9530299 Perfit The Juan de Fuca Ridge has been the site of an extensive study of volcanology and hydrothermal activity. The segment that appears to be most volcanically active (known as the Coaxial segment) has had two eruptions since 1981. The PI has been involved in the collection of basalts from this ridge for several years and wishes to analyze these rocks to investigate the compositions of the lavas and how they change with time. This work would be synthesized into a map that contained the data from the rocks, the hydrothermal vents, and photos.

小行星9530299 胡安·德富卡海岭一直是火山学和热液活动的广泛研究地点。火山活动最活跃的部分（称为同轴部分）自1981年以来已经爆发了两次。PI多年来一直参与从这个山脊收集玄武岩，并希望分析这些岩石，以研究熔岩的成分以及它们如何随时间变化。这项工作将被合成为一张地图，其中包含来自岩石、热液喷口和照片的数据。
