Supplementary environmental point data: "A climate-associated multi-species cryptic genetic cline in the northwest Atlantic"
This is supplementary environmental data used in environmental population structure analyses:
"A climate-associated multi-species cryptic genetic cline in the northwest Atlantic"
This data is described in the methods as:
Temperature and
salinity data were aggregated to seasonal climatological data (averaged across
2002-2012) layers, effectively corresponding with winter (January – March),
spring (April – June), summer (July – September), and fall (October – December). Seasonal sea surface temperature (SST) and sea surface
salinity (SSS) were assembled at spatial resolutions interpretable to 1 km2
from Level 3 SST climatological satellite data, including Advanced Very
High Resolution Radiometer data (AVHRR Atlantic; compiled by Fisheries and
Oceans Canada) and global oceanographic climatological SSS composites (Tyberghein et al. 2012). Benthic temperature and
benthic salinity climatological data layers were assembled at spatial
resolutions interpretable to 8 km2 from a numerical climatological
model (GLORYS2V1) adapted to the study area by Fisheries and Oceans Canada. We
represented topographic complexity of the seafloor (interpretable to 1 km2)
by east–west and north–south components of aspect, slope, plan and profile
curvature, and rugosity (Sbrocco & Barber
2013). These
data layers were used as predictive surfaces for each of the five species
native to the range (Table 1).
From these data layers, we extracted point estimates
of each environmental variable for each genetic sample location to evaluate
genetic-environmental relationships. This dataset represents these point estimates.
