Image of The Day caption:
Don Koelsch (far left) and other WHOI engineers and seismologists with the Near Ocean Bottom Explosives Launcher (NOBEL) system on the fantail of R/V Atlantis II in 1991. Koelsch helped develop the NOBEL system, which was the first system to successfully detonate multiple high-explosive charges at full ocean depths. The energy generated by these precisely-detonated explosions can be detected by seismometers, allowing geologists to see below the seafloor to Earth s crustal structure. Koelsch passed away in January. Also pictured (left to right): MIT graduate student John Olson, WHOI research assistant Rob Handy, University of Hawaii scientist Gerard Fryer, and WHOI research associates Jim Broda and Beecher Wooding.
