Extreme-ultraviolet images taken by the Atmospheric Imaging Assembly make it possible to use deep vision techniques in the prediction of solar wind speed - a difficult, high-impact, and unsolved problem.…6 July, 2021 by Joseph Ulanowski
Numerous studies of the electrical properties in dusty environments, related to lofted particle charging, indicate that it is a rather complex mechanism which greatly affects the particle dynamics. The electrification…14 July, 2020 by Mark Clilverd
“ACHDANet” (Automatic Chorus and Hiss Detector and Analyzer Network) project is an analogy to, and additional product of the well-known AWDANet. Our mission is to create a monitoring system which…14 July, 2020 by Richard Horne
Van Allen Probes EMFISIS observations in both survey and burst mode are coupled with ray tracing simulations to determine the percentage of chorus wave power that exists with the conditions…3 May, 2020 by Alex Brisbourne, Andy Smith, Carlos Martin Garcia
Lateral shear margins provide resistance to ice flow within ice streams and play an important role in the overall dynamics of ice sheets. The strength and location of shear margins…20 January, 2020 by Alexander Brearley
A Kongsberg Seaglider with a microstructure package was deployed in the Faroe-Shetland Channel in 2017 as part of the 4th Marine Autonomous Systems in Support of Marine Observations (MASSMO4). Using…1 December, 2019 by Dani Jones
Abstract—We use an unsupervised classification technique (i.e. Gaussian mixture modeling or GMM) to identify ocean regions with similar balances between processes that determine the surface budget of dissolved inorganic carbon.…Read more on Gaussian mixture modeling describes the geography of the surface ocean carbon budget.

Competing multi-sectorial water demands as well as demands for ecosystem services in coastal aquifers exert significant pressures to local water resources. Climate change is already altering spatiotemporal rainfall and runoff…6 June, 2019 by Jeremy Wilkinson
To support future scientific missions beneath Antarctic ice shelves, the Antarctic Gateway Partnership, a special research initiative of the Australian Research Council, is trialling its Autonomous Underwater Vehicle, nupiri muka,…1 July, 2015
Antarctic crews have been transporting plants and their supporting infrastructure to Antarctic field sites since as early as 1902. More than 46 distinct plant production facilities have, at one time…1 January, 2014 by Dominic Hodgson, Peter Convey
The Antarctic Peninsula is one of the most rapidly warming regions on Earth, with air temperature increases of as much as 3°C recorded since the 1950s. However, the longer-term context…11 April, 2013 by Damien Guihen, Eugene Murphy, Sophie Fielding
The GENTOO project aims to investigate the potential for undersea gliders to make high resolution temporal and spatial biological and physical observations of ocean currents and krill distribution to the…Read more on Acoustic detection of krill from an undersea glider
