Maximum photochemical efficiency (Fv/Fm) measurements of phytoplankton collected via Fast Repetition Rate Fluorometry on the RV L'Astrolabe. Data were gathered continuously at one-minute intervals from seawater at 3 meters depth during a voyage from Dumont d'Urville to Hobart between February 27 and March 4, 2007. The dataset is provided by the Australian Ocean Data Network.
Use Cases
- Modeling primary production based on the described parameters of Fv/Fm, absorption cross-section, and chlorophyll concentration.
- Analyzing phytoplankton stress responses by tracking variations in the maximum quantum yield (Fv/Fm) over time.
- Correlating phytoplankton photochemical efficiency with physical and chemical oceanographic properties collected during the same cruise.
Strengths
- Data were collected at a high temporal resolution of one-minute intervals.
- Measurements were taken under controlled dark-adapted conditions with a 15-minute adaptation period.
- The dataset covers a specific transect from Antarctica (Dumont d'Urville) to Australia (Hobart).
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 the single cruise from data_gov_au.
