 Two HABMAP survey cruises were carried out in summer 2005 on the RV Celtic Voyager.

The aim of the first cruise was to use multibeam swath bathymetry to collect information about the depth and nature of the seabed. Multibeam is an acoustic technique that sends a fan of sound signals down to the seabed and then analyses the way in which the sound bounces off the seabed and returns to the survey ship. This analysis gives us detailed data about depths (bathymetry) and also some information about the nature of the seabed (sediment types) by analysing backscatter. |

 Seabed video system The aim of the second cruise was to gather data about the biology and sediments of the areas surveyed in the first cruise. A sledge mounted video camera was used to take videos of the seabed. Grab samples were taken for information about sediments and biology. Sediment profiling imagery was also used to take pictures through sediments. |

In addition, some collaborative work was carried out in 2005 with the Joint Nature Conservation Committee and the MESH project in an area north of Anglesey.
A further cruise was carried out in September 2006 after Katrien Van Landeghem and Fionnuala McBreen were allocated five days of ship time on the Celtic Voyager from the Bright Sparks Competition. Two areas were surveyed, one towards the north of the HABMAP project area and another nearer the centre of the project area.
