Biography

Dr. Thomas DeCarlo is an oceanographer whose research focuses on the resilience and vulnerability of coral reef ecosystems in the face of climate change. His work combines field expeditions, laboratory analyses, and advanced imaging techniques to understand how ocean warming, acidification, and biogeochemical processes impact coral growth and survival. DeCarlo has conducted research across the globe—from the Great Barrier Reef to the Red Sea and the Pacific Islands—using coral cores as natural archives to reconstruct centuries of ocean conditions.

Before joining Tulane University, Dr. DeCarlo served as an Assistant Professor of Oceanography at Hawai‘i Pacific University and completed postdoctoral research at the University of Western Australia and the Red Sea Research Center at KAUST. He leads Tulane’s Sclerochronology Lab, which develops innovative approaches to forecast coral bleaching and assess reef health under accelerating climate stress.

Research

Research Areas:

Coral Reefs, Anthropogenic Climate Change, Ocean Dynamics, Coastal Biogeochemistry, and Ocean Acidification.

Research Overview:

Dr. DeCarlo oversees the Sclerochronology Lab, which focuses on understanding how reef environments are responding to anthropogenic pressures. Current research projects include:

  1. Global-scale analyses of coral growth histories using skeletal cores
  2. Investigating coral reef hydrodynamics with unmanned aerial vehicles
  3. Studying coral reef microclimates
  4. Advancing oyster reef restoration efforts in Louisiana

The lab emphasizes open science, developing practices to make datasets not only accessible but also easily usable by other researchers and for K–12 outreach initiatives.
