Healy on the Bering Sea
U.S. Coast Guard Cutter Healy is sailing north through the Bering Sea, headed for the Bering Strait. Ship icon shows the vessel’s approximate location as I write (Tuesday morning, August 3). We’ll be much farther north by the time you read this! Click image for larger view.

Healy docked in Dutch Harbor. The fog in the background is typical, and occasionally so thick that flights from Anchorage have to turn around and go back without landing. Click image for larger view. Credit: Helen Gibbons, USGS/ECS Project

We’re off! The U.S. Coast Guard Cutter Healy has come to life and is moving gently with the swells as we sail north through the Bering Sea. Right now we are on a transit from Dutch Harbor, Alaska, to our rendezvous with the Canadian Coast Guard Ship Louis S. St-Laurent, aka Louis (pronounced “Louie”), in the Arctic Ocean north of Canada’s Mackenzie River delta. In good visibility and mild (2- to 4-foot) seas, the ship is making about 16 knots (18 mph). At times, turbine engines wind down as fog slows our speed to less than 10 knots (11 mph). So far, it’s a smooth ride.
During previous joint Arctic mapping missions (2008 and 2009), members of the science crew were helicoptered onto Healy from the town of Barrow on Alaska’s Arctic coast. For this year’s mission, we met the ship in Dutch Harbor, the site of a military base built during World War II and now a large fishing port in the eastern Aleutian Islands. “Dutch,” as it is generally known, was chosen as a convenient place to embark scientific personnel, refuel, and reprovision after two long previous missions.
Dutch is situated on Amaknak Island, which is virtually surrounded by the much larger Unalaska Island. The city of Unalaska, of which Dutch is a part, grew from an Aleutian settlement on the larger island. Many of us arrived a day or two early and enjoyed exploring local attractions, such as the Museum of the Aleutians, a Russian Orthodox church built in Unalaska in 1825, and the remnants of bunkers and other military installations on Amaknak. The steep mountains mantled in soft green vegetation—plus the absence of bears, snakes, ticks, and poison oak—made hiking especially appealing.

A few of us took a hike up Mount Ballyhoo on Amaknak Island. Here near the top is Peter Triezenberg, U.S. Geological Survey geologist who will be processing gravity data and chirp seismic-reflection data during the mission. Some of the port facilities of Dutch Harbor are visible to the left of Peter. The mountains in the background are on Unalaska Island, a much larger island that virtually surrounds Amaknak.

We unmoored and departed shortly after 3 p.m. yesterday, and as I write, we have come more than 250 nautical miles north-northeast and are approximately at latitude 58°N and longitude 168°W. We’ll spend about 5 days in transit, passing through the Bering Strait, across the Arctic Circle, and through the Arctic Ocean to our rendezvous with Louis. The transit will give us a little extra time to become familiar with the ship (I’m still getting lost in the maze of passageways!), learn more about our scientific duties, and get better acquainted with our shipmates. Now that we’re aboard, we’ve shared lots of meals in the mess, had orientation and safety meetings with the Coast Guard crew, and held our first scientific meeting. The Coasties are extremely capable, friendly, and supportive, and the scientific crew is almost scary in its collective knowledge and experience of all the topics we intend to study. Everyone’s fired up, and it’s great to be underway!

Conning officer Nick Custer (in doorway, monitoring the ship’s position as it moves away from the dock in Dutch Harbor) calls commands to helmsman Dierdre Gray (far right), who repeats and executes each command. Only two or three watchstanders are required when the ship is underway, but the bridge is busy with additional personnel during arrivals and departures. Click image for larger view.
