Echo Sounders versus Air Bubbles in Research Vessels
Within echo sounding circles it is well known that air bubbles may have a negative effect on echo sounding systems. This article briefly presents the German way of dealing with air...
Surveying in the Arctic has its particular challenges however it’s important looking at aspects as increased shipping, environmental research, significance for oil & gas, together with the challenging circumstances to work. However, for surveying and navigating Hydro International has collected content throughout the years.
