The geochemistry of marine sediments is a major source of information about the past
environment. Of the many measurements that provide such information, those of the U …

Dust deposition in the Southern Ocean constitutes a critical modulator of past global climate
variability, but how it has varied temporally and geographically is underdetermined. Here …

The growth of siliceous phytoplankton, mainly diatoms, in the Southern Ocean influences the
preformed nutrient inventory in the ocean on a global scale. Silicic acid use by diatoms and …

There is increasing evidence indicating that syndepositional redistribution of sediment on
the seafloor by bottom currents is common and can significantly affect sediment mass …

The concentration and the major phase composition (particulate organic matter, CaCO 3,
opal, lithogenic matter, and iron and manganese oxyhydroxides) of marine particles is …

We have examined the relative affinity of Th, Pa and Be for sorption from seawater onto
particles of variable composition (opal, carbonate, lithogenic particles and organic carbon) …

Studies from the subtropical western and eastern Atlantic Ocean, using the 231Pa/230Th
ratio as a kinematic proxy for deep water circulation, provided compelling evidence for a …

Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐
resolution sediment fluxes during the late Pleistocene (last~ 500,000 years). As its …

The 230Th-normalization technique was applied to surface sediments and down-core
records from the Pacific sector of the Southern Ocean between 120° W and 170° W in order …

Abstract The equatorial Pacific Ocean is one of the major high-nutrient, low-chlorophyll
regions in the global ocean. In such regions, the consumption of the available macro …
