Data Description

Metrics related to spatial and temporal frequency and magnitude of bottom temperature habitat.

Introduction to Indicator (Please explain your indicator)

See "Thermal Habitat Gridded" for cell-based calculations. Many deep water benthic and demersal exhibit thermal preferences for metabolic, reproductive, and growth processes. Temperatures above these thermal presences may impair these processes. Temperature thresholds between 0.5C and 30C at 0.5C intervals. Data from 1993-01-01 to 2024-09-10 were obtained from the CMEMS' GLORYS12V1 global reanalysis product. Daily cell-based metrics include: the number of days exceeding a temperature limit (nDays), the number of consecutive days exceeding a temperature limit (nDays_consecutive), the sum of temperatures above a temperature limit (degree_days), and the proportion of each area that exceeds a temperature limit (percent_area). These daily metrics are summarized with a minimum (_min), maximum (_max), mean (_mean), median (_median), and standard deviation (_sd).
