Geoscience Australia collected 18 samples of plant and algae tissues from Jervis Bay, NSW. The data includes %TOC, %TN, TOC/TN ratios, carbon and nitrogen isotopic ratios, and major and trace element concentrations. Samples were acquired during marine surveys in June and August 2008 and February 2009, focusing on abundant red algae like Gracilaria edulis and Acrosorium venulosum.
Use Cases
- Analyze nutrient source and cycling in coastal ecosystems based on carbon and nitrogen isotopic ratios.
- Model elemental composition and biogeochemical processes based on major and trace element concentrations.
- Study the geochemical signature of specific algal genera based on samples from Gracilaria edulis and Acrosorium venulosum.
- Assess environmental conditions in Jervis Bay based on total organic carbon (%TOC) and total nitrogen (%TN) data.
Strengths
- Data is from a focused 3x5 km survey grid (Darling Road Grid) within Jervis Bay.
- Includes 18 samples with multiple geochemical measurements per sample.
- Samples are temporally distributed across three distinct collection periods in 2008 and 2009.
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.
