Geomorphology of marine and glacio-lacustrine terraces and raised shorelines in the northern sector of Península Brunswick, Patagonia, Straits of Magellan, Chile

Journal of Maps, 2018
This paper illustrates a detailed geomorphological map (scale 1:50,000) of the marine and transitional terraces (glacio-lacustrine to marine) and raised shorelines linked to Holocene glacio-eustasy and neo-tectonics in the northern area of the Brunswick ...

Assessment of Empirical CPT–Vs Correlations using Direct‐Push Crosshole Data from Shallow New Zealand Soil Deposits

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
This article assesses the performance of multiple cone penetration test–shear wave velocity (CPT–Vs) correlations based on a database of over 2,100 CPT–Vs data pairs obtained from co‐located shallow (≤10 m) CPT soundings and direct‐push crosshole tests in New Zealand.

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.

Riverbank dynamics in a semi-arid fluvial environment: A study of the lower valley of Wadi Tamri (Atlantic Atlas, Morocco)

Investigaciones Geográficas
Riverbanks in semi-arid Mediterranean environments are dynamic features constantly shaped by natural factors and human interventions. Wadi Tamri’s lower valley, with its large alluvial plain, fragile terraces, and mixed marine/continental deposits, is a ...

Dust Deposition and Loess Accretion in New Zealand's South Island: Examining Links between Cold‐Climate Processes and Dust Production

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
We compared temporal variability in dust and loess accretion in New Zealand's South Island with glacial activity in the central Southern Alps, considered the main mechanism of silt production, in (i) a proximal loess deposit at Barrhill, Rakaia River and (ii) a distal dust record from a peat mire in Central Otago.

Geomorphology of the mouth of the Arosa estuary (Coruña-Pontevedra, Spain)

Journal of Maps, 2017
This paper presents a geomorphological analysis of the littoral zone of the Arosa-Pontevedra estuary mouth and identifies geomorphological units and categorizes them into morphogenetic systems.

Rangitīkei River Terraces Formed During the Otira Glaciation: Lithostratigraphic Type Sections, Review and Conceptual Model

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Rangitīkei Valley in the lower North Island of New Zealand contains flights of river terraces that are influenced by changes in sediment supply, stream power and base level associated with Quaternary climate events over the last ∼350 thousand years.

Hyperspectral optical signatures of iron‐limitation in a coastal upwelling system

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Iron‐limitation within the California Current System drives changes in phytoplankton taxonomic composition and photo‐physiology over a range of spatial scales. Here we demonstrate how these iron‐dependent signatures can be resolved, with high spatial resolution, using continuous ship‐board optical measurements.

Glacial geomorphology of the Brabazon & Butler Downs, Rangitata Valley, South Island, New Zealand

Journal of Maps, 2017
The inland valleys of New Zealand’s South Island were heavily glaciated during the last glacial cycle. Subsequent fluvial incision has eroded out glacial deposits from the valleys in many locations, making it difficult to reconstruct glacial dynamics and

Associating Local‐Scale Physical Habitat Assemblages With Reach‐Scale Stream Hydrogeomorphological Types in Mountain Headwater Catchments

River Research and Applications, Volume 42, Issue 3, Page 527-546, March 2026.
ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...
