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%

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%
