Detailed topographic maps of the lunar poles have been obtained by Earth-based radar interferometry with the 3.5-centimeter wavelength Goldstone Solar System Radar. The interferometer provided maps 300 kilometers by 1000 kilometers of both polar regions at 150-meter spatial resolution and 50-meter height resolution. Using ray tracing, these digital elevation models were used to locate regions t...

BACKGROUND Concentrations of brominated flame retardants (BFRs) are reported to increase in marine ecosystems. OBJECTIVES Characterize exposure to BFRs in animals from different trophic levels in North-East Atlantic coastal marine ecosystems along a latitudinal gradient from southern Norway to Spitsbergen, Svalbard, in the Arctic. Calanoid species were collected from the Oslofjord (59 degrees...

Initial images of Venus's south pole by the Venus Express mission have shown the presence of a bright, highly variable vortex, similar to that at the planet's north pole. Using high-resolution infrared measurements of polar winds from the Venus Express Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) instrument, we show the vortex to have a constantly varying internal structure, with ...

The spatial-temporal dynamics of forest fires for last five years in latitudinal range 40-74 degrees of the northern latitude are analyzed with using the data of the radiometer AVHRR/NOAA. It was shown that forest fires are observed from May till September, basically during three summer months with a maximum of the activity during the second half of summer. On a phase of a maximum of an 11-year...

Dynamic climatic oscillations of the Pleistocene dramatically changed the distributions of high latitude species. Molecular investigations of a variety of organisms show that processes of postglacial colonization of boreal regions were more complex than initially thought. Phylogeographical and coalescent analyses were conducted on partial sequences of the cytochrome b gene (600 bp) from 64 indi...

tehran is located in a valley at the foot of the alborz mountains in northern iran (35 degrees latitude north). urban expansion in tehran resulted from a high rate of population growth and rural-urban migration combined with a strong tradition of centralization in the capital. airborne particulate of tehran's atmosphere was fractionated in a 6-stage high-volume cascade impactor. the first ...

The quest for detecting dark-matter subhalos within the Galactic halo has taken many forms. Particularly interesting and promising is use of spectral degeneracies to distinguish otherwise indistinguishable gamma-ray sources with near-null star formation. In further exploration this realm, we attempt classify high-latitude, non-variable, unassociated Pulsar-like spectra in 20-70 GeV Dark Matter ...
