Performance of a data-driven technique applied to changes in wave height and its effect on beach response

Water Science and Engineering, 2016
In this study the medium-term response of beach profiles was investigated at two sites: a gently sloping sandy beach and a steeper mixed sand and gravel beach.

Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

Sedimentology, EarlyView.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, EarlyView.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

Finding Stars: Mapping the Geography of the World's Scientific Elites

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract Scientific excellence is clustering ever more tightly in a few ‘superstar’ cities. Four—New York, Boston, London and the San Francisco Bay Area—now host 12% of the world's top scientists. In contrast, the Global South remains largely absent, with the notable exception of Beijing's dramatic rise.

Shoreline retreat and beach nourishment are projected to increase in Southern California

Communications Earth & Environment
Sandy beaches in Southern California are experiencing rising coastal erosion due to changes in precipitation patterns and urban growth. As a result, beach nourishment is necessary for mitigation.

Tidal movement of sandy beach macrofauna

Wetlands Australia, 2010
This paper investigates possible changes in the organisation of the intertidal macrofauna community of Arrawarra Beach, NSW, over a range of tidal heights. The beach was divided into seven levels at low tide and 10 core samples for fauna were taken at each level during both high and low tide and at two evenly spaced tidal stages in between.

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, EarlyView.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

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

Finding the Best Nursery: How Habitat Features Shape Juvenile Snapper (Chrysophrys auratus) Density

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
This study examines habitat preferences of juvenile Australasian snapper (Chrysophrys auratus) in northeastern New Zealand, analysing data from 113 stations across structured and unstructured habitats. We investigated how juvenile snapper densities were influenced by environmental factors, including prey availability and physical habitat features ...
