Prof. Tom Weber and grad students Liz Weidner and Erin Heffron sailed aboard New Zealand's R/V Tangaroa where they worked to use echocounders to quanitify the amount of gases coming up form the ocean floor, and to find a way to measure the size and rate of the bubbles.

This video from Seeker, featuring Larry Mayer and the NF-GEBCO Alumni XPRIZE Team, attempts to answer how close we are, how it can happen, and why it matters.

The NOAA Ship Okeanos Explorer's mission, Océano Profundo 2018, is complete. This telepresence-enabled ocean exploration expedition collected critical baseline information on unknown and poorly understood deepwater areas surrounding Puerto Rico and the U.S. Virgin Islands.

The GEBCO-NF Alumni Team accomplished their goals for their field tests in the final round of the Shell Ocean Discovery XPRIZE. They were the first team to go, so now they will wait for the other teams to complete their field demonstrations.

Sound Speed Manager streamlines the use of sound speed profiles in survey acquisition and data processing. The app provides support for commonly-used formats, model-based profile enhancement, and database management with built-in functionalities for analysis and visualization. Sound Speed Manager is an open-source project jointly developed by CCOM and NOAA Coast Survey Development Laboratory.
