SUMMARY:NOAA Seminar Series: Marine Heatwaves in the Tropical Atlantic: Detection\, Characteristics\, and Trends in a Warming Ocean.
DESCRIPTION:Title: Marine Heatwaves in the Tropical Atlantic: Detection\, Characteristics\, and Trends in a Warming Ocean.\n \nDate:  August 20\, 2025\, 10:00 am – 11:00 am ET\n \nPresenter(s): Keneshia Hibbert\, CESSRST-II Graduate Fellow\n\nRemote Access: : https://meet.google.com/jyf-ojbj-wzn\n\nAbstract: Marine heatwaves (MHWs) are prolonged periods of anomalously warm sea surface temperatures (SSTs) that can have profound ecological and climatic consequences. This study presents a comprehensive assessment of MHW characteristics across the tropical Atlantic Ocean from 1982to 2024\, employing a consistent methodology based on the framework established by Hobday et al. (2016). Daily SST data were analyzed against a seasonally varying climatological 90th percentile threshold to detect MHW events and quantify key metrics\, including event frequency\, duration\, and spatial extent. Our domain-level approach identifies and tracks contiguous periods of elevated SSTs across the entire basin\, applying strict temporal criteria to ensure scientific robustness. Results reveal distinct seasonal and interannual variability in MHW occurrence\, with several multi-week events observed during the boreal summer and fall months. The spatial extent of MHWs was found to fluctuate considerably over time\, occasionally covering large portions of the tropical Atlantic Basin. These findings provide a critical foundation for understanding the temporal evolution and physical characteristics of marine heatwaves in a region of high climate sensitivity. This work lays the groundwork for future efforts to investigate the role of large-scale climate modes and anthropogenic warming in shaping the dynamics of MHW in the tropical Atlantic.
