The US academic research vessel RV Neil Armstrong departed from Nuuk, Greenland in early October. On the first leg of our journey, the science team’s initial purpose was to collect water samples and previously deployed instruments along a line of moorings at the southern entrance to Baffin Bay, a gateway between the Arctic and the north Atlantic. This line stretches from Sisimiut, on the west side of Greenland, to just off Cape Dyer, near the Canadian coast.
The South Pole Telescope and Event Horizon Telescope
The South Pole Telescope (SPT) is a 10 meter microwave telescope located at the Amundsen-Scott South Pole Station in Antarctica. It primarily observes the cosmic microwave background (CMB), which is a thermal remnant or “heat echo” from the Big Bang. In addition to the primary CMB camera in the SPT, there is also a secondary specialized sub-millimeter camera which allows the SPT to participate in the Event Horizon Telescope (EHT), a global array of radio telescopes which work together to act as one earth-sized “synthetic telescope” in order to image and study nearby supermassive black holes. By combining data taken simultaneously with the SPT and the other telescopes in the EHT array, we can learn about the gravitational dynamics of black holes, better understand high-energy jets, strong astrophysical magnetic fields, and other astrophysical phenomena that happen in the unique environment around black holes.

From the Blog
Our plane glides through the Endicott Mountains of the Brooks Range as we make our final descent into Anaqtuuvak. Accessible only by plane, Anaktuvuk Pass (“the place of caribou droppings”) is located 250 miles northwest of Fairbanks and is home to the only community of inland Iñupiat, Nunamiut, people [1]. Below, icy blue glaciers feed into a winding network of streams that snake through dense, green tundra and low-lying willows that line the banks of the Anaktuvuk River. From the air, the tundra is a verdant forest, but once on the ground the trees and shrubbery are no taller than 5-6 feet. The village stands out like a colorful flower within the greenery, blooming into view as we enter the valley. In Anaktuvuk, the roots of plants and people alike extend down into permafrost, the lifeblood of the ecosystem and holder of history.
In July 2024 I had the opportunity to visit Amy in person in Arizona. In the vlog of my trip, I share pictures of the work one of Amy’s colleagues is doing on a telescope that is going in a hot air balloon in Antarctica, we visit Kitt Peak Observatory, which is built on the tribal land of the Tohono Odham nation, and then Amy’s lab at the University of Arizona. You will also hear snippets of the songs I wrote for our Polar STEAM resource assignment.
As a high school science teacher, I’m always looking for ways to inspire my students with real-world science and deepen their understanding of our planet. The PolarSTEAM Educator Fellowship has been an extraordinary opportunity to merge my passion for polar environments with my teaching. Through this year-long virtual collaboration with T.J. Fudge, a research scientist at the University of Washington, I’ve been immersed in cutting-edge research on ice cores, allowing me to bring current polar science research to my students.
The Juneau Icefield is a group of interconnected glaciers just north of Juneau, Alaska that extends into British Columbia, Canada and covers an area the size of Rhode Island. Maybe you’ve heard of the Mendenhall Glacier? It is part of the Juneau Icefield! The Juneau Icefield Research Program (JIRP) has been collecting data on the icefield since 1948.
