The "tidewater glacier cycle" is a hypothesized mechanism by which glaciofluvial processes form a proglacial moraine which prevents calving, allowing advance into deep water followed by catastrophic retreat as the moraine degrades, with the process ostensibly continuing ad infinitum. The marine instability hypothesis Many tidewater (and land terminating) glaciers have glacier beds that are overdeepened, that is, the base of the glacier is at a lower elevation upglacier from the terminus.

19.2.8. We propose a simple, highly parameterized model of a tidewater glacier.
We study two cases: (i) a glacier with a specific balance (accumulation) that is spatially uniform, and (ii) a glacier in a warmer climate with the specific balance being a linear function of altitude. This leads to Building on this readvance mechanism, Post (1975) and Meier and Post (1987) suggested the well-known “tidewater glacier cycle” that is characterized by (1) slow advance over several decades to centuries and (2) rapid unstable retreat through basal overdeepening in fjords. Established in 2017, the Walters Kundert Fellowship offers a grant of £10,000 to support research on the physical geography within Arctic and high mountain environments. Links; Humboldt Glacier Retreats; Tidewater Glacier Cycle on Wikipedia; Glaciers, Climate Change, and Sea Level Rise The longest tidewater glacier in Alaska is the Hubbard Glacier which has a calving face over ten kilometres long. In Alaska tidewater glaciers commonly terminate in a vertical face with ice that extends 200-300 feet above the water line and as much as 1000 feet below water. The model is able to simulate the full cycle of ice-free conditions, glacier terminus on land, tidewater glaciers terminus, and backwards. tidewater glacier cycle, and touch on the importance of subaqueous melt.

This project will help to develop a more holistic understanding of the processes controlling tidewater glacier retreats in the long term. The initial thinning or retreat of a tidewater glacier may result from a warming climate, but the extremely rapid retreat thereafter has as much to do with topography and the laws of physics as it does with the current climate.
