Weather Rescue at Sea: Recovering Historical Weather Observations From 19th Century British Naval Ships

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
We present the Weather Rescue at Sea dataset, generated from a citizen‐science project which transcribed millions of weather observations contained in 19th Century UK Royal Navy ship logbooks. This corrected and quality‐assured dataset will enhance historical reconstructions of the pre‐modern climate by providing more input meteorological data ...

Drone‐imaging assisted genome‐wide association studies reveal key quantitative trait loci for emergence and late blight resistance in tetraploid potato

open access: yesCrop Science, Volume 66, Issue 2, March/April 2026.
Abstract Solanum tuberosum L. (potato) is the world's most important vegetable crop, and developing improved cultivars is paramount for global food security. The efficacy of the genomic prediction models that accelerate breeding and genome‐wide association studies (GWAS) depends on large, high‐quality phenotypic datasets, which are often associated ...

High‐resolution LiDAR and stereo‐DEMs for debris flow analysis in the Western Ghats, India: Sediment volume computation and run‐out modeling

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The 2020 Pettimudi debris flow in the Western Ghats of India killed 70 people. Our study using stereo‐DEM, UAV‐based LiDAR data, and field data estimated the sediment loss as 17 × 104 m3. Abstract Computation of sediment volume and accurate modeling of run‐out using high‐resolution digital elevation models (DEMs) are essential for assessing debris flow
