Abstract

A marine survey node can include a body to be deployed to a seabed, a marine survey receiver coupled to the body and to acquire marine survey data, and a soil sample module associated with the body to collect a soil sample from the seabed. A soil sample module can include a vessel, a first valve coupled to the vessel, and a spike coupled to the vessel. The spike can penetrate an earth surface. The first valve can maintain a pressure difference between the vessel and the spike when closed and equalize a pressure between the vessel and the spike when open. An inlet in the spike can equalize pressure between an inside of the spike and an outside of the spike and to collect a soil sample from the earth surface.
