资源简介:
This data consists of 1867 records derived from 6 tows covering 5.125 km at 2.75m resolution, over a depth range of 59.9 to 45.6 meters. Classification of the benthos and substrate was based on 17 benthic classes and 6 substrate classes.\n\nSummary of the primary benthic categories recorded\nHard Coral 10.44%\nMacroalgae 80.88%\nNoBenthos 5.36%\nOther 3.32%\n\n\nSummary of substrates recorded\nNoSub 10.12%\nRubble 0.37%\nSandCoarse 89.50%\n\nA custom interface has been developed by AIMS staff for reading Towed Video tapes.
本数据集包含1867条记录,源自6次拖曳作业,作业覆盖范围为5.125千米,采用2.75米的空间分辨率,作业水深区间为59.9至45.6米。底栖生物与底质的分类基于17个底栖生物类别与6个底质类别。
已记录的主要底栖生物类别统计如下:
硬珊瑚(Hard Coral):10.44%
大型藻类(Macroalgae):80.88%
无底栖生物(NoBenthos):5.36%
其他(Other):3.32%
已记录的底质类别统计如下:
无底质(NoSub):10.12%
碎石(Rubble):0.37%
粗沙(SandCoarse):89.50%
澳大利亚海洋科学研究所(AIMS)的工作人员开发了一款定制化界面,用于读取拖曳式录像带。
