Characterization and mapping of plant communities at Hennequin Point, King George Island, Antarctica

Polar Research, 2013
King George Island is the largest island and the principal area used for research bases in Antarctica. Argentina, Brazil, Chile, China, Poland, Russia, South Korea and Uruguay have permanent open bases on this island. Other countries have seasonal summer

Freshwater diatoms of the Ecology Glacier foreland, King George Island, South Shetland Islands [PDF]

Polish Polar Research, 2018
Diatom assemblages from small pools and creeks on the Ecology Glacier forefield have been investigated. It is the first study in the Admiralty Bay region after the thorough taxonomic revision of the non-marine Antarctic diatom flora.

Trichocera maculipennis (Diptera)—an invasive species in Maritime Antarctica [PDF]

PeerJ, 2018
Antarctica, with its severe conditions, is poor in terrestrial fauna species. However, an increase in human presence together with climate change may cause an influx of non-native species. Here we report a significant increase in colonized area of one of

Nickel-copper deposit at Funter Bay, Admiralty Island, Alaska [PDF]

, 1942
From abstract: The nickel-copper deposit near the north end of Admiralty Island, about 18 miles in an airline west of Juneau, in southeastern Alaska, consists of a basic sill which averages somewhat more than 100 feet in thickness. The sill, which dips eastward, is intrusive into a thick sequence of phyllite and various types of schist. The rock of the

Penguin colonies and weather in Admiralty Bay in a colder year

INCT-APA Annual Activity Report, 2010
Climate change will affect many species in the next decades. Antarctic seabirds are of special concern given their dependence on the balance of sea ice-caps. The objective of this paper is to present information about weather and penguin colonies in the last extreme cold summer of 2009/2010. We verified the average temperature in November (beginning of

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

Journal of Quaternary Science, Volume 41, Issue 3, Page 419-432, April 2026.
ABSTRACT Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Hydrological Cycle Intensification and Permafrost Thaw Drive Increased Freshwater and Organic Carbon Inputs to Northern Alaska Estuaries

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Understanding how hydrological inflows and climate change influence individual estuaries across northern Alaska is limited by a paucity of measured data, necessitating the application of suitably scaled numerical process models. This study uses an updated model to quantify freshwater discharge and dissolved organic carbon (DOC) export from the

Remote sensing monitoring of fluorescent dissolved organic matter in Admiralty Bay: fusion of multi-source signal removal and machine learning

Science of Remote Sensing
Fluorescent dissolved organic matter (fDOM), a fluorescent component of dissolved organic matter (DOM), plays a crucial role in tracing pollution pathways in marine environments.
