The epoch of the Anthropocene, a period during which human activity has been the
dominant influence on climate and the environment, has witnessed a decline in oxygen …

Volcanism is a dominant natural source of mercury (Hg) to the atmosphere, biosphere,
ocean and sediments. In recent years, sedimentary Hg contents have emerged as a tool to …

Phytoplankton productivity and export sequester climatically significant quantities of
atmospheric carbon dioxide as particulate organic carbon through a suite of processes …

Rapidly spreading industrialization since the 19th century has led to a drastic increase in
trace metal deposition in coastal sediments. Provided that these trace metals have remained …

Internal phosphorus (P) loading is a key water quality challenge for shallow lakes. Addition
of iron (Fe) salts has been used to enhance P retention in lake sediments. However, its …

The Bakken black shales represent a unique sedimentary system characterized by high total
organic carbon contents (TOC; Lower Bakken shale= 10.8 and Upper Bakken shale= 11.8 …

Iron speciation is one of the most widely applied proxies used to reconstruct oxygen levels
and redox conditions in past aqueous environments. The iron speciation proxy estimates …

Sedimentary molybdenum (Mo) and uranium (U) enrichments are widely used to reconstruct
changes in bottom water oxygen conditions in aquatic environments. Until now, most studies …

Coastal zones account for 75% of marine methane emissions, despite covering only 15% of
the ocean surface area. In these ecosystems, the tight balance between methane production …
