Research Interest 1
Primary research questions include:
What are the primary factors controlling the quality and quantity of organic matter reaching the seafloor?
Can we detect climatic variation in the quantity/quality of organic matter reaching the seafloor?
How does variation in the supply of organic matter to the seafloor and long-term changes in benthic community structure at the seafloor impact benthic trophodynamics?
Do benthic fauna feed/assimilate on organic matter selectively? What are the impact of this for co-exisiting species and organic matter cycling?
How is organic matter utilized and transformed by benthic communities?
In order to address these research questions I use a variety of biochemical tools such as: stable carbon and nitrogen analyses, lipid and pigment biomarkers and compound-specific isotope analsyes.
- Can we detect changes in Arctic ecosystems?
- Climate change, food webs, energy flow and ecosystem function in the deep sea
