Carbon and nitrogen stable isotope values for lake trout from 6 different Arctic lakes near Toolik, Arctic LTER 1987 to 1988.

Abstract: 

Lake trout were analysed for carbon and nitrogen stable isotope values in 6 Arctic lakes near Toolik Lake at the Arctic LTER in 1987 and 1988. The fish were also analysed for age using otoliths.

Methods: 

All isotope samples are muscle tissue dried at 60 deg C. Total length and wet weight were measured in the field. Ages were calculated using otolith measurements.

Site Code: site of measurement
Date: in dd-mmm-yyyy
fishnum: reference number for each fish
del_15N: del 15N value per mil
del_13C: del 13C value per mil
length: total fish length in mm
weight: total wet weight in g
age: estimated fish age in years using otolith

CALCULATIONS
All isotope values are in per mil (o/oo) and are calculated as 13C or 15N (o/oo) = [(R sample/R standard)-1] x 1000, where R is (15N/14N) or (13C/12C). Results are reported versus atmospheric nitrogen or PDB as standards.
