- Longitude
Longitude coordinate of the station, in degrees
- d13C
delta 13C modelled value
- d15N
delta 15N modelled value
- station
station ID
- Year
Year corresponding to modelled stable isotope values
Details
Briefly, Espinasse et al. (2020) tested the application of isoscapes modelled from satellite data to the description of secondary production in the Northeast pacific. The output model fits in a 0.25° x 0.25° spatial grid covering the region spanning from 46 to 62°N and from 195 to 235°E and supporting delta 13C and delta 15N isoscapes from 1998 to 2017. The subset is composed of modelled delta 13C and delta 15N values of a 1° x 1° spatial grid from the original modelled dataset for 2013 and 2015.
