One of the challenges many teachers face year after year is a sense of working alone. Despite the constant interaction with students many questions often linger: Did the lesson stick? Will students carry this knowledge with them? Will it shape how they see and engage with the world? What can be easy to overlook is that teaching does not happen in isolation. Each classroom, or any other educational setting, is part of a much larger journey that learners travel. This journey extends through a network of educators, where each experience can build on the last. These interconnected networks, known as Connected Learning Ecosystems (CLEs), exist wherever learning happens. At their core, CLEs are the collective of people who contribute to a young person’s growth and education over time.
Educators at the August 2025 Connected Learning Ecosystems Gathering in Orono, ME engaged in discussion around using NASA data in their learning contexts. Recognizing this, NASA’s Science Activation Program launched the Learning Ecosystems Northeast (LENE) project to strengthen and connect regional educator networks across Maine and the broader Northeast. With a shared focus on Science, Technology, Engineering, and Mathematics (STEM), LENE brings together teachers, librarians, 4-H mentors, land trust educators, and many others committed to expanding scientific understanding, deepening data literacy, and preparing youth to navigate a changing planet. To support this work, LENE hosts biannual Connected Learning Ecosystem Gatherings. These multi-day events bring educators together to share progress, celebrate achievements, and plan future collaborations. More than networking, these gatherings reinforce the collective impact educators have, ensuring that their efforts resonate far beyond individual classrooms and enrich the lives of the learners they guide.
“I am inspired by the GMRI staff and participants. I never expected to get to do climate resilience-related work in my current job as a children’s librarian. I am excited to do meaningful and impactful work with what I gain from being part of this the LENE community. This was a very well-run event! Thank you to all!” -anonymous
This year’s Gathering took place August 12 and 13, 2025, in Orono, ME at the University of Maine (a LENE project partner). Nearly 70 educators from across the northeast came together for two amazingly energized days of connection, learning, and future planning. While each event is special, this summer’s Gathering was even more remarkable due to the fact that for, the first time, each workshop was led by an established LENE educator. Either by self-nomination or request from leadership (requiring little convincing), every learning experience shared over the conference days was guided by the thoughtful investigation and real life application of LENE Project Partners, CLE Lead Educators, and community collaborators.
Brian Fitzgerald and Jackie Bellefontaine from the Mount Washington Observatory in New Hampshire, a LENE Project Partner, led the group through a hands-on activity using NASA data and local examples to observe extreme weather. Librarian Kara Reiman guided everyone through the creation and use of a newly established Severe Weather Disaster Prep Kit, including games and tools to manage climate anxiety. Katrina Heimbach, a long time CLE constituent from Western Maine taught how to interpret local data using a creative and fun weaving technique. Because of the established relationship between Learning Ecosystems Northeast and the University of Maine, attendees to the Gathering were able to experience a guided tour through the Advanced Structures and Composites Center and one of its creations, the BioHome3D – the world’s first 3D printed house made entirely with forest-derived, recyclable materials.
Two full days of teachers leading teachers left the entire group feeling energized and encouraged, connected, and centered. The increased confidence in their practices gained by sustained support from their peers allowed these educators to step up and share – embodying the role of Subject Matter Expert. Seeing their colleagues take center stage makes it easier for other educators to envision themselves in similar roles and provides clear guidance on how to take those steps themselves. One educator shared their thoughts following the experience:
“This was my first time attending the LENE conference, and I was immediately welcomed and made to feel ‘part of it all’. I made connections with many of the educators who were present, as well as the LENE staff and facilitators. I hope to connect with my new CLE mates in the near future!” Another participant reported, “I am inspired by the … staff and participants. I never expected to get to do climate resilience-related work in my current job as a children’s librarian. I am excited to do meaningful and impactful work with what I gain from being part of the LENE community. This was a very well-run event! Thank you to all!”
Even with the backing of regional groups, many educators, especially those in rural communities, still struggle with a sense of isolation. The biannual gatherings play an important role in countering that, highlighting the fact that this work is unfolding across the state. Through Connected Learning Ecosystems, educators are able to build and reinforce networks that help close the gaps created by distance and geography.
These Gatherings are part of ongoing programming organized by Learning Ecosystems Northeast, based at the Gulf of Maine Research Institute, that fosters peer communities across the Northeast, through which teachers, librarians, and out-of-school educators can collaborate to expand opportunities for youth to engage in data-driven investigations and integrate in- and out-of-school learning.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A ship plows through rough seas in the Bering Sea in the aftermath of Typhoon Tip, one of the largest hurricanes on record. The Sentinel-6B satellite will provide data crucial to forecasting sea states, information that can help ships avoid danger. CC BY 2.0 NOAA/Commander Richard Behn Sea surface height data from the Sentinel-6B satellite, led by NASA and ESA, will help with the development of marine weather forecasts, alerting ships to possible dangers.
Because most global trade travels by ship, accurate, timely ocean forecasts are essential. These forecasts provide crucial information about storms, high winds, and rough water, and they depend on measurements provided by instruments in the ocean and by satellites including Sentinel-6B, a joint mission led by NASA and ESA (European Space Agency) that will provide essential sea level and other ocean data after it launches this November.
The satellite will eventually take over from its twin, Sentinel-6 Michael Freilich, which launched in 2020. Both satellites have an altimeter instrument that measures sea levels, wind speeds, and wave heights, among other characteristics, which meteorologists feed into models that produce marine weather forecasts. Those forecasts provide information on the state of the ocean as well as the changing locations of large currents like the Gulf Stream. Dangerous conditions can result when waves interact with such currents, putting ships at risk.
“Building on NASA’s long legacy of satellite altimetry data and its real-world impact on shipping operations, Sentinel-6B will soon take on the vital task of improving ocean and weather forecasts to help keep ships, their crews, and cargo safe”, said Nadya Vinogradova Shiffer, lead program scientist at NASA Headquarters in Washington.
Sentinel-6 Michael Freilich and Sentinel-6B are part of the Sentinel-6/Jason-CS (Continuity of Service) mission, the latest in a series of ocean-observing radar altimetry missions that have monitored Earth’s changing seas since the early 1990s. Sentinel-6/Jason-CS is a collaboration between NASA, ESA, the European Union, EUMETSAT (European Organisation for the Exploitation of Meteorological Satellites), and NOAA (U.S. National Oceanic and Atmospheric Administration). The European Commission provided funding support, and the French space agency CNES (Centre National d’Études Spatiales) contributed technical support.
Keeping current
“The ocean is getting busier, but it’s also getting more dangerous,” said Avichal Mehra, deputy director of the Ocean Prediction Center at the National Weather Service in College Park, Maryland. He and his colleagues produce marine weather forecasts using data from ocean-based instruments as well as complementary measurements from five satellites, including Sentinel-6 Michael Freilich. Among those measurements: sea level, wave height, and wind speed. The forecasters derive the location of large currents from changes in sea level.
One of the planet’s major currents, the Gulf Stream is located off the southeastern coast of the United States, but its exact position varies. “Ships will actually change course depending on where the Gulf Stream is and the direction of the waves,” said Mehra. “There have been instances where, in calm conditions, waves interacting with the Gulf Stream have caused damage or the loss of cargo containers on ships.”
Large, warm currents like the Gulf Stream can have relatively sharp boundaries since they are generally higher than their surroundings. Water expands as it warms, so warm seawater is taller than cooler water. If waves interact with these currents in a certain way, seas can become extremely rough, presenting a hazard to even the largest ships.
“Satellite altimeters are the only reliable measurement we have of where these big currents can be,” said Deirdre Byrne, sea surface height team lead at NOAA in College Park.
There are hundreds of floating sensors scattered about the ocean that could pick up parts of where such currents are located, but these instruments are widely dispersed and limited in the area they measure at any one time. Satellites like Sentinel-6B offer greater spatial coverage, measuring areas that aren’t regularly monitored and providing essential information for the forecasts that ships need.
Consistency is key
Sentinel-6B won’t just help marine weather forecasts through its near-real-time data, though. It will also extend a long-term dataset featuring more than 30 years of sea level measurements, just as Sentinel-6 Michael Freilich does today.
“Since 1992, we have launched a series of satellites that have provided consistent sea level observations from the same orbit in space. This continuity allows each new mission to be calibrated against its predecessors, providing measurements with centimeter-level accuracy that don’t drift over time,” said Severine Fournier, Sentinel-6B deputy project scientist at NASA’s Jet Propulsion Laboratory in Southern California.
This long-running, repeated measurement has turned this dataset into the gold standard sea level measurement from space — a reference against which data from other sea level satellites is checked. It also serves as a baseline, giving forecasters a way to tell what ocean conditions have looked like over time and how they are changing now. “This kind of data can’t be easily replaced,” said Mehra.
More about Sentinel-6B
Sentinel-6/Jason-CS was jointly developed by ESA, EUMETSAT, NASA, and NOAA, with funding support from the European Commission and technical support from CNES.
A division of Caltech in Pasadena, JPL contributed three science instruments for each Sentinel-6 satellite: the Advanced Microwave Radiometer, the Global Navigation Satellite System – Radio Occultation, and the Laser Retroreflector Array. NASA is also contributing launch services, ground systems supporting operation of the NASA science instruments, the science data processors for two of these instruments, and support for the U.S. members of the international Ocean Surface Topography and Sentinel-6 science teams.
