Description: 
Delta-15N of PN (permil vs. air-N2) on first filter GF/F (nominal pore size 0.7um), prefiltered with 53um mesh, size range = 53 to 0.7um; filter punches not acidified before analysis. Note there is no P15N_GF75 data, all samples from the second filter were below detection, detection limit ~0.75 micromol N. Analytical uncertainty 0.2 permil
