Over the past few decades, we have realized that the silica cycle is strongly intertwined with
other major biogeochemical cycles, like those of carbon and nitrogen, and as such is …

Twenty years ago, measurements on ice cores showed that the concentration of carbon
dioxide in the atmosphere was lower during ice ages than it is today. As yet, there is no …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Residual macronutrients in the surface Southern Ocean result from restricted biological
utilization, caused by low wintertime irradiance, cold temperatures, and insufficient …

Carbon dioxide is the most important greenhouse gas after water vapor in the atmosphere of
the earth. More than 98% of the carbon of the atmosphere-ocean system is stored in the …

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

The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

The terrestrial sediment record indicates that the Earth's climate varied drastically in the
Precambrian era (before 550 million years ago), ranging from surface temperatures similar …

Documented variations in the isotopic compositions of some chemical elements are
responsible for expanded uncertainties in the standard atomic weights published by the …

Considered esoteric only a few years ago, research into the stable isotope geochemistry of
transition metals is moving into the geoscience mainstream. Although initial attention …
