Organic Geochemistry of Surface Sediments in Jervis Bay, NSW (2008-2009)

50 surface sediment samples from Jervis Bay provide measurements for %TOC, %TN, TOC/TN ratios, and carbon and nitrogen isotopic ratios. Geoscience Australia acquired this data during marine surveys in 2007, 2008, and 2009 using the MV Kimbla. Bathymetric mapping and sampling were concentrated in a 3x5 km survey grid within the southern part of the bay.

Use Cases

• Model carbon cycling in coastal sediments based on %TOC and isotopic ratios.
• Assess nutrient dynamics and organic matter sources based on %TN and TOC/TN ratios.
• Characterise benthic habitats for environmental management based on colocated sediment geochemistry.
• Calibrate remote sensing or bathymetric data with ground-truthed biogeochemical samples.

Strengths

• 50 samples provide a focused snapshot of surface sediment geochemistry.
• Data is colocated with bathymetric mapping and benthic habitat observations mentioned in the description.
• Samples cover two distinct time points (August 2008 and February 2009) for seasonal comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
