Application of the Modern Analog Technique (MAT) of sea surface temperature estimation to middle Pliocene North Pacific planktonic foraminifer assemblages Application of the Modern Analog Technique (MAT) of sea surface temperature estimation to middle Pliocene North Pacific planktonic foraminifer assemblages
Seventy-two samples from Deep Sea Drilling Project Sites 445 and 463 and Ocean Drilling Program Site 769 from the northwest Pacific Ocean were compared to 499 modern core top Pacific Ocean samples using the squared chord distance dissimilarity measure. Many samples show high levels of dissimilarity that can be explained by pervasive dissolution and/or evolution changing the composition...

Paleontology and physical stratigraphy of the USGS-Pregnall No. 1 core (DOR-208), Dorchester County, South Carolina Paleontology and physical stratigraphy of the USGS-Pregnall No. 1 core (DOR-208), Dorchester County, South Carolina
Pregnall No. 1, a 346-ft-deep corehole in northern Dorchester County, South Carolina, recovered sediments of late Paleocene, middle and late Eocene, and late Oligocene age. The core bottomed in the Chicora Member of the Williamsburg Formation (Black Mingo Group) of late Paleocene age (calcareous nannofossil Zones NP 7/8 (?) and NP 9). The Chicora (346 to 258 ft depth) consists of two...

Late Paleocene and early Eocene calcareous nannofossils from three boreholes in an onshore-offshore transect from New Jersey to the Atlantic Continental Rise Late Paleocene and early Eocene calcareous nannofossils from three boreholes in an onshore-offshore transect from New Jersey to the Atlantic Continental Rise
Closely spaced, upper Paleocene and lower Eocene samples from three boreholes near Clayton, NJ, at Island Beach, NJ, and at Site 605 on the Atlantic Ocean continental rise were examined for their calcareous nannofossil content. This study documents calcareous nannofossil occurrences in Zones NP9 and NP10 and identifies biostratigraphically useful species, presents unexpected upbasin...

Reinterpretation of the peninsular Florida Oligocene: An integrated stratigraphic approach Reinterpretation of the peninsular Florida Oligocene: An integrated stratigraphic approach
A very thick (> 300 m) nearly continuous Oligocene section exists in southern peninsular Florida, as revealed by lithostratigraphic, biostratigraphic (mollusks and dinocysts), chronostratigraphic (Sr isotopes) and petrographic analyses of twelve cores and two quarries. The Oligocene deposits in the subsurface of southern Florida are the thickest documented in the southeastern U.S., and...

Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change
Boreholes from Island Beach, Allaire, Atlantic City, and Mays Landing, NJ provide an excellent chronology of lower to middle Eocene passive margin sequences and allow analysis of long-term sea-level changes and sedimentation patterns. These New Jersey sequences are tied directly to the geomagnetic polarity time scale through magnetostratigraphy. Integrated stratigraphy (including

The Blake Nose Cretaceous-Paleogene (Florida Atlantic margin, ODP Leg 171 B): An exemplar record of the Maastrichtian-Danian transition The Blake Nose Cretaceous-Paleogene (Florida Atlantic margin, ODP Leg 171 B): An exemplar record of the Maastrichtian-Danian transition
During ODP Leg 171B, devoted to the analysis of the Blake Plateau margin in front of Florida, 16 holes have been drilled in 5 distinct sites. The sites have documented a sedimentary succession ranging in age from Aptian to Eocene. Emphasis has been put on critical periods, comprising the Paleocene-Eocene transition, the Cretaceous-Tertiary boundary which has been cored in excellent...

Upper Eocene sequence stratigraphy and the Absecon Inlet Formation, New Jersey Coastal Plain Upper Eocene sequence stratigraphy and the Absecon Inlet Formation, New Jersey Coastal Plain
We evaluate the age, benthic biofacies, and sequence stratigraphy of thick and well-recovered upper Eocene sediments from the New Jersey Coastal Plain. These strata are herein defined as a lithostratigraphic unit and named the Absecon Inlet Formation. The formation is divided into upper and lower portions. At its type locality in the Atlantic City borehole, the lower portion of the...

Middle Pliocene sea surface temperatures: A global reconstruction Middle Pliocene sea surface temperatures: A global reconstruction
Identification and analyses of Pliocene marine microfossils from 64 globally distributed stratigraphic sequences have been used to produce a middle Pliocene sea surface temperature reconstruction of the Earth. This reconstruction shows little or no change from current conditions in low latitude regions and significant warming of the ocean surface at mid and higher latitudes of both...

Southeast Atlantic marine and terrestrial response to middle Pliocene climate change Southeast Atlantic marine and terrestrial response to middle Pliocene climate change
Analysis of planktic foraminifers and pollen from Deep Sea Drilling Project Site 532 located on the continental margin of southwest Africa provides information on the link between Pliocene paleoceanographic conditions and paleoenvironments of southwest Africa. Increased upwelling at Site 532 correlates with southward migration of onshore vegetation regions. Both terrestrial and marine...
