Kristina Brown and Mary Steele wax poetic.
|16: Grin and Bear It|
While temporarily halted for repairs, a curious polar bear visits the Louis.
|17: Science Program|
Chief Scientist Sarah Zimmermann explains the conductivity-temperature-depth (CTD) instrument.
|18: Phytoplankton Food|
Linda White talks about why she is collecting nutrient data and how it relates to the growth of tiny ocean plants.
|19: Faces of the Louis III|
The Louis is back underway! Rick Krishfield's photo essay of Louis crew members continues in this dispatch.
|20: Back to (Mooring) Work|
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.
The Louis cruises northward through unusually ice-free conditions, allowing the NRCan team to study the sediments below.
|25: Ice Recon|
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.
|34: An ITP and a BBQ|
The mooring crew successfully installs another ice-tethered profiler and the ship celebrates the (almost) completion of the cruise with a barbeque.
