Walter "Walt"

Telesetsky

Walter Telesetsky 1938 – June 16, 2025

Walter "Walt" Telesetsky- beloved father, husband, and friend- departed in the early morning hours of June 16, 2025, from Maryland on his final cruise to reunite with his mother Nellie (Nadezhda) Kralka, wife Sharron-Dawn, and his daughter Stephanie Ann.
Walter was known affectionately as "Walt" or "Wally" by those who loved him. His 87 years of life were filled with joy, sorrow, laughter, tears, and an abundance of love.
Born 1938 in Massachusetts, Walt grew up in a loving home where, despite limited means, his mother and father created a warm and caring environment, always with the smell of homemade Slavic cooking in the air. Some of his fondest childhood memories included visits to Revere Beach in the 1940s with his mother and doting aunts, Olga, Pauline, and Annie.
He attended Shurtleff Junior High and Chelsea High School, where he played in the school band, sang in the German Club, and was known for his great sense of humor. His schoolmates considered him a natural comedian.  Walt was the first in his family to graduate from college, earning a degree in Mechanical Engineering from Northeastern University. During a college internship in Milwaukee, he met the love of his life, Sharron-Dawn, in a chance encounter while moving out of an apartment she was moving into. Ten months later, after a long-distance love, they were married on July 15, 1961.
That same year, Walt also earned his MBA from the University of Chicago. He began his career at MITRE Corporation, working on significant projects like a data buoy system for the Coast Guard. But in 1970, he made a life-changing decision to join public service at the U.S. Department of Commerce, where he would remain for 32 years serving the public interest.
He joined the U.S. Department of Commerce's Environmental Science Services Administration (ESSA) headquartered in Rockville, Maryland as a physical scientist to work on ESSA's mission to coordinate research data collection to understand global environment phenomena. When  ESSA was reorganized as the National Oceanic and Atmospheric Administration, Walt's first projects were  to coordinate across scientists, collaborate with other agencies, and to cooperate with other countries to promote environmental monitoring. This was the beginnings of the first international effort to measure and document the global effects of climate change.
He worked on developing plans for a coordinated "Global Environmental Monitoring System" (GEMS) before the first intergovernmental meeting on the environment held in Stockholm, Sweden in 1972. The concept behind GEMS was to create joint mechanisms to monitor the atmosphere, oceans, land, and biology at the earth system level. Walt promoted US policy to develop a focused international organization for coordinating environmental monitoring activities that would be based at the United Nations. This policy work was realized with the creation of the United Nations Environment Program.
He was responsible for coordinating NOAA's engagement in the "Man in the Sea" program which focused on determining and responding to the environmental effects of human-triggered changes to the ocean. His work included designing a long-term undersea research program that would involve research submersibles and a proposed Continental Shelf Laboratory Program focused on marine biology, ocean chemistry, commercial fishing, pharmacology, bioacoustics, and marine geology.
He was awarded the Department of Commerce's Silver award for "outstanding achievement in planning, managing, and coordinating a unique international scientific  experiment" as the Coordinator of the U.S. Global Atmospheric Research Program's Atlantic Tropical Experiment Project (also known as GATE). This project's purpose was to better understand convective systems, air-sea interactions, the equatorial currents, and upper ocean dynamics.   Involving  5000 researchers and other staff, 40 ships, a dozen aircraft, 20 fixed buoys, drifting buoys, land-based weather stations, and satellites to collect data, the project was launched in the summer of 1974 and collected data for one year. At the time, it was the largest and most complex international meteorological/oceanographic program of its kind, involving 14 core nations, including the USSR, the US, Brazil, Senegal, and several European states. Walt coordinated the US involvement in this global experiment across 5 agencies.
In 1980, Walt was involved in preparing a US/China joint research cruise program on sedimentation patterns within the Yangtze River estuary as the first US government vessel to visit China in 30 years. Throughout his career, he continued to promote bilateral research cooperation, including as the Coordinator for the U.S. and Japan Cooperative Program in National Resources and the Chairman of the U.S.-Japan Marine Resources and Engineering Coordination Committee.
In the 1980s and 1990s, he shifted focus to improving weather systems within the U.S. As Director of Operational Systems for the National Weather Service, he led the automation of weather stations by networking hundreds of field stations and helped launch the NEXRAD (Next Generation Radar systems), which dramatically improved storm forecasting and early warnings across 164 sites. For this, he received the Department of Commerce Gold Medal and recognition from the Federal Aviation Administration and the US Air Force for improving aviation safety. The Director of the National Academies of Sciences  credited Walt "with the success of all of the systems of the modernized National Weather Service."  Walt's operational work has become the foundation for today's precision forecasting.
Known for his integrity, humor, and leadership, Walt brought energy and kindness to his colleagues and often lightened the office mood with his collection of themed neckties.
In addition to his distinguished career, Walt was a devoted father to his wife and two daughters. Unless he was travelling for work, his family could count on him to be home for dinner. He selflessly supported the joy of his children by designing scavenger hunts, creating unforgettable Christmases, timing summer swim meets, planning fun weekend excursions, and helping with science fair projects.
After retiring in 2002, Walt took to the seas and began over a decade of travel that took him and Sharron-Dawn across the Pacific and the Atlantic to Europe, Canada, New Zealand, and Australia.  They sailed through the Panama Canal and crossed the Arctic Circle. When Sharron-Dawn's health declined, Walt became her loving caretaker and ensured that she lived her final years with dignity.
Even after losing his daughter Stephanie Ann in 2020, Walt found joy in small things: road trips with his daughter Anastasia, Christmas light shows, time at the gym, crossword puzzles, chats with neighbors,  bowls of ice cream, walks in the neighborhood, live music in the town square, a tasty piece of wild caught salmon, a slice of watermelon, a cup of coffee, a football game or an episode of The Amazing Race.
In his final months, Walt bravely faced an undiagnosed metastatic cancer. Despite surgery, a stroke, and intense pain, he remained strong in spirit until the end and continued to send love and wishes of joy for his family.
Walt is survived by his daughter Anastasia, sons-in-law Matthew and Bob, and nieces Brenda, Marsha, and Melody.
It truly was an amazing race.
