The Magmatic‐Hydrothermal System of the Three Sisters Volcanic Cluster, Oregon, Imaged From Field Gravity Measurements

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract From 2019 to 2024, gravity surveys were conducted at the Three Sisters volcanic cluster (TSVC), measuring 246 gravity sites using a spring relative gravimeter. We calculated the residual Bouguer anomaly and identified three main zones with negative anomalies, ranging from −4 to −8 mGal, located southwest and west of South Sister, within an ...

The Evolving Decline of Landfast Sea Ice in Northern Alaska and Adjacent Waters: Results from an Updated Climatology

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract We present a new 27‐year record of landfast sea ice extent in northern Alaska and adjacent waters, which uses ice chart data to extend a previous analysis based on synthetic aperture radar (SAR) imagery. This new climatology provides updated information on the decline of landfast ice in a region of the Arctic that has seen extensive losses of ...

Characterization of a Lava Plain NW of Ascraeus Mons, Mars, Through Surface Morphometric Analyses and SHARAD Subsurface Detections

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The Martian lava plains are characterized by their extensive, low‐relief surfaces, which are the result of numerous basaltic eruptions and feature a variety of volcanic landforms, including vents, cones, pits, and skylights. The combination of these features and impact craters yields a significant understanding of the planet's geological past ...

Synthetic aperture radar backscatter is influenced by bubbles at the ice/water interface of an Antarctic lake

Communications Earth & Environment
Synthetic aperture radar is an invaluable tool for monitoring lake ice. This study utilizes synthetic aperture radar to analyze the 2019-2023 backscatter time series of perennially ice-covered Lake Untersee in East Antarctica.

“Salt Tectonics” on Titan: Radial Labyrinths as Topographic Expressions of Solid‐State Flow

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Surface observations of Saturn's moon Titan revealed features characterized as dissected, elevated plateaus with high valley density known as labyrinth terrains. Of this terrain class, a subtype referred to as radial labyrinth is described as dome‐shaped uplifts with radial channel patterns.

An Automated Data Efficient Morphometric Approach to Define Global Lentic and Lotic Inland Waters

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Defining lentic and lotic system types is critical for understanding hydrological, ecological, and biochemical processes. Traditional classification methods rely on non‐generalizable site‐specific parameters such as visual characteristics, historical inventory, and residence time.
