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，在一次多学科地球物理/地球化学考察期间，对复活节和胡安费尔南德斯微板块之间的东太平洋海隆这一海底扩张最快的系统进行了调查。收集的数据包括使用DSL-120 kHz侧扫声纳系统的拖曳以及CTD/SUAVE玫瑰花形期间的拖曳和垂直抛掷，并通过将SUAVE现场化学分析仪安装在DSL-120抑制器砝码上共同记录地球物理和地球化学数据。 这笔赠款将为DSL-120侧扫和测深数据的再处理、分析和出版提供资金。
