Subj: ARCTIC WEST SUMMER 2008 CRUISE REPORT Ref: (a)Polar Icebreaker Cruise Reports, COMDTINST 16155.2B 1.This report is submitted in accordance with reference (a) and covers the period from 06 March 2008 to 15 October 2008.
2.HEALY completed six missions to support Arctic research during the Arctic West Summer 2008 (AWS-08) deployment. The first, second, and third missions, HLY08-01, HLY08-02, and HLY08-03, were conducted in support of the Bering Ecosystem Study, or BEST. This was a study continued from AWS-07 that researched of the effect of climate driven changes on benthic predators in the Northern Bering Sea. HEALY visited over 100 stations between 14 March and 03 May between St. Matthew Island and St. Lawrence Island. The embarked civilian helicopter provided ice reconnaissance, assisted scientists in conducting marine mammal (walrus) and spectacled eiders surveys, and enabled passenger transfers to and from nearby island communities. The third mission of the 2008 deployment, HLY08-03, specifically focused on the summer conditions of the eastern shelf region, ice distribution, and its effects on the ecosystem. This study covered the entire shelf from the Aleutian Islands to St. Lawrence Island. The fourth, fifth, and sixth missions were all in the Arctic, with science parties staging out of Barrow, AK. HLY08-04 heavily focused on the deployment of hydrographic moorings. During HLY08-05, HEALY used the multi-beam sonar and the Knudson sub-bottom profiler to map the 2,500 meter curve of the sea floor in support of extended continental shelf submission under the Convention of the Law of the Sea. The sixth and final mission for AWS 08, HLY-08-06, was a joint operation with the Canadian Coast Guard to collect data in support of delineation of the U.S. and Canadian Extended Continental shelves. HEALY created an ice free channel for the Canadian vessel, Louis S. St. Laurent, to follow while using their multi channel seismic equipment. Following port calls in Kodiak, AK and Ketchikan, AK and a cruise through the scenic Inside th Passage, HEALY returned to ISC Seattle on October 15 .
3.In addition to her assigned scientific missions, HEALY had a Change of Command on June 13, 2008. CAPT T. R. Lindstrom was relieved by CAPT F. J. Sommer.
4.During HLY-08-04 HEALY hosted the Commandant of the Coast Guard, ADM T. Allen and Secretary of Homeland Security, M. Cherthoff.
5.During Arctic West Summer 2008, HEALY transited more than 15,000 nm, providing 157 days of scientific support. All six missions met or exceeded pre-determined research goals, and in many cases yielded significantly more data than scientists had hoped for. With each Arctic

B.Vessel Operations The first notional schedule for the 2008 deployment was developed at the end of September. This schedule followed a Bering Sea Integrated Ecosystem Research Program (BSIERP) and Bering Ecosystem Study (BEST) meeting in Seattle that developed the scope of science funded by the North Pacific Research Board (NPRB) and the National Science Foundation (NSF). This meeting solidified the request of ship time in the Spring and early Summer. The remainder of the schedule was an undetermined mix of speculative work that had yet to be funded by National Oceanic Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS) for the United Nations Law of the Sea (UNCLOS) – Extended Continental Shelf (ECS) efforts and a small Office of Naval Research (ONR) mooring program. The USGS work soon solidified in November after a meeting with the Canadian Coast Guard in Seattle aboard HEALY. The largest issue in completing the 2008 deployment schedule was determining the logistics of four back-to-back Arctic missions. Managing fuel and food were of primary concern. Research of past cruise reports and queries to former HEALY crew members led to a decision not to fuel by barge off Barrow, AK. A limit of 66 days continuous between fueling with an additional restriction of 1% per day average over duration of each mission on fuel consumption was set. An effort, which subsequently worked well, to receive food via C-130 delivery to Barrow and to the cutter by helicopter was planned. Other issues in determining the deployment schedule included managing an even earlier start of science in the Bering for the BEST program, limiting the total number of days away from home port, deciding where and how many days were spent at port calls away from home port, and negotiating how many in port science days were needed by the longer BEST missions. By mid-March, the fifteenth and final draft schedule was produced. The contents of that schedule are contained in Table 1. Only minor deviations, including mid-Summer fueling dates and port calls returning to home port at the end of the season due to the HLY-08-07 cancellation, occurred after March. A more detailed description of the schedule is provided in Appendix 1. A graphical briefing of the schedule is provided in Appendix 2.

Note that there was no OPORD for the spring deployment. Shakedown and Aviation STAN Visit, 1-15 February th st The annual winter dockside availability ended on January 18 . From February 1 th through the 15 HEALY performed its annual shakedown following the winter maintenance availability. The shakedown schedule is contained in Appendix 4. As standard, vendor work acceptance trials were performed, grooms were conducted on various systems, and emergency drills were conducted. Two stops at Port Angeles were performed to transfer passengers. Fuel, from a moored barge, was taken aboard at Manchester. Helicopter training was performed with an Air Station Port Angeles HH-65. In addition, sea surface measurements using a floating thermistor (aka Sea Snake) were taken throughout the trip and near a calibrated reference station in the Strait of Juan de Fuca. Due to an equipment casualty, not all of the winches were tested until the transit for the first science mission. Transit from Seattle to Dutch Harbor, 6 March – 13 March th The transit from Seattle to Dutch Harbor began in the afternoon of March 6 . Just after departing Seattle, HEALY conducted post-repair testing of the Acoustic Doppler Current Profiler (ADCP) between Edmonds and Mukilteo for several hours, followed by boat operations to put a vendor representative ashore at Edmonds. In order to avoid hazardous weather offshore, HEALY proceeded via the Inside Passage to Dixon Entrance. In Dixon Entrance, HEALY conducted a final inspection of the CTD

and rosette. While en route Kodiak Island, HEALY encountered a severe storm with winds greater than 64 knots. One life ring was lost overboard during the transit, which was later found and subsequently made its way to a marine hardware store in Yakutat, Alaska. HEALY had planned to conduct flight training with an Air Station Kodiak HH-60 on March 10th, but the event was cancelled due to pilot illness. Part of the training was later th conducted on March 12 . HEALY completed its transit to Dutch Harbor via a route along the Alaskan Peninsula. HLY-08-01 14-day ‘Early’ Spring BEST (Cooper), 13 March – 26 March The early Spring BEST mission began mobilizing upon HEALY’s arrival in Dutch th Harbor the morning of March 13 . The arrival was scheduled for 0900, approximately 40 minutes before sunrise. In hindsight, the first approach to Dutch Harbor should be made after sunrise to reduce inherent risks from crew rotation. The departure was scheduled for the same day at 1600; however, due to delays in work needed for the cutter, the departure occurred several hours later. The following description provided by the Arctic Icebreaker Coordinating Committee (AICC) summarized the efforts for HEALY’sfirst three missions: The overall goals of the NSF Funded BEST (Bering Ecosystem Study) cruises are to understand the impact of the on-going decrease in seasonal sea ice on the eastern Bering Sea marine ecosystem and how this environmental change might affect subsistence and commercial opportunities in the Bering Sea and local communities. The NSF and the North Pacific Research Board have partnered to support a comprehensive investigation of the Bering Sea ecosystem during 2007-2012. The NSF funded BEST cruises on HEALY will primarily study the nutrients, plankton, and benthos which support upper trophic level animals including fish, whales, birds, walrus, and seals. The specific areas of interest for the early Spring BEST mission were: Benthic sampling with cores, grabs, and a camera; Walrus abundance and tracking with use of a helicopter; Ice biota studies; Plankton sampling with nets; Water column chemistry from bottles, and; Spectacled Eider surveys. Cold temperatures throughout this mission significantly affected science operations. Cold temperatures caused problems with ice accumulation on deck both fore and aft, by freezing seawater in hoses supplying deck and incubator water, and increased exposure
