"Finding Nemo!"

We were collecting resistivity data last summer in the northern part of Texas. After each roll-along section, I was inverting the data to check the data quality as well as the potential anomalies for which we were looking. During one of these moments, I heard my geotech, who was watching the inversion process over my shoulder, say jokingly: Hey Doc, I think we found the Nemo! He was referring to the computer-animated movie “Finding Nemo.” It was about a clownfish’s adventure in the sea and on the land due to his overprotective father!! Yes the anomaly, which is shown with the blue color below, depicted a “fish” anomaly; but this was a giant “fish” anomaly with a big tail, not a small clownfish!

To be more serious, we had conductivity and magnetic anomalies over the “fish” anomaly as well. Furthermore, excavation and soil sampling results indicated that the anomaly was caused by two pipes crossed each other at a depth of 4 feet, and the contaminated soil affected by the leakage from these pipes.
