Well-preserved nannofossil and stable isotope records from the mid-Cretaceous
of ODP Leg 171B (western North Atlantic) indicate cyclical, productivity-based
variations in surface water characteristics, ...
A detailed reconstruction of West African monsoon hydrology over the
past 155,000 years suggests a close linkage to northern high-latitude
climate oscillations. Ba/Ca ratio and oxygen isotope composition ...
This data set consists of atmospheric methane (CH4) concentrations
from the 3,230 m ice core taken by the Greenland Ice-core Project
(GRIP) covering the period between 40,000 and 8,000 yBP. Methane ...
The molecular stratigraphy of BOFS core 31K and ODP Hole 658C has been studied
for C37 alkenone abundances over the past 80 ka at high resolution (~circa
200-500 years). The derived Uk37 sea surface ...

Juvenile shells (instars A-1, A-2) of Candona rawsoni (a benthic ostracode
species with broad salinity tolerance) ...
I. "Acal2" is calibration data for same period as stable isotope records and
includes (from L to R) : 1) the date (based on 8-month (May-Dec) growth year
and centered at mid-month); 2) mean monthly ...
Arctic Ocean Paleoproductivity Data
Data Tables from Wollenburg, Kuhnt, and Mackensen, 2000.
Table 2. Sediment core PS2138-1. Percentages of foraminifers >63?m. *Only
species with a relative abundance ...
AMS14C dating and grain-size analysis for Core DD2, located at the north of
the Yangtze River-derived mud off the Zhejiang-Fujian coasts in the inner
shelf of the East China Sea, provide us a high-resolution ...
A method is presented to reconstruct decadal variations of the North Atlantic
Oscillation (NAO). The spectral characteristics of the NAO on time scales of
decades and longer are of particular interest ...
Nannofossil assemblages and fine fraction stable isotopes
from 4 localities in the North Sea Basin:
Location: BGS Borehole, North Sea
Based on benthic foraminiferal d18O from ODP Site 1143, a 5-Myr astronomical
timescale for the West Pacific Plio Pleistocene was established using an
automatic orbital tuning method. The tuned Brunhes/Matuyama ...
To better understand North Pacific climate variability at
interannual to interdecadal scales, we have developed a new tool for
paleoenvironmental reconstruction. We show that growth rings in
Timing of the Last Glacial Maximum from observed sea-level minima.
Faunal assemblages and preservation status of sediments from Bonaparte Gulf,
Australia, were used to reconstruct global ice volume, ...
A rapid increase in greenhouse gas levels is thought to have fueled global
warming at the Paleocene-Eocene Thermal Maximum (PETM). Foraminiferal
magnesium/calcium ratios indicate that bottom waters ...
Counts of 19 foraminiferal and 13 radiolarian species present in Core MD 85668,
Somali Basin, NW Indian Ocean, Latitude 0?01'0 S, 46?02'3 E, 4020 mbsf. Sample
depth in cm below seafloor. Occurrences ...
Hiatus database - contains Hiatus duration, depth in mbsf, and paleo-water
depth from DSDP and ODP deep-sea holes. Compilation based on the subset of
DSDP/ODP holes collected in the 'Neptune' micropaleontological ...
New faunal and floral records from Ocean Drilling Project Hole 963A, resolved
at ~80-year spacing, provide evidence of suborbital scale climate variability
in the central Mediterranean Sea throughout ...
