Ocean uptake of Carbon Dioxide (CO2): Are the Oceans Acidifying?

Dr Steve Widdicombe

Plymouth Marine Laboratories, UK



Geological Storage of Carbon Dioxide (CO2): How long can we keep it out of
the atmosphere?

Dr John Bradshaw

Geoscience Australia/ CO2CRC



Thursday 7 July 2005

5.30 - 6.40 pm, The Shine Dome

Gordon Street, Acton, Canberra



Dr Steve Widdicombe is a marine ecologist and biodiversity expert. He
contributed to the European Union funded "Network of Excellence"
Co-coordinating Committee, on the geological storage of CO2, providing
expertise on the potential environmental consequences of CO2 leakage. He 
also
regularly provides advice on this issue to UK government departments and
environmental NGOs. Steve is currently the principle investigator on a 
number
of nationally funded projects assessing the impact of pH change on marine
benthic sediment systems.



SW Abstract: With world primary energy demand projected to rise at an 
average
of 1.7% annually over the next 30 years this means an increase in the 
release
of carbon dioxide. Of all the predicted impacts attributed to this 
inevitable
rise in atmospheric CO2 concentration (and the associated rise in
temperature), one of the most pressing is the acidification of surface 
waters
through the absorption of the atmospheric CO2 and its reaction with seawater
to form carbonic acid. It is predicted that this process may lead to a
surface ocean pH reduction of 0.7 units by the end of the century. It is
clear therefore that the growing emissions of CO2 from anthropogenic
processes could pose a distinct threat to the global environment. However
quantifying the consequences of CO2 release is problematic as many physical
and biogeochemical processes combine to create a complex set of 
interactions.
This presentation will introduce the process of ocean acidification,
highlight some of the key environmental concerns and discuss some of the
mitigation strategies that have been suggested.



Dr John Bradshaw has worked as a consultant, in industry and government over
the last 24 years. He has managed several large industry sponsored research
programmes examining the petroleum potential of Australia and PNG, and has
published over 90 papers and reports. Since 1999 he has dedicated all of his
time to CO2 Storage of CO2, working with the GEODISC project and the
Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC). He is
currently a Principal Research Scientist at Geoscience Australia, is a Lead
Author on the Special Report by the Intergovernmental Panel on Climate 
Change
on Carbon Capture and Storage, and is part of the Australian technical
delegation on the international Carbon Sequestration Leadership Forum. He is
a member of PESA, AAPG, DEG and GSA.
