Abstract

The Nippon Foundation-GEBCO Seabed 2030 Project requires the substantial contribution of crowdsourced bathymetry (CSB) data to help fulfill the aims of this ambitious project to map fully the world's oceans by the year 2030. In this talk, I present efforts from the largest coral reef ecosystem, the Great Barrier Reef (GBR), to map the data gaps through collaborating with partner vessels to collect CSB data, and with funding assistance by the Great Barrier Reef Foundation and support of the Citizens of the Great Barrier Reef.

Preliminary tests with CSB data acquired using a TeamSurv SmartLog data logger on a dive expedition vessel are promising and helps to improve the accuracy of the undersea landscape revealed in the gbr30 grid, a high-resolution grid for the entire GBR. Future work aims to increase the number of SmartLog data loggers installed on collaborating vessels and to expand the contribution of CSB data made publically available to the IHO Data Centre for Digital Bathymetry, the central data repository for the Seabed 2030 Project.
