Because much of the data are legacy in nature, we make no claims to accuracy of the data identification, acquisition parameters, processing methods, navigation, or database entries. We ask that you notify us immediately of any errors or incomplete entries that you discover, and we will make every effort to correct them. We encourage contributions of data and metadata.
The site contains both public and proprietary data. Generally, access to proprietary data is by mutual agreement and depends on terms and conditions of the original acquisition project.
