SCIENTIFIC/TECHNICAL OBJECTIVES Modeling objectives are: (1) to produce a new generation of basin-scale ocean circulation models based on the spectral nite element technique; (2) to compare the performance of the resulting nite element model with that of more traditional ocean circulation models; (3) to couple the resulting basin-scale model to sub-basin-scale models for (e.g.) the coastal boun...

Understanding the water balance of large groundwater systems is fundamental for the sustainable management of the resource. However, measuring many of the major components of the water balance pose considerable challenges and are thus estimated through modelling. A shortcoming of the modelling approach is that the water balance may have high bias and uncertainty due to insufficient information....

We investigate the evolutionary history of the wide-ranging Nearctic treefrog Hyla arenicolor through the integration of extensive range-wide sampling, phylogenetic analyses of multilocus genetic data, and divergence dating. Previous phylogeographic studies of this frog documented a potential signature of introgressive hybridization from an ecologically and morphologically divergent sister spec...

The linear and nonlinear Rossby wave solutions are examined in homogeneous square basins on the /-plane both with and without a thin meridional barrier. In the presence of the meridional barrier the basin is almost partitioned into two; only two small gaps of equal width, d, to the north and south of the barrier allow communication between the eastern and western sub-basins. Solutions are force...

Scarcity of in-situ observations coupled with high orographic influences has prevented a comprehensive assessment of precipitation distribution in the high-altitude catchments of Indus basin. Available data are generally fragmented and scattered with different organizations and mostly cover the valleys. Here, we combine most of the available station data with the indirect precipitation estimate...

A multidisciplinary study involving lithofacies analysis, palynofacies, and palynology is presented for the Muarádzi Sub-basin. This sub-basin part of Moatize-Minjova Basin (MMB), an important Karoo aged coalfield in Mozambique. total 99 core samples from 3 coal exploration boreholes (DW11, DW21, DW141) were analysed all successions assigned a Lopingian age based on palynology. According to dat...
