Two-million-year-old Ice Provides Snapshot of Earth's Greenhouse Gas History
News
Thursday November 07, 2019
Two-million-year old ice from the Allan Hills region of Antarctica recently uncovered by a team of researchers provides a clearer picture into the connections between greenhouse gases and climate in the ancient past and is expected to help scientists understand future climate change. In a recent edition of the journal Nature, a group of scientists described how they used air trapped in the bubbles in ice as old as two million years to measure levels of the greenhouse gases carbon dioxide and methane.
Celebrating 50 Years of Women's Contributions to Polar Research
News
Tuesday October 29, 2019
On October 16, 17, and 18, Ohio State University hosted a symposium entitled "Women in Antarctica: celebrating 50 years of exploration", marking the first deployment of women as researchers with the NSF-managed U.S. Antarctic Program. Speakers included surviving members of that expedition; the head of the Antarctic Program; two women who hold key roles in science support for the Program; and former and current female researchers.

Hear From OPP-funded Antarctic Scientists Aboard the R/V Laurence M. Gould
The Inner Space Center (ISC), located at the University of Rhode Island Graduate School of Oceanography, is a one-of-a-kind national facility that supports live ocean exploration through telepresence technology. At 7:00 pm Eastern on Monday, October 28, ISC will hold a Facebook Live event with researchers aboard the R/V Laurence M. Gould, one of two vessels chartered by the NSF-managed U.S. Antarctic Program.

Two Former U.S. Antarctic Program Women Scheduled to Carry Out First All-female Spacewalk Later This Month
NASA announced late this week that astronauts Christina Koch and Jessica Meir, who are both currently aboard the International Space Station, are scheduled, on October 21, to attempt the first all-female spacewalk. Koch previously worked at NSF's Palmer and Amundsen-Scott South Pole stations in Antarctica. Meir worked with researcher Paul Ponganis, of the Scripps Institution of Oceanography at the University of California, San Diego, her doctoral-dissertation adviser, to study the physiology of Antarctic emperor penguins.

Two Polar "Alumni", Both Women, Serving Aboard the International Space Station
Jessica Meir, formerly an NSF funded, U.S. Antarctic Program researcher and now a NASA - National Aeronautics and Space Administration astronaut, joined the crew of the International Space Station (ISS) earlier this week, temporarily increasing the orbiting laboratory's population to nine people, one of whom is fellow astronaut Christina Hammock Koch, who also served in the Antarctic Program and at NSF's Summit Station in Greenland.

Statement by Dr. Kelly K. Falkner: On the Passing of Adrian-Dahood Fritz
On behalf of all of us in NSF's Office of Polar Programs, I wish to express our deepest sorrow at the untimely loss of our former colleague and co-worker, Adrian Dahood-Fritz. Adrian and her husband, Andrew, were among those whose lives were cut short by the dive-boat fire off California's Santa Cruz Island earlier this week.

In Memorium: Umihiko Hoshijima, Antarctic Scientific Diver
Umihiko ("Umi") Hoshijima, a postdoctoral researcher in ecology and evolutionary biology at UC Santa Cruz, died in a diving accident while working on a research project in collaboration with the U.S. Geological Survey near Glacier Bay, Alaska, on Aug. 7, according to a university news release. He was 28.

IceCube Neutrino Observatory Upgrade
The IceCube Neutrino Observatory, the detector at NSF's Amundsen-Scott South Pole Station that identified the first likely source of high-energy neutrinos and cosmic rays, is getting an upgrade. On June 25, NSF approved the funding to upgrade IceCube, extending its scientific capabilities to enable IceCube to reach neutrino energies that overlap with the energy ranges of smaller existing neutrino detectors worldwide.

NASA Balloon Over Antarctica Tests Neutron Stars' Mettle
Neutron Stars are the dense remains of stars which, at the end of their "life," were not quite large enough to collapse into black holes. Gravity crushes the dying star, fusing electrons and protons together in the process and forming small stars made entirely of neutrons. It is the densest matter in the universe; a single teaspoon is estimated to weigh as much as 10 million tons.

PRI Shows How Seals Assist Scientists with Predictions of the Thwaites Glacier Collapse
Weddell seals dive almost 2,000 feet below the ocean's surface. Elephant seals (such as the one in this 2005 photo) go even deeper - more than 3,000 feet. That means if scientists equip them with sensors, the seals are ideal for measuring the ocean's temperature at different depths.

Independence Day on The Ice
Personnel at McMurdo Station, Antarctica used their lunch break on July 5 to celebrate Independence Day with a parade. Aside from taking place on a continent experiencing 24 hours of darkness, many things would have been familiar in any parade on a typical "Main Street USA": fire engines, baton twirlers, flags, and smiling and waving military veterans.

A Celebrity Chef's Passion for Science
Angela Zoumplis, a biologist at the Scripps Institution of Oceanography, earlier this week wrote on the opinion pages of the New York Times about a visit to a field camp in the McMurdo Dry Valleys by the late celebrity chef Anthony Bourdain. One of several researchers who discussed their work and Antarctic experience with Bourdain on and off camera at NSF's Lake Hoare Camp, she was initially a bit perplexed about why he had come to the southernmost continent.

Antarctic Stations Celebrate 2019 Midwinter's Day
In Antarctica, the winter solstice is the longest night of the year and marks the halfway point of winter. Since the time of the early explorers, those people who have chosen to stay and work in Antarctica during the long dark night have celebrated Midwinter's Day.

Researchers Uncover Trove of Ancient Fossils That Highlight Antarctica as an Evolutionary Crucible
The mountains of Antarctica may seem an unlikely place to find fish, but they were exactly what a team of paleontologists working along the edge of the Polar Plateau last winter were looking for. In a region now defined by dry rocky terrain poking up through vast sheets of thick ice, the five-member team spent much of December and January scouring the exposed landscape for the remains of ancient fish.

Large-scale Images of Antarctic Landscapes at the Natural History Museum of Los Angeles County
The Natural History Museum of Los Angeles County is hosting an exhibition of large-scale images of Antarctic landscapes by Diane Tuft, who was a 2012 participant in OPP's Antarctic Artists and Writers program. The exhibit, Frozen in Time, which opened on May 23 and runs through Jan. 20, captures "the landscape in abstract ways," according to the museum, "her 13 large-scale photographs illustrate a whole new perspective on Antarctica."
