The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

We report on the existence and nature of Holocene solar and climatic variations on
centennial to millennial timescales. We introduce a new solar activity proxy, based on nitrate …

Sustained observations provide critically needed data and understanding not only about
ocean warming and water cycle reorganization (eg, salinity changes), ocean eutrophication …

Bottom trawling grounds have been expanding to deeper areas of the oceans since the mid‐
XXth century, and mitigating strategies aimed to protect fish stocks, such as temporal …

Carbon preservation in marine sediments, supplemented by that in large lakes, is the
primary mechanism that moves carbon from the active surficial carbon cycle to the slower …

As part of the International Polar Year research program, we conducted a survey of surface
marine sediments from box cores along a section extending from the Bering Sea to Davis …

Identifying and dating first human colonization of new places is challenging, especially when
group sizes were small and material traces of their occupations were ephemeral. Generating …

Organic matter (OM) burial in marine sediments is a potentially important control on global
climate and the long-term redox state of the earth's surface. Still, we have only a limited …

Free-drifting sediment net traps were deployed 14 times at depths between 80 and 500 m for
1–3 days each during the late monsoon–intermonsoon transition in the central Arabian Sea …

Soil organic carbon (SOC) tracing can provide important information for effective and
accurate management of soil erosion. However, tracing erosion-induced SOC is still …
