Plankton, a diverse group of aquatic organisms, make Earth livable, regulate aquatic life, and provide benefits to human societies such as access to clean water, food security, and well-being. They also support economies and inspire biotechnological innovations.
The Southern Ocean Time Series (SOTS) provides highly temporally resolved observations of the physical, chemical, and biological variability in the upper ocean, as well as the export of particulate organic and inorganic carbon to the ocean interior, in the subantarctic region south of Australia.
On January 15, 2022, an ongoing eruption at the Hunga-Tonga Hunga-Ha'apai volcano generated a large explosion which resulted in a globally observed tsunami and atmospheric pressure wave.
We report the first observations of simultaneous high?]latitude interhemispheric F region … neutral wind fields by combining the 630 nm optical measurements from two scanning … Doppler imagers (SDIs) and three Fabry?]Perot interferometers (FPIs) for a period … exceeding 5 h.
We report the first observations of simultaneous high-latitude inter-hemispheric F-region neutral wind fields by combining the 630 nm optical measurements from two scanning Doppler imagers and three Fabry-Perot interferometers for a period exceeding 5 hours on 3 October 2008.
La Trobe University has recently installed a new all-sky imaging Fabry-Perot spectrometer at Mawson Station, Antarctica. It is capable of recording independent spectra from many tens of locations across the sky simultaneously…
All-sky imaging Fabry-Perot spectrometers can provide two dimensional maps of thermospheric wind and temperature fields over a circular region spanning around 1400 km in diameter at F-region heights, or about half this in the E-region.
A new Scanning Doppler Imager (SDI) has been constructed and recently located to Mawson, Antarctica. The SDI is a separation scanning Fabry-Perot Interferometer (FPI) coupled to an all-sky lens and imaging detector. This permits rapid scanning of the interference fringes over most of the sky.
Large-etalon Fabry-Perot Spectrometers (FPS) measure upper atmosphere winds and temperatures by observing spectral profiles of atmospheric emission lines with sufficient resolution to determine the Doppler broadening, from which temperature is deduced…
The major phospholipids of Halorubrum lacusprofundi grown at 25 1C were archaeol phosphatidylglycerol, archaeol … phosphatidylglycerylsulphate and archaeol phosphatidylglycerylphosphate methyl ester.Glycolipids included a monoglycosyl archaeol and the sulphate ester of a diglycosyl archaeol.
