Apologies for the late notice - if you're interested in this topic but can't attend, do let me know and I'll see if I can put you in contact with Dr. Hedley.

Greetings, Science Fans!
You are invited to our next SoNS (School of Natural Sciences) seminar for 2012 at 3.30pm on Friday 20th July. Visiting Fellow Dr John Hedley from the UK will discuss a state-of-the-art 3D computer model for shallow water environments.

These are not "dumbed down" talks but real research presentations so content may be quite technical at times; nevertheless all interested members of the public are welcome to join us for the seminar plus drinks and nibbles afterwards, where you can chat with the researchers in person.
Places are strictly limited so RSVPs are essential.  To reserve your place, receive parking and venue details or to request further information, e-mail n.bordas at ecu.edu.au<mailto:n.bordas at ecu.edu.au> or leave a message on (08) 6304 5116.
If you'd like the maximum notice of upcoming seminars, reply to this e-mail asking to be put in contact with the series convenor.
In science,

SoNS Seminar Series, Friday July 20: Photobiology and remote sensing of shallow water ecosystems: results from recent advances in computational optics
Dr Dr John Hedley
ARGANS Ltd., Tamar Science Park, Plymouth, UK
Abstract
This seminar will present techniques and results from the application of a state-of-the art 3-dimensional radiative transfer model for shallow water environments. The model utilises the computer's Graphics Processing Unit (GPU) to construct a full 3D model of the light distribution in benthic canopies. The model has been applied to questions such as: does bright sand surrounding corals increase the chance of bleaching? And what is the minimum quantum requirement for growth of seagrass canopies?  The seminar will include results on the Western Australian seagrass Amphibolis griffithii arising from an ECU Industry Collaboration between Dr. Hedley and Kathryn McMahon of ECU and partners at Oceanica Consulting Pty Ltd. and Curtin University. Potential applications in remote sensing of complex underwater structures such as coral reefs will also be highlighted.

Refreshments following.  All welcome!
