L-band (3.5 um) IR-excess in massive star formation. II: RCW 57/NGC 3576 Astronomy & Astrophysics, 2006 (Ref: 12857)
Category 1: Peer-reviewed literature

We present colour-colour and colour-magnitude diagrams for RCW 57 (NGC … 3576) based on L-band data at 3.5 ìm taken with SPIREX (South Pole Infrared Explorer), and 2MASS JHKs data at 1.25-2.2 ìm. A total of 251 sources were detected.

Why do we need "DigiDARN" - a global network of digital SuperDARN radars? Proceedings of the Workshop on the Applications of Radio Science, Refereed Paper R-25, Leura, New South Wales, 15-17 February, 2006, 2006 (Ref: 13075)
Category 1: Peer-reviewed literature

The Super Dual Auroral Radar Network (SuperDARN) is an international network of oblique HF over-the-horizon … radars dedicated to the study of high latitude magnetosphere-ionosphere convection. In scientific terms, they have been … an outstanding success…

In situ measurements of the direct-current conductivity of Antarctic sea ice: implications for airborne electromagnetic sounding of sea-ice thickness Annals of Glaciology, 2006 (Ref: 12847)
Category 1: Peer-reviewed literature

Airborne, ship-borne and surface low-frequency electromagnetic (EM) methods have … become widely applied to measure sea-ice thickness. EM responses measured over sea ice depend … mainly on the sea-water conductivity and on the height of the sensor above the sea-ice–sea-water … interface…

Seasonal changes in bacterial biomass and activity at an Antarctic coastal site SCAR XXIX/COMNAP XVIII Conference 8-15 July 2006. Hobart, Australia, 2006 (Ref: 12998)
Category 3: Poster

Bacteria play a key role in the world's oceans, supporting nutrient remineratlisation and mediating … carbon transfer. Most studies of marine bacteria in the … Southern Ocean are restricted to the summer months. Thus…

Nematodes from saline and freshwater lakes of the Vestfold Hills, East Antarctica, including the description of Hypodontolaimus antarcticus sp. n. Polar Biology, 2006 (Ref: 12797)
Category 1: Peer-reviewed literature

The invertebrate fauna of many Antarctic … ice-free areas, even those close to permanent research … stations, can be poorly known. Here we describe some … nematodes from freshwater and saline, marine-derived … lakes of the Vestfold Hills, East Antarctica.

Estimation of thin sea-ice thickness from NOAA AVHRR data in a polynya off the Wilkes Land coast, East Antarctica Annals of Glaciology, 2006 (Ref: 12848)
Category 1: Peer-reviewed literature

Antarctic coastal polynyas are major areas of intense ocean–atmosphere heat and moisture … flux, and associated high sea-ice production and dense-water formation. Their accurate detection, including an estimate of thin ice thickness, is therefore very important. In this paper…

Validation of AVHRR and MODIS ice surface temperature products using in situ radiometers Annals of Glaciology, 2006 (Ref: 12846)
Category 1: Peer-reviewed literature

Ship-borne and airborne infrared radiometric measurements during the ARISE cruise of September–October 2003 permitted in situ validation studies of two satellite-based ice surface skin temperature algorithms:
