The Engineers
Unsung heroes & heroines, without whom, nothing works. All of the engineers work on whatever needs doing at any particular moment, but here’s a list of their known roles on this voyage:
![]() |
Kim Reisenbichler, MBARI marine biologist and research technician, helped develop and put together the RC airplane for iceberg tagging & reconnaissance and is one of its pilots. |
![]() |
Jake Ellena, MBARI research technician, can keep any piece of machinery working, and knows an Echinocrepis rostrata when he sees one, too. |
![]() |
Paul McGill, MBARI electrical engineer, working on the Onscreen Display for the RC airplane, the tiny computer & software that the plane and its pilots to navigate. Also works on the ROV. |
![]() |
Rob Sherlock, MBARI research technician and marine biologist, helping with the ROV, sampling mechanisms & cameras. Also an excellent diver. |
![]() |
Dr. Alana Sherman, MBARI electrical engineer, working on the ROV & Lagrangian traps. |
![]() |
Brett Hobson, MBARI mechanical engineer, working on the mechanical systems for the Phantom ROV and sonar. |
![]() |
Mark Talkovic, MBARI pilot, mainly of ships and remotely operated vehicles. On this voyage, he will pilot the Phantom ROV. |
![]() |
Steve Etchemendy, MBARI marine operations director (and NancyE’s bro-in-law), heading up the RC airplane team and will help keep the ROV working. |
![]() |
Joanna O’Neill, Sonar Technician working with Steve Rock on multi-beam echosounder. |
![]() |
Adam Jenkins, Raytheon Polar POC (point of contact), our liaison with Raytheon, handling logistics, which means, basically, everything. |
![]() |
Nancy Etchemendy yours truly, ship’s horror writer (hard to pigeon-hole, so I just put myself here in sheer desperation). |
Ship’s Officers
![]() |
Captain Mike Watson For the longest time, I didn’t know his last name. His shirt just says “Captain Mike.” Definitely the skipper. |
![]() |
First Mate Rachelle Captain Mike’s right-hand woman. |
Those on Shore
Not everyone is lucky enough to be on the icebreaker. Some will do their part from shore.
