SUMMARY:Marine Science Center Lecture - Humpback Whales Generate “Thrums
 ”
DESCRIPTION:The Port Townsend Marine Science Center (PTMSC) is pleased to w
 elcome whale biologist Dr. Fred Sharpe to its “Future of Oceans” lectu
 re series on Sunday\, November 16\, 3 p.m.\, at the Wheeler Theaterin Fort
  Worden Historical State Park. Humpback whales produce varied aerial sound
 s including trumpets\, shrikes\, hoots and percussions. Of special interes
 ts are their low frequency\, far-traveled\, elephant-like\, aerial rumbles
 . Although “thrums” are new to science\, they are familiar to those in
  the Salish Sea. The lecture will feature sounds\, slides and the scientif
 ic inquiry conducted at Five Finger Lighthouse into these remarkable aeria
 l signals. Fred Sharpe has been studying the foraging ecology of humpback 
 whales in SE Alaska since 1987. He received his Ph.D. from Simon Fraser Un
 iversity and is currently an affiliate with the SETI Institute\, a Co-Inve
 stigator with the Whale-SETI Study Team and a Principal Investigator with 
 the Aerial Signals Project. Using the humpback whale as an alien analog\, 
 Fred and his colleagues employ an astrobiological framework including SETI
  (Search For Extraterrestrial Intelligence) which involves humpback call c
 lassification and analysis using information theory; METI (Messaging) whic
 h involves dynamic playbacks to establish whale-human acoustic interaction
  and RETI\, responding to volitional overtures toward humans “candidate 
 signals -bubble rings and other effervescent structures. These studies ill
 uminate the biotic variables of the Drake Equation\, and suggest that the 
 lack of cosmic signal detection may partially be perceptual in nature. Fre
 d’s interest in conservation biology has led him to follow the whales so
 uth to their Hawaiian wintering to document their historical ecology and l
 egacy impacts from commercial whaling. He has been awarded the Fairfield A
 ward for Innovative Marine Mammal Research and the Society for Marine Mamm
 ology’s Award for Excellence in Scientific Communication. Fred volunteer
 s with NOAA as a large whale entanglement responder. He is also a co-autho
 r of Voyaging with the Whales which celebrates Alaska’s humpback whale b
 ubble netting culture. All events are free. Donations are welcomed and app
 reciated. Since its inception in 2014\, the PTMSC Future of Oceans lecture
  series has explored the frontiers of ocean research and emerging technolo
 gies while confronting the human capacity to understand and sustain health
 y oceans. Each year attendees are challenged and informed with thought-pro
 voking presentations. The series is made possible by the generous support 
 of the Darrow family. For more information about the lecture series\, visi
