NABE: North Atlantic Bloom Survey Bottle Cast Data

NE Atlantic observations from the 1989 North Atlantic Bloom Survey aboard the ATLANTIS II. The dataset contains three files with measurements of physical properties, nutrient chemistry, and biological pigments and organisms collected via bottle casts. It was submitted by Peter G. Brewer of the Woods Hole Oceanographic Institution as part of the Joint Global Ocean Flux Study.

Use Cases

• Analyzing phytoplankton bloom dynamics based on chlorophyll-a and pigment data.
• Studying nutrient stoichiometry and carbon cycling from nitrate, phosphate, silicate, and carbon dioxide measurements.
• Modeling water column structure using concurrent pressure, depth, temperature, and salinity profiles.
• Investigating microbial community composition from data on bacteria, flagellates, and plankton.

Strengths

• Contains a multi-faceted suite of concurrent physical, chemical, and biological measurements from a defined experiment.
• Covers a specific, important oceanic event (the North Atlantic Spring Bloom) over a four-month period from April to July 1989.
• Originates from a major oceanographic institution (Woods Hole Oceanographic Institution) and a coordinated international study (JGOFS).

Limitations

• Critical metadata is missing, including row counts, specific column names, file size, and license information.
• Conflicting 'last updated' dates (1989 and 2026) create uncertainty about data currency and potential reprocessing.
• Original data format (diskette) and sparse column documentation may require effort for modern analysis.
