isoscape {ecotraj}

isoscape dataset

Description

This data sets is a subset from Espinasse et al. (2020).

Format

isoscape is an object of class dataframe composed of 978 observations of 6 variables.

Latitude

Latitude coordinate of the station, in degrees

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.
