(editor), Reigel, Ruth (editor), Proceedings of the Ocean Drilling Program; volume 164; scientific results; gas hydrate sampling on the Blake Ridge and Carolina Rise; covering Leg 164 of the cruises of the drilling vessel JOIDES Resolution, Halifax, Nova Scotia, to Miami, Florida, sites 991-997, 31 October-19 December 1995164421-429Geotechnical properties of sediment from Ocean Drilling Program Leg 164 are presented as: (1) normalized shipboard strength ratios from the Cape Fear Diapir, the Blake Ridge Diapir, and the Blake Ridge; and (2) Atterberg limit, vane shear strength, pocket-penetrometer strength, and constant-rate-of-strain consolidation results from Hole 995A, located on the Blake Ridge. This study was conducted to understand the stress history in a region characterized by high sedimentation rates and the presence of gas hydrates. Collectively, the results indicate that sediment from the Blake Ridge exhibits significant underconsolidated behavior, except near the seafloor. At least 10 m of additional overburden was removed by erosion or mass wasting at Hole 993A on the Cape Fear Diapir, compared to nearby sites.completedStructural geologyAtlantic OceanAtterberg limitsBlake Ridge DiapirBlake-Bahama Outer RidgeCape Fear DiapirdiapirsLeg 164marine sedimentationmarine sedimentsNorth AtlanticOcean Drilling ProgramODP Site 993ODP Site 995sedimentationsedimentation ratessedimentsshear strengthsoil mechanicsstresstectonicsunconsolidated materialsurn:org.iodp:exp:164urnlargerWorkCitationcampaignurn:org.iodp:exp:164:site:993urnlargerWorkCitationstudyurn:org.iodp:exp:164urnlargerWorkCitationcampaignurn:org.iodp:exp:164:site:995urnlargerWorkCitationstudyurn:org.iodp:exp:164urnlargerWorkCitationcampaignEnglishgeoscientificInformation-75.5341-75.311831.481232.5746
