  • The South Polar Race Medal
    The South Polar Race Medal Created by Danuta Solowiej The way to the South Pole / Sydpolen. Roald Amundsen’s track is in Red and Captain Scott’s track is in Green. The South Polar Race Medal Roald Amundsen and his team reaching the Sydpolen on 14 Desember 1911. (Obverse) Captain R. F. Scott, RN and his team reaching the South Pole on 17 January 1912. (Reverse) Created by Danuta Solowiej Published by Sim Comfort Associates 29 March 2012 Background The 100th anniversary of man’s first attainment of the South Pole recalls a story of two iron-willed explorers committed to their final race for the ultimate prize, which resulted in both triumph and tragedy. In July 1895, the International Geographical Congress met in Lon- don and opened Antarctica’s portal by deciding that the southern- most continent would become the primary focus of new explora- tion. Indeed, Antarctica is the only such land mass in our world where man has ventured and not found man. Up until that time, no one had explored the hinterland of the frozen continent, and even the vast majority of its coastline was still unknown. The meet- ing touched off a flurry of activity, and soon thereafter national expeditions and private ventures started organizing: the Heroic Age of Antarctic Exploration had begun, and the attainment of the South Pole became the pinnacle of that age. Roald Engelbregt Gravning Amundsen (1872-1928) nurtured at an early age a strong desire to be an explorer in his snowy Norwegian surroundings, and later sailed on an Arctic sealing voyage.

    olivine-rich intrusive is dominant in the westernmost part of the mountains. In the east, a small isolated outcrop consisted of sedimentary rocks in a sequence of about 50 m, containing a fossil Glosopteris flora of Permian age. All mountains were crossed by do- lerite sills and dykes. Astronomical observations of the sun and stars were made to get an exact location of the mountains; for elevation estimation, a series of pressure readings will be compared with contemporaneous ones from SANAE and Halley Bay. Measurements of the mag- netic field were also made. During work in the moun- tains, animal and plant life were observed, and some samples were taken. In January, the glaciologist travelled 70 km north to the ice shelf, where a snow pit was dug and core drillings were made in order to compare the condi- tions there to those at the main base. Facilitated by favorable conditions, the work was finished ahead of schedule. Owing to coarse sastrugi and soft snow, the LC-130 aircraft experienced difficulty in becoming airborne, but succeeded after climbing up a slope and taking off downhill.

  • Living and Working at USAP Facilities
    Chapter 6: Living and Working at USAP Facilities CHAPTER 6: Living and Working at USAP Facilities McMurdo Station is the largest station in Antarctica and the southermost point to which a ship can sail. This photo faces south, with sea ice in front of the station, Observation Hill to the left (with White Island behind it), Minna Bluff and Black Island in the distance to the right, and the McMurdo Ice Shelf in between. Photo by Elaine Hood. USAP participants are required to put safety and environmental protection first while living and working in Antarctica. Extra individual responsibility for personal behavior is also expected. This chapter contains general information that applies to all Antarctic locations, as well as information specific to each station and research vessel. WORK REQUIREMENT At Antarctic stations and field camps, the work week is 54 hours (nine hours per day, Monday through Saturday). Aboard the research vessels, the work week is 84 hours (12 hours per day, Monday through Sunday). At times, everyone may be expected to work more hours, assist others in the performance of their duties, and/or assume community-related job responsibilities, such as washing dishes or cleaning the bathrooms. Due to the challenges of working in Antarctica, no guarantee can be made regarding the duties, location, or duration of work. The objective is to support science, maintain the station, and ensure the well-being of all station personnel. SAFETY The USAP is committed to safe work practices and safe work environments. There is no operation, activity, or research worth the loss of life or limb, no matter how important the future discovery may be, and all proactive safety measures shall be taken to ensure the protection of participants.
