Nelson Sherry | PhD Candidate

I am a Ph.D. Student in the Oceanography Dept.
I started in January of 1996.

My advisor is Paul J. Harrison .

I am working on determining the role played by heterotrophic bacteria in the carbon cycling of the Sub-Arctic Pacific.

Winner of the 2000 Department of Earth and Ocean Sciences Golden Mouse Award !

My question consists of essentially 3 parts:

1) What is the size of the bacterial carbon pool; and what are the rates of transfer in and out of that pool relative to depth, season, and location along Line P?

2) What factors control the bacterial carbon pool size and the rates of carbon transfer to and from that pool?

3) How do the properties measured and inferred from parts 1 and 2 relate to other physical and biological properties such as temperature, salinity, POC, PON, DOC, primary productivity, virus numbers, flagellate numbers, etc.

My work is being done in conjunction with the Canadian JGOFS program and I have been participating in the joint CJGOFS/WOCE line P cruises.

I graduated with a BS in 1991 and an MS in 1995, both in biology from the University of Oregon, Eugene, OR.
