SUMMARY:NOAA Seminar Series: Hybrid Aviation Weather Climate Interface - HAWCI
DESCRIPTION:[vc_row][vc_column][vc_column_text css=””]\n\nTitle: Hybrid Aviation Weather Climate Interface – HAWCI\n \nPresenter(s): Drake Valencia\, CESSRST II Graduate Fellow  \nRemote Access: Video call link:  https://meet.google.com/cpt-znyu-stw\n\nAbstract: \n Crosswind\, ceiling\, and visibility constrain Southern California aviation\, but forecast guidance covers one airfield and one variable at a time\, leaving no quantified regional picture. METAR observations from 53 ASOS and AWOS stations (2006 to 2025\, 10\,403\,137records) were paired with FAA NASR runway headings to resolve crosswind trigonometrically\, then reduced to lagged conditional probabilities for all ordered station pairs\, stratified by wind direction\, season\, month\, and time of day. The domain packs dozens of civilian and military airfields across varied terrain. Calm wind\, not wind direction\, dominates inland low-visibility conditions\, where rates run three to four times the directional-wind rate. Crosswind co-occurrence is strongest among coastal fields\, while ceiling and visibility co-occurrence tracks shared elevation and terrain rather than distance. \nThe results presented are from the NOAA EPP CSC NERTO graduate internship project conducted under the mentorship of Ivory Small\, National Weather Service\, San Diego Weather Forecast Office. This NERTO experience aligns with the NOAA Cooperative Science Center in CESSRST-II\, supporting the Center’s goal of conducting NOAA mission-aligned collaborative research to understand and predict changes in weather and atmosphere. This project\, titled HAWCI-Hybrid Aviation Weather Climate Interface\, addressed the research question: how often do Southern California airfields exceed operational crosswind\, ceiling\, and visibility thresholds\, and which other airfields follow\, and after how long? The work provides value to the scientific community and program stakeholders by converting two decades of routine observations into a quantified regional climatology and a standalone operational tool. Through this internship\, the student deepened their understanding of NOAA mission areas and gained enhanced skills in large-scale data pipeline development\, Python programming\, spatial statistics\, and operational software delivery. \n\n\n[/vc_column_text][/vc_column][/vc_row]

SUMMARY:NOAA Seminar Series: From Satellites to Cells: a comparison of methods to measure phytoplankton and Harmful Algal Blooms in Charleston Harbor
DESCRIPTION:[vc_row][vc_column][vc_column_text css=””]\n\nTitle:From Satellites to Cells: a comparison of methods to measure phytoplankton and Harmful Algal Blooms in Charleston Harbor\n \nPresenter(s): Emilia Lepe\, CESSRST II Graduate Fellow  \nRemote Access: Video call link: https://meet.google.com/udt-cpam-jyi\n\nAbstract: \nCharleston Harbor\, South Carolina\, isa tidally flushed estuary where phytoplankton respond to both tidal flushing and nutrient inputs from land. Harmful algal blooms (HABs) can degrade water quality\, so monitoring must cover both space and time. Point sampling cannot easily track blooms across the harbor\, and satellite ocean color is limited in turbid\, optically complex water where colored dissolved organic matter and sediment can mask chlorophyll-a signals. This 12-week internship at the Hollings Marine Laboratory provided training in methods that characterize phytoplankton across scales: scanning electron microscopy\, flow imaging with a newly installed FlowCam 8100\, high-performance liquid chromatography (HPLC)pigment analysis\, smartphone-based reflectance measurements with the HydroColorapp\, and Sentinel-2 satellite imagery processed with ACOLITE atmospheric correction and the chl_oc2 algorithm. On June 23\, 2026\, the chlorophyll-a map showed lower values around the Plum Island Wastewater Treatment Plant diffusers than in the surrounding harbor. This pattern may reflect reduced phytoplankton growth where the effluent carries fewer nutrients\, or an optical artifact of rising bubbles and fresher water at the diffusers; a time series with optical correction and in-situ validation is needed to tell them apart. Electron microscopy showed that species-level identification depends on fine cell structure that no satellite pixel can resolve\, illustrating the trade-off between spatial coverage and taxonomic resolution and why these methods are most useful in combination. \n\n\n[/vc_column_text][/vc_column][/vc_row]
