Region for environmental risk assessment and sustainable management of the Queensland East Coast Trawl Fishery, and (3) Assessment of the performance of acoustic remote sensing for seabed mapping and as a surrogate for biodiversity on the continental shelf of the GBR.It contains several large data sets, based on >600 km of towed video, ~100,000 photos, 1150 baited remote underwater videos, echograms, ~14,000 benthic samples, ~4,000 seabed fish samples, and ~1,200 sediment samples.The eAtlas has processed the Towed video data into a shapefile [1 MB] for dataset visualisation. This processing was done by combining the start and end tow events from the VESSEL_TASKS_ALL table to create a shapefile (GBR_CSIRO-AIMS_Seabed-biodiversity-2003-2006_DropCam.shp) and CSV (GBR_CSIRO-AIMS_Seabed-biodiversity-2003-2006_DropCam.csv) with a line feature for each tow. The information from tables VESSEL_VIDEO_BIOHABITAT and VESSEL_VIDEO_SUBSTRATUM were added as attributes of the line features based on the matching SITE_ID. Format:The processed data from this study is stored in an Access Database (77 MB). The eAtlas summarised the tow video data into a shapefile [1MB] and CSV files (290 KB). Note the attribute names in the shapefile were truncated to 10 characters due to the limitation of shapfiles.

本大型研究成果发表于Pitcher等人（2007）的研究中，旨在量化大堡礁（Great Barrier Reef, GBR）全域的海底生物多样性模式与礁间环境条件。本研究设定三大核心目标：
1. 评估大堡礁世界遗产区（Great Barrier Reef World Heritage Area）大陆架的海底生物多样性，探究生物物理数据作为生物多样性与底栖群落环境关联因子的应用潜力；
2. 绘制大堡礁区域的兼捕渔获与海底底栖生物群落分布图，以支撑昆士兰州东海岸拖网渔业的环境风险评估与可持续管理工作；
3. 评估声学遥感技术在大堡礁大陆架海底制图以及作为生物多样性替代指标的应用性能。

本研究包含多组大型数据集，基于超过600公里的拖曳式视频采集、约10万张照片、1150段带饵远程水下视频（baited remote underwater videos, BRUVS）、回声测深图、约14000份底栖生物样本、约4000份海底鱼类样本以及约1200份沉积物样本。

电子地图集（eAtlas）已将拖曳式视频数据处理为可用于数据集可视化的shapefile文件（大小为1 MB）。该处理流程通过整合VESSEL_TASKS_ALL表中的拖曳起始与结束事件，生成了名为GBR_CSIRO-AIMS_Seabed-biodiversity-2003-2006_DropCam.shp的shapefile文件与对应的CSV文件（GBR_CSIRO-AIMS_Seabed-biodiversity-2003-2006_DropCam.csv），其中每条航迹对应一个线状要素。随后基于匹配的SITE_ID字段，将VESSEL_VIDEO_BIOHABITAT表与VESSEL_VIDEO_SUBSTRATUM表中的信息作为线状要素的属性字段添加至上述文件中。

本研究的处理后原始数据存储于Access数据库（大小为77 MB）中。电子地图集（eAtlas）将拖曳视频数据汇总为shapefile文件（1 MB）与CSV文件（总大小290 KB）。需注意，由于shapefile格式的字符长度限制，该shapefile中的属性名称被截断为10个字符，完整的属性名称详见下文的数据字典。
