Welcome to the Rhubarb talks website

The 'Rhubarb Talks' are a series of seminars by PhD students for PhD students at NOCS.

Upcoming seminars are posted below and cover a whole range of scientific exploits. Talks are held every other Monday afternoon at 4.30pm in the postgrad lounge (node 086) and are accompanied by nibbles and refreshments.

For more info or to volunteer for a talk, please contact The Rhubarb Team: Liz (E.Sargent@noc.soton.ac.uk),
Rosanna (R.Greenop@noc.soton.ac.uk), Maike (mjsp106@soton.ac.uk) or Sara (Sara.Cregeen@noc.soton.ac.uk)

December 2011

On MONDAY 5TH DECEMBER there will be an exciting opportunity to hear and comment on Sara, Craig and Maike's talks for Contemporary Topics.

We would all really like to hear as much of your constructive feedback as you can give, so we can get our talks all polished up!

The titles are;
Craig: "The role of topography in ocean circulation"
Maike: "Ocean model fidelity and resolution"
Sara: "Microbial control of the biogeochemical cycling of methane: can
bugs control the climate?"

MONDAY 12TH OF DECEMBER Ben Timmermans will present a public talk recently given at the Art House Café....

Nuclear nightmare or media madness: As we bring our planet to its knees, what role could nuclear power have in its future, in light of events at Fukushima and current concerns?

The talk will review various aspects of nuclear power in the context of current energy demand, and the potential threat of climate change and associated carbon emission reduction targets.

On Monday 7th of November at 4.30PM come along to see Colette Couves present:

Porosity and Permeability Development within Unconventional Igneous Reservoirs

Venue: The PG lounge


Volcanic rocks are becoming increasingly recognized as viable petroleum reservoirs, with recent discoveries including the Miocene Minami-Nagaoka gas field in the Niigata basin, Japan, the Early Tertiary Padra oil field in India, and various Jurassic fields within the Austral basin of southern Argentina. Reservoir quality in these sequences is primarily controlled by porosity and permeability, which can be evaluated petrophysically through laboratory based measurements. Although porosities can commonly be relatively high in such rocks the permeabilities are often very low making it difficult to extract the hydrocarbons. The porosity/permeability characteristics can be modified by a number of secondary processes including fracturing due to tectonism and/or alteration due to metamorphism, meteoric or hydrothermal alteration.

X-Ray Computed Tomography is currently being evaluated as a potential tool to help more fully understand the controls on porosity-permeability development in a suite of variably altered Cretaceous volcanic rocks from South America. Basalts, andesites and rhyolites have been investigated to produce a qualitative visualization of the 3D pore structure, and a quantitative estimate of porosity. Integrating these high-resolution porosity maps with the results from more routine petrographical evaluation has permitted the evolution and nature of porosity development in these volcanic rocks to be better understood. Moreover, these porosity values can be compared with the results obtained from traditional petrophysical analysis so as to assess the potential industrial application of this new technique.

On MONDAY 28TH OF NOVEMBER come along to see Anna Sturrock present:

Finding Nemo: Using data storage tags to validate otolith chemistry as an indicator of plaice movements and connectivity
