Stema Systems supplies hydrography and oceanology related measurement systems. Besides the development, design and manufacturing of products, Stema Systems integrates sensors, systems and software based upon customer requirements. We are the geophysical subbottom  & fluidmud company.

Based in the Netherlands, a country that lives, works and is even built in the sea, we have an intense interaction with the marine environment. The question is not whether there is a need for gaining knowledge about coastal status and processes for national safety, economy and environmental purposes. The question is how to obtain the best quality and complete datasets in a cost efficient way. For more than 30 years we participate in this process and we may state this way of thinking and doing has grown into the genes of our company. We operate global for numerous companies such as harbors, research institutes, universities, dredging companies, surveying companies, etc.
