Benthic Habitat Survey Sites

Dataset Number1234
Dataset TitleBenthic Habitat Survey Sites
CustodianData Authority: Department for Environment and Water
Data Provider: Department for Environment and Water

Description

DescriptionPoint data collected from video drops identifying benthic habitats such as seagrass, macroalgae and reef, collected during field work in 2007 to 2011. Used to support the Benthic Habitat Mapping project undertaken by DENR to map the nearshore benthic habitats of South Australia.
UsageSurvey sites identify the biotic cover, substratum and seagrass genus (if present) in particular surveyed point locations around the state. The data can be used to support marine planning and management in SA.

Data Quality

LineageData was generated INTO a point layer using latitude and longitude coordinates collected on a non-differential GPS. Survey site data was collected to verify the broad scale 1:10,000 benthic mapping being undertaken by DENR in South Australia. Data was collected in 2007 - 2011 via GPS in WGS84 Datum and converted to GDA94 datum using ArcGIS 9.3.1
CompletenessDataset is complete to the information collected and supplied from the surveyor.
Positional AccuracyDue to a non-differential GPS being used point data will be accurate to approximately +/- 10 metres.
