SST Trend Analysis (1982-2024)

Built a basin-scale climate indicator for the Bay of Bengal by quantifying 42 years of sea surface temperature trends from NOAA OISST V2.1 using Earth Engine and non-parametric statistics.

  • Generated annual median SST composites (1982–2024) in Earth Engine and exported multi-band GeoTIFFs for basin-wide and pixel-level analysis.

  • Applied Mann–Kendall and Sen’s slope to estimate a statistically robust warming rate (~0.022 °C/year, ~0.92 °C in 42 years), mapping spatially uniform and highly significant warming across the basin (Z > 3).

  • Interpreted results in the context of marine heat exposure, cyclone energetics, and regional climate risk, demonstrating ability to translate EO-based climate indicators into management-relevant narratives.
