Overview

Paleofire records reveal fire activity characteristics in the Western Mediterranean using marine sediment analysis, indicating significant relationships with climate and fuel types.

Key Points

  • The aim is to refine interpretations of paleofire records by linking microscopic charcoal characteristics to fire regimes.
  • Analyzed 277 marine surface sediment samples from the eastern Atlantic Ocean and western Mediterranean Sea.
  • Investigated correlations between microscopic charcoal morphology and characteristics of fire regimes, climate, and fuel types on adjacent land.
  • Squared microscopic charcoal particles indicate correlations with forest fires.
  • Elongated particles are associated with burning of open and mixed vegetation, reflecting tree vs grass burning.
  • Microscopic charcoal concentrations are linked to fuel type, climate, fire frequency, and burned areas.
