A revised calendar age for the last reconnection of the Black Sea to the global ocean
Abstract During the last decade, a debate arose regarding the timing and pattern of the last reconnection of the Black Sea “Lake” with the global ocean. On a geochemical basis, the radiocarbon age ofExpand

Hf and Nd isotopes in marine sediments: Constraints on global silicate weathering
The combined use of Lu–Hf and Sm–Nd isotope systems potentially offers a unique perspective for investigating continental erosion, but little is known about whether, and to what extent, the Hf–NdExpand

Millennial-scale fluctuations of the European Ice Sheet at the end of the last glacial, and their potential impact on global climate
Abstract Reconstructing Northern Hemisphere ice-sheet oscillations and meltwater routing to the ocean is important to better understand the mechanisms behind abrupt climate changes. To date, researchExpand

Black Sea “Lake” reservoir age evolution since the Last Glacial — Hydrologic and climatic implications
Abstract Chronologies of sediments that document the last glacial history of the Black Sea “Lake” are hampered by issues relating to reservoir age. Regulated by basin hydrology, reservoir agesExpand

Freshening of the Marmara Sea prior to its post-glacial reconnection to the Mediterranean Sea
During the last glaciation the Marmara Sea was isolated from the Mediterranean Sea because global sea level was below the depth of the Dardanelles sill. Prior to the postglacial reconnection to theExpand

Glacial hydrologic conditions in the Black Sea reconstructed using geochemical pore water profiles
Abstract Chloride and δ 18 O compositions of interstitial water extracted from a long sediment core retrieved from the NW coast of the Black Sea allowed us to constrain the main hydrologic changes ofExpand

Abrupt drainage cycles of the Fennoscandian Ice Sheet
Continental ice sheets are a key component of the Earth’s climate system, but their internal dynamics need to be further studied. Since the last deglaciation, the northern Eurasian Fennoscandian IceExpand

Assessing the blank carbon contribution, isotope mass balance, and kinetic isotope fractionation of the Ramped Pyrolysis/Oxidation instrument at NOSAMS
We estimate the blank carbon mass over the course of a typical Ramped PyrOx (RPO) analysis (150–1000°C; 5°C×min –1 ) to be (3.7±0.6) μg C with an Fm value of 0.555±0.042 and a δ 13 C value ofExpand

A Note on Reporting of Reservoir 14C Disequilibria and Age Offsets
Reservoir age offsets are widely used to correct marine and speleothem radiocarbon age measurements for various calibration purposes. They also serve as a powerful tracer for carbon cycle dynamics.Expand

Using Stable Carbon Isotopes to Quantify Radiocarbon Reservoir Age Offsets in the Coastal Black Sea
Constraining radiocarbon ( 14 C) reservoir age offsets is critical to deriving accurate calendar-age chronologies from 14 C dating of materials which did not draw carbon directly from the atmosphere.Expand
