An initiative known as the GIANT project, led by the British Antarctic Survey (BAS), aims to determine how a warming ocean is accelerating the melt of Greenland's tidewater glaciers, and what that means for global climate systems. This major climate science expedition is set to launch in the coming months, deploying a coordinated fleet of marine robots closer to Greenland's glaciers than ever before, with underwater positioning support provided by Sonardyne.

The UK's polar research vessel RRS Sir David Attenborough will deploy a networked system of autonomous aerial, surface and subsea vehicles into one of the planet's most challenging environments, gathering data at a scale and precision not previously achieved in this setting. Sonardyne’s Ranger 2 Ultra-Short BaseLine(USBL) positioning system onboard

An educational platform designed to make multibeam echosounder (MBES) surveying tangible for students, trainees and practising hydrographers has been released by the Department of Civil Engineering’s GPHIDRO Hydrographic Research Group at the Federal University of Viçosa (UFV) in Brazil. Conceived and developed by Professor Italo Ferreira, head of GPHIDRO, the MBES Simulator translates concepts that usually live inside operational software, technical standards and field experience into interactive three-dimensional scenes that anyone with a computer can explore.

The MBES Simulator platform addresses a recurring gap in hydrographic education. Acoustic survey geometry, swath coverage, ray bending in the water column, uncertainty propagation (TVU and THU) and platform attitude effects are often described in equations and norms before students ever see them happen. The
