SUMMARY:NOAA Seminar Series: Mapping and monitoring turbidity in estuaries using remote sensing
DESCRIPTION:Title: Mapping and monitoring turbidity in estuaries using remote sensing and in-situ measurements \nSpeaker: Stephany Garcia\, NOAA EPP/MSI CESSRST-II Fellow at SDSU \nDate: August 9\, 20223 \nTime: 1:00 PM ET \nVenue: Virtual \nMeeting Link :  meet.google.com/xjr-zfee-aet \nPhone Number\n(‪US‬)‪+1 219-321-0478‬\nPIN: ‪651 945 406#‬ \nLearn more about the speaker \nAbstract: \nSatellite imagery of Southern California’s Tijuana River Outlet shows frequent turbid water plumes extending out into coastal water after storms and cross border flow events (Ayad et al.\, 2020). Turbid water has high concentrations of organic and inorganic materials that can carry harmful bacteria and pathogens (Warrick et al.\, 2012). In fresh and saline water systems\, such as estuaries\, water reflectance can reveal information about the biological productivity at different trophic states\, benthic environment suppression\, nutrient cycling\, and the overall habitat quality for water-dependent organisms (Barbier et al.\, 2011; Topp et al.\, 2020). However\, reflectance-based turbidity mapping is complicated by atmospheric conditions\, clouds\, and the reflectance of bottom materials in shallow water. Understanding the timing\, frequency\, and duration of turbid water events is often site-specific\, because of regional climate\, varying anthropogenic pressures\, sediment loading rates\, and geology (Elliott & McLusky\, 2002). For my NERTO\, a shallow water turbidity algorithm was used to identify turbidity hotspots in the tidal inland channels of TRNERR using the Sentinel-2 satellites. The goal was to quantify the accuracy of turbidity maps created from remote sensing by conducting Kayak Surveys and testing the water for suspended sediment concentrations (SSC) and Loss on Ignition (LOI). Initial findings revealed that ordering and receiving materials post-COVID was not possible in the course during a three-month NERTO period. Additionally\, because of high contamination levels in the TJR Estuary\, fieldwork was often prohibited. Moreover\, because the data sondes we are using have 6+ sensors\, equipment knowledge\, and troubleshooting became an essential part of my NERTO experience \n

SUMMARY:NOAA Seminar Series: Uncertainties in the retrieval of remote sensing reflectance from OC satellite observations
DESCRIPTION:Title: Uncertainties in the retrieval of remote sensing reflectance from OC satellite observations \nSpeaker: Eder Herrera Estrella\, NOAA EPP/MSI CESSRST-II Fellow at CUNY \nDate: August 9\, 20223 \nTime: 1:30 PM ET \nVenue: Virtual \nMeeting Link :  meet.google.com/xjr-zfee-aet \nPhone Number\n(‪US‬)‪+1 219-321-0478‬\nPIN: ‪651 945 406#‬ \nLearn more about the speaker \nAbstract: \nUncertainties in retrieving remote sensing reflectance\, Rrs\, from Ocean Color (OC) satellite sensors have a substantial impact on the performance of algorithms\, such as for the estimation of chlorophyll-a concentrations\, and inherent optical properties (IOPs). The impact is highest in the blue bands\, especially in coastal waters with low blue-band Rrs values. Sunlight propagates to the water and back to the top of the atmosphere (TOA) with the total radiance measured by the sensor capturing the radiances related to the instantaneous state of in-water conditions\, sky\, and sunlight reflected from the wind-roughened wave facets and light scattered on molecules and aerosols in the atmosphere. All these components are associated with uncertainties\, which together with the effects of the instrument noise and uncertainties in aerosol models in the atmospheric correction process\, contribute to uncertainties in the retrieved water-leaving radiance and remote sensing reflectance. Assuming that these uncertainties are mostly proportional to the corresponding radiances and taking advantage of the differences in the spectra of these radiances\, we analyzed the contribution of the components above to the total Rrs uncertainties in the SNPP-VIIRS level 2products for multiple scenes in the open ocean and coastal waters at different spatial resolutions. Results are complemented by data from several AERONET-OC sites and the VIIRS validation/calibration cruises and showed that the Rayleigh component (molecular scattering and surface effects) is the main source of 𝑅𝑟𝑠 uncertainties for any water type followed by water variability\, which has a bigger role in coastal areas\, while the contributions of other components including aerosol scattering are usually smaller \n

SUMMARY:NOAA Seminar Series: Remote sensing of anthropogenic debris in stream channels
DESCRIPTION:Title: Remote sensing of anthropogenic debris in stream channels \nSpeaker: Elena Aguilar\, NOAA EPP/MSI CESSRST-II Fellow at SDSU \nDate: August 22\, 20223 \nTime: 1:30 PM ET \nVenue: Virtual \nMeeting Link :  meet.google.com/ead-ypxo-gvb \nPhone Number\n(‪US‬)‪+1 219-321-0478‬\nPIN: ‪651 945 406#‬ \nLearn more about the speaker \nAbstract: \nInadequate management of anthropogenic waste is a challenge for coastal waters in the US-Mexico border region. Managing waste requires detecting and monitoring locations where uncontrolled disposal and debris accumulation occurs at high rates. Watershed-scale remote sensing can aid the understanding of the distribution\, pools\, and fluxes of plastic materials in pluvial systems. The Los Laureles Canyon watershed (LLCW)\, located in Tijuana\, Mexico\, is a large source of plastic pollution for the Tijuana River Estuary in Imperial Beach\, California. Through a combination of field\, laboratory\, and remote sensing methods\, we identified surficial plastic materials and waste hotspots in LLCW and 6 visually assessed the utility of spectral mixture models and WorldView-3 (WV3) shortwave infrared (SWIR) broadband imagery for plastic mapping. Field trash surveys conducted in LLCW reveal channel reaches have large scale waste patches (4-10m²) as a result of dumping. Laboratory reflectance spectroscopy was used to characterize the diversity of plastic reflectance and assess spectral signatures to inform multispectral image analysis. Samples processed to date show plastics have consistent absorptions at about 1210 nm\, 1410 nm\, 1660-1730nm\, and 2100-2300nm wavelengths\, depending on the polymer type. When convolved to the spectral response function of the WV3 sensor\, mean plastic reflectance retains prominent features between 1660-1730 nm and above 2200 nm wavelengths\, similar to an image endmember observed through principal components analysis of LLCW imagery. A spectral mixture model uses the matched filtering algorithm and selected image endmember to map built-environment plastic infrastructure and waste hotspots in areas explored during field visits. \n

SUMMARY:NOAA Seminar Series: Arctic Feedbacks on Trace Gas Compositions.
DESCRIPTION:Title: Arctic Feedbacks on Trace Gas Compositions. \nSpeaker: Francia Tenorio\, NOAA EPP/MSI CESSRST-II Fellow at SDSU \nDate: August 22\, 20223 \nTime: 1:30 PM ET \nVenue: Virtual \nMeeting Link :  meet.google.com/ead-ypxo-gvb \nPhone Number\n(‪US‬)‪+1 219-321-0478‬\nPIN: ‪651 945 406#‬ \nLearn more about the speaker \nAbstract: \nPolar ecosystems are warming faster than any other region on Earth (IPCC 2022)\, posing many implications for tundra landscapes. The accelerated warming in the Arctic influences the rate and movement of nutrients in the soil and water\, plant growth\, microbial decomposition\, and thawing of the permafrost processes that occur across the landscape. This can release greenhouse gases (GHG) into the atmosphere. Since permafrost regions hold over half of all the estimated organic carbon stored in Earth’s soils and 40-60 Pg of nitrogen\, it is essential to understand changes across the Arctic landscape and how this influences climate dynamics locally and globally. Thermokarst formations\, which typically occur during the thawing of the permafrost\, may be sources of emissions in tundra landscapes and a reflection of rapid climate change. Microtopographic features\, particularly bare soils\, may be a hotspot for GHGs. The webinar will present a mapping effort of such features via remote sensing techniques in a tundra ecosystem near Utqiaġvik\, Alaska\, emphasizing the monitoring GHGs from such features. \n
