The Global Ecosystem Dynamics Investigation, or GEDI, instrument on the International Space Station acquires lidar waveforms to observe the Earth’s surface in 3D. The GEDI lidar measures the height and density of objects, so it provides information such as surface elevation and tree canopy height and cover.

Kīlauea summit gas team fieldwork – October 22, 2022
HVO volcanic gas specialists make sulfur dioxide (SO~2~) emission rate measurements downwind of the eruption within Halema‘uma‘u crater, Kīlauea summit. This video shows the typical fieldwork involved with measuring SO2 emission rates, during which HVO scientists drive traverses beneath the plume in the closed area of Hawai‘i Volcanoes National Park.

Eyes on Earth Episode 81 - Tour of the EROS Radome
The Landsat satellites have been collecting Earth imagery for more than 50 years. A key piece of equipment that moves the data from the spacecraft to the archive so researchers can use it is the antenna at the EROS Center. The antenna and its radome have a fascinating history of their own that adds to the overall Landsat story.

Monthly update of activity at Yellowstone Volcano for October 1, 2022
Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone in this monthly update for October 1, 2022.
The update comes to you from Artist Paintpots in Yellowstone National Park. The paintpots are acid sulfate springs, one of three different types of thermal features in Yellowstone.

September 27, 2022 — Continued endogenous growth of crater floor at Kīlauea summit
This timelapse sequence shows one image per day since March from the B1cam webcam on the east rim of Halema‘uma‘u, at the summit of Kīlauea. The images show that the floor of Halema‘uma‘u has been growing endogenously.

September 12 overflight video of Kīlauea summit
A routine helicopter overflight of the summit of Kīlauea provided airborne views of the lava within Halema‘uma‘u crater. The active lava lake is limited to the western portion of the crater floor, near the main source of white fume. The remainder of the crater floor consists of solidified lava flows.

Eyes on Earth Episode 80 - ECOSTRESS and Carbon
ECOSTRESS, which stands for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, collects land surface temperatures in an effort to answer questions about plants’ use of water. The NASA Land Processes Distributed Active Archive Center (LP DAAC) at EROS has provided storage and distribution of ECOSTRESS data for four years now and counting.

Escanaba Trough Expedition: Biological Communities
The familiar saying “good things come in small packages” holds especially true for deep-sea biological communities at hydrothermal vents, including those at Escanaba Trough, a seafloor spreading center located almost 200 miles off the northern California coast.

August 18, 2022 — Timelapse of lava lake motion in Halema‘uma‘u, Kīlauea
This time-lapse sequence is shown at 100x speed and shows the motion of the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Lava enters the lake at the west end (bottom of image) and flow steadily towards the east end, where the crust is consumed along the lake margins.
