A Targeted Approach for Mapping Groundwater Discharge to Surface Water and Fish Thermal Refuge in Four Lake Ontario Tributaries

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Understanding groundwater discharge to surface water is crucial for ecosystems, water quality, and resource management. A flexible methodology was developed to first predict and then identify cold‐water zones and significant groundwater discharge areas in four key Lake Ontario tributaries.

Drilling Within the Critical Zone

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
This review synthesises 30 years of critical zone drilling methodologies for studying subsurface weathering, water storage, and biogeochemical processes. We evaluate drilling techniques, sampling strategies, downhole logging, and long‐term monitoring approaches while addressing contamination control and core preservation challenges.

Forecasting Natural Gas Prices in Real Time

open access: yesJournal of Applied Econometrics, Volume 41, Issue 2, Page 139-155, March 2026.
ABSTRACT This paper provides a comprehensive analysis of the forecastability of the real price of natural gas in the United States at the monthly frequency considering a universe of models that differ in complexity and economic content. We find that considerable reductions in mean‐squared prediction error relative to a no‐change benchmark can be ...

Shallow Shear‐Wave Reflection Surveys in the Wellington Central Business District

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Seismic reflection profiling using shear waves provides constraints on the thickness of sediments beneath the Wellington Central Business District. Standard seismic methods were modified for urban environments where limited grassed areas are available and levels of cultural noise are high.
