Sediment was classified using the Wentworth (1929) grain-size scale and the Shepard (1954) scheme of sediment classification. Certain grain-size categories are combined because of the paucity of some sediment textures; blank parts of the maps indicate areas where data are insufficient to infer sediment type. Bathymetry is used as a guide in placing some of the contacts between different sediment types. However, because the true boundaries between sediment types are probably highly irregular or gradational, because the extreme textural variability that characterizes some areas does not appear at this scale, and because the accuracy of the navigational systems used during the earlier studies is limited, all contacts should be considered to be inferred. Purpose: The purpose of the CONMAP sediment layer is to show the sediment grain size distributions. The maps depicted in this series are old and do not accurately depict small-scale sediment distributions. This data layer is supplied primarily as a gross overview and to show general textural trends Supplemental_Information: Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1982 Ending_Date: 1999 Currentness_Reference: Status: Progress: Complete Maintenance_and_Update_Frequency: Continually Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -82.0428 East_Bounding_Coordinate: -64.0000 North_Bounding_Coordinate: 45.2168 South_Bounding_Coordinate: 24.0118 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: surficial sediment Theme_Keyword: polygons Theme_Keyword: sediment type Theme_Keyword: grain size Theme_Keyword: sediemnt textural trends Theme_Keyword: sediment distribution Place: Place_Keyword_Thesaurus: None Place_Keyword: Eastern U.S. Place_Keyword: Exclusive Economic Zone Place_Keyword: coastal ocean Place_Keyword: Georges Bank Place_Keyword: Gulf of Maine Place_Keyword: Baltimore Canyon Trough Place_Keyword: Carolina Trough Place_Keyword: Blake Plateau Access_Constraints: none Use_Constraints: Not legally binding Point_of_Contact: Contact_Information: Contact_Organization_Primary: Contact_Organization: USGS Woods Hole Field Center Contact_Person: Larry Poppe Contact_Position: Geologist Contact_Address: Address_Type: mailing and physical address Address: 384 Woods Hole Road City: Woods Hole State_or_Province: MA Postal_Code: 02543-1598 Country: USA Contact_Voice_Telephone: 508-457-2314 Contact_Facsimile_Telephone: 508-457-2310 Contact_Electronic_Mail_Address: lpoppe@usgs.gov Hours_of_Service: Monday-Friday, 8am-5pm, Eastern Standard Time Native_Data_Set_Environment: ArcView version 3.1 shapefile format h:\texture2\mapping\conmap\conmapsg.shp Top
