Other constraints

The dataset has been formally approved by BGS for access by external clients under a BGS Digital Data Licence, issued via BGS's IPR Section. The dataset must not be provided to, or be accessible by, an external client until the IPR Section confirms that signed licence documentation is in place. Refer to the IPR Section (DigitalLE@bgs.ac.) if further advice is required.

Statement

Single Beam acoustic survey data were collected in July 2013 and July 2014 over an area of ~15.5 km2 using a single-beam echo sounder (Ceeducer Ceestar 200 kHz), coupled with a Real-Time Kinematic Global Positioning System (RTK-GPS). Data were acquired along a suite of closely spaced (every ~100 m) north-south parallel lines across the location of known shoals (observed in Landsat imagery), and a series of ~500 m spaced shore-perpendicular lines to provide broader context for the shoals. Depth values were corrected for tidal variations throughout surveying in CarisTM HIPS and reduced to lowest astronomical tide (LAT) datum using tide gauge data at the Port of Townsville. Core data (sedimentology and palaeoecology),the cores from which the data were collected were recovered in July 2013 and July 2014. These data are based on the analysis of sediment samples recovered on a downcore basis (the depths from which each sample derive are listed in the attached Excel spreadsheet). This data was used as the basis for the following published study: Johnson JA, Perry CT, Smithers SG, Morgan KM, Johnson KG (2017, in press) Depth-controlled patterns in vertical coral community development within the turbid nearshore waters of the Great Barrier Reef: baselines for assessing ecological change. Coral Reefs Core radiocarbon dates, the cores from which the data were collected were recovered in July 2013 and July 2014. This data was used as the basis for the following published study: Morgan KM, Perry CT, Smithers SG, Johnson JA, Gulliver P (2016) Transitions in coral reef accretion rates linked to intrinsic ecological shifts on turbid-zone nearshore reefs. Geology 44: 995-998. Benthic video imagery, these images were collected in July 2013 and July 2014 using a hand-held frame-mounted underwater video camera (SeaViewer with Sea-Track™ GPS overlay). The camera was towed ~1 m above the seafloor along multiple 300 m transect lines. Still frames (~1 m2) were extracted from the video at automated 8 sec intervals (n = 4420) and a digital 9-point grid overlay was added.
