Alternative fuels and hybrid propul- sion are in its future. “So the way that it works is while it’s submerged, it’s us- ing the batteries for power. Once those batteries run low, the system comes to the surface where it can “breathe” air, and when it can breathe air, it can turn on the generator and that generator then charges those batteries. Once fully charged it dives back down to continue its mission,” said Kauffman.
While the Terradepth team has pro- gressed rapidly, there remain hurdles ahead to accomplish its ultimate mis- sion of dramatically scaling high reso- lution, deep ocean data collection.
“I’m sure most of your readers are familiar with the signal attenuation problem that exists in the ocean,” said
Wolfel. “The reason that we don’t have high resolution bathymetric maps of the
