Spatial variability in residence time of Beryllium in the Indian Ocean.

Residence time of an element in the ocean is a consequence of its chemical behaviour and the various biogeochemical processes governing its distribution, sources, and sinks. Precise estimation of the residence time of beryllium(Be) is necessary for its application as a tracer for understanding present and paleo-environmental processes. We utilise cosmogenic Be and terrestrially derived Be measurements from surface sediments to estimate the residence time of Be in the Indian Ocean.
