Ocean Country Partnership Programme (OCPP) Vanuatu water sampling results September 2023

Water quality data was collected around Efate island in Vanuatu during September 2023. Sampling focused on rivers, Port Vila Bay, and Emten Lagoon, measuring nutrients, microbiology, and accumulated metals. The dataset was contributed by the Marine Environmental Data & Information Network.

Use Cases

• Assess nutrient pollution levels in rivers based on nitrate, nitrite, ammonium, phosphate, and silicate concentrations.
• Analyze daily fluctuations in microbial contamination based on Colony Forming Units (CFU/100ml) counts.
• Model metal accumulation in coastal waters based on passive sampler results for Cadmium, Chromium, Lead, Nickel, Zinc, Iron, Copper, and Manganese.
• Compare water quality parameters between different environments like rivers, bays, and lagoons.

Strengths

• Data includes multiple sampling campaigns, with microbiology sites visited up to 4 times to assess daily fluctuations.
• Passive samplers were deployed for 5-7 days to assess metal accumulation, providing time-integrated measurements.
• Analysis covers three distinct categories: nutrients, microbiology, and metals, offering a multi-faceted view of water quality.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
