"A major benefit of this work is that it provides a testable, tectonic-based model for not only identifying where free hydrogen gas may be forming beneath the seafloor, but also at what rate, and what the total scale of this formation may be, which on a global basis is massive," said [researcher] Lincoln F. Pratson[.]
"Most scientists previously thought all hydrogen production occurs only at slow-spreading lithosphere, because this is where most serpentinized rocks are found. Although faster-spreading lithosphere contains smaller quantities of this rock, our analysis suggests the amount of H2 produced there might still be large," [researcher Stacy] Worman said.
[S]cientists need to understand where the gas goes after it's produced. "Maybe microbes are eating it, or maybe it's accumulating in reservoirs under the seafloor. We still don't know," Worman said. "Of course, such accumulations would have to be quite significant to make hydrogen gas produced by serpentinization a viable fuel source."
Seems like it might be useful for finding downed aircrafts and other missing objects....maybe even people?
Great thought, but the time to process lidar data takes a while. So planes and objects sure, but even the logistics to get this done takes time. Not sure about people, due to resolution over a vast area and again logistics. The bare-earth relief (which strips away a degree of vegetation) lidar offers is incredible. Cartographers and geologist have only recently really taken advantage of the technology. But in time and $, these other uses could definitely be considered, especially when resolution and processing is more developed.
