Galway Bay bathymetry comparison from Admiralty Chart and LiDAR datasets.

open access: yes, 2012
The primary objective of this paper was to test the sensitivity of numerical models to bathymetry datasets. Bathymetric datasets used were from; 1) Admiralty Charts and 2) LiDAR & Multi- Beam Echo Sounder surveys. The bathymetries were examined by comparing the contour maps, mudflat extents, basin volumes at various stages of the tide, tidal ...

Evolution of the Transantarctic Basin (Southern Gondwana): Insights From Quantitative Sandstone Petrography

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The deposition of the sandstone sedimentary succession of the Beacon Supergroup lasted more than 200 Myr (Devonian to Early Jurassic) in Victoria Land and nearby territories in the so‐called Transantarctic Basin, recording crucial events in the history of the Earth.

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Legacy and novel contaminants in surface sediments of Admiralty Bay, Antarctica Peninsula

open access: yesScience of The Total Environment
Despite being one of the most remote areas on the planet, the Antarctic continent is subject to anthropogenic influences. The presence of various groups of contaminants, including persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs), has been documented in the region over the past decades.

Improving SAR‐Based Classification of Arctic Lake, Bay and Lagoon Ice by Accounting for Under Ice Water Salinity

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Arctic lake, bay and lagoon ice regimes play a crucial role in understanding permafrost stability, hydrology, and carbon cycling in permafrost regions. This study integrates field and Synthetic Aperture Radar (SAR) data from Sentinel‐1 to improve the classification of Arctic lake, bay and lagoon ice regimes, with a particular focus on the ...

Churchill and Germany: A ‘Special’ Relationship

open access: yesHistory, Volume 111, Issue 395, Page 237-254, March 2026.
Abstract No other country defined the trajectory of Churchill's political career more than Germany, a country of which he had little direct knowledge but which he either sought to emulate, accommodate or oppose throughout his time in politics. This article traces Churchill's relationship with Germany from his entry into politics at the beginning of the

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

open access: yesLand Degradation &Development, Volume 37, Issue 4, Page 1330-1352, 28 February 2026.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Ecological and Genetic Insights Into Antarctic Fairy Shrimp, Branchinecta gaini Daday, 1910 (Branchiopoda: Anostraca) Populations on King George Island, Antarctica

open access: yesFreshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT The Antarctic fairy shrimp (Branchinecta gaini) is the largest inland animal in Antarctica and a key component of its freshwater ecosystems. Despite its broad distribution, little is known about its population structure, habitat tolerance, and potential vulnerability to climate change. This study investigated the occurrence, genetic structure,

Impact of Estuarine Exchange Flow on Multiple Tracer Budgets in the Salish Sea

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract Estuarine exchange flow regulates aspects of estuarine biogeochemical processes; however, other tracer‐specific factors can also play an important role. Here, we analyze realistic simulations from a coupled physical‐biological model to quantify volume‐integrated budgets of heat, total nitrogen (TN), and dissolved oxygen (DO) in the Salish Sea ...
