Cruise 9405 of the R/V Nathaniel B. Palmer collected primary ocean station data in the Pacific sector of the Southern Ocean. The report describes vertical profiling of conductivity-temperature-depth (CTD) and dissolved oxygen, plus water sample processing for salinity, oxygen, nutrients, carbon dioxide, and chlorofluorocarbons. Data acquisition occurred from 14 September to 12 October 1994, targeting a zonal band from 65-72°S in late winter/early spring sea ice.
Use Cases
- Modeling large-scale stratification and circulation based on CTD profile data
- Analyzing ice-ocean interactions based on measurements taken within the sea ice field
- Studying seasonal extremes of water properties based on winter/spring sampling
- Comparing modern measurements with historical stations based on revisit of 16 deep stations
Strengths
- Data covers a largely unsampled region in the Southern Ocean (>60°S)
- Includes multiple measured parameters: CTD, dissolved oxygen, salinity, nutrients, carbon dioxide, and chlorofluorocarbons
- Sampling occurred at seasonal extremes (late winter/early spring)
- Revisited 16 deep stations from previous cruise and WOCE lines
Limitations
- Last updated 1994-10-12 00:00:00; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
