June 2-13, 1993 data from the Norwegian Sea, collected during the Global Ocean Ecosystems Dynamics (GLOBEC) program. It contains biological, physical, and nutrient measurements from bottle, CTD, and net casts aboard the A.V. HUMBOLDT and JOHAN HJORT research vessels. The data were contributed by multiple institutions and archived by NOAA's National Centers for Environmental Information.
Use Cases
- Analyze chlorophyll a, b, c concentration profiles from bottle data to study phytoplankton biomass and community composition.
- Correlate temperature and salinity profiles from CTD data with zooplankton species abundance from net tows to identify habitat preferences.
- Map the spatial distribution of specific zooplankton species identities and abundances across the Norwegian Sea sampling stations.
- Investigate nutrient profiles alongside physical data to assess factors limiting primary productivity during the early summer period.
Strengths
- Data collected during a focused 12-day research cruise, providing a synoptic view of conditions.
- Includes multiple complementary data types: bottle chemistry, CTD physics, and net biological samples.
- Associated with the international GLOBEC program, indicating standardized collection protocols.
Limitations
- Limited temporal coverage to a single two-week period in June 1993.
- Unknown sample size (row count) and geographic extent of sampling stations.
- Data is over 30 years old, which may limit relevance for studying contemporary ocean change.
