Black Sea Nutrient and Sulfide Profiles from 1988 Expedition

Nutrient, sulfide, and oxygen profiles from the 1988 Black Sea Oceanographic Expedition aboard the R/V Knorr. The dataset contains continuous and discrete measurements from the upper 375 meters, collected during cruises 2 through 5 between May and July 1988. It was produced by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical nutrient chemistry gradients in the upper 375 meters.
• Studying sulfide distribution and its relation to anoxic marine environments.
• Correlating discrete rosette-CTD sample data with continuous pumped profiling system measurements.
• Investigating temporal changes in oxygen and nutrient levels across multiple 1988 cruises.

Strengths

• Data includes both continuous pumped profiles and discrete rosette-CTD casts, providing complementary measurement methods.
• Covers a specific time series across four cruises from May 14 to July 25, 1988.
• Focuses on the scientifically significant anoxic environment of the Black Sea.

Limitations

• Column names and exact row/record counts are not provided by any source.
• Sources conflict on the last updated date: one lists a future date (2026-03-05), another lists the original collection date (1988-07 25).
