Michelle Wagner

Michelle Wagner is in her first year of master’s study at the City College of New York. Her research interest is in monitoring the responses of coastal systems to natural and anthropogenic stressors. After graduating from the City College of New York, Michelle joined the Tzortziou Bio-optics lab at CCNY. Her work utilized HPLC and microscopic analysis as well remote sensing data to characterize seasonal shifts in phytoplankton community composition in the Long Island Sound estuary and increasing intensity in red tide events and other HABS.

I am very happy to have been a part of the Cornell 2024 Satellite Remote Sensing Training Program this summer. As someone who is new to the world of satellite data processing, I could not have asked for a better introduction. Dr. Monger’s strong expertise as well as his guidance and encouragement gave me the confidence to tackle hard problems. The course not only introduced me to Python programming but also provided a range of tools for handling satellite data. It significantly broadened my perspective and deepened my understanding of satellite remote sensing. I really enjoyed this course and would recommend it to anyone pursuing satellite remote sensing and ocean color analysis. I would like to say thank you to Dr. Bruce Monger and OCB for this amazing experience!

Alba Guzmán Morales was born in Arecibo, Puerto Rico. She received her B.S. in Biology and M.S. in Biological Oceanography from the University of Puerto Rico Mayagüez Campus in 2019 and 2024, respectively. Her research focused on using satellite imagery to study water clarity trends in Puerto Rico to evaluate management efforts in a watershed. As a NOAA Cooperative Science Center in Atmospheric Sciences and Meteorology Fellow, she evaluated the applicability of a NOAA Kd490 product by comparing it with in situ Kd490. She has also been involved in Unmanned Aerial Vehicle research to measure salinity.

Cornell's Satellite Remote Sensing course was what I expected and more. While I had previous experience processing satellite data the course provided me with tools I hadn’t yet had the opportunity to use in my work. It was amazing to process and visualize L1 to L2 ocean color, SST, wind, and altimetry data. I am deeply thankful to the great instructors Dr. Bruce Monger and Jillian Steinmetz, to the colleagues I met during the course as well as OCB for supporting this opportunity. Let the research continue!

Kiwanuka Moses: I’m a second-year Earth Systems Science PhD Student working under Dr. Sridhar Maruthi Balaji Bhaskar at Florida International University. My research uses remote sensing and machine learning to estimate water quality parameters for inland lakes (Okeechobee and Victoria). The goal is to develop monitoring algorithms based on Landsat 8 OLI and Sentinel 2 MSI images. These models will be correlated with results from NASA SeaDAS software.

The Cornell Satellite Remote Sensing course was a great experience. I learned multiple ways of downloading datasets, cleaning them, and channeling them to a particular study area. I also learned how to use Python command lines for image processing using NASA SeaDAS and better understood the different components of oceanography (Physical and biological) as a field. There was a great improvement in my programming skills. I enjoyed every moment with Dr. Bruce Monger and Ms. Jillian Elaine, the TA. Their patience regarding the questions directed at them was exceptional. I recommend this course to anyone interested in remote sensing and ocean color. Special thanks to Ocean Carbon and Biogeochemistry (OCB) for the sponsorship and for making this a reality for me.

María del Alma Concepción Rodríguez's journey into water resources began during her undergraduate studies at the Polytechnic University of Puerto Rico. Earning a Bachelor of Science in Chemical Engineering and a master’s in environmental management, she immersed herself in internships and projects related to the water industry. These experiences profoundly impacted her, highlighting water's vital role as the driving force of nature and the center of life.

As she advanced to her PhD in Civil Engineering, now going into her third year, María del Alma’s passion for water conservation grew stronger. She became particularly concerned about the potential contamination from regulated wastewater disposals in the waters surrounding the Caribbean Island of Puerto Rico. This concern sparked a compelling desire to delve deeper into understanding their impacts. Her doctoral research is a testament to this dedication. It focuses on how effluent discharges affect oceanic waters and aims to develop a comprehensive evaluation methodology. María del Alma leverages innovative GIS techniques to identify contamination hotspots through spatial data analysis. Her goal is to create geospatial models that visualize current and future scenarios, providing a clearer picture of the potential impacts on our waters.

Through her work, María del Alma strives to protect and conserve our natural environment, recognizing that safeguarding water resources is not just important but essential.

Imagine learning about the intricacies of satellite remote sensing while collaborating with peers, all within the vibrant academic atmosphere of Cornell University—that was my experience in a nutshell. The 2024 Cornell Satellite Remote Sensing Summer Course was an enriching experience that deepened my technical knowledge and connected me with a network of passionate individuals in the remote sensing community. The course’s rigorous curriculum laid a strong foundation for my understanding of the field and opened my eyes to the vast remote sensing applications. We delved into the core principles of remote sensing, how the satellite data is collected, and the processing of such data using coding. Dr. Bruce Monger was an excellent instructor who guided us throughout the course while getting a better understanding of each of our investigations. Teaching assistant Jillian Steinmetz was knowledgeable and always willing to assist us. The course featured lectures and hands-on workshops where you were given exercises to work on the computer using Python and SeaDAS to understand the processing of satellite imagery. One of the most exciting moments of the course was the hands-on experience with satellite data—using advanced software to process and analyze the data and turn the raw information into meaningful insights for my PhD research. Participating in the 2024 Cornell Satellite Remote Sensing Training Program was a transformative experience that broadened my horizons and passion for using innovative technology in real-world water applications.

Looking for easy data access to high quality time-series data? SPOTS is out!

Posted by mmaheigan

· Thursday, April 18th, 2024

Whether we aim to disentangle anthropogenic driven trends from naturally variability or we want to assess and improve our ocean model’s capabilities to correctly display changes in time, all require high-quality observational data from multiple fixed time-series data. Until now access to these data was difficult, time-consuming, and often required solving multiple data challenges before these data were fit for the purpose. Following the successful examples set by well-known ocean synthesis products, the idea for SPOTS – the Synthesis Product for Ocean Time-Series – was born from this need to address these challenging.

The recently published SPOTS pilot provides biogeochemical essential ocean variables from 12 ship-based fixed time-series scattered around the globe covering the period from 1983 until 2021. An extensive quality assessment enables the straightforward detection of method changes, and in combination with further introduced data quality indicators, the pilot enhances the inter- and intra-station comparability of the included time-series stations. The stations in SPOTS represent unique open ocean and coastal marine environments in the Atlantic, Pacific, Mediterranean, Caribbean, and the Nordic Seas. More than 100,000 water samples are harmonized into one consistent, FAIR, and readily available data synthesis product.

The SPOTS pilot drastically reduces the amount of time needed to obtain high quality and comparable time-series data from multiple programs around the globe. SPOTS facilitates a variety of applications that benefit from the collective value of biogeochemical time-series observations, complementing relevant products for the global ocean that don’t offer the temporal variability and quality of data that fixed time-series programs have. This pilot gives a first glance of what SPOTS has to offer and hopefully many updates of a sustained time-series living data product, SPOTS, will follow.

BGC Argo Webinar #9 Leveraging BGC-Argo and machine learning https://youtu.be/4JtfFKbsXqc	2024 December 18 10am Pacific/1pm Eastern	Yui Takeshita (Monterey Bay Aquarium Research Institute, U.S.) An update on the GO-BGC Program Jonathan Sharp 4-D BGC-Argo data products seminar announcement Colette Kelly (Woods Hole Oceanographic Institution) - Low-pressure storms drive nitrous oxide emissions in the Southern Ocean Guillaume Liniger (Monterey Bay Aquarium Research Institute) - Two decades of increase in Southern Ocean net community production revealed by BGC-Argo floats	Kelly abstract: The Southern Ocean is net source of the potent greenhouse gas nitrous oxide to the atmosphere. Marine nitrous oxide emissions are difficult to constrain, however, due to their sharp gradients and small scales of variability in both space and time. In the Southern Ocean, where extratropical cyclones create conditions conducive to high air-sea gas flux, traditional shipboard sampling is unlikely to capture the full extent of nitrous oxide emissions due to the inability to sample in the centers of such storms. Here, we propose that the Southern Ocean nitrous oxide source is almost double the magnitude of previous estimates, based on machine learning-derived nitrous oxide observations from biogeochemical Argo floats. Our results suggest that the low-pressure centers inside extratropical cyclones amplify air-sea nitrous oxide disequilibria and create brief, intense pulses of nitrous oxide to the atmosphere. We demonstrate further that taking these low-pressure centers into account, instead of assuming a barometric pressure of 1 atmosphere, increases the overall magnitude of the Southern Ocean nitrous oxide source by a significant margin, explaining the discrepancy between previous work and our higher, more comprehensive estimate. Our results imply that the Southern Ocean plays a significant role in the global nitrous oxide cycle and may be a weaker net sink of greenhouse gases than previously thought. Liniger abstract: Nitrate is an essential nutrient for phytoplankton growth that is closely coupled to carbon cycling. Understanding the spatial and temporal variability of surface ocean nitrate is important for primary productivity and carbon export to the deep ocean. In this study, we developed a neural network constrained by the high spatial and temporal coverage of BGC-Argo floats to predict nitrate in a consistent way throughout space and time in the Southern Ocean, a key area for ocean carbon uptake and controlling global ocean nutrient distributions. Here, we show that annual net community production (ANCP), calculated from seasonal nitrate drawdown, reveals the greatest production around the 40-50°S meridional band. After correcting for physical and sampling biases, basin-wide ANCP averages 3.49 ± 0.11 PgC y-1, with a significant increase of 0.63% y-1 from 2004 to 2022. Our results demonstrate the potential of using machine learning constrained by BGC-Argo observations to study long term changes of biogeochemical processes in the ocean.	BGC Argo

BGC Argo Webinar #8 Comparing BGC-Argo observations with models https://youtu.be/6XclbUk2DAs	October 16, 11am Pacific/2pm Eastern	Yui Takeshita (Monterey Bay Aquarium Research Institute, USA) An update on the GO-BGC program Camila Serra-Pompei (Technical University of Denmark) Assessing the potential of backscattering as a proxy for phytoplankton carbon biomass Martí Galí Tàpias (Institute of Marine Sciences [ICM-CSIC], Spain) Constraining stocks and fluxes of Particulate Organic Carbon (POC) through the comparison between particulate scattering measurements and PISCESv2 model	Serra-Pompei: Assessing the potential of backscattering as a proxy for phytoplankton carbon biomass The particulate backscattering coefficient (bbp) has often been used as an optical proxy to estimate phytoplankton carbon biomass (Cphy). However, total observed bbp is impacted by phytoplankton size, cell composition, and non-algal particles. The scarcity of phytoplankton carbon field data has prevented the quantification of uncertainties driven by these factors. Here, we first review and discuss existing bbp algorithms by applying them to bbp data from the BGC-Argo array in surface waters (<10m) and show that errors can be large when the bbp signal is low. Next, we use a global ocean circulation model (the MITgcm Biogeochemical and Optical model) that simulates plankton dynamics and associated inherent optical properties to quantify and understand uncertainties from bbp-based algorithms in surface waters. In an ideal world where field data has no methodological uncertainties, the model shows that bbp algorithms could estimate phytoplankton carbon biomass with an absolute error close to 20% in most regions. Galí Tàpias: Constraining stocks and fluxes of Particulate Organic Carbon (POC) through the comparison between particulate backscattering measurements and the PISCESv2 model BGC-Argo data offers a great opportunity for model evaluation, optimization, and the development of improved parameterizations, ultimately furthering our mechanistic understanding. However, comparison between BGC-Argo observations and models requires careful consideration of the spatiotemporal scales that each of them can resolve. When using particulate backscattering (bbp) as a proxy for particulate organic carbon (POC), additional attention must be paid to the variability in the POC/bbp ratio, its uncertainty, and its underpinning biogeochemical drivers. In this talk I will present comparisons between bbp from BGC-Argo and simulated POC based on both 3D (Eulerian) and 1D (pseudo-Lagrangian) frameworks. I will discuss the potential and limitations of model parameter optimization using BGC-Argo bbp as the observational reference. Finally, I will explore the impacts of optimized model parameters on mesopelagic POC budgets and vertical fluxes in the PISCESv2 model.	BGC Argo

OCB-US CLIVAR Ecological Forecasting Workshop webinar https://youtu.be/8fL8YnyymAg	2022 January 11	Simone Alin (NOAA PMEL)	The Olympic Coast as a sentinel: Integrated social-ecological vulnerability assessment and co-developing ocean resource management tools with tribal and state managers As part of a regional vulnerability analysis, our team synthesized existing oceanographic data sets and model projections to understand how the frequency, duration, and severity of ocean acidification and co-stressor (warming, hypoxia) conditions may change between now and the end of the century and affect biological resources. Meanwhile, social scientists worked with Washington's coastal treaty tribes to identify the marine species of highest cultural and subsistence value to the tribes and to assess social vulnerability of tribal communities to changing ocean conditions. Ultimately the oceanographic synthesis and projections will inform tribal adaptation actions. On a related project, many of the same team worked with state and tribal managers to develop tools useful to managers of the Dungeness crab fishery in state and tribal fishing areas. In this talk, I will briefly describe scientific results and products of our collective work, but will focus as much on the challenges and lessons learned from working with this diverse team, consisting of natural and social scientists (working across academic institutions; federal, state, and tribal agencies) and tribal community members.
