The biogeochemical cycles of trace elements and their isotopes (TEIs) constitute an active
area of oceanographic research due to their role as essential nutrients for marine organisms …

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

Hydrothermal vents serve as a primary interface between the cold deep ocean and the warm
oceanic crust. While early research showed that seawater-rock interactions add to or remove …

Ferromanganese crusts collected at selected locations along the~ 7000 km long stretch of
Carlsberg, Central Indian and Southwest Indian ridges are studied for bulk geochemical …

A common technique for determining the mass accumulation rates of marine sediments is
through measurements of constant flux proxies. These proxies, like unsupported 230 Th and …

Abstract Thorium-230 (230 Th) is a fundamental tool for estimating sediment fluxes in the
open ocean. Because 230 Th is rapidly scavenged by particles falling through the water …

The naturally-occurring radionuclides protactinium-231 (231 Pa) and thorium-230 (230 Th)
are produced at approximately uniform rates in the ocean and thought to be removed from …

With the continuous deepening of research on seafloor hydrothermal observations, the
demand for a sustainable power supply of observation equipment is increasingly urgent. A …

Abstract The Southern Ocean hosts complex connections between ocean physics,
chemistry, and biology. Changes in these connections are hypothesized to be responsible …

Metal-enriched minerals have been widely observed near hydrothermal vent fields.
However, the dynamics of particulate metals influenced by hydrothermal activities is poorly …
