The Cook Book is a technical reference manual on how to build a bathymetric grid. It was created with the aim of supporting and encouraging further participation in bathymetric grid development work. It was first released in October 2012.

This release includes the following additions.

New chapter added: Chapter 16.0 Finding Gaps to Map

This chapter presents two visualisations to help identify gaps in sounding coverage of the ocean floor as well as a GIS method for prioritising how to fill the gaps. It includes the following sections:
