Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

An Updated Modular Set of Synthetic Spectral Energy Distributions for Young Stellar Objects

The Astrophysical Journal
Measured properties of young stellar objects (YSOs) are key tools for research into pre-main-sequence stellar evolution. YSO properties are commonly measured by comparing observed radiation to existing grids of template YSO spectral energy distributions (

The Earth's Greatest Porous Media

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Nondetection of FAST and Parkes Follow-up Observation for 27 Parkes-discovered Fast Radio Bursts

The Astrophysical Journal
To investigate whether apparently nonrepeating fast radio bursts (FRBs) are truly one-off transients, we conducted systematic follow-up observations of 27 out of 81 nonrepeating FRBs identified in the Parkes Transient Database. Using 59.0 hr of data from

GRAIN: Mapping the World's Irrigation Canals and Why It Matters for Water, Food, and Climate

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The engineered channels that carry water from large dams and rivers to agricultural fields, known as irrigation canals, are the link between source (lakes and reservoirs) and sink (farmlands). These canals make cultivation of crops possible across millions of hectares of land.

Estuary Water Elevation Research (EWER) Dataset: Observational Data for Studying and Quantifying Water Level‐Related Hazards in Australia's Tidal Environments

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
A new dataset for studying tides and compound flood hazards in Australian estuaries. The dataset brings together disparate national and state agency records to improve coverage of estuarine systems, including upstream tidal rivers that are often excluded from ocean‐focused datasets.

Search for Young Stellar Objects within 4XMM-DR13 Using CatBoost and SPE

The Astronomical Journal
Classifying and summarizing large data sets from different sky survey projects is essential for various subsequent scientific research. By combining data from 4XMM-DR13, Sloan Digital Sky Survey (SDSS) DR18, and CatWISE, we formed an XMM-WISE-SDSS sample
