Geochemistry and P and Fe fractionation in anoxic sediments
We investigated the phosphorus (P) and iron (Fe) fractionation in four cores with anoxic sediments, deposited during the mid-Cretaceous oceanic anoxic event 2 (~94 Ma) and the... -
Analysis of minerals from Arctic Ocean sediments
The Arctic Ocean System is a key player regarding the climatic changes of Earth. Its highly sensitive ice Cover, the exchange of surface and deep water masses with the global... -
Geochemical and palynological results of IODP Hole 302-M0004A from Lomonosov ...
Several episodes of abrupt and transient warming, each lasting between 50,000 and 200,000 years, punctuated the long-term warming during the Late Palaeocene and Early Eocene (58... -
Core correlation data and revised composite depth scale of Exp302 (ACEX) cores
Expedition 302 of the Integrated Ocean Drilling Program (IODP), also known as the Arctic Coring Expedition (ACEX), successfully penetrated a sequence of Cenozoic sediments... -
X-ray diffraction analysis of sediment cores from the ACEX expedition to the ...
This data report extents the X-ray diffraction (XRD) work reported in the Scientific Results Volume from ~ 200 samples to 1555 investigated bulk powder samples. The unique... -
Geochemistry and mineralogy of Eocene-Oligocene sediments of IODP Hole 302-M0...
In 2004, Integrated Ocean Drilling Program Expedition 302 (Arctic Coring Expedition, ACEX) to the Lomonosov Ridge drilled the first Central Arctic Ocean sediment record reaching... -
Neodymium and Strontium chemistry of Arctic Ocean sediments
The early oceanographic history of the Arctic Ocean is important in regulating, and responding to, climatic changes. However, constraints on its oceanographic history preceding... -
Radiogenic isotope record of Arctic Ocean circulation and weathering inputs o...
Lead (Pb), neodymium (Nd), and strontium (Sr) isotopic analyses were carried out on sediment leachates (reflecting the isotope composition of past seawater) and digests of the... -
Salinity of the Eocene Arctic Ocean from oxygen isotope analysis of fish bone...
Stable isotope analysis was performed on the structural carbonate of fish bone apatite from early and early middle Eocene samples (~55 to ~45 Ma) recently recovered from the... -
Drift distances, times and primary grain sources of the Arctic Ocean, Exp302 ...
Knowledge of the long-term history of the perennial ice is an important issue that has eluded study because the Cenozoic core material needed has been unavailable until the... -
Mineralogical composition of the upper 300m of Hole 302-M0002A
During the Arctic Coring Expedition (ACEX), a 428-m-thick sequence of Upper Cretaceous to Quaternary sediments was penetrated. The mineralogical composition of the upper 300 m... -
Age control and stratigraphy of a sediment profile from the Lomonosov Ridge, ...
The upper 200 m of the sediments recovered during IODP Leg 302, the Arctic Coring Expedition (ACEX), to the Lomonosov Ridge in the central Arctic Ocean consist almost... -
Paleogene record of elemental concentrations in sediments from the Arctic Oce...
We present a high-resolution X-ray fluorescence (XRF) core scanner record for the expanded middle Eocene section from Integrated Ocean Drilling Program (IODP) Expedition 302... -
Macerals in sediments
The study of particulate organic matter (OM) in Arctic Ocean sediments from the Late Cretaceous to the Eocene (IODP Expedition 302) has revealed detailed information about the... -
Detailed analysis of the organic carbon content in sediment cores M0002 and M...
During IODP Expedition 302 (Arctic Coring Expedition-ACEX), the first scientific drilling campaign in the permantly ice-covered central Arctic Ocean, a 430 m thick sequence of... -
Bulk sedimentology from Sites M0002 and M0004 of the ACEX (Exp302) expedition...
Except for a few discontinuous fragments of the Late Cretaceous/Early Cenozoic climate history and depositional environment, the paleoenvironmental evolution of the pre-Neogene... -
(Table 1) Late Pleistocene planktonic foraminifera of Hole 302-M0004C
Planktonic foraminifera populations were studied throughout the top 25 meters of the IODP ACEX 302 Hole 4C from the central Arctic Ocean at a resolution varying from 5cm (at the... -
