【 摘 要 】

In March, 1999, a combined geophysical field team from the Kansas Geological Survey, Oak Ridge National Laboratory, and the Geological Survey of Canada, performed some experimental high resolution seismic testing at the Mallik drill site in the Mackenzie Delta, Northwest Territories, where drilling and sampling had previously identified gas hydrates at depth beneath a thick permafrost zone. In this information document, we show data from this seismic test, along with comparisons and observations significant to the effective use of high resolution imaging and important considerations about high resolution operations in this environment. Included are discussions and examples based on previous studies at this site, data acquisition, processing, correlation of results with other data sets and some recommendations for future surveying.
