Nantucket Maria Mitchell Association Welcomes Shawn Sneddon and Jon Fajans as Featured Guests for August Science Speaker Series

August 8, 2024

NANTUCKET, MA — The Nantucket Maria Mitchell Association (MMA) announces that it will host Shawn Sneddon and Jon Fajans of Yellow Springs Instruments (YSI), a Xylem Inc. brand which serves as a leading provider of water measurement solutions, as featured presenters for its Science Speaker Series. Their presentation “Autonomous, Precise, and Real-Time Coastal Water Quality Monitoring” will take place on Monday, August 12 at 6pm EST. It will be presented in person at the Great Harbor Yacht Club, at 56 Union Street. The presentation will also be hosted via Zoom.


Due to its unique geographic, hydrographic, ecologic, and cultural setting, Nantucket Harbor has one of the last remaining healthy eelgrass (Z. marina) beds in New England. The shape of Nantucket Harbor forces incoming sea water to pass over the eelgrass beds, which sequester the water’s carbon dioxide. Seagrasses can consume more carbon dioxide per acre than rainforests, and noticeably lower the acidity of the water around them. The MMA believes the confluence of these factors also makes Nantucket Harbor one of the best locations to investigate the impacts of healthy eelgrass on the commercially valuable Nantucket bay scallop (A. irradians). Ocean and coastal water quality monitoring applications require both precise and rugged instrumentation that will withstand harsh environmental conditions and still output accurate data. Join Shawn Sneddon and Jon Fajans of YSI as they share about the science, logistics, and analytics of the EMM700 Bay Buoy and sensors that will be deployed in a continuous data collection and publication monitoring project, the first of its kind on Nantucket. This project will collect and publish continuous data on seawater acidity (pH), dissolved oxygen, temperature, total algae, dissolved nitrates, and salinity (conductivity). This data will create the "Mitchell Curve," a longterm, permanent record of ocean acidification in Nantucket Harbor.


Shawn Sneddon has over sixteen years of experience in the Oceanographic and Water Quality field, designing, integrating, and deploying a vast array of real-time monitoring systems with a heavy focus on custom system integration. After taking over the autonomous vehicle fleet in 2015, Sneddon is now one of the lead engineers for all things autonomous: performing hydrographic surveys, trainings, customer/sales support, and demos for customer applications. Sneddon started his career as a service and calibration engineer for Aanderaa before moving into a Systems Engineering role for the integrated systems and services division of YSI. He is currently the System Sales Engineer and Vehicle Specialist for YSI.


Jon Fajans earned a Bachelor’s degree in Health Sciences and served eleven years in the U.S Coast Guard as a Flight Surgeon’s Assistant. He earned additional Bachelor’s degrees in Zoology and Wildlife Ecology, and a Master’s degree in Fisheries and Aquatic Sciences studying marine invasive species at the Univesity of Florida. Since then, Fajans has been the manager of the SEAKEYS Monitoring Program in the Florida Keys National Marine Sanctuary as a scientist for the Florida Institute of Oceanography, Dive Safety Officer for the University of Belize, and President of C‐ARMS Inc., a small marine research consulting company. He served as a scientific support coordinator in the NOAA Subsurface Monitoring Unit for the Deepwater Horizon incident response and has installed ICON buoys throughout the Caribbean on a joint Caribbean Community Climate Change Center‐NOAA AOML project. Fajans came to Xylem in 2015. He now serves as manager for Ocean & Coastal Applications covering the Americas and Caribbean.

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • April 28, 2025
Lynn, Ap. 25 1869  My dear President, I am not sure I told you how long I must be away from the College. If I took only the Sunday’s rest, it would be possible for me to reach the Obs. By Tuesday, but I feel the need of more than one day of quiet, before I enter upon the new and incomprehensible life before me . . . William Mitchell died on April 19, 1869 and for the first time, Maria Mitchell was alone. Save for her trip to the southern United States and Europe in 1857 and 1858, her father was always by her side. She did not know much of a day in her life without him nearby and she knows that. It was difficult for her – and her siblings worried about her and this new world she was now in. She had been – expect for that trip – the caregiver for both of her parents. Her mother, Lydia Coleman Mitchell, died in 1861 on Nantucket and Maria had cared for her as well. She was the child who became the caregiver of the family – both in her youth as her siblings sought her out for care, humor, love, and adventures while their mother was busy with younger children and household duties – and then her parents as the only child who did not marry and remained by their sides.
