[HTML][HTML] An overview of seabed mining including the current state of development, environmental impacts, and knowledge gaps
Rising demand for minerals and metals, including for use in the technology sector, has led to
a resurgence of interest in exploration of mineral resources located on the seabed. Such …

230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐
resolution sediment fluxes during the late Pleistocene (last~ 500,000 years). As its …

Trace element (Mn, Zn, Ni, V) and authigenic uranium (aU) geochemistry reveal sedimentary redox history on the Juan de Fuca Ridge, North Pacific Ocean
Abstract Changes in meridional overturning circulation and water mass chemistry can be
recorded by oxygen concentrations in the deep ocean. Because the deep Pacific is the …

Efficacy of 230Th normalization in sediments from the Juan de Fuca Ridge, northeast Pacific Ocean
Abstract 230 Th normalization is an indispensable method for reconstructing sedimentation
rates and mass fluxes over time, but the validity of this approach has generated …

Hydrothermal deposition on the Juan de Fuca Ridge over multiple glacial–interglacial cycles
Hydrothermal systems play an important role in modern marine chemistry, but little is known
about how they may have varied on 100,000 year timescales. Here we present high …

Pelagic sedimentation rates in the North Pacific using Thorium-230 depth profiling
Evaluating the stratigraphy of the North Pacific is the first step towards understanding the
role of this region in climate variability in the past. This region has been notoriously difficult …

Paleoproductivity and Stratification Across the Subarctic Pacific Over Glacial‐Interglacial Cycles
Abstract In the Subarctic Pacific, variability in productivity on glacial‐interglacial timescales
is often attributed to changes in stratification and nutrient delivery to the surface, but the …
