Originators of Glacial Theories

Theories and Modeling of Glacial–Interglacial Cycles and Glacial Inception

Broadcasting from multiple originators

We begin an investigation of broadcasting from multiple originators, a variant of broadcasting in which any k vertices may be the originators of a message in a network of n vertices. The requirement is that the message be distributed to all n vertices in minimum time. A minimum k-originator broadcast graph is a graph on n vertices with the fewest edges such that any subset of k vertices can bro...

Persistence of Gulf Stream separation during the Last Glacial Period: Implications for current separation theories

[1] We present stable oxygen isotope ratio (dO) measurements on deep-dwelling planktonic foraminifera from thewesternmargin of the North Atlantic in order to reconstruct the latitude at which the Gulf Stream separated from the western boundary of the Atlantic Ocean in the past. The modern separation latitude can be reconstructed within one degree from dO measured on the fossil shells of deep-dw...

study of glacial valley landform case study: sahand glacial valleys

abstract a mountain glacier, when it occupies a river valley, immediately begins to change the cross-section and profile of that valley. river valleys in mountain areas tends to have v-shaped profiles. glaciers work to widen as well as deepen their valleys and the typical cross-section of a glacial valley is u-shaped. the u-shaped glacial valley is one of the most characteristic of glacial land...

Morphometric Properties of Glacial Cirques in Zagros Mountain, IRAN

The morphometry of 187 cirques like forms is performed in the selected regions of Zagros Mountain with the use of GIS. The cirques like forms were delimitated manually and their headwall and floor boundaries were modified based on the classified slope map. The power law functions were fitted to 187 longitudinal cross-sections of the cirque like forms and their parameters were analyzed. All the ...
