The results of the geophysical survey were used to identify potential Annex I habitats and also to inform the benthic habitat survey sampling locations. Without the presence of ground truth information preliminary seabed features interpretation was based on the acoustic reflectivity and texture of the side-scan sonar data. Following the results of the benthic habitat survey carried out in September – October 2010 the interpreted seabed features were re-classified to characterise the actual nature of seafloor sediments.

Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08T00:00:00 publication Conformity with the Commission Regulation (EU) No 1089/2010 was either not relevant to this dataset or not a requirement of the Marine Data Exchange for the creation and submission of this dataset; therefore, conformity has not been assessed and cannot be declared False series All bathymetric data in this report was reduced to Chart Datum Skegness. Figure 4 illustrates the relationships between the vertical datum and the tidal levels. Where elevation data have been measured and recorded relative to Ordnance Datum (Newlyn) an offset to Chart Datum Skegness has been applied, using the British Admiralty published value for Skegness of -3.75m (NP201 ATT Vol1). A seabed mounted tide gauge was used in conjunction with the RTK GPS data collected on both vessels for the tidal reduction. An Aanderaa WLR7 tide gauge was deployed after arrival on site on the 19th July at 328773E, 5884043N. The Aanderaa tide gauge is self-contained water level recorder and was set to store a pressure record every 5 minutes, with a sampling period of 40 seconds each time to minimise the effect of the waves. The tide gauge was recovered on the 1st August for intermediate data retrieval and redeployed the same day at 328798E, 5884057N. The tide gauge was again recovered after the completion of all the survey operations on 4th August and full data recovery as obtained. Benthic samples were acquired using a 0.1m2 Hamon grab. A total of 111 samples were obtained, triplicate samples were acquired at 18 locations (56 samples) and a further 55 single samples were acquired elsewhere within the Lincs survey area.
