Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

The Cruise of the Antarctic to the South Polar Regions

open access: yes, 1896
The Norwegian businessman, shipping magnate and whaling entrepreneur Henrik Johan Bull (1844–1930) led the first expedition to make a confirmed landing on the Antarctic mainland, at Cape Adare, in January 1895. Bull's highly readable account of the expedition, published in 1896, reveals both the scientific and the commercial motivations for early ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Pseudorchomene boreoplebs, a new lysianassid amphipod from Korean waters (Crustacea, Amphipda, Lysianassoidea)

open access: yesZoosystematics and Evolution, 2017
Until now, the genus Pseudorchomene Schellenberg, 1926 has been recorded exclusively in Antarctic or sub-Antarctic regions. Pseudorchomene boreoplebs sp.

Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

ICESat-2 Crossover-Constrained refinement of the Copernicus 30 m DEM in selected Antarctic regions using Machine learning

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Accurate and spatially consistent digital elevation models (DEMs) remain challenging to obtain in Antarctic environments. This study develops and evaluates an ICESat-2 crossover-constrained machine-learning framework for refining the Copernicus 30 m ...

Transposons as Tools for Future Genome Engineering in Yeasts and Filamentous Fungi

open access: yesYeast, EarlyView.
Applications of transposon‐based tools for genome engineering in fungi include transposon‐mediated mutagenesis and targeted genomic integration. ABSTRACT Transposons are fundamental genetic elements that have profoundly shaped the architecture of eukaryotic genomes.

Humble beginnings of the Australian giant wood moth (Endoxyla cinereus): A century‐old mystery solved

open access: yesInsect Science, EarlyView.
The Australian giant wood moth (Endoxyla cinereus) feeds within the galls of scale insects (Apiomorpha) before transitioning into its wood‐boring eucalypt larval phase. This transitionary phase may be key to its multi‐year development, at the end of which it can produce over 100 000 eggs.
