Event details

An oceanographic cruise is very different from a trip on the Queen Mary or Aurora.

Leigh Marsh and Laura Hepburn conclude their two-part analysis of what life on the ocean wave is really like.

The discovery of chemosynthetic environments in 1977 is arguably one of the great multidisciplinary oceanographic achievements of 20th century. However, thirty-three years later, 90% percent of the oceanic ridge system remains unexplored. With the global mid-ocean ridge system extending more than 65,000 km, it is unlikely that its entire length could be examined in detail.

With this in mind, the ChEsS (Chemosythetic Ecosystem Science) programme proposed and selected a limited number of target areas chosen for the discovery of new vents and seeps.

One of these key locations is the Southern Ocean, with exploration fronted by the ChEsSo (ChEss in the Southern Ocean) Programme. Using new footage from their most recent expedition to the East Scotia Ridge and Bransfield Strait, this talk will tell the story of the search for new hydrothermal vent fields, and what happens when it all goes wrong!

Further information

This talk is open to the public and admission is free.

You should arrive at the National Oceanography Centre Southampton at 7.15pm to be met in Reception.

Arrangements for wheelchairs must be made in advance. Unless it is possible to descend via the stairs in an emergency, access to upper floors cannot be permitted as lifts are automatically immobilised when the fire alarm is activated.

Speaker information

Leigh Marsh,Ocean and Earth Science, University of Southampton. Leigh graduated with a Masters of Oceanography from the University of Southampton in 2005. Since graduating, Leigh has worked for the Environment Agency, Natural England and more recently as a commercial marine ecologist for a Southampton based survey company. In October 2009, she returned to the NOCS to start a PhD investigating the controls on faunal microdistribution and reproductive development in deep-sea chemosynthetic environments in the Antarctic.

Laura Hepburn,Ocean and Earth Science, University of Southampton. Laura is also a PhD student at NOCS. After graduating as a Master of Oceanography from the University of Southampton in 2008, she began working within the Geochemistry Group of NOCS. Eager to continue research work she successfully applied for a PhD project investigating geochemical controls on microbial processes within chemosynthetic habitats of the Southern Ocean
