    We were able to interview Cousteau’s chief diver, Bernard Delemotte, about the 1975 NASA/Cousteau bathymetry experiment.

    Thanks to the NASA/Cousteau mission, data could be used to calculate water depth and correct outdated nautical charts for shallow waters around the world (where water clarity and seafloor reflectance conditions were sufficient).

    “It was a tremendous example of how modern tools of scientists can be put together to get a better understanding of this globe we live on.” —George Low, 1976 (then-Deputy NASA Administrator) about the NASA/Cousteau Experiment

    The Calypso and Beayondan raced 90 nautical miles each night to be in position, anchored side-by-side, at each of four study sites as the Landsat 1 and 2 satellites flew overhead. The Berry Island study site (lower oval outlined in purple, known as Stations B-1, B-2, F-1), was the primary study site. Just off the coast of Hollywood, Florida (Station D-1) depth measurements were made in waters with less clarity. The whitings investigation took place on the Little Bahama Bank, just north of Grand Bahama (top oval outlined in purple).

    For this experiment, Landsat data was downlinked to NASA Goddard Space Flight Center in Greenbelt, Maryland where it was processed into depth contour data, then uplinked to the Applications Technology Satellite-3 (ATS-3) and then sent via Very High Frequency (VHF) relay to a VHF receiver system that had been installed on the Calypso for an earlier 1974 experiment in the Gulf of Mexico. Modern-day navigation and sea-based communication was portended by the satellite-to-ship information relay demonstrated during the early NASA-Cousteau research. Former NASA scientist, John Barker, shared this memory of the data relay: “By literally hand processing, we managed to turn it around in hours and get it sent to the boat via satellite almost as soon as we finished processing it. In 1975, that was completely unheard of—there was no such thing as ‘real-time’ processing.” Image credit: NASA

This photo was taken near the stern of the Calypso where Cousteau is pointing to a blackboard. In an interview for this story, Delemotte said they were likely discussing the position the Zodiacs needed to be in at the time of the Landsat overpasses.

    In August 1975, Jacques Cousteau, his divers, and a team of scientists set off on an expedition to determine if the young satellites could measure the depth of shallow ocean waters... satellite-derived was born.

    In an early mission, famed aquanaut Jacques Cousteau and astronaut Russell Schweickart teamed up aboard the Calypso to measure water depths as 1 and 2 orbited overhead, paving the way for satellite bathymetry research.
