RESEARCH INTERESTS
 
Biogeochemical impact of rapid climatic change in eastern tropical north Pacific.
 
Even though a single climatic cycle lasts 150,000 years,climate changes large enough to have extensive impact on our society occur in 
only a decade.
With the increasing concern about the effects of global warming on an interannual-scale, I am interested in :
 
a) the interaction between high frequency climate cycles and longer-term cycles.
b) phase relations between high and low latitude climate cycles.
 
Marine varved sediments from ocean cores can be used to reconstruct records over long periods of time,at a resolution that can be applied to
all timescales.
This would give us a more complete picture of the dynamics of the ETNP-which is  an integral part of the El Nino Southern Oscillation system.
The research could provide valuable predictive information abuot ENSO through reconstruction of past changes in thermohaline circulation,
productivity and upwelling.
 
The ultimate aim is to search for the ‘drivers’ of the entire global climate system which seem to respond to a common forcing mechanism.
Personally,the earth fascinates me to no end.Understanding it holds the key to the complete realisation of our position as part of the earth
system.It is important to address how we are constantly modifying the dynamics of this system and how future trends of variation are affected 
by this.
