Stable isotope and Magnesium/Calcium ratios of 4 profiles from the equatorial...
This thesis examines the closure history of the Central American Seaway (CAS) and its effect on changes in ocean circulation and climate during the time interval from ~6 – 2.5... -
Th-normalized fluxes, mass accumulation rates and age models of ODP Sites 202...
Biogenic particle flux was reconstructed using 230-Thorium normalization at two sites on the southern Chile margin. ODP Site 1233 at 41°S, 838 m depth, is at the southern limit... -
Late Quateranry dinoflagellate cysts of ODP Site 202-1233
The late Quaternary organic-walled dinoflagellate cyst record of Site 1233 (41°S, offshore Chile) was studied with a ∼200 year resolution spanning the last 25,000 years. The... -
Planktic foraminiferal abundance and faunal-derived sea surface temperature o...
Glacial cooling (~1-5°C) in the eastern equatorial Pacific (EEP) cold tongue is often attributed to increased equatorial upwelling, stronger advection from the Peru-Chile... -
Coccolithophore taxa and PCA factor analysis of ODP Site 1233
We provide high-resolution sea surface temperature (SST) and paleoproductivity data focusing on Termination 1. We describe a new method for estimating SSTs based on multivariate... -
Volcaniclastic layers in ODP Site 202-1241
This study presents a record of dissolution from the eastern equatorial Pacific (EEP) that extends to 2.1 Ma, based on sediments from Ocean Drilling Program (ODP) Site 1241. A... -
Benthic foraminifera extinction groups population in Middle Miocene sediments
Fifty-eight species of elongate, cylindrical benthic foraminifera (here referred to as the Extinction Group) belonging to genera that became extinct during the mid-Pleistocene... -
Occurrence of Selenopemphix undulata sp. nov in late Quaternary sediments of ...
Detailed palynological studies in the northeast (NE) Pacific, Strait of Georgia (BC, Canada), southeast (SE) Pacific and northwest Pacific (Dongdo Bay, South Korea) resulted in... -
Radiolarian biostratigraphy in sediments of ODP Site 202-1237
Site 1237 is located on Nazca Ridge ~140 km off the coast of Peru and thus within the offshore region of the Peru-Chile Current. A total of 83 samples were used to provide an... -
Biostratigraphy of tropical and equatorial Pleistocene nannofossils for ODP L...
During Ocean Drilling Program (ODP) Leg 202, Pleistocene calcareous nannofossils were recovered from several sites situated between 16°S and 8°N latitude. These sites are under... -
Stable carbon and oxygen isotopes and Mg/Ca ratios of foraminifers from ODP S...
A combination of stable isotope records and Mg/Ca temperature estimates of four different planktonic foraminiferal species from Ocean Drilling Program Site 1241 allows... -
Element ratios and stable isotopes of foraminifers from ODP Site 202-1237
Downcore records of magnesium/calcium, strontium/calcium, manganese/calcium, and oxygen and carbon isotopes of planktonic and benthic foraminifers from Ocean Drilling Program... -
Sediment and pore water N and d15N concentrations of ODP Holes 202-1234A and ...
The isotopic composition of nitrogen in pore water ammonium and in sedimentary organic matter (Norg) was measured at Sites 1234 and 1235 in order to evaluate the impact of... -
Phosphorus components, trace metals and Ba excess of ODP Site 202-1237 sediments
We determined the sedimentary concentrations of phosphorus (P), barium (Ba), manganese (Mn), titanium (Ti), aluminum (Al), and uranium (U) for sediment samples from the... -
TOC, CaCO3, n-alkane and alkenone concentrations of ODP Sites 202-1237 and 20...
We generated preliminary downcore records of total organic carbon content, calcium carbonate, long-chain n-alkane concentration, total alkenone concentration, and alkenone-based... -
Age models and foraminifer isotopes of four ODP Leg 202 sites
We present benthic isotope stratigraphies for Sites 1236, 1237, 1239, and 1241 that span the late Miocene-Pliocene time interval from 6 to 2.4 Ma. Orbitally tuned timescales... -
Isotope and Mg/Ca measurements from Cores ME0005A-43JC and 202-1242 of tropic...
