During the austral summer 1977–78 the Scott Polar Research Institute (SPRI) conducted a fifth season of airborne radio echo sounding in Antarctica as part of a joint project with the US National Science Foundation Division of Polar Programs (NSF-DPP) and the Technical University of Denmark (TUD). In addition, trials were undertaken of a magnetometer installation, developed and operated, under NSF contract, by the Applied Physics Laboratory (APL) of the Johns Hopkins University, USA.

During December 1978 the Scott Polar Research Institute (SPRI) undertook its sixth and final season of long-range airborne radio echo sounding (RES) and magnetometry in Antarctica in cooperation with the US National Science Foundation Division of Polar Programmes (NSF-DPP) and the Electromagnetics Institute of the Technical University of Denmark (TUD). The 1978–79 season (DF–79) was part of a long-term programme of glaciological and geophysical investigation of the Antarctic ice sheet (Drewry and Meldrum 1978a; 1978b). The broad aims have been to extend a 100-km grid network over Antarctica for a study of surface form, thickness, internal structure, rheology, thermodynamics, electrical properties, basal conditions and processes, and sub-ice geology.

Public research funding agencies today are required to address proactively interdisciplinary research. “The Challenge of Funding Interdisciplinary Research: A Look Inside Public Research Funding Agencies” looks specifically at two funding agencies—the US National Science Foundation (NSF) and the EU European Research Council (ERC)—and how these bodies promote interdisciplinarity, on the one hand, and how they claim to identify it, on the other. Inevitably, this gives the funding agencies some definition power over what interdisciplinary research actually is or should be. At the same time, there are organizational constraints that restrict the funding agencies’ capacity to fully embrace novel ways of interdisciplinary collaboration and investigation.

Government funding of e-collaboration research in both the US and EU seems to be growing. In the EU, a key initiative to promote governmental investment in e-collabo-ration research is the Collaboration@Work initiative. This initiative is one of the EU’s Information Society Technologies Directorate General’s main priorities. In the US, government investment in e-collaboration research is channeled through several gov-ernment branches and organizations, notably the National Science Foundation. There are key differences in the approaches used for government funding of e-collaboration research in the EU and US. Some of these differences are discussed here, as well as related implications.

This article describes a knowledge preservation and re-use tool designed to capture the knowledge of a specific individual at the US National Science Foundation, for later retrieval by successors after his retirement. The system is designed in a Q&A format, where it is sufficiently intelligent to ask for clarifying questions. The primary objective was to create a system that would result in acceptance of the system by the users. The domain of interest to be preserved and re-used was programmatic knowledge about the NSF Industry/University Collaborative Research Centers (I/UCRC) Program, and more specifically, the knowledge of its long-time director, Dr. Alex Schwarzkopf. The system is called AskAlex and it uses a trio of techniques to accomplish its objectives. Contextual graphs (CxG) are used as the basic knowledge representation structure. CxG’s are assisted by a search engine and an ontology of terms to help find the proper contextual graph that can best answer the question being asked. Evaluations with users and potential users generally confirm our selection and provided some guidance for improvements in the system.

AbstractSince the austral summer of 1994-95 the Alfred Wegener Institute has carried out airborne radio-echo sounding (RES) measurements in Antarctica with its newly designed RES system. Since 1995-96 an ongoing pre-site survey for an ice-coring drill site in Dronning Maud Land has been carried out as part of the European Project for Ice Goring in Antarctica. The survey covers an area of 948 000 km2, with >49 500 km of airborne RES obtained from >200 hours of flight operation flown during the period 1994-97. In this paper, first results of the airborne RES survey are graphically summarized as newly derived maps of the ice thickness and subglacial topography, as well as a three-dimensional view of surface and subglacial bed and outcrop topography, revealing a total ice volume of 1.48 x 106 km3.

The locations and details of 145 Antarctic subglacial lakes are presented. The inventory is based on a former catalogue of lake-type features, which has been subsequently reanalysed, and on the results from three additional datasets. The first is from Italian radio-echo sounding (RES) of the Dome C region of East Antarctica, from which 14 new lakes are identified. These data also show that, in a number of occasions, multiple lake-type reflectors thought previously to be individual lakes are in fact reflections from the same relatively large lake. This reduces the former total of lake-type reflectors by six, but also adds a significant level of information to these particular lakes. The second dataset is from a Russian survey of the Dome A and Dome F regions of East Antarctica, which provides evidence of 18 new lakes and extends the coverage of the inventory considerably. The third dataset comprises three airborne RES surveys undertaken by the US in East Antarctica over the last five years, from which forty three new lakes have been identified. Reference to information on Lake Vostok, from Italian and US surveys taken in the last few years, is now included.

AbstractThe Deep Ice Sheet Coring (DISC) drill developed by Ice Coring and Drilling Services under contract with the US National Science Foundation is an electromechanical ice-drill system designed to take 122mm ice cores to depths of 4000 m. The new drill system was field-tested near Summit camp in central Greenland during the spring/summer of 2006. Testing was conducted to verify the performance of the DISC drill system and its individual components and to determine the modifications required prior to the system’s planned deployment for coring at the WAIS Divide site in Antarctica in the following year. The experiments, results and the drill crew’s experiences with the DISC drill during testing are described and discussed.
