Drilling Within the Critical Zone

Hydrological 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.

Aeolian and Biogeochemical Transformations of Detrital Gold Morphology in the Pool Burn Basin, Central Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Pool Burn basin is a tectonic depression that became almost isolated from the regional drainage system by river reorientation during Pleistocene uplift of surrounding ridges. Consequently, detrital gold in the basin was largely locally derived, from supergene zones on orogenic deposits and recycled from paleoplacers in erosional remnants of Miocene

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

Mineralogy and Formation of a Platinum Placer Deposit, Southern South Island, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Placer platinum group minerals (PGM), with subordinate detrital gold, have been concentrated in Pleistocene coastal sands near the present Foveaux Strait shoreline. This study characterises the PGM in what is New Zealand's only identified PGM deposit.

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...
