The seismic stratigraphy of the eastern Grand Banks continental margin is examined, and a five-fold division of the sedimentary sequence overlying basement is proposed. Oceanic basement of Cretaceous age underlies the eastern part of the study area; to the west, continental basement ranging in age from Late Precambrian to ?Jurassic underlies the Grand Banks. The sediment units, ranging in age from Early Cretaceous to Recent, have been dated by extrapolation of both commercial and DSDP drilling results from the Grand Banks and from the formerly conjugate Iberian margin. Identification of oceanic magnetic anomalies in the Newfoundland Basin agrees with the proposed age of the two oldest, Early Cretaceous units.
The Natural Environment Research Council (NERC) is one of seven UK Research Councils. It delivers independent research, survey, training and knowledge transfer in the environmental sciences. All the UK Research Councils are public bodies falling under the Freedom of Information Act 2000 and the Environmental Information Regulations 2004. This open access legislation came into force on January 1, 2005 and since then the authors have built up substantial experience in managing NERC’s data and information under both the Act and the Regulations. This article aims to explain how to manage the, often blurred, boundary between these two pieces of legislation, and the overlap between data management and the legislation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
