Based on a review of observations on different types of calving glaciers, a simple calving model is proposed. Advance or retreat of the calving front is not driven by changes in the calving rate, but by flow-induced changes in the geometry
of the terminal region. This model is essentially different from prior suggestions in which some empirical relation - most commonly the water-depth model - is used to calculate calving rate and the rate of retreat or advance of the terminus.
This article reviews of current understanding of calving processes, and discusses the impact of iceberg calving on glacioclimatic interactions. The dynamics of calving fronts are an important catalyst of change in the hydrosphere and the cryosphere
Further catastrophic break-up of a calving glacier : observations at Austerdalsisen, Svartisen, Norway, 1983-87
Changes of geometry of Austerdalsisen between 1982 and 1987 illustrate the importance of the calving boundary condition in driving glacier flow. Understanding calving is important for management of hydroelectricity power generation schemes
Measuring calving in Icefall Lake, SE Greenland, using a Diver pressure transducer with a built-in datalogger
In South East Greenland, the north-western part of the Mittivakkat Glacier calves into a lake, called Icefall Lake, situated at its terminus. The aim of this study is to test the applicability of the logger in this environment, and to develop
Rapid recent fluctuations of the calving San Rafael glacier, chilean Patagonia : climatic or non-climatic?
In this paper, a link is identified between the oscillation history, the topographic situation and variations in winter precipitation. The influence of calving dynamics has, at differnt times, both damped and amplified the response to climate change
, but the topographic geometry does not permit large-scale, non climatic fluctuations. The Holocene record of glacier behaviour is therefore probably free of calving anomalies.
Taku and Le Conte glaciers, Alaska: calving-speed control of Late-Holocene asynchronous advances and retreats
behavior of the Taku and Le Conte glaciers locates in southeast Alaska. The AA. propose that these asynchronous advances and retreats reflect changes in iceberg calving rates with time.
Calving bays, striae and moraines at Gysinge-Hedesunda, central Sweden
Reconstructions of the retreating margin of the inland ice during the last deglaciation have shown that calving bays or estuaries were frequently formed in subaquatic areas. Such more or less deep bays in the ice margin are indicated by the pattern
inherent in a calving terminus, the interaction of fjord geometry with the extent of the calving terminus, and the intersection of low-lying snow line by a thickening glacier. The Lituya glacier system in southeast Alaska is analyzed with reference
in Tanzania. The four practices are a restricted breeding season, shorter weaning periods for calves, supplemental feeding of weaner calves and a sales policy of unproductive cows. (L'A.).
frequently oscillate, producing pronounced diachronism. Bottom melting removes all debris prior to calving at the ice front so that, ice shelves do not play a part in deposition in the open ocean| 2. Outlet glaciers, in contrast, have high sediment content
, calve rapidly and produce debris-rich icebergs which contribute the major portion of ice-rafted debris.
