Pan-Government Hydrographic Data

 

It is now easier to find out where Government multibeam data exists and where future surveys are planned.  Following the COSH meeting held in 2008, the MCA and DEFRA began negotiating a more formal agreement for cooperative working. Since then, both organisations have worked together to formulate a Memorandum of Understanding (MoU) covering bathymetric survey data and data gathering.  The principle aims of the MoU are:

  • To exchange existing and future multibeam echosounder data and backscatter data between participating organisations at no cost; and
  • To establish a mechanism to ensure that participating organisations’ future surveys are programmed in such a way so as to avoid duplication where ever possible.

The MoU represents a significant step in increasing offshore survey efficiency for Government organisations.  The MCA are extremely pleased to have partnered with DEFRA in developing the principles behind the agreement and in helping to author the document.  Signatories to the MoU include:
