In March-April 1998, the fastest seafloor spreading system, the East Pacific Rise between the Easter and Juan Fernandez microplates was surveyed during a multidisciplinary geophysical/geochemical expedition. Data collected included tows with the DSL-120 kHzsidescan sonar system and tow-yos and vertical casts during the CTD/SUAVE rosette, and co-registered geophysical and geochemical data by mounting the SUAVE in situ chemical analyzer on the DSL-120 depressor weight. This grant will provide funds for reprocessing, analysis, and publication of the DSL-120 sidescan and bathymetry data.

1998年3月至4月，这是最快的海底蔓延系统，在多学科地球物理/地球化学探险期间，对复活节和胡安·费尔南德斯微板之间的东太平洋崛起进行了调查。收集的数据包括在CTD/Suave玫瑰花结构期间与DSL-120 kHzsidescan声纳系统以及Tow-yos和垂直铸件，以及通过在DSL-1220降压器重量上安装Suave Insu situ Chemical Analyzer，并通过安装Suave Insu situ化学分析仪。 该赠款将为DSL-120侧扫描和测深数据的重新处理，分析和出版提供资金。
