Four core samples were collected from various locations on the reef and radiometerically dated. This allowed sedimentation rates for the Holocene sediments of Wistari Reef to be calculated. The maximum sedimentation rate represents the accumulation that has occurred between the core top date and the core base date; the minimum accretion rate takes only the basal core data into account, thus allowing for bioturbation of the sediments. The biggest maximum rate of accretion was seen at core IC-02, which exhibited an accretion rate of 4.79m/ka. The smallest minimum accretion rate was seen in VC-02 (on a sanded reef flat) with a accretion rate of 0.57m/ka. {"type": "Polygon", "coordinates": [[[151.5, -24.5], [153.0, -24.5], [153.0, -23.0], [151.5, -23.0], [151.5, -24.5]]]} 151.5 153.0 -24.5 -23.0 Oceans | Coastal Processes | Coral Reefs Oceans | Marine Sediments | Sedimentation accretion_rate latitude longitude ANU_Ryan_Cores_2_data.xls documentDigital XLS aodn:sediment_data_wistari_reef documentDigital Sediment data - Wistari Reef WMS Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML
