SUMMARY:NOAA Seminar Series: Creating a METAR Climatology Targeting Gradients and Trends Between METARS in the Southwestern U.S. to Examine Impacts on Southern California Weather
DESCRIPTION:[vc_row][vc_column][vc_column_text css=””]\n\nTitle: Creating a METAR Climatology Targeting Gradients and Trends Between METARS in the Southwestern U.S. to Examine Impacts on Southern California Weather\n \nPresenter(s): Jose Hurtado\, CESSRST II Graduate Fellow  \nRemote Access: Video call link: https://meet.google.com/egy-frvh-dth\n\nAbstract: \nCarbon cycling is driven by plant biological activity (root respiration\, photosynthesis\, respiration due to decay)\, climatic and meteorological factors (pressure\, precipitation\, ambient air temperature)\, and the interaction of these two sets of variables. However\, ecology research field stations can have data gaps due to equipment failures or human interference (thieves or trespassers). For example\, the Sky Oaks Field Station in Warner Springs\, CA has sensors for barometric pressure\, temperature\, relative humidity\, wind speed\, and direction\, as well as atmospheric carbon cycling data. This NERTO internship was to develop a Linear Mixed Effects Model for the interpolation of missing barometric pressure and ambient air temperature values at the Sky Oaks Field Station (Warner Springs\, CA) based on METAR data from the National Weather Service stations surrounding the Sky Oaks Field Station as archived from the Iowa State University’s data hub\, Iowa Environmental Mesonet. This inverse distance weighting (IDW) interpolation method used geographic data from the United States Geological Survey 3DElevation Program\, which improved model accuracy. In addition\, one of the Eddy Covariance Towers at the Sky Oaks Field Station was restored to collect gas flux and meteorological data. The Linear Mixed Effects Model produced for barometric pressure was overall highly significant (p=0.007503)\, but the model’s mean absolute error needs improvement\, as it is above the acceptable value of 1 millibar (1.21 millibar). The Linear Mixed Model for the Sky Oaks Field Station temperature failed to find significant correlations between the Sky Oaks Field Station measurements\, and its mean absolute error was 2.60 F(1.44 C) \n\n\n[/vc_column_text][/vc_column][/vc_row]

SUMMARY:NOAA Seminar Series: Leveraging Machine Learning and Artificial Intelligence Approaches to Improve Harmful Algal Bloom Monitoring and Forecasts
DESCRIPTION:[vc_row][vc_column][vc_column_text css=””]\n\nTitle: Leveraging Machine Learning and Artificial Intelligence Approaches to Improve Harmful Algal Bloom Monitoring and Forecasts\n \nPresenter(s): Haniel Cordero Nieves\, CESSRST II Graduate Fellow  \nRemote Access: Video call link: https://meet.google.com/out-xrvc-baz\n\nAbstract: \nHarmful algal blooms (HABs) in the Chesapeake Bay are challenging to characterize from satellite observations because of optically complex waters\, mixed phytoplankton communities\, variable environmental conditions\, and limited coincident field observations. This NERTO project developed a reproducible framework integrating historical phytoplankton observations\, NOAA satellite-derived algal bloom products\, geospatial analysis\, ecological information\, and machine-learning methods to support future AI-assisted discrimination of diatom- and dinoflagellate-dominated events. Field observations were matched with georeferenced satellite imagery and evaluated through a structured quality-control workflow addressing mixed pixels\, land contamination\, clouds\, missing data\, non-detect conditions\, saturation\, and coordinate inconsistencies. Of 31\,531 field-to-satellite records evaluated\, 860were initially classified as valid\, while neighboring-pixel analysis identified additional potentially recoverable observations. A preliminary Mini U-Net segmentation model demonstrated the feasibility of the approach but also revealed limitations associated with automatically generated labels\, motivating development of an interactive expert-review tool for event validation\, masking\, and labeling. Ecological analyses additionally explored seasonal phenology and environmental variables as potential features for future multimodal models \n\n\n[/vc_column_text][/vc_column][/vc_row]

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]

SUMMARY:NOAA Seminar Series: Integrating technology and imagery into evaluations of coral reef condition
DESCRIPTION:[vc_row][vc_column][vc_column_text css=””]\n\nTitle: Integrating technology and imagery into evaluations of coral reef condition\n \nPresenter(s): Neidibel Martinez\, CESSRST II Graduate Fellow  \nRemote Access: Video call link: https://meet.google.com/uoq-gcdw-toa\n\nAbstract: \nCoral reef structural complexity supports habitat and ecological function\, so accurate measurement is essential for monitoring and restoration. In-water surveys face time\, logistical\, and safety constraints\, creating a need for scalable approaches such as large-area imaging (LAI) and Structure-from-Motion (SfM) photogrammetry. NOAA needs consistent workflows to monitor restoration areas\, integrate imagery from different platforms\, and distinguish ecological change from methodological variability. Using the SfM section of NOAA’s Mission: Iconic Reefs LAI guidance as a reference\, this NERTO project developed a reproducible framework for comparing diver- and ROV-based imagery while quantifying processing variability. The analysis used imagery from reef restoration sites\, a relevant setting for fine-scale structural monitoring. We processed images in Agisoft Metashape using different alignment\, depth-map quality\, and filtering configurations. Reconstructions were screened using checkpoint RMSE\, reprojection error\, coverage\, point density and confidence\, completeness\, noise\, processing time\, and file size. We compared leading products as standardized digital elevation models in R using a common region of interest and surface complexity ratio. Higher-detail reconstruction produced approximately four times more points and a larger file but changed surface complexity by only about 3%. Preliminary diver–ROV results showed broadly similar structural patterns\, but the areas were not spatially paired and therefore cannot demonstrate platform agreement. These findings provide NOAA with a stronger QA/QC basis for selecting efficient processing settings and designing paired comparisons that support reproducible\, scalable coral reef restoration monitoring. \nThe results presented are from the NOAA EPP CSC NERTO graduate internship conducted under the mentorship of Dr. Shay Viehman at NOAA’s NCCOS Beaufort Laboratory\, NC. This project supports the NOAA CESSRST-II mission of understanding and predicting environmental changes\, particularly in oceans and coastal ecosystems. The project investigated how variations in SfM processing parameters and diver- versus ROV-based imagery influence the accuracy\, consistency\, and efficiency of coral reef structural measurements\, with the goal of developing standardized workflows for reproducible coral reef restoration monitoring. \n\n\n[/vc_column_text][/vc_column][/vc_row]
