How to Get the Most Out of U-Net for Glacier Calving Front Segmentation
, 2023 The melting of ice sheets and glaciers is one of the main contributors to global sea-level rise. Hence, continuous monitoring of glacier changes and in particular the mapping of positional changes of their calving front is of significant importance. This

Glacier inventory and recent glacier variations in the Andes of Chile, South America
Annals of Glaciology, 2017 The first satellite-derived inventory of glaciers and rock glaciers in Chile, created from Landsat TM/ETM+ images spanning between 2000 and 2003 using a semi-automated procedure, is presented in a single standardized format.

AutoTerm: A "big data" repository of Greenland glacier termini delineated using deep learning
, 2022 Abstract. Ice sheet marine margins via outlet glaciers are susceptible to climate change and are expected to respond through retreat, steepening, and acceleration, although with significant spatial heterogeneity. However, research on ice-ocean interactions has continued to rely on decentralized, manual mapping of features at the ice-ocean interface ...

Journal of Glaciology, 2019 Over recent decades, the number of outlet glaciers terminating in lakes in Iceland has increased in line with climate warming. The mass-balance changes of these lake-terminating outlet glaciers are sensitive to rising air temperatures, due to altered ...

Deriving a year 2000 glacier inventory for New Zealand from the existing 2016 inventory
Annals of Glaciology, 2023 Due to adverse snow and cloud conditions, only a few inventories are available for the maritime glaciers in New Zealand. These are difficult to compare as different approaches and baseline data have been used to create them.

Geografia Fisica e Dinamica Quaternaria, 2023 Glaciers are vital freshwater reservoirs on Earth, and Pakistan is home to some of the world's largest mid-latitude glaciers, which greatly contribute to the country's economy. The accelerated melting of glaciers worldwide due to climate change underscores the significance of regular monitoring.

Remote Sensing, 2022 Mapping the outlines of glaciers has primarily relied on the interpretation of satellite optical images. However, the accurate delineation of glaciers in complex terrain mountain regions remains challenging, mainly because the supraglacial debris-covered

Glacier Front Dynamics of Antarctica - Analysing Changes in Glacier and Ice Shelf Front Position based on SAR Time Series [PDF]
, 2020 The Antarctic ice sheet stores ~91% of the global ice volume which is equivalent to a sea-level rise of 58.3 meters. Recent disintegration events of ice shelves and retreating glaciers along the Antarctic Peninsula and West Antarctica indicate the ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
