Focus on what matters to you when reviewing a spec sheet

Knowledge & Training

Multibeam echosounders are defined by technical features that are specific to acoustic devices. Some of the technical terms may not initially be intuitive even to surveyors.

The objective of this document is to define each technical term to help you understand the importance and implication of each of those concepts in the context of a hydrographic survey.

University of Malta Survey Project

We are delighted to participate in this project supported by the Maltese National Space Fund and the European Space Agency, to survey the coastline of the Maltese Island to test the viability of a workflow for obtaining a new bathymetric layer from satellite derived information.

Tips for surveying over soft & muddy bottoms

Many surveys are in areas that are less than ideal for acoustics.  These types of areas have seafloors that are soft and comprised mostly of mud as opposed to sand or gravel. The multibeam transmitter emits an acoustic pulse that reflects mostly off of the bottom and back to the…

MultiSpectral versus Multifrequency Backscatter: A Generational Advancement

Multibeam Backscatter is a tool used in seafloor characterization, and R2Sonic‘s recent MultiSpectral Backscatter advancement dramatically improves this process.  MultiSpectral Backscatter comprises two or more frequencies collected in one-pass using an advanced sonar capable of multifrequency transmissions, either interleaved or simultaneous. MultiSpectral Backscatter should not be confused with MultiFrequency Backscatter Older sonars can collect Multifrequency Backscatter…
