Professor Dave Craw
Director of Environmental Science
Professor Dave Craw is the Chairperson of the Environmental
Science Board. He is based in the Department of Geology where he lectures
on geology and geochemistry of groundwater, mineral deposits, coal
and oil. His principal interests are in relationships between water
in the Earth's crust and active geological processses. He runs a PGSF-funded
programme on environmental effects of mining which is currently focusing
on heavy metal mobility in historical mine sites and shallow groundwater.
Current specific projects are focussed on arsenic mobilisation and
attenuation around gold and coal mines in Otago, and mercury mobility
in Otago and Northland. On a larger scale, he has research interests
in mountain-building processes and their impact on groundwater movement.
This research is conducted primarily in the actively rising Southern
Alps of New Zealand and in the Himalaya. The significance of these
processes to gold mobility and deposition is currently funded by a
separate PGSF contract.
