Introduction

The geochemical ecology (Southampton University Marine Isotopes and Ecology SUMIE) group use natural chemical markers contained in the tissues of animals to track the flow of nutrients within food webs and the movement of animals across geochemical gradients.

Research

We focus on animals and ecosystems that are hard to observe directly, especially deep-sea ecosystems, pelagic sharks and seabirds of the open ocean.

We analyse many kinds of tissues, but particularly those that grow continually like scales and otoliths, as these tissues provide a record of age and behaviour throughout the life of the animal.

Our work involves field sampling, liaising with commercial and research fisheries and laboratory analysis. Overall our aim is to discover how and why marine ecosystems and animals function in order that they can be managed and conserved more effectively.
