Disequilibria between the long-lived parents and short-lived particle-reactive daughters
have been extensively used over the past six decades as tracers and chronometers in …

Radionuclides can provide key information on the temporal dimension of environmental
processes, given their well-known rates of radioactive decay and production. Naturally …

Sorbents based on Fe (OH) 3 and aluminum oxide are widely used in oceanology for the
recovery of cosmogenic radionuclides 7Be, 32Si, 32P, and 33P from the seawater. It is also …

The sinking velocity (SV) of organic particles is a critical driver of carbon transport to the
deep sea. Accurate determination of marine particle SV and their influencing factors is …

Ocean eddies play a major role in lateral and vertical mixing processes of particulate
organic carbon (POC), as well as in the transport of heat, salinity, and biogeochemical …

Distributions of the natural radionuclide 210Po and its grandparent 210Pb along the GP15
Pacific Meridional Transect provide information on scavenging rates of reactive chemical …

Black carbon (BC) is believed to be refractory and thus affects the timescale of organic
carbon conversion into CO2 and the magnitude of the sink of CO2. However, the fate of BC …

In order to determine the atmospheric input of 210Pb and seawater-dissolvable Pb in the
East Sea (Japan Sea), we measured the concentrations of total 210Pb and dissolved Pb (< …

Abstract 210Bi (t1/2= 5.01 d) is theoretically a radionuclide for tracing the particle cycle over
a timescale of hours to days. However, it has been rarely investigated in marine …

This study presents a time-efficient method of analysing 210Pb, 210Bi, and 210Po in natural
waters. The optimum pH (1.00), temperature (95° C), and time (4.5 h) for simultaneous auto …
