This study entails processing of Antarctic-Pacific East Pacific Rise (EPR) gravity data with the objective of further developing existing procedures to generate maps of free-air gravity anomalies, Bouguer anomalies and residual gravity anomalies. A profile of gravity anomalies along the entire Pacific-Antarctic EPR will be generated to investigate their relationship to ridge segmentation processes. The availability of swath-mapping data will enhance the subsurface interpretation and lead to a better understanding of accretionary plate boundary at the EPR.

本研究需要处理南极-太平洋东太平洋隆起（EPR）重力数据，目的是进一步发展现有程序，生成自由空气重力异常、布格异常和剩余重力异常的地图。将生成整个太平洋-南极EPR的重力异常剖面图，以研究其与脊分割过程的关系。测绘数据的可用性将增强地下解释，并有助于更好地理解EPR的增生板块边界。
