Geophysical seismic surveys and port security may appear to have little in-common. However, it turns out that managing complex marine seismic operations, where 10km-long seismic streamers have to be deployed harmoniously alongside other offshore marine assets, isn’t that dissimilar to managing – and protecting – port facilities.It's an area that ION Geophysical, more known for seismic data acquisition technology, has recently been proving its expertise in, using its Marlin system for marine operations management.
