Scientific data services are increasing in usage and scope, and with these increases comes growing need for access to provenance information. Our goal is to design and implement an extensible provenance solution that is deployed at the science data ingest time. In this paper, we describe our work in the setting of a particular set of data services in the area of solar coronal physics. The paper...

Based on almost three years of experience in developing and deploying scientific data frameworks built using semantic technologies, we now have a production virtual observatory in operation, serving two broad communities: solar physics and terrestrial upper atmospheric physics. Within this application, a data framework provides online location, retrieval, and analysis services to a variety of h...

In this paper we summarize the main properties of the ENACS (the ESO Nearby Abell Cluster Survey), which was one of the ESO Keypro-grammes carried out in the first half of the 1990's, and we discuss some recent work on the properties of the galaxies in the rich clusters in the ENACS sample. We stress the importance of the ENACS sample as a local , volume-limited sample of rich ACO clusters, whi...

In the near future several new surveys will provide tens of Terabytes of catalogued data for the astronomy community. The archives for these projects are currently being designed. Soon there will be an enormous pressure from the whole astronomical community to integrate these separate archives into a seamlessly interoperating entity. The public access of such amounts of data, and the necessary ...

INTRODUCTION The use of hodograms in interpretation of AVO cross-plots is a relatively recent innovation (Keho, 2000). Often, when comparing models of attributes to the actual seismic attributes, we find that anomalous zones are much closer to the background trend than the model indicates. One reason for this concerns wavelet effects. The AVO hodogram takes wavelet effects into account and can ...

Astronomy is entering a new era as multiple, large area, digital sky surveys are in production. The resulting datasets are truly remarkable in their own right; however, a revolutionary step arises in the aggregation of complimentary multi-wavelength surveys (i.e. the cross-identification of a billion sources). Federating these different datasets, however, is an extremely challenging task. With ...

Online sharing of scientific information has accelerated the research activity in various domains of science. This fact inspires us to initiate a new kind of approach in the field of network research and review some projects pointing towards this direction. Building on the experiences of similar efforts in other domains of sciences we are building a prototype node for Network Measurement Virtua...

Haystack Observatory is a multidisciplinary research center located in Westford, MA, 40 miles northwest of the MIT campus. The observatory conducts astronomical studies using radio techniques, geodetic measurements using Very Long Baseline Interferometry (VLBI), and atmospheric observations using high-power incoherent scatter radar. An important component of Haystack’s mission is the education ...
