1.4 Research Objectives<br />

This <strong>the</strong>sis has three main objectives.<br />

Firstly, a seismic stratigraphic analysis <strong>of</strong> <strong>the</strong> Mesozoic <strong>and</strong> Cenozoic<br />

<strong>stratigraphy</strong>, definition <strong>of</strong> seismic sequences, tying <strong>the</strong>se sequences to available well data<br />

<strong>and</strong> publicly available information, <strong>and</strong> developing a framework for <strong>the</strong> description <strong>and</strong><br />

interpretation <strong>of</strong> <strong>the</strong> depositional <strong>history</strong> <strong>of</strong> <strong>the</strong> slope within <strong>the</strong> study area.<br />

Secondly, an analysis <strong>of</strong> <strong>the</strong> tectonic elements that deform pre-Mesozoic through<br />

Quaternary <strong>stratigraphy</strong>, with particular emphasis on <strong>the</strong> timing <strong>of</strong> tectonic deformation<br />

in relation to defined seismic <strong>stratigraphy</strong> packages, <strong>and</strong> <strong>the</strong> analysis <strong>of</strong> <strong>the</strong> related<br />

growth stratal architecture.<br />

A third objective <strong>of</strong> <strong>the</strong> research is an analysis <strong>of</strong> <strong>the</strong> salt tectonics with reference<br />

to <strong>the</strong> seismic <strong>stratigraphy</strong>, in order to provide a more integrated stratigraphic analysis <strong>of</strong><br />

<strong>the</strong> area. This provides a method for assessment <strong>of</strong> <strong>the</strong> importance <strong>of</strong> salt-sediment<br />

interactions across <strong>the</strong> study area.<br />

1.5 Data <strong>and</strong> Methods<br />

At <strong>the</strong> request <strong>of</strong> BP Canada, TGS-NOPEC <strong>of</strong> Houston, Texas, provided to me a<br />

digital data set <strong>of</strong> approximately 4 500 kilometers <strong>of</strong> high quality seismic data located<br />

over <strong>the</strong> central Scotian Slope (Figure 1-3). The data included a grid <strong>of</strong> forty 80-fold 2D<br />

seismic lines, each approximately 80-120 kilometers in length, with an average line<br />

spacing <strong>of</strong> approximately six kilometers. The seismic data is <strong>of</strong> 1998-99 vintage.<br />
