Surface underway observations of chlorophyll a, temperature, salinity, and other variables were collected during an 11-transect cruise along the U.S. East Coast. The dataset captures a snapshot of key carbon, physical, and biogeochemical parameters related to ocean acidification. Data were collected by the NOAA Ocean Acidification Program aboard the NOAA Ship Gordon Gunter from June to July 2015.
Use Cases
- Modeling the relationship between ocean acidification (OA) indicators and physical parameters like temperature and salinity along the cruise transects.
- Analyzing spatial gradients in chlorophyll a concentration as a proxy for phytoplankton biomass in relation to carbon system variables.
- Calibrating regional ocean models using in-situ surface underway measurements of carbon and biogeochemical parameters from the 2015 ECOA cruise.
Strengths
- Data collection follows a structured 11-transect sampling design orthogonal to the coast.
- Measures multiple concurrent variables (e.g., chlorophyll a, temperature, salinity) for integrated analysis.
Limitations
- Sample size and temporal coverage are limited to a single 5-week cruise in 2015.
- Spatial coverage is restricted to surface waters along a specific cruise track on the U.S. East Coast.
