Autosub Long Range AUV Missions Under the Filchner and Ronne Ice Shelves in the Weddell Sea, Antarctica - an Engineering Perspective

Oceans, 2019
In January 2018, in Cape Town, South Africa, two engineers from NOC Southampton and a scientist from BAS. Cambridge, joined the Alfred Wegener Institute icebreaker RV Polarstern.

Ice sheet margins and ice shelves

1984
The effect of climate warming on the size of ice sheet margins in polar regions is considered. Particular attention is given to the possibility of a rapid response to warming on the order of tens to hundreds of years. It is found that the early response of the polar regions to climate warming would be an increase in the area of summer melt on the ice ...

On meltwater under ice shelves

Journal of Geophysical Research: Oceans, 1995
The basic features of the flow of meltwater under ice shelves can be described by a set of simple relations and length scales. The flow may be divided into two regions, with different basic processes dominating in each. In the first region, melting of the underside of the ice shelf is important and the temperature and salinity of the current tend ...

Arctic Ice Shelves: An Introduction

2017
Ice shelves are relatively thick ice masses that are afloat but attached to coastal land rather than adrift. They form by the seaward extension of glaciers or ice sheets or by build up of multiyear landfast sea ice. They thicken further by surface accumulation of snow and superimposed ice and by accretion of ice from water beneath.

Asymptotic Theories of Ice Sheets and Ice Shelves

2007
In climate dynamics of the Globe the atmosphere, hydrosphere and cryosphere interplay with one another with various different time scales, typically from years to several millennia. Ice sheets and ice shelves, which are the grounded and floating components of the large ice masses such as Greenland and Antarctica and the former Fennoscandinavian and ...

Analytical Models of Ice Sheets and Ice Shelves

2020
Simple mathematical models for ice sheets and ice shelves are described which provide important insights into their dynamics. The models studied can be solved analytically to give equilibrium surface profiles and velocity distributions. Consideration is given to the feedback between surface elevation and mass balance.

Eurasian Arctic Ice Shelves and Tidewater Ice Margins

2017
Despite the presence of about 4000 km of marine-terminating glaciers and ice caps in the Eurasian Arctic, there are few floating ice shelves. Neither are there extensive areas of multi-year shorefast sea ice which might thicken into composite ice shelves themselves.

The Flow of Ice Sheets and Ice Shelves

1993
A brief survey of the mathematical and numerical modelling of ice sheet and ice shelf flows is presented, emphasising the developments over the last decade. For the very slow gravity driven flow of natural ice masses over time scales of thousands of years, the ice is modelled by an incompressible non-linearly viscous fluid with a temperature dependent ...
