Seasonal Patterns in Nutrients, Carbon, and Algal Responses in Wadeable Streams within Three Geographically Distinct Areas of the United States, 2007-08. National Water Quality Assessment Program.

摘要

The purpose of this report is to describe seasonal patterns in nutrients, carbon, and algal response variables for the 22 sites sampled monthly for 1 year during 2007 or 2008 and to describe how relations between nutrients and biological responses vary seasonally. Samples were collected during 2007 in the Ozark Plateau (OZRK) study area and during 2008 in the Upper Mississippi River Basin (UMIS) and Upper Snake River Basin (USNK) study areas. The scope of this report is limited to describing the seasonal pattern trends observed during the 1 year of sampling in each of the three National Water Quality Assessment (NAWQA) study areas.
