Surface measurements of partial pressure of CO2 (pCO2), pH, temperature, salinity, and other variables were collected in Casco Bay, Gulf of Maine from 2015-04-23 to 2020-06-12. The project installed continuous monitoring sensors at the Southern Maine Community College pier in South Portland to measure ocean acidification parameters at high temporal resolution. Data was collected by sensors mounted on a frame lowered to the seabed, approximately 1m from the bottom.
Use Cases
- Analyze trends in ocean acidification based on continuous pCO2 and pH measurements
- Model coastal carbon dynamics based on salinity and temperature data
- Assess the impact of urban and riverine inputs on coastal chemistry based on the described location near river outlets
- Validate regional ocean acidification models based on high-resolution time-series data
Strengths
- Data covers a five-year period from 2015 to 2020
- Sensors provide high temporal resolution measurements of key acidification parameters
- Location is described as nearshore and accessible, with historic nutrient data available
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Last updated 2020-06-12 00:00:00; freshness should be verified
- Row count is unknown, which may limit suitability assessment
