Hydrographic survey collecting acoustic data. Data collected and interpreted by in-house experts. Interpretation included the production of a seabed features chart for the area.

This field gives an indication of whether some data quality control has been carried out: 3 = remote data collected to approved standards 2 = remote data collected to ?internal? standards 1 = no standards applied to the collection of the remote data RemoteVintage An indication of the age of the remote data: 3 = < 5yrs old. 2 = 5 to 10 yrs old. 1 = > 10 years old BGTTechnique An assessment of whether the ground-truthing techniques used to produce this map were appropriate to the environment they were used to survey. Use scores for soft or hard substrata as appropriate to the area surveyed. Soft substrata predominate (i.e. those having infauna and epifauna) 3 = infauna AND epifauna sampled AND observed (video/stills, direct human observation) 2= infauna AND epifauna sampled, but NOT observed (video/stills, direct human observation) 1 = infauna OR epifauna sampled, but not both. No observation. Hard substrata predominate (i.e. those with no infauna) 3 = sampling included direct human observation (shore survey or diver survey) 2 = sampling included video or stills but NO direct human observation 1 = benthic sampling only (e.g. grabs, trawls) PGTTechnique An assessment of whether the combination of geophysical sampling techniques were appropriate to the environment they were used to survey. Use scores for soft or hard substrata as appropriate to the area surveyed. Soft substrata predominate (i.e. gravel, sand, mud) 3 = full geophysical analysis (i.e. granulometry and/or geophysical testing (penetrometry, shear strenght etc)) 2 = sediments described following visual inspection of grab or core samples (e.g. slightly shelly, muddy sand) 1 = sediments described on the basis of remote observation (by camera). Hard substrata predominate (i.e. rock outcrops, boulders, cobbles) 3 = sampling included in-situ, direct human observation (shore survey or diver survey) 2 = sampling included video or photographic observation, but NO in-situ, direct human observation 1 = samples obtained only by rock dredge (or similar) GTPositioning An indication of the positioning method used for the ground-truth data: 3 = differential GPS 2 = GPS (not differential) or other non-satellite 'electronic' navigation system 1 = chart based navigation, or dead-reckoning GTDensity An assessment of what proportion of the polygons or classes (groups of polygons with the same ?habitat? attribute) actually contain ground-truth data: 3 = Every class in the map classification was sampled at least 3 times 2 = Every class in the map classification was sampled 1 = Not all classes in the map classification were sampled (some classes have no ground-truth data) GTStdsApplied An assessment of whether standards have been applied to the collection of the ground-truth data. This field gives an indication of whether some data quality control has been carried out: 3 = ground-truth samples collected to approved standards 2 = ground-truth samples collected to 'internal' standards 1 = no standards applied to the collection of ground-truth samples GTVintage An indication of the age of the ground-truth data: 3 = < 5 yrs old 2 = 5 to 10 yrs old 1 = > 10 years old GTInterpretation An indication of the confidence in the biological interpretation of the ground-truthing data: 3 = Evidence of expert interpretation; full descriptions and taxon list provided for each habitat class 2 = Evidence of expert interpretation, but no detailed description or taxon list supplied for each habitat class 1 = No evidence of expert interpretation; limited descriptions available RemoteInterpretation An indication of the confidence in the interpretation of the remotely sensed data: 3 = Appropriate technique used and documentation provided 2 = Appropriate technique used but no documentation provided 1 = Inappropriate technique used Note that interpretation techniques can range from ?by eye? digitising of side scan by experts to statistical classification techniques. DetailLevel The level of detail to which the 'habitat' classes in the map have been classified: 3 = Classes defined on the basis of detailed biological analysis 2 = Classes defined on the basis of major characterising species or lifeforms 1 = Classes defined on the basis of physical information, or broad biological zones MapAccuracy A test of the accuracy of the map: 3 = high accuracy, proven by external accuracy assessment 2 = high accuracy, proven by internal accuracy assessment 1 = low accuracy, proved by either external or internal assessment OR no accuracy assessment made Remote GT Interpretation Survey technique(s): Multibeam echo sounder ; Single beam echo sounder ; Side scan sonar Classification scheme: Substrate only Classification scheme details: Seabed features description Survey technique details: Resolution of data : Swath & Side Scan <1m; Single Beam <100m between survey lines; Spatial Accuracy to within 10m Emu Ltd Emu Ltd Mapping method: Expert judgement; Mapped directly
