Okeanos Bound!

8/20/2010 03:11:00 PM

Bon voyage!  I'm off to go explore the seafloor!

Tomorrow I'll get on a plane bound for Guam where I'll rendezvous with the NOAA Okeanos Explorer and catch a ride back to Hawaii on the ship.  The trans-Pacific journey will last 14 days, during which time my job will be to help map the seafloor.  We will travel a 6100 km (3800 mi) great circle path from Guam to Oahu, crossing the Mariana Trench, the abyssal plain, seamounts and ridge systems.  In the process, I'll experience life on the vessel firsthand and report on it here on my blog.

My biggest duty during the EX1005 transit cruise between Guam and Hawaii will be to collect and review high qualify multibeam sonar data as a one of six watchstanders working shifts around the clock to ensure continuous 24x7 mapping along the route.  Two watchstanders will be on duty at all times to cover three 8-hour shifts per day.  I am well-acquainted with watchstanding because that is what I do every week at the NOAA Pacific Tsunami Warning Center.  The photo below shows the control room where I'll be working; there is a good video illustrating how the mapping system works here.

In addition to mapping, the other major activity of this mission will be a continous plankton recorder (CPR) survey conducted by the National Marine Fisheries Service (NMFS).  The Okeanos Explorer ("EX" for short) will tow the CPR device, which collects phytoplankton and zooplankton samples.  This will allow the NMFS to generate reasonable estimates of species occurrence in the upper 10 meters of the water column along the cruise track.

Prior to this cruise leg from June 23 - August 8, The EX completed the INDEX-SATAL 2010 Expedition.  The international mission explored previously uncharted Indonesian waters in the Sangihe Talaud region north of Sulawesi.  The expedition mapped an area the size of Vermont, characterized a 10,000 ft underwater volcano, and discovered 52 new species.  The photo and video footage collected from the expedition are striking and highly recommended.  This part of Indonesia is one of the most biologically diverse areas of the world's oceans, so understanding the ecosystem is important for initiatives such as the Coral Triangle Initiative.

"Understanding what lies beneath the waves enables good stewardship. And healthy oceans enable strong citizens and strong economies."  -- NOAA Administrator Dr. Jane Lubchenco 

The Indonesian mission was also the EX's first wide scale deployment of the ship's telepresence system, which utilizes a powerful V-SAT satellite antenna to broadcast onboard video, images, and other data in real-time to "Exploration Command Centers" (ECC) where researchers, students, and the media can interact live with the crew at sea.  The telepresence strategy allows a wider array of people to partipate, and in fact most scientists work remotely from shore rather than in person aboard the ship.  The flagship ECC is the University of Rhode Island's Inner Space Center.  Other centers are in Seattle, Maryland,  New Hampshire, and Jakarta.

I can't help but wonder why NASA doesn't employ a similar distributed telepresence strategy to engage more "participatory exploration" during its missions.  In fact, one thing that fascinated me about the EX when I first toured it earlier this year was its parallels to space exploration.  It is America's only ship dedicated to systematically exploring the 95% of the ocean that humans have never seen - all in the name of discovery and advancement of knowledge.  I liken the EX's exploration philosophy to planetary exploration: First we send a probe to do initial reconnaissance and mapping.  After scientists review the data and learn more about the planet, they design followup missions with more targeted research objectives.  That's what the EX is doing in the Earth's oceans.

The video gives a really nice overview of the Okeanos Explorer in more detail.

That's a terrific job opportunity Brian, a really important addition to a C.v. Recent data has shown world plant growth and life to be receding and the opportunity to map photoplanton regions and begin constant monitering at sea level will be vitally valuable to better comprehension of atmospheric science.

I wonder if the log will record wind speed and direction as I beleive that the empiracle science is with the microbiopic ability to spread planton molecules that have been purged of salt to land, giving land flora more opportunity to flourish, the data showing world plant receding could correlate to more category 5 hurricanes that recent years have produced.

Saying that, the world could be witnessing the coming of a macrobiopic entity or species as a result of a larger weather cycle patterns of interaction between micro and macro life forms!

Invasion of humans???


Good luck.
