| ASI provides a complete range of marine geophysical, hydrographic and visual inspection techniques to conduct underwater mapping investigations. Submerged surface features and targets are located, measured and mapped with precision accuracy in real-time using a combination of geophysical mapping and charting technology. In-house cartographers and graphic specialists produce quality technical reports (hardcopy and GIS compatible formats) utilizing geophysical data. |

ASI's survey vessels are trailerable and equipped with a wide variety of survey equipment packages. In addition to surface vessels, ASI owns and operates a fleet of purpose-built remotely operated vehicles (ROV's) to deploy sonar and video imaging in open water, tunnels and pipelines. |
Technical advances in marine geophysical survey instrumentation and methodologies provide greater efficiency and accuracy in underwater mapping of rivers, estuaries, channels, lakes or harbor bottom surfaces. |
