    ChEss is a recently-funded Census of marine life programme aimed at improving our knowledge of the biogeography of deepwater chemosynthetically driven ecosystems by promoting an international field phase of discovery and exploration. The main objectives are to assess and explain the diversity, distribution and abundance of hydrothermal vent and cold seep species. With the global mid-ocean ridge system extending similar to65000 km, it is unlikely that its entire length would be examined in detail. The ChEss programme proposes to select a limited number of target areas chosen for the discovery of new vents and seeps. The intention is to identify the maximum scientific return that could be achieved from detailed investigation of the minimum number of sites at key locations. To narrow the field for exploration, a number of starting hypotheses and goals have been identified. A bio- and geo-referenced database for hydrothermal vent and cold seep species will be created. This database will be integrated with the Ocean Biogeographic Information System (OBIS). An international scientific committee will coordinate the programme, facilitate collaboration between participants, promote ship-time applications at national level and stimulate scientific innovation from a wider community.
