Channelized Ice Melting in the Ocean Boundary Layer Beneath Pine Island Glacier, Antarctica

Abstract: Ice shelves play a key role in the mass balance of the Antarctic ice sheets by buttressing their seaward-flowing outlet glaciers; however, they are exposed to the underlying ocean and may weaken if ocean thermal forcing increases. An expedition to the ice shelf of the remote Pine Island Glacier, a major outlet of the West Antarctic Ice Sheet that has rapidly thinned and accelerated in recent decades, has been completed. Observations from geophysical surveys and long-term oceanographic instruments deployed down bore holes into the ocean cavity reveal a buoyancy-driven boundary layer within a basal channel that melts the channel apex by 0.06 meter per day, with near-zero melt rates along the flanks of the channel. A complex pattern of such channels is visible throughout the Pine Island Glacier shelf.

A Framework for Designing a Global Information Network for Multinational Humanitarian Assistance/Disaster Relief

Abstract: Large-scale Humanitarian Assistance/Disaster Relief (HA/DR) operations, particularly in developing countries, require the intervention and aid of various agencies from all over the world in a concerted and timely manner. As a result, HA/DR operations involve dynamic information exchange, planning, coordination and above all negotiation. Although a number of studies have reported the benefits of using information and communication technologies to support negotiation activities, it remains unclear how such technologies could be adapted to large-scale HA/DR operations. This paper examines negotiational issues involved in a multinational HA/DR environment and presents a framework that would help in developing a Global Information Network (GIN). The proposed framework can be used to assess and characterize individual disaster situations so that the GIN functional and design requirements can be accurately identified early. Future implications to GIN architecture are also discussed.

A Kolmogorov-Smirnov Test for Censored Samples

Abstract: Modifications of the two-sided one-sample Kolmogorov-Smirnov “goodness-of-fit” test, for use with censored and truncated samples, are suggested. Tables of the distributions of the modified statistics are given. Applications to life testing and reliability estimation problems are discussed.
