Bomb fall-out 236U as a global oceanic tracer using an annually resolved coral core

Anthropogenic 236U (t½=23.4 My) is an emerging isotopic ocean tracer with interesting oceanographic properties, but only with recent advances in accelerator mass spectrometry techniques is it now possible to detect the levels from global fall-out of nuclear weapons testing across the water column. To make full use of this tracer, an assessment of its input into the ocean over the past decades i...

Determination of irradiated reactor uranium in soil samples in Belarus using 236U as irradiated uranium tracer.

This work presents experimental results on the distribution of irradiated reactor uranium from fallout after the accident at Chernobyl Nuclear Power Plant (NPP) in comparison to natural uranium distribution in different soil types. Oxidation processes and vertical migration of irradiated uranium in soils typical of the 30 km relocation area around Chernobyl NPP were studied using 236U as the tr...

Annually resolved ice core records of tropical climate variability over the past ~1800 years.

Ice cores from low latitudes can provide a wealth of unique information about past climate in the tropics, but they are difficult to recover and few exist. Here, we report annually resolved ice core records from the Quelccaya ice cap (5670 meters above sea level) in Peru that extend back ~1800 years and provide a high-resolution record of climate variability there. Oxygen isotopic ratios (δ(18)...

Global budgets of oceanic and atmospheric methyl iodide : development of methyl iodide as a tracer for marine convectionin atmospheric models

Methyl iodide (CH 3 I) is mainly emitted to the atmosphere from the oceans, and photolyzes with a lifetime of 4 days in the tropics. It is of interest in the atmosphere as a tracer of marine convection and a source of iodine radicals. We present a global model simulation of oceanic and atmospheric CH 3 I using a box model of the oceanic mixed layer coupled to a global three-dimensional model of...
