14. Oligocene to Recent Calcareous Nannoplankton from the Philippine Sea, Deep Sea Drilling Project Leg 59
During Leg 59 of the Deep Sea Drilling Project, five sites (447 to 451) were occupied and seven holes drilled between Okinawa and Guam in the Philippine Sea (Fig. 1). All holes except Hole 447 yielded common calcareous nannoplankton at certain intervals cored. Nannoplankton assemblages and their age assignments will be discussed for each site, and fossil lists for selected samples from Holes 44...
متن کامل8. Molecular and Isotopic Compositions of Hydrocarbons at Site 533, Deep Sea Drilling Project Leg 76
In an investigation of gas hydrates in deep ocean sediments, gas samples from Deep Sea Drilling Project Site 533 on the Blake Outer Ridge in the northwest Atlantic were obtained for molecular and isotopic analyses. Gas samples were collected from the first successful deployment of a pressure core barrel (PCB) in a hydrate region. The pressure decline curves from two of the four PCB retrievals a...
متن کامل17. Iron-rich Sediments Cored during Leg 8 of the Deep Sea Drilling Project
A sequence of amorphous iron r>xide-rich sediments, interbedded with iron-free calcareous nannoplankton oozes, occurs in the basal zones of Sites 74 and 75 of the Deep Sea Drilling Project, immediately overlying basalt. These sediments have affinities with iron and manganeserich sediments previously described from the crest of the East Pacific Rise. It is considered most likely that this sedime...
متن کاملRecovery of Benthic Megafauna from Anthropogenic Disturbance at a Hydrocarbon Drilling Well (380 m Depth in the Norwegian Sea)
Recovery from disturbance in deep water is poorly understood, but as anthropogenic impacts increase in deeper water it is important to quantify the process. Exploratory hydrocarbon drilling causes physical disturbance, smothering the seabed near the well. Video transects obtained by remotely operated vehicles were used to assess the change in invertebrate megafaunal density and diversity caused...
متن کامل13. Major-element Chemistry of Basaltic Glasses Recovered during Deep Sea Drilling Project Leg
Fourteen microprobe analyses of basaltic glasses from three drill sites plus two dredged samples from the seafloor at the mouth of the Gulf of California suggest that magmatic liquids that cooled to form the volcanic crust in the Gulf of California have been fractionated, whereas other, more primitive submarine basalts from the Mid-Oceanic Ridge (MOR) have not. The limited chemical diversity am...
