Browse Shelf Reef Polygons

Browse Shelf reef polygons were manually digitized from multibeam echosounder datasets collected on marine survey GA0345/GA0346/TAN1411 in October/November 2014. Reef areas were defined as exposed, hard substrate that are often raised above the surrounding seafloor. The continental shelf was defined using the 200 m depth contour. They were mapped using bathymetry and backscatter data along with bathymetric derivatives including; slope, hillshaded bathymetry and contours. Features were mapped at a scale of 1:10 000.

布劳斯陆架礁多边形数据集由2014年10月至11月开展的海洋调查GA0345/GA0346/TAN1411所采集的多波束测深数据集（multibeam echosounder datasets）经手动数字化生成。礁体区域被定义为常抬升于周围海底之上的裸露硬质底质；大陆架以200米等深线作为划分标准。本次要素制图结合了水深数据、背散射数据以及坡度、晕渲水深图、等深线等水深衍生数据完成，制图比例尺为1:10000。本数据集经澳大利亚地球科学局（Geoscience Australia）首席执行官授权发布。
