Multibeam sonar survey covering Hythe Bay Marine Conservation Zone MCZ in 2012, Survey line spacing was designed to achieve 100% MBES coverage, thus lines were designed based upon 10m line spacing in 0-5m water depth, 20m line spacing 5-10m water depth and 30m line spacing for 15m water depth and 40m line spacing for 20m water depth and above. Survey cross lines were run at 20x mainline spacing. A minimum working depth of 3 metres of water was enforced on the survey vessel to maintain the safety of the vessel and crew. This survey approach allowed sufficient bathymetry soundings to be taken to meet the IHO Order 1a specification of the survey.

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Hythe Bay Marine Conservation Zone (MCZ) Survey Acoustic Data - 2012 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS218d5c78-ad05-4aa3-add0-c8dad259a24f |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20104 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
