SUMMARY:NOAA Seminar Series: Mapping Cumulative Impacts of Essential Fish Habitat Consultations in the Pacific Islands Region
DESCRIPTION:Title: Mapping Cumulative Impacts of Essential Fish Habitat Consultations in the Pacific Islands Region\n \nPresenter(s):  Amy Carrillo \nDate: 11 August 2025\, 3:00 pm – 4:00 pm ET\n \nRemote Access: Google Meet joining info \nVideo call link: https://meet.google.com/prg-psrb-moa \nAbout Speaker:  Amy Carrillo \nAbstract: The cumulative impacts of federally funded projects\, reviewed by the Essential Fish Habitat (EFH) team\, on EFH in the Pacific Islands region were visualized and evaluated. Using data from the Environmental Consultation Organizer (ECO)\, covering projects from 2017 to the present\, interactive dashboards and a story map were created to visualize the spatial distribution and intensity of these projects across the region. Three tools were created\, first a dashboard that displays all the EFH consultations as points covering the Pacific Island region to allow for visualization of project locations. Second\, on Oahu\, where each consultation action area is mapped as polygons\, scored for adverse impacts on EFH\, and supplemented with detailed information on the type of activity\, impact level\, and other relevant data. Finally\, on Honolulu Harbor\, presenting a story map of one of Oahu’s most heavily impacted and managed areas\, which also hosts a large coral nursery. By processing over 500 project records and creating these tools\, the project provides a comprehensive overview of the scale and impact of federal activities on EFH. The dashboards and story maps are designed to support decision-making by offering accessible tools for conservation efforts and the EFH team’s effective coastal resource management.

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.

SUMMARY:NOAA Seminar Series: Spatial Resolution Impacts on Remotely Sensed Product Uncertainty and Representativeness
DESCRIPTION:Title: Spatial Resolution Impacts on Remotely Sensed Product Uncertainty and Representativeness \nPresenter(s): Biajani Gonzalez\, CESSRST II Graduate Fellow  \nGoogle Meet :  https://meet.google.com/ugm-keyg-pgr\n\nAbstract: Satellite remote sensing\, while providing broad geographic coverage\, faces limitations in spatial resolution for detailed benthic mapping\, particularly in coastal regions such as Puerto Rico. Small unmanned aerial systems (UAS) offer a promising solution due to their ability to capture high-resolution imagery with flexibility. This study examines the impact of spatial resolution and classifier training strategies on the accuracy and consistency of benthic habitat classifications derived from drone-based imagery. It determines the optimal airborne sampling parameters ” balancing effective spatial resolution and flight parameters ” when using UAS for marine habitat mapping. Using high-resolution RGB orthomosaics (0.036 m/pixel) collected via UAS and upscaled to coarser resolutions (0.5 m to 10 m)\, we assessed the classification performance of coral\, sand\, seagrass\, and substrate using Support Vector Machine (SVM) classifiers under four case-study scenarios. Spatial metrics (total area\, patch count) and accuracy assessment indicators (self-transition and Critical Success Index) were applied to quantify classification degradation across scales and scenes. Results show fine-scale features\, especially coral and seagrass\, rapidly degrade beyond 1 meter\, while more homogeneous classes\, such as sand and substrate\, remain relatively stable.
