Pleistocene and Holocene Mobility of Detrital Platinum in Southern New Zealand: Review and Regional Synthesis

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Detrital platinum group minerals (PGM) are rare and distinctive in Pleistocene–Holocene sedimentary systems of the southern South Island, thereby enabling tracking of their long‐distance transport for ∼200 km. The first ∼100 km of transport involved Pleistocene glaciofluvial processes southwards down the Waiau River, where PGM (principally Pt–Fe and Ru–

The Challenges of Domestic Wastewater/Sewage Systems for Māori Communities

open access: yesKōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
The development of domestic wastewater systems in contemporary Aotearoa New Zealand has presented a significant challenge for Māori communities. While those communities have supported attempts to address the pollution of land and waterways through modern treatment methods, the solution has included continuing discharges of sometimes untreated and often

Carbon source and weather in coastal North Carolina

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The increasing frequency of extreme weather events, including tropical cyclones, is altering the delivery and quality of organic matter (OM) exported from landscapes to estuaries. However, the mechanisms regulating these shifts, especially during multi‐year climatic oscillations, remain poorly understood.

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 323-348, June 2026.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

open access: yesSmartBot, Volume 2, Issue 2, June 2026.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

A Structured Review of Selenium Pollution in Global Aquatic Environments: Sources, Levels, and Co‐Pollutants

open access: yesEnvironmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Despite its nutritional and industrial significance, selenium (Se) is considered a pollutant in aquatic environments owing to its toxicity at elevated concentrations, which potentially cause environmental degradation and adverse health effects in humans and local biota.

Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).
