New observations and progresses in Marine Geosciences are highly dependent on technology. During oceanographic expeditions onboard research vessels, seagoing geologists can use various material to collect seafloor data. 

In this pages are presented some of the most well-known research vessel, as well as a set of instruments and technics that are used during scientific exploration of the seafloor.
