Biography
Emma is a Master's candidate at in the Marine Mammal Unit. Her undergraduate
degree in Environmental Biology focused mostly on the study of ecological
issues, and her undergraduate thesis involved using paleolimnology (the
study of fossils in lake sediment) to assess the effects of past forestry
activity on watersheds in the British Columbian interior. After a year
living abroad and working for the Chilean Department of Environment,
she joined the Faculty of Graduate Studies at the University of British
Columbia.
Emma's Master's project, under the supervision of Dr. Andrew Trites,
consists of building an ecosystem model of the Southern Ocean. Using
the software package Ecopath with Ecosim, she's concentrating on the
South Atlantic Sector of the Southern Ocean, which includes the Island
of South Georgia and the South Orkney Islands. This area supports large
pinniped populations (e.g. Antarctic fur seals) and is an important
feeding ground for large whales. One of the issues being explored deals
with the potential effects of an expanded krill fishery in the area
on marine mammal populations. Another focus of the research is the investigation
of hypotheses for the apparent lack of recovery of many whale species
in spite of the moratorium on commercial whaling in the Southern Ocean.
This research has been enriched by collaborations with colleagues from
Canada, the US, Chile, and the UK.
