Abstract
Comparisons of temperature variability in Deep sea, Coastal and Terrestrial localities around 42.2 degrees latitude and -63 degrees longitude. The marine data come from the World Ocean Atlas and the Terrestrial data come from weather stations for the World Meteorological Organization. All data cover the same 30 year period of 1991-2020.

Description of the data and file structure
Data were obtained from the World Ocean Atlas (https://www.ncei.noaa.gov/access/world-ocean-atlas-2023/) for marine sites and and the World Meteorological Organization (https://www.ncei.noaa.gov/data/oceans/archive/arc0216/0253808/5.5/data/0-data/data-composite-primary-parameters-min24/) for terrestrial sites. Deep sea ecosystems (n=15) exhibit lower temporal variation in temperature compared with nearshore (n=10) and terrestrial (n=10) sites. Means and standard deviations of temperatures are presented for a 30-year period (1991–2020), using interpolated data from the World Ocean Atlas for coastal and deep sea locations and measurements from World Meteorological Organization weather stations for terrestrial sites. All sites were chosen at similar northern latitudes (deep sea: 42.125–42.875; coastal: 42.5; terrestrial: 42–42.985) to minimize latitudinal climate variation. Deep sea temperatures represent conditions at 2000 m depth, coastal temperatures were taken at 0 m depth, and terrestrial site elevations ranged from 4 to 396 m. Black triangles indicate the overall mean and standard deviation for each region, with deep sea locations in blue, coastal locations in light orange, and terrestrial locations in green.
