▪ Abstract Vertebrate fossils and continental sediments provide a rich record of variations in
the isotopic composition of surface environments. To interpret these records, a greater …

Fifteen years after the discovery of major glacial/interglacial cycles in the CO2 concentration
of the atmosphere, it seems that all of the simple mechanisms for lowering pCO2 have been …

Ocean Biogeochemical Dynamics provides a broad theoretical framework upon which
graduate students and upper-level undergraduates can formulate an understanding of the …

The carbon isotope ratio (δ13C) of plant material is commonly used to reconstruct the
relative distribution of C3 and C4 plants in ancient ecosystems. However, such estimates …

Using 95 epibenthic δ13C records, eight time slices were reconstructed to trace the
distribution of east Atlantic deepwater and intermediate water masses over the last 30,000 …

Ice-core measurements indicate that atmospheric CO2 concentrations during glacial periods
were consistently about 80 parts per million lower than during interglacial periods. Previous …

There is approximately 50 times more inorganic carbon in the global ocean than in the
atmosphere. On time scales of decades to millions of years, the interaction between these …

Atmospheric carbon dioxide is the raw material for the biosphere. Therefore, changes in the
carbon isotopic composition of the atmosphere will influence the terrestrial δ13C signals we …

We distinguish three different stages in the evolution of the Tithonian (Late Jurassic) to
Aptian (Early Cretaceous) northern Tethyan carbonate platform:(1) carbonate production in …

Measurements of water levels in the main channels of rivers, upland tributaries and
floodplain lakes are necessary for understanding flooding hazards, methane production …
