We have known for centuries that the earth and the sky have an intimate relationship.  

O鈥橦alloran has made it his mission to decipher the rhythmic, cyclical 鈥渃onversations鈥� between the land surface and the atmosphere of our world to better understand how and why they are connected. He climbs into the sky on four towers, up to 120-feet tall, scattered around the Lowcountry to listen. These days, he also treks to the quietest, most isolated parts of the wetlands, towing a customized trailer full of cutting-edge equipment to eavesdrop.

What he鈥檚 heard has been eye-opening 颅鈥� and sobering 鈥� for climate scientists, scholars and farmers.

O鈥橦alloran measures the emissions of gases like methane, carbon dioxide and nitrous oxide released by the soil and ways with advanced sensors housed in the mobile lab. Nitrous oxide and methane, particularly, can strongly influence the climate. Better understanding the soil鈥檚 role in releasing these gases can help landowners increase profitability and help public policymakers manage land and mitigate greenhouse gas emissions. O鈥橦alloran and his collaborators can use the data collected to, for example, valuate carbon credits in coastal wetlands and conservation easements on restored rice fields, or to understand how sea-level rise is affecting coastal ecosystems.

From the towers, which are stationed around Clemson鈥檚 Belle W. Baruch Institute of Coastal Ecology and Forest Science, O鈥橦alloran measures the exchange of carbon, water and energy between the Earth鈥檚 surface and the atmosphere. He works with a team of international scientists to create a global map measuring the cooling effect forests have by regulating the exchange of water and energy between the Earth鈥檚 surface and the atmosphere, potentially a valuable tool in efforts to mitigate climate change.

O鈥橦alloran hopes his innovative approaches to studying the climate and forests, which also include the use of drones and satellites, will attract more young researchers into joining him in this important work.
