阿西达里亚海区

阿西达里亚海区^[1]（英語：Mare Acidalium quadrangle）是美国地质调查局太空地质学研究计划（Astrogeology Research Program）对火星表面划分的30个区域之一，编号为MC-3。阿西达里亚海区位于火星西半球的东北部，覆盖了火星东经300°至360°（西经0°至60°）、北纬30°至65°的区域。该区域使用1:5,000,000比例尺的朗伯等角圆锥投影。^[2]

阿西达里亚海区的南北边界分别为大约3,065公里与1,500公里宽，南北距离则为约2,050公里。^[3]覆盖范围约为490万平方公里，占火星表面积的3%以上。^[4]
