1: Global Warming?
The WHOI team has joined scientists from Canada, Japan, Alaska, New York, Denmark and China on the Canadian Coast Guard icebreaker Louis S. St-Laurent for this year's expedition to the Beaufort Gyre.
2: Anchors Aweigh
With all 75 officers, crew members and scientists onboard and the final preparations for departure completed, Captain McNeill hoisted anchor and began steaming west towards the Beaufort Gyre.
3: Practice Makes Perfect
The Louis has traversed the Amundsen Gulf and entered the Beaufort Sea. The first CTD casts were taken and the deck crew training began.
4: It's All About the Ice
The icebreaker has now entered the solid icepack, encountering heavy multi-year ice over the CABOS mooring. Chief Scientist Sarah Zimmermann decided to delay the recovery of this mooring until the end of the cruise.
5: Faces of the Louis
In this photo essay, Rick Krishfield shows some of the folks that keep everything shipshape on Canada's largest icebreaker.
6: What a Blast!
In this dispatch, Helen Drost from IOS describes the seismic survey operations being conducted by Canadian and Danish researchers.
7: CTD Nightwatch
Graduate students Jennifer Jackson and Abby Spieler describe their first nighttime CTD cast.
8: Meet and Greet
The scientists and crew enjoy some Louis hospitality on Meet & Greet night.
9: Mooring Day
WHOI mooring expert Will Ostrom describes the recovery of the shallow water Beaufort Slope mooring.
10: Bongos
Jennifer Hutchings from the International Arctic Research Center describes the bongo net tow operation and their catch.
11: Light in the Ocean
Jiuxin Shi from the Ocean University of China discusses his team's research on the physical and optical profiles of Arctic Ocean seawater.
12: Faces of the Louis II
Rick Krishfield shows more photos of the hard-working Louis crew.
13: Murphy's Mooring?
After a long and difficult 12 hour mooring recovery, BGOS Mooring A is safely on deck.
14: The Day After
Rick Krishfield happily reports that a full load of data was retrieved from Mooring A.
15: A Tale of Rosey and the Lab Rats
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.
24: Sonobuoys
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.
35: Little Creatures
Helen Drost describes some of the tiny creatures that the bongo net team has collected.
36: Mooring Levity
Rick Krishfield shares some lighter moments from the mooring operations.
