Seaguard RCM

The single-point SEAGUARD® RCM series is a completely new generation of current meters based on the SEAGUARD® datalogger platform and the ZPulse® multi-frequency Doppler Current Sensor (DCS). SEAGUARD® Products are based on modern technology and are the basic modules of our underwater observatory. They may be used as a multi-parameter instrument in the sea and in freshwater and feature a modular plug-and-play architecture.

2016,May - Below the surface in ports: topography, navigation and pollution

Increasing ship size and higher demands for more efficient ports have increased the responsibilities for port and navigational authorities. This application oriented webinar will show how solutions from Aanderaa, HYPACK and SonTek help one harbour deal with increasing demands:

  • HydroSurveyor M9 compact high performance systems to measure bathymetry and currents in ports and harbors
  • CastAway CTD offers seamless integration of sound speed information
  • HYPACK software powerful tool to plan missions and analyze data
  • HydroSurveyor M9, CastAway and HYPACK - a complete survey package from Xylem
  • Aanderaa have offered turn key hydro-meteorological soltuions for ports and harbors globally
  • Side looking insturments suitable for pier mounting
  • New buoys combine single point and profiling Doppler current sensors to cover the entire water column
  • Mulitparameter insturuments like SeaGuard RCM and SeaGuard II DCP are suitable for lead detection and pollution spreading studies from wrecks
