Kris Newhall, WHOI mooring technician, describes the process of deploying one of the 2-mile long BGOS subsurface moorings. |
 | 21: Tiny Torpedoes
Shigeto Nishino of JAMSTEC talks about the expendable CTD, a small torpedo-like instrument used to measure water temperature and salinity. |
 | 22: Hump Day
It's the halfway point of the cruise, but much work remains to be done. |
 | 23: Captain's Table
A traditional supper at the Captain's Table is the highlight of a Sunday on the Louis. |

Rick Krishfield takes a ride on the ship's helicopter in search of multi-year ice for an ice-tethered profiler deployment site. |
 | 26: Faces of the Louis IV
The Louis has made excellent time through light ice to the second WHOI mooring location and recovered the precious instruments. |
 | 27: Mooring Ops - View from the Bridge
Chief Scientist Sarah Zimmermann describes a subsurface mooring recovery from the bridge team's perspective. |
 | 28: White Out
The science party braves whiteout conditions on the ice to make measurements of ice optics and thickness. |
 | 29: A Long Day
A marathon day for the mooring crew results in the successful deployment of Mooring B and an ice-tethered profiler. |
 | 30: Foul Weather
The clear weather of the previous day is replaced by a fierce autumn storm. |
 | 31: Ice-Based Observatory
The science team installs a cluster of ice-tethered instruments on a thick multi-year ice floe. |
 | 32: Importance of Oceanographic Research
Mike Dempsey discusses the value of "being there." |
 | 33: Faces of the Louis V
Rick honors another group of Louis crewmembers in his photo essay series. |
