Mapping of small-scale biological processes in sediment

What is it about?

Chemical processes occur in sediments at a scale that cannot be effectively analysed by taking core samples and slicing into subunits. This work extends an effective method of sediment 2D mapping to include more elements.

Why is it important?

When we investigate biological and chemical processes, we can more robustly determine the nature of these processes if we have more information. By allowing more metals or nutrients to be measured simultaneously we can better interpret the environment. This work reports the development of a new technology that allows simultaneous measurement of sulfide, phosphorus, vanadium and arsenic in sediments.

Perspectives

This technique is time consuming and expensive in terms of the instruments needed for the analysis. However, simultaneous chemical data is an essential requirement for furthering our scientific knowledge. This technique has also been successfully further developed by an Austrian team for looking at chemical processes around plant roots.
