| Antarctic Circle | |
 |
The Antarctic Circle is one of the five major circles of latitude that mark maps of the Earth. These are The Equator, Tropic of Cancer & Capricorn, Artic & Antarctic Circle. The Antarctic Circle is an imaginary line that encircles the South Pole at latitude 66° 33’ S. The line encompasses the continent of Antarctica and the Antarctic Ocean. |
The region south of this line experiences at least one night in the southern summer during which the Sun never sets, and at least one day in the southern winter during which the Sun never rises. This is because the earth is tilted at a 23.5 degree angle, and during the winter solstice, the northern hemisphere is tilted away from the Sun, meaning that the antarctic circle is completely tilted towards the Sun, hence it experiences 24 hour daylight, and vice versa. This time period increases as one aproaches the South Pole until at the South Pole there are six months of daylight during summer and six months of night during winter. |

| Law Dome Traverse | |
| Two Trips to Law Dome were completed this month this month.The dome is a 200 km wide and 1400 m high mound of ice 120kms and 2 days traverse southeast of Casey. It continues to be the focus of considerable glaciological interest and research, and also has our aircraft landing sites on its eastern side. | |
| The first team to go to the summit earlier this month was led by Cathie and included Clinton, John and Jim. On their way to the Dome, they re-erected the Antarctic Circle sign. At the summit they serviced and raised above the ever-accumulating snow an automatic weather station that is important to weather forecasting and therefore to air transport operations. Unfortunately they were prevented from reaching another weather station further to the east by deep fresh snow that threatened to bog their vehicles |
|
| The second party comprising
Noel, Clinton, Barry, Chris and Eve in three vehicles is establishing
a camp for an ice drilling project, led by Andrew Smith of ANSTO,
Sydney, with fieldwork to be completed in November.
A secondary project in addition to the camp placement involves testing a system of e-mail transmission by remote field parties using HF radio. |
