资源简介:
This data consists of 25752 records derived from 63 tows covering 36.114 km at 1.40m resolution, over a depth range of .9 to 18.1 meters. Classification of the benthos and substrate was based on 17 benthic classes and 6 substrate classes. Summary of the primary benthic categories recorded Gorgonians 0.98% Hard Coral 11.57% Macroalgae 7.78% NoBenthos 39.82% Seagrass 16.32% Other 23.50% Summary of substrates recorded Rubble 0.63% NoSub 0.88% Rock 13.64% Sand 25.38% Silt 27.55% Sludge 5.91% Mud 23.23% Stone 1.30% SandCoarse 1.44% A custom interface has been developed by AIMS staff for reading Towed Video tapes.

本数据集包含25752条记录,源自63次拖曳作业,覆盖总长度36.114千米的调查区域,空间分辨率为1.40米,作业水深范围为0.9至18.1米。底栖生物(benthos)与底质(substrate)的分类基于17个底栖生物类别及6个底质类别开展。 已记录的主要底栖生物类别统计如下: 柳珊瑚(Gorgonians):0.98% 硬珊瑚(Hard Coral):11.57% 大型藻类(Macroalgae):7.78% 无底栖生物(NoBenthos):39.82% 海草(Seagrass):16.32% 其他(Other):23.50% 已记录的底质类别统计如下: 碎砾(Rubble):0.63% 无底质(NoSub):0.88% 岩石(Rock):13.64% 沙(Sand):25.38% 粉砂(Silt):27.55% 污泥(Sludge):5.91% 淤泥(Mud):23.23% 石块(Stone):1.30% 粗砂(SandCoarse):1.44% 澳大利亚海洋科学研究所(AIMS, Australian Institute of Marine Science)工作人员已开发定制化界面,用于读取拖曳式视频(Towed Video)录像带数据。
