AbstractSLAR imagery of Nares Strait was obtained on three flights carried out in. January, March, and August of 1973 by Canadian Forces Maritime Proving and Evaluation Unit in an Argus aircraft equipped with a Motorola APS-94D SLAR; the March flight also covered two lines in the Arctic Ocean, from Alert 10 the North Pole and from the Pole down the long. 4ºE. meridian to the ice edge at about lat. 80º N. No observations on the ground were possible, but -some back-up was available on all flights from visual observations recorded in the air, and on the March flight from infrared line-scan and vertical photography.The interpretation of ice features from the SLAR imagery is discussed, and the conclusion reached that in spite of certain ambiguities the technique has great potential which will increase with improving resolution, Extent of coverage per distance flown and independence of light and cloud conditions make it unique among airborne sensors.

Ice Model

The Sea-Ice Model Intercomparison Project (SIMIP) is part of the activities of the Sea Ice-Ocean Modeling Panel (SIOM) of the Arctic Climate System Study (WMO) (ACSYS) that aims to determine the optimal sea-ice model for climate simulations. This investigation is focused on the dynamics of sea ice. A hierarchy of four sea-ice rheologies is applied, including a viscous-plastic rheology, a cavitating-fluid model, a compressible Newtonian fluid, and a simple scheme with a step-function stoppage for ice drift.For comparison, the same grid, land boundaries and forcing fields are applied to all models. Atmospheric forcing for a 7 year period is obtained from the European Centre for Medium-Range Weather Forecasts (UK) (ECMWF analyses), while occanic forcing consists of annual mean geostrophic currents and heal fluxes into a fixed mixed layer. Daily buoy-drift data monitored by the International Arctic Buoy Program (IABP) and ice thicknesses at the North Pole from submarine upward-looking sonar are available as verification data. The daily drift statistics for separate regions and seasons contribute to an error function showing significant differences between the models. Additionally, Fram Strait ice exports predicted by the different models are investigated. The ice export of the viscous-plastic model amounts to 0.11 Sv. when it is optimized to the mean daily buoy velocities and the observed North Pole ice thicknesses. The cavitating-fluid model yields a very similar Fram Strait outflow, but underestimates the North Pole ice thickness. The two other dynamic schemes predict unrealistically large ice thicknesses in the central Arctic region, while Fram Strait ice exports are too low.

AbstractThe Transglobe Expedition (leader Sir Ranulph Fiennes, Bt.), circumnavigated the world between September 1979 and 1982, keeping as close as possible to the Greenwich meridian. This involved journeys in both polar regions. During the expedition's southern phase (1979–81) two overwintering bases were established in Antarctica and a party of three crossed the icecap on snowmobiles, via the South Pole. During the northern phase (1981–83) two men traversed the Northwest Passage by boat on foot, sledging across Ellesmere Island to the settlement of Alert, where a party of three overwintered. Two then set out over the pack ice, crossing the North Pole and drifting with the floating ice toward Svalbard, to be picked up by the expedition ship.

First Time

ABSTRACTHaving spent 21 months on board their icebound ship, Tegetthoff, adrift in the pack ice to the north of Novaya Zemlya, and having explored a substantial part of Zemlya Frantsa-Iosifa [Franz Josef Land], to which the ice-drift had carried their ship, on 20 May 1874 the members of the Austro-Hungarian North Pole expedition abandoned it and started south by sledge and boat. Progress was painfully slow, and for weeks involved repeatedly alternating between man hauling across floes and rowing or sailing across leads and polynyas. The expedition finally reached open water on 15 August and started rowing and sailing south along the west coast of Novaya Zemlya. They encountered two Russian fishing boats at Mys Britvin [Cape Britvin], just south of Matochkin Shar on 24 August, and the Austrians persuaded one of their captains to take them to Vardø in Northern Norway. They arrived there on 3 September and caught the mail steamer south to Hamburg. Apart from the engineer, Otto Krisch, who died of tuberculosis and scurvy and was buried on Ostrov Vilcheka [Wilczek Island], the remaining 24 members of the expedition returned home safely. The diary of one of the co-leaders of the expedition, Lieutenant Carl Weyprecht, covering the period of the retreat, is published here in English for the first time.
