NdEdit was developed in the Java programming language as a JavaBean software component which allows NdEdit to be incorporated into other Java applications. This paper describes how NdEdit was used to extend two existing stand-alone Java applications; Climate Data Portal and Java OceanAtlas. In Climate Data Portal, NdEdit acts as a data filtering tool for metadata returned from multiple, geographically separated, databases of oceanographic profile and time series data. Java OceanAtlas is an application for visualization of oceanographic vertical sections. In Java OceanAtlas, NdEdit allows data selection and custom section creation of profile data from PMEL's EPIC data archives.
