Photon Phrightday: Mount Terror

10/28/2022
NASA’s ICESat-2 mission measures the height of land, ice, and water by bouncing photons of light off their surfaces and timing how long it takes them to return to the spacecraft. Take a closer look at this fearful photon cloud … if you dare!

GLOBE Observer: ICESat-2 and GLOBE Trees Challenge 2022

09/14/2022
What do trees, tree height, lasers, and a NASA satellite called the Ice, Cloud, and land Elevation Satellite-2 have in common? Brian Campbell (610/GST) discusses this in his recent blog post “Four Years of ICESat-2 and the Upcoming NASA GLOBE Trees Challenge 2022: Trees in a Changing Climate.”

NASA GLOBE Land Cover Challenge 2022: Land Cover in a Changing Climate

07/26/2022
The Global Learning and Observations to Benefit the Environment (GLOBE) Program invites you to take part in our upcoming Land Cover Challenge: “Land Cover in a Changing Climate.”

The photos you take using The GLOBE Program’s GLOBE Observer app document the current land cover and may also show evidence of land cover or land use change in the area. We especially encourage you to look for places you know have changed (or where you know change is coming), and put any information about the reasons or timing for that change in the field notes section. While existing land cover databases (such as the 50-year record from the Landsat satellite) may be able to indicate where change is happening, they don’t always include the reasons why those changes occurred, so any local, on-the-ground knowledge you share with us can be especially helpful.

Study Investigates Glacier Slope

12/18/2020
Denis Felikson is lead author on a study looking at how gentler bed topography, may have a greater impact on glacier flow than previously thought.

Notes from the Field Blog: Polarstern at the North Pole

09/23/2020
Sea ice geophysicist Melinda Webster is blogging from the RV Polarstern, an icebreaker ship locked in Arctic sea ice for the MOSAiC expedition. Webster will use MOSAiC data as a blueprint to evaluate and extend the seasonal capability of data from NASA’s ICESat-2 satellite for sea ice research.

Earth Expeditions: An Active Arctic – Where Sea Ice Meets the Midnight Sun

07/24/2020
In the early 1900s, Ernest Shackleton attempted to travel across Antarctica, but as they neared the continent his ship became stuck in an pack of sea ice and was slowly crushed before it reached the landmass. Over 100 years later and on the opposite side of the globe in the Arctic, researchers in the massive, double-hulled icebreaker, Polarstern, are also stuck in a pack of sea ice – but this time on purpose. And this ship isn’t sinking any time soon.

Earth Expeditions Blog: Operation IceBridge – Glaciers Aren't Forever

07/08/2020
Flying a plane over Alaska’s vast landscape provides a birds-eye view of some incredible sights. Bears run across frigid streams, moose trample through mounds of snow, and golden eagles own the air above ice-capped mountains. Glaciers cut paths through these mountains, leaving lakes and rivers in their wake. These glaciers are especially interesting to scientists who want to learn more about climate change in a region that is changing more than any other.

Earth Matters Blog: Research Roundup -- Depicting Change Across Earth’s Frozen Places

06/15/2020
A series of research papers in recent months shows that we know more than ever before about the ice on our land and covering the seas. In case you missed them, here’s a look at some of the notable findings. Many are based on data from NASA’s ICESat-2 satellite, which just over a year ago released to the public more than a trillion new measurements of Earth’s height.

Notes from the Field Blog: Departure

05/06/2020
Hi there, from 39,000’. I’m Melinda Webster, a sea ice geophysicist at the University of Alaska Fairbanks’ Geophysical Institute. I’m on my way to the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition as the Ice Team Lead for Leg 4. Funded under NASA’s New Investigator Program, I’ll be using MOSAiC data as the ultimate blue print to evaluate and extend the seasonal capability of ICESat-2 data for sea-ice research.

Notes from the Field Blog: Polar Bear Visits Polarstern

04/28/2020
This past week we had the first polar bear sighting of leg 3. In the early morning hours, a curious male polar bear walked through the Central Observatory, checked out a few installations, played with a rubber fender, and continued on to about 800 meters from the ship.

Notes from the Field Blog: Ice Coring Mondays

04/21/2020
The main task I am involved with here on MOSAiC is the drilling of sea ice cores. Each week, a group of 10 scientists from the Sea Ice, Ecology, and Biogeochemistry teams goes out to two different “Dark Site” locations on the floe to drill ice cores that will be used in a variety of different experiments back on the ship. We call this large weekly effort “Coring Monday.”
