The major objectives of the proposed study are the systematic investigation, description, and mapping of morphologic features on the surface of Mars. In particular, we propose to study degraded flow features and cones in the Acidalia Planitia region. The location of such features is indicative of the distribution of mud volcanism and its related reservoirs that are plausibly related to the existence of a north-polar ocean in Martian history. We will specifically address the following scientific questions: Does the observed surface morphology support the existence of a standing body of water in the northern Martian hemisphere? Is the morphology consistent with a northern hemisphere ocean or is it rather consistent with several individual seas? Is there a common origin of the morphologies (i.e., mud flows, polygonal terrain, thumbprint terrain, ghost craters, rampart craters) observed in Acidalia Planitia and similar morphologies observed in Utopia and Isidis Planitiae? If so, were they all formed by the same standing body of water?

这项研究的主要目标是对火星表面的形态特征进行系统的调查、描述和测绘。特别是，我们建议研究Acidalia Planitia地区退化的流动特征和锥体。这些特征的位置表明了泥火山活动及其相关储层的分布，这些储层似乎与火星历史上北极海洋的存在有关。我们将具体解决以下科学问题：观察到的地表形态是否支持火星北半球存在常水体？它的形态与北半球的海洋相一致，还是与几个单独的海洋相一致？在Acidalia Planitia和Utopia和Isidis Planitiae中观察到的相似形态（即泥流、多边形地形、指纹地形、幽灵陨石坑、堡垒陨石坑）是否有共同的起源？如果是这样的话，它们都是由同一个静止的水体形成的吗？
