Piacenzian (Pliocene) foraminiferal faunal census data from Sites DSDP 594, ODP 642, ODP 846, ODP 882, ODP 982, ODP 1073, ODP 1088, and ODP 1146

Planktic foraminiferal species distributions in the modern ocean track environmental features like latitudinal temperature gradients. Species shift their distributions as the marine environment changes, providing an analog for past behavior. Stationarity of species’ ecological tolerances is a first-order assumption of all paleoenvironmental reconstructions based upon modern analog...

Zanclean Age Benthic Foraminiferal Census and Sedimentologic Data from the Yorktown Formation, Spring Grove, Va

Data consist of census counts of Pliocene benthic foraminifera from the Yorktown Formation at Pipsico Boy Scout Camp, Spring Grove, Virginia. Data consist of grain-size distribution by weight in grams of samples collected from the Yorktown Formation exposed in outcrop along the James River at Pipsico Boy Scout Camp, Spring Grove, Virginia. In total, counts of individuals from 15 samples...

Microfossil biostratigraphy and paleoenvironments of Cretaceous and Pliocene sediments along Greens Mill Run, North Carolina, USA

Cretaceous sediments are disconformably overlain by Pliocene sediments along the banks of Greens Mill Run, Greenville, North Carolina, located in the central coastal plain. The Cretaceous sediments, composed of glauconitic sand and clay, have previously been informally considered part of the Maastrichtian Peedee Formation. The Pliocene sediments are assigned to the Yorktown Formation and...

Insights into glendonite formation from the upper Oligocene Sagavanirktok Formation, North Slope, Alaska

The type locality for the upper Oligocene Nuwok Member of the Sagavanirktok Formation (Carter Creek, North Slope, Alaska, USA) contains abundant occurrence of glendonite, a pseudomorph after the calcium carbonate mineral ikaite, which typically forms in the shallow subsurface of cold marine sediments. The region during the time of Nuwok Member deposition was located at a high latitude...

The relative stability of planktic foraminifer thermal preferences over the past 3 million years

Stationarity of species’ ecological tolerances is a first-order assumption of paleoenvironmental reconstruction based upon analog methods. To test this and other assumptions used in quantitative analysis of foraminiferal faunas for paleoceanographic reconstruction, we analyzed paired alkenone unsaturation ratio (UK′37) 37′) sea surface temperature (SST) estimates and relative abundances...

Mid-piacenzian of the north Atlantic Ocean

The Piacenzian Age (Pliocene) represents a past climate interval within which frequency and magnitude of environmental changes during a period of past global warmth can be analyzed, climate models can be tested, and results can be placed in a context to better prepare for future change. Here we focus on the North Atlantic region, incorporating new and existing faunal assemblage and...

Environmental and geomorphological changes on the eastern North American Continental Shelf across the Paleocene-Eocene Boundary

Foraminiferal evidence from two sites in southern Maryland, eastern United States, reveals a series of rapid ecological changes on the continental shelf during the onset of the Paleocene-Eocene Thermal Maximum (PETM). Benthic and planktic foraminifer assemblages from the South Dover Bridge (SDB) and Mattawoman Creek-Billingsley Road (MCBR) cores in the central Salisbury Embayment record...

Paleo Research: Integrating Systems and Models (PRISM5)

PRISM5 addresses how the world, and particularly the US east coast, is affected by change. We study past warm periods from the Pliocene, Middle Miocene and early Eocene because these periods provide a suite of natural experiments in which marine ecosystems responded to rapidly changing temperature, sea-level and atmospheric CO2 for comparison to modern and future projections. We study how both...
