Description
Geoscience Australia collected 81 surface seabed sediment samples in Jervis Bay, New South Wales, during August 2008 and February 2009. The dataset provides acid-extractable concentrations of trace elements including Fe, Mn, Co, Ni, Cu, Zn, Ge, As, Cd, and Pb. This work was a contribution to the CERF Marine Biodiversity Hub, with data acquired using the Defence Science and Technology Organisation's Research Vessel Kimbla.
Use Cases
Modeling trace element distribution in coastal sediments based on the 10 measured elements.
Assessing sediment quality and potential contamination in Jervis Bay based on element concentrations.
Correlating benthic habitat types with sediment geochemistry based on the survey's colocated sampling.
Studying seasonal variation in sediment composition based on the August 2008 and February 2009 sampling periods.
Strengths
Includes 81 distinct sediment samples, providing a substantial point dataset.
Measures 10 specific trace elements (Fe, Mn, Co, Ni, Cu, Zn, Ge, As, Cd, Pb) per sample.
Samples are geospatially referenced to a focused 3x5 km survey grid and additional habitat transits.
Data collection involved a dedicated research vessel and was part of a formal marine biodiversity hub project.
Limitations
Row count is unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
Data may reflect geographic/temporal bias inherent to data_gov_au, being limited to Jervis Bay and two months in 2008-2009.
Provenance
Source
Geoscience Australia, contributed via the Australian Ocean Data Network.
Collection Method
Marine surveys (GA303, GA305, GA309, GA312) acquiring surface sediment samples via the RV Kimbla for acid-extractable element analysis.
Time Range
August 2008 and February 2009 (surveys also occurred in 2007).
Freshness
Last updated 2026-06-27 21:15:57.835005; freshness should be verified.
Geography
Jervis Bay, New South Wales, Australia, focusing on a 3x5 km Darling Road Grid and representative habitat transits.
