For underwater gliders (UGs), high trajectory accuracy is an important factor in improving the observation of ocean phenomena. In this paper, a novel method optimization proposed to increase UGs, which approximately based on nonlinear dynamic model, rather than linearization model. Firstly, model UGs established analyze effect input parameters error, some approximate models that replaced due it...

The Diomedeoididae are an extinct group of the Procellariiformes (tubenoses), which appears to have been widespread in the epicontinental seas covering parts of Europe in the Oligocene. A fair number of skeletons and isolated bones of these birds are known from Oligocene and early Miocene sediments of Central Europe (Cheneval 1995; Mayr et al. 2002; Fischer 2003). A record from early Oligocene ...

This study focuses on the structural picture interpretation of Buzurgan oil field in Maysan province southern Iraq. Using 2D seismic data, Synthetic traces are created by selecting reflectors section using Petrel software and well (BU-1) data currently available. The represented Paleocene to middle Miocene, which L-Fars-Kirkuk-Jaddala-Aaliji. A thrust fault that solely impacts L-Fars formation ...

Procellariiform seabirds (the petrels, albatrosses and shearwaters) are recognized for their acute sense of smell. These pelagic seabirds forage over thousands of miles of ocean to find patchily distributed prey resources. Over the past decade, much headway has been made in unravelling the variety of olfactory foraging strategies that Antarctic species employ, and it is becoming clearer that ol...
