Abstract This project will complete the MORVEL models for present day plate motion. MORVEL is a successor to NUVE-1 and NUVEL-1A. The MORVEL data consists almost entirely of spreading rates from marine magnetic anomalies and transform-fault azimuths from marine bathymetric data, and are a significant improvement on prior data sets. Two models will be constructed, one that averages motion over the shortest geological interval possible for a given plate boundary, and a second that uniformly averages motion over the past 3.16 Ma.

摘要 本计画将完成现今板块运动的MORVEL模型。 MORVEL是NUVE-1和NUVEL-1A的后继者。 MORVEL数据几乎完全由海洋磁异常的扩展率和海洋测深数据的转换断层方位角组成，是对先前数据集的重大改进。 将建立两个模型，一个是在给定板块边界的最短地质间隔内平均运动，另一个是在过去3.16 Ma内均匀平均运动。
