Data and Reports

This page provides facilities to search for and download data files and reports, etc, from the OS 20/20 Chatham-Challenger survey.

The search facility allows you to enter words to search for, to restrict the list of items to those matching the words you entered. Direct access to the Geonetwork node is available here for an advanced search facility.

A simple browse facility allows you to look through a list of all records in the catalogue, select any items of interest and download any relevant files, or contact the person responsible for these files.
