Profile bio

About John A. Callahan

I am an interdisciplinary climate scientist working with NOAA's National Ocean Service (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) through Ocean Associates, Inc (OAI). My current research and work on operational products relates to sea level rise trends and projections, drivers and predictability of flooding, impact metrics, tidal theory and predictions, subseasonal to decadal prediction of climate and coastal flooding, coastal hazards due to weather and climate, among several other projects. (Past projects and activities listed here: https://drive.google.com/file/d/1Ym9YjwlHlVKGRT_w_980nJ5mjcyK52Hb/view?usp=drive_link.)While at NOAA and at my previous position at the Delaware Geological Survey at the University of Delaware, my work is service-driven, providing scientific guidance to national, state and local governments, natural resource managers, citizens, and others related to the safety and well-being due to risks from climate and weather. I enjoy these cross-discipline working groups and have had some excellent experiences working with extremely knowledgable and talented people, nationally through the National Climate Assessments, technical body of the NOAA Coastal Iunundation Task Force, and the Predictability, Predictions, and Applications Interface (PPAI) panel of US CLIVAR, as well as a few local activities, as a member of the Delaware State Climate Office, the Delaware Climate Technical Advisers Committee, and the Advisory Committee on Climate Change in the Delaware River Basin.

Listed skills include Gis, Remote Sensing, Spatial Analysis, Geography, and 29 others.
