The geophysical data acquisition programme was carried out by M.V. Ivero, which sailed from Barrow and returned to there upon completion of survey operations. Titan Environmental Surveys Ltd were commissioned by Gardline Geosurvey to undertake the shallow water cable landfall survey, between 27-Dec-2012 and 26-Jan-2013. The survey objectives were: A) Hydrographical: To provide high quality data for interpretation of: 1. Accurate bathymetry with high resolution and low noise 2. Geomorphologic features on the seabed Geophysical: B) To provide high quality data for interpretation of: 1) Any objects at or below seabed that can influence possible offshore installations 2) Information on possible ferromagnetic objects in the area 3) Information on possible archaeological features in the area 4) Identification of geological layers There will be no limitations when published on the Marine Data Exchange otherRestrictions Data Must be used in accordance to the Marine Data Exchange's Terms of Use: https://www.marinedataexchange.co.uk/content/info/terms-of-use otherRestrictions The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk custodian Gardline Geosurvey Limited +44 (0)1493 845 600 geosurvey@gardline.com originator The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk distributor Orsted info@orsted.com owner notPlanned Delimited Documents Geographic Information System Text or Plaintext https://www.marinedataexchange.co.uk/details/TCE-2214/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.

These figures were processed and presented in tabulated form to enable positional verification. Sigma figures are generated for the axes of Sigma North, Sigma East and Sigma Up. Each individual sigma display was a probability estimate of how close actual position was to the GPS displayed position. Given the sigma values for a position fix, it was possible to construct an error ellipse; this was a graphical representation of the position fix, which displayed the indicated GPS position at the centre of the ellipse with the relevant sigma error ellipse centred on this position (Figure 5.1). The 1-sigma error ellipse represented the probability that a position fix was within 68% of the indicated position and the two-sigma error ellipse represented the chance of a position fix being within 86.4% of the indicated position.
