Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

Large‐Scale Submarine Sediment Waves at Macauley Caldera Volcano: In Situ Evidence of High‐Flux, Syn‐Eruptive Submarine Transport

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.
