DOCUMENTATION FILE: WAT-UNH-IP-catchments.doc
YEAR: 2001-2002
PI: Charles Vorosmarty
OTHERS: Wilfred Wollheim, Brian Pellerin
BRIEF DESCRIPTION OF DATA FILE: Nutrient data was collected
monthly between April 2001 and December 2002 in collaboration with volunteers
from the Ipswich R. watershed association.
All samples were collected on the same day. Samples were analysed for NO3, NO2, NH4, PO4, and Si at UNH using
Lachat methods. Headwater stream sites
included a range of land uses in the contributing area. Samples were generally collected on the last
Sunday of the month. In the XL file,
each date has its own worksheet.
KEYWORDS: ammonium, dissolved, nitrate, nitrogen, nutrient,
phosphate, phosphorus, silicate
SITE TYPE: Watershed
RESEARCH LOCATION: x
and y coordinates (meters) in MA State Plane NAD83. Sites were georeferenced to a gridded river network with 120m
grid sizes. X and Y coordinates reflect
slight shifts to ensure proper placement on the digital river network. Contributing area is listed in km2
