Phosphorus (P) is essential for life, but most of the global surface ocean is P depleted, which
can limit marine productivity and affect ecosystem structure. Over recent decades, a wealth …

Global cooling in the Cenozoic, which led to the growth of large continental ice sheets in
both hemispheres, may have been caused by the uplift of the Tibetan plateau and the …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Microbial production of antibiotics is common, but our understanding of their roles in the
environment is limited. In this study, we explore long-standing observations that microbes …

The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …

▪ Abstract Phosphorus has a number of indispensable biochemical roles, but it does not
have a rapid global cycle akin to the circulations of C or N. Natural mobilization of the …

A sequential extraction method (SEDEX) has been developed to separately quantify five
sedimentary P reservoirs: loosely sorbed P; ferric iron‐bound P; authigenic carbonate …

A nonlinear inverse method is applied to nutrient data upon approximately 20 neutral
surfaces in each of the South Atlantic, Indian, and Pacific basins, between 400 and 4000 m …

This newly revised edition of Global Environment discusses the major elements of the
geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and …

Phosphorus (P) is a critical factor for food production, yet surface freshwaters and some
coastal waters are highly sensitive to eutrophication by excess P. A planetary boundary, or …
