Revealing Hidden Depths - the Seabed 2030 Podcast
Monthly podcast about the Nippon Foundation - GEBCO 'Seabed 2030' Project - an international project to map the global seafloor by 2030, endorsed as a flagship UN Ocean Decade Programme.
Each month we bring news about the project, interviews with our ocean mapping community and updates about the technology and methods used.

For our first podcast of 2026 we feature an interview with David Bautista of Tcarta, based out of their St John's Newfoundland office where they work closley with the staff of Memorial University, another valued Seabed 2030 Partner.
Contact David at david@tcarta.com and see the Tcarta website here.
David is originally from Colombia, and finds the contrast ith Newfoundland quite noticeable! In the interview he taks about how satellite derived bathymetry (SBD) can play an important role in ocean mapping over shallow, clear, waters where the orbiting sensors can see the seabed well enough to make good estimates of bathymetry. It doesn't work much beyond a few tens of metres depth or in turbid waters, but can add valuable data to the global grid where the conditions are right.
Their homepage describes TCarta's service as "Remote Satellite-Based Hydrospatial Technologies, leveraging a long history of providing bathymetric data and seafloor mapping for marine applications, TCarta offers inland, coastal and offshore hydrospatial and geospatial mapping systems and solutions for geospatial remote sensing intelligence, coastal engineering, environmental and coastal monitoring, and global mapping applications.
Our dedicated team of GIS professionals, hydrographers, imagery analysts, and developers, along with our ecosystem of partner companies, work together to provide full-scope solutions to real world topics in a variety of applications – from engineering and exploration, to navigation and environmental monitoring, and Geospatial Intelligence. We have worked in the coastal waters throughout the globe and with large scale surveying initiatives in the Pacific, Caribbean and Indian Oceans and specific focus on remote island nations and challenging environments in the Middle East and Arctic regions."

Please note that in March we will be attending Economist World Ocean Summit in Montreal, and Oceanology International in London - with a special set of talks from our partners on 11th March. Hopefully see some of our listeners there!
