Filling the data gaps

What is CSB?

Crowdsourced bathymetry (CSB) is the collection and sharing of depth measurements from vessels, using standard navigation instruments, while engaged in routine maritime operations.

Crowdsourcing is a powerful approach that leverages the collective efforts of a diverse community to gather and contribute data. It involves engaging scientists, researchers, and enthusiasts in the active participation of data collection, democratizing and fostering collaboration.

Bathymetry, a fundamental aspect of oceanography, focuses on measuring and mapping the topography of the ocean floor. It encompasses the study of underwater depths, contours and features, providing crucial insights into seafloor structures, canyons and ridges. Bathymetry is vital for understanding marine ecosystems, geological processes and identifying potential resource locations.

The combination of crowdsourcing and bathymetry creates an unprecedented opportunity to contribute to ongoing efforts to achieve a comprehensive and detailed map of the ocean floor. By involving a wide range of contributors, including research vessels, autonomous underwater vehicles, and recreational sailors, vast areas of coastal waters and the the ocean can be covered. This collaborative approach generates high-resolution bathymetric maps that unlock valuable insights into marine environments, facilitating scientific discoveries with far-reaching implications for conservation, resource management and our overall understanding of the world's oceans.
