Merry Christmas

The autonomous underwater vehicle (AUV) Sentry got a festive “makeover” aboard R/V Atlantis this month—WHOI engineer Justin Fujii used electrical tape and a little magic to make the AUV resemble a certain jolly old elf. Scientists from the University of Alaska Fairbanks, University of California Santa Cruz and Moss Landing Marine Laboratory deployed Sentry and the remotely operated vehicle (ROV) Jason to sample fluid emitted from a hydrothermal system called the Dorado Outcrop on a three-week cruise off Costa Rica. Atlantis returned with “Santa Sentry” to Costa Rica December 23, just in time for Christmas.(Photo by Allison Heater, Woods Hole Oceanographic Institution)
