Index of Nutrient files

Index of LTER lakes nutrient files

Nutrients:

One file for each lake each year containing date, depth, nitrate, phosphate and ammonia in um/L. One file for each lake each year containing date, depth, particulate nitrogen, carbon and phosphorus. The third fourth and fifth letters in all file names of nutrient data files are the lake names. The last two or three letters vary by file type. Files containing Nitrate, Phosphate and ammonium data end in the letters nut, or nt. Files containing particulate nitrogen, phosphorus, and carbon end in pnts, or pnt.

Starting in 2000 there is now a yearly file with all the lakes sampled.
