This voyage visited Mawson and Davis, leaving from and returning to Hobart. From the voyage leader's report:The first voyage of the 1992-93 season left Hobart on 17 October on board the Aurora Australis for Mawson and Davis Ice Edges, and Sea Ice Program research activities in the Prydz Bay region. On board were a total of 97 expedition personnel, including 44 for Mawson, 42 for Davis and 11 round trippers.The journey to the ice edge north of Mawson took just over 16 days, primarily because of particularly heavy ice conditions in the approach to Mawson and bad weather. On the morning of the 31 October, a blizzard forced the ship to stop in the ice as visibility was less than a few hundred metres in driving snow. The barometer reached its lowest ever recording on Aurora to that time, 940.6 Hpa, although the wind only reached 55 knots in gusts.When conditions improved, the ship proceeded again and finally reached the fast ice edge 55 km north of Mawson on the morning of 2 November. Just over three days were spent at the ice edge, the period being marked by frequent periods of low cloud and whiteout. All required personnel were transferred to and from the ship and nineteen huskies bound for the United States were taken on board. The limited opportunities for aircraft operations and the very poor condition of the Mawson-ship fast ice route resulted however in only very high priority cargo being delivered to the station.The vessel departed the Mawson ice edge on the afternoon of 5 November, working its way north then east in to Prydz Bay. Heavy ice conditions continued to be experienced, and this coupled with poor visibility and large amounts of snow lying on the ice (both which considerably restricted the ability to choose the best route through the ice), made progress slow. Some two days were spent in Prydz Bay conducting sea ice research, including the deployment of two buoys, and the Aurora reached the ice edge off Davis on the morning of 10 November.The ship took almost twelve hours to break through the heavy fast ice present at Davis to reach the optimum position for the pumping of station fuel ashore. A large amount of dry cargo was discharged over two days and the majority of RTA cargo awaiting on the station (mainly rubbish) back-loaded. Aurora left the ice edge at Davis on the afternoon of 12 November and after pushing north through, at times, heavy pack ice, the voyage to Hobart was smooth, and the vessel reached there late on the afternoon of 23 November.Progress Code: completedStatement: Please see the Marine Science Support Data Quality Report via the Related URL section.

Full description

This dataset contains the underway data from Voyage 1 1992-93 (MONGREL) of the Aurora Australis. This voyage visited Mawson and Davis, leaving from and returning to Hobart.

From the voyage leader's report:

The first voyage of the 1992-93 season left Hobart on 17 October on board the Aurora Australis for Mawson and Davis Ice Edges, and Sea Ice Program research activities in the Prydz Bay region. On board were a total of 97 expedition personnel, including 44 for Mawson, 42 for Davis and 11 round trippers.

The journey to the ice edge north of Mawson took just over 16 days, primarily because of particularly heavy ice conditions in the approach to Mawson and bad weather. On the morning of the 31 October, a blizzard forced the ship to stop in the ice as visibility was less than a few hundred metres in driving snow. The barometer reached its lowest ever recording on Aurora to that time, 940.6 Hpa, although the wind only reached 55 knots in gusts.

When conditions improved, the ship proceeded again and finally reached the fast ice edge 55 km north of Mawson on the morning of 2 November. Just over three days were spent at the ice edge, the period being marked by frequent periods of low cloud and whiteout. All required personnel were transferred to and from the ship and nineteen huskies bound for the United States were taken on board. The limited opportunities for aircraft operations and the very poor condition of the Mawson-ship fast ice route resulted however in only very high priority cargo being delivered to the station.

The vessel departed the Mawson ice edge on the afternoon of 5 November, working its way north then east in to Prydz Bay. Heavy ice conditions continued to be experienced, and this coupled with poor visibility and large amounts of snow lying on the ice (both which considerably restricted the ability to choose the best route through the ice), made progress slow. Some two days were spent in Prydz Bay conducting sea ice research, including the deployment of two buoys, and the Aurora reached the ice edge off Davis on the morning of 10 November.

The ship took almost twelve hours to break through the heavy fast ice present at Davis to reach the optimum position for the pumping of station fuel ashore.
