Nutrient cycling in oligohaline sediments and marshes: Is denitrification a major sink for nitrogen?

Principal Investigator:

Start/End Year: 

1998 to 2000

Institution:

Co-Principal investigator:

Description: 

The primary objectives of this proposal are to apply a new direct measurement technique for denitrification to: examine approaches to determining system-wide denitrification estimates in the Choptank River subestuary and determine if oligohaline marshes are important sites for estuarine denitrification. Denitrification will be compared to N input terms available for this subestuary, as well as N sinks including marsh N storage and burial.
