Oxygen minimum zones (OMZs) harbor unique microbial communities that rely on
alternative electron acceptors for respiration. Conditions therein enable an almost complete …

Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean
could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply …

Inspired by the brain's structure, we have developed an efficient, scalable, and flexible non–
von Neumann architecture that leverages contemporary silicon technology. To demonstrate …

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 …

Denitrification, the reduction of the nitrogen (N) oxides, nitrate (NO3−) and nitrite (NO2−), to
the gases nitric oxide (NO), nitrous oxide (N2O), and dinitrogen (N2), is important to primary …

The carbon and nitrogen isotope composition of organic matter has been widely used to
trace biogeochemical processes in marine and lacustrine environments. In order to …

The fate of carbon (C) in organisms, food webs, and ecosystems is to a major extent
regulated by mass‐balance principles and the availability of other key nutrient elements. In …

The marine nitrogen cycle is perhaps the most complex and therefore the most fascinating
among all biogeochemical cycles in the sea. As a limiting element for biological productivity …

Current chemostratigraphical studies of the Jurassic System primarily involve the use of one
sedimentary component (marine organic carbon), one divalent transition metal substituted in …

The present paper is the result of a workshop sponsored by the DFG Research
Center/Cluster of Excellence MARUM" The Ocean in the Earth System", the International …
