East Antarctica magnetically linked to its ancient neighbours in Gondwana

East Gondwana ancestry of the sunflower alliance of families.

The sunflower alliance of families comprises nearly 10% of all flowering plant species and includes the largest of all plant families, the sunflower family Asteraceae, which has 23,000 species, and the bellflower family Campanulaceae. Both are worldwide in distribution, but the majority of their species occur in the northern hemisphere. Recently it has been shown that a number of small, woody f...

Deep Seismic Exploration of East Gondwana: A Proposal (LEGENDS)

Systematic exploration of the continental lithosphere by deep seismic reflection profiling over the past 20 years has revolutionized our view of the deep crust and upper mantle. Major geological features have been traced to lower crustal depths. Certain deep crustal features have been traced into the underlying mantle (fossil subduction zones?). Some geotectonic boundaries, considered by genera...

Trade Reforms in India Ten Years On: How Has It Fared Compared to Its East Asian Neighbours?

Flow dynamics of Byrd Glacier, East Antarctica

Force-balance calculations on Byrd Glacier, East Antarctica, reveal large spatial variations in the along-flow component of driving stress with corresponding sticky spots that are stationary over time. On the large scale, flow resistance is partitioned between basal (�80%) and lateral (�20%) drag. Ice flow is due mostly to basal sliding and concentrated vertical shear in the basal ice layers, i...

Wood Use in the Ancient Near East

Wood. Forests were exploited from the very beginnings of Near Eastern civilization. Enough hints exist from such Aceramic Neolithic sites as Jericho in Israel and Çayönü, Asikli Höyük, Nevali Çori, and Hallan Çemi in Turkey to indicate that extensive forest use has a history in this region of at least ten thousand years. These sites provide ample burned evidence for architectural timbers used a...
