BGDL-II: a GPS data logger for birds
Read more of: BGDL-II: a GPS data logger for birdsWe have developed a new GPS data logger consisting of a receiver, timer, memory, and battery. It is principally designed for long period tracking of migratory birds. It can fix […]

Late Quaternary terrigenous sediments from the Murray Canyons area, offshore South Australia and their implications for sea level change, palaeoclimate and palaeodrainage of the Murray-Darling Basin
Read more of: Late Quaternary terrigenous sediments from the Murray Canyons area, offshore South Australia and their implications for sea level change, palaeoclimate and palaeodrainage of the Murray-Darling BasinTwo sediment cores from the deep-sea Murray Canyons area, south of Kangaroo Island, Australia were investigated for quantity and composition of terrigenous material. Spanning the last 175 ka, terrigenous matter […]

A minimal substorm model that explains the observed statistical distribution of times between substorms
Read more of: A minimal substorm model that explains the observed statistical distribution of times between substormsA minimal model for the evolution of the global dynamical state of the magnetotail during the substorm has been developed, involving only three simple rules and one free parameter D-the […]

On the probability distributions of SuperDARN Doppler spectral width measurements inside and outside the cusp
Read more of: On the probability distributions of SuperDARN Doppler spectral width measurements inside and outside the cuspThe Doppler spectral width of backscatter from the SuperDARN HF radars has been routinely used to identify the ionospheric cusp. The probability distribution of spectral width values has been described […]

Protein synthesis, RNA concentrations, nitrogen excretion, and metabolism vary seasonally in the Antarctic holothurian Heterocucumis steineni (Ludwig, 1898)
Read more of: Protein synthesis, RNA concentrations, nitrogen excretion, and metabolism vary seasonally in the Antarctic holothurian Heterocucumis steineni (Ludwig, 1898)Seasonal changes in protein and nitrogen metabolism have not previously been reported in any Antarctic suspension-feeding species that ceases feeding for extended periods in winter. To provide comparison with data […]

A comparison of satellite and cruise chlorophyll-a measurements in the Scotia Sea, Antarctica
Read more of: A comparison of satellite and cruise chlorophyll-a measurements in the Scotia Sea, AntarcticaWe compared both SeaWiFS (Sea-viewing Wide Field-of-View Sensor) and MODIS (Moderate-resolution Imaging Spectroradiometer) chlorophyll-a (chl-a) measurements with simultaneous ship based data obtained during a 2003 British Antarctic Survey (BAS) research […]

Bottlenose dolphin abundance in the NW Mediterranean: addressing heterogeneity in distribution
Read more of: Bottlenose dolphin abundance in the NW Mediterranean: addressing heterogeneity in distributionLine-transect estimators were developed to assess abundance of coastal dolphins Tursiops truncatus and Stenella coeruleoalba encountered in low densities during aerial sighting surveys. The analysis improved on conventional approaches by […]

RADAR: the Cassini Titan radar mapper
Read more of: RADAR: the Cassini Titan radar mapperThe Cassini RADAR instrument is a multimode 13.8 GHz multiple-beam sensor that can operate as a synthetic-aperture radar (SAR) imager, altimeter, scatterometer, and radiometer. The principal objective of the RADAR […]

Tidal modulation of the gravity-wave momentum flux in the Antarctic mesosphere
Read more of: Tidal modulation of the gravity-wave momentum flux in the Antarctic mesosphereAirglow imager and dynasonde/IDI radar wind measurements at Halley Station, Antarctica (76degreesS, 27degreesW) have been used to estimate the diurnal variation of the vertical fluxes of horizontal momentum carried by […]

Seasonal variations of the gravity wave momentum flux in the Antarctic mesosphere and lower thermosphere
Read more of: Seasonal variations of the gravity wave momentum flux in the Antarctic mesosphere and lower thermosphereAirglow imager and dynasonde/imaging Doppler interferometer (IDI) radar wind measurements at Halley Station, Antarctica (75.6degreesS, 26.6degreesW) have been used to estimate the seasonal variation of the vertical fluxes of horizontal […]
