Operational Description of the Naval Oceanographic Raw Data Analysis Processing System (NORDAPS)

摘要

The Naval Oceanographic Raw Data analysis Processing System (NORDAPS) is an interactive software package that processes and displays field exercise data. The exercise environmental data is typically obtained from oceanographic platforms using conductivity-temperature-depth (CTD) and/or expendable bathythermograph (XBT) sensors. The data is initially recorded on analog tape, which is then processed by a shore facility that produces the digital data tapes used by NORDAPS. The raw exercise data is read, reformatted, thinned, filtered, and written to direct access data bases. NORDAPS provides an interactive, menu-driven system for analyzing, editing, extracting, plotting and displaying the data. The primary function of NORDAPS is to provide oceanographic input (sound speed profiles) to acoustic models. NORDAPS is used to quality control the raw data, to make appropriate changes, and to create sound speed profiles from shallow data that extend from the surface of the ocean to the sea floor. This document introduces the new user to NORDAPS. It instructs the user on how the system operates and how he can interact with NORDAPS. The manual displays all interactive dialogues and sample plots.
