Ralph Lewis the original Connecticut project chief; and Mary DiGiacomo-Cohen and Valerie Paskevich for completing the Arc processing and creation of the GIS data layer.
The purpose is to disseminate a digital version of a regional map showing the distribution of vibracores collected during 1988 in Long Island Sound aboard the Atlantic Twin as part of a cooperative between New England coastal states and the Minerals Management Service. These cores, which were used to verify interpretations of high-resolution seismic-reflection profiles, can be used to provide useful information about the framework geology in this region.
Are there legal restrictions on access or use of the data?Access_Constraints: None
Use_Constraints:The U.S. Geological Survey, Connecticut DEP, and the U.S. Minerals ManagementService must be referenced as the originators of the dataset in any future products or research derived from these data. Although this derived data set and its lineage dataset have been used by the USGS, no warranty, expressed or implied, is made by the USGS as to the accuracy of the data and/or related materials. The act of distribution shall not constitute any such warranty, and no responsibility is assumed by the USGS in the use of these data or related materials.
Unless otherwise stated, all data, metadata and related materials are considered to satisfy the quality standards relative to the purpose for which the data were collected. Although these data and associated metadata have been reviewed for accuracy and completeness and approved for release by the U.S. Geological Survey (USGS), no warranty expressed or implied is made regarding the display or utility of the data for other purposes, nor on all computer systems, nor shall the act of distribution constitute any such warranty.
