Alkenone and foraminifer abundance data from Miocene and Pliocene Atlantic Coastal Plain sediments Alkenone and foraminifer abundance data from Miocene and Pliocene Atlantic Coastal Plain sediments
Alkenone data were extracted from core and outcrop samples from the Miocene and Pliocene of the mid Atlantic Coastal Plain. The Uk'37 index is used to estimate temperature and total C37 is used to estimate productivity. Planktonic foraminifer abundance's are provided for two cores.
Planktic foraminifer census data for ODP Sites 907, 909 and 911 Planktic foraminifer census data for ODP Sites 907, 909 and 911
Average abundances of polar/subpolar planktic foraminiferal species n the North Atlantic for Nordic Sea ODP Sites 907 and 909 represent percentages when Nordic Sea water was warm enough to support foraminifera. N. atlantica relative abundances at very high northern latitudes (ODP Site 909) are lower than at subpolar latitudes because N. pachyderma (s) dominated these very cold waters...
PRISM late Pliocene (Piacenzian) alkenone - derived SST data PRISM late Pliocene (Piacenzian) alkenone - derived SST data
This dataset collects sea surface temperature data generated through alkenone analysis of late Pliocene sediments collected from cores and field localities by USGS PRISM project members. Alkenone analysis of sample material was performed by Timothy Herbert at Brown University.

What the cliffs near America’s earliest settlements tell us about climate change What the cliffs near America’s earliest settlements tell us about climate change
Climate change is a big problem for natural habitats, people, and the systems that support society, including roads, water supply, electrical grids, and phone and internet connections. It’s an important theme in politics, economics, and culture. Scientists make computer models to show what the climate might be like in the future, and it looks very different from what we are used to...

Pliocene Model Intercomparison Project Phase 3 (PlioMIP3) – Science plan and experimental design Pliocene Model Intercomparison Project Phase 3 (PlioMIP3) – Science plan and experimental design
The Pliocene Model Intercomparison Project (PlioMIP) was initiated in 2008. Over two phases PlioMIP has helped co-ordinate the experimental design and publication strategy of the community, which has included an increasing number of climate models and modelling groups from around the world. It has engaged with palaeoenvironmental scientists to foster new data synthesis supporting the...

Early Pliocene (Zanclean) stratigraphic framework for PRISM5/PlioMIP3 time slices Early Pliocene (Zanclean) stratigraphic framework for PRISM5/PlioMIP3 time slices
Global reconstructions of Pliocene climate provide important insights into how the climate system operates under elevated temperatures and atmospheric CO2 levels. These reconstructions have been used extensively in paleoclimate modeling experiments for comparison to simulated conditions, and as boundary conditions.Most previous work focused on the Late Pliocene interval known as the mid...

Assessing environmental change associated with early Eocene hyperthermals in the Atlantic Coastal Plain, USA Assessing environmental change associated with early Eocene hyperthermals in the Atlantic Coastal Plain, USA
Eocene transient global warming events (hyperthermals) can provide insight into a future warmer world. While much research has focused on the Paleocene–Eocene Thermal Maximum (PETM), hyperthermals of a smaller magnitude can be used to characterize climatic responses over different magnitudes of forcing. This study identifies two events, namely the Eocene Thermal Maximum 2 (ETM2 and H2)...

Planktic foraminifera Planktic foraminifera
Planktic foraminifera are single-celled marine organisms that secrete calcium carbonate tests. They live in the ocean's photic zone, and when they die, their tests, each about the size of a grain of sand, collect on the ocean floor. The geographic distribution of planktic foraminifera is mostly governed by the temperature and salinity of the ocean surface, and species assemblages are...

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