Arctic Ocean Hydrographic and Bio-Optical Profiles from 2010

August 21 to September 8, 2010 data from an Acrobat towed profiler near Barrow, Alaska. The dataset contains hydrographic, chlorophyll and CDOM fluorescence, and optical backscattering measurements collected from the R/V Annika Marie. It was gathered by the organization SCIOPS.

Use Cases

• Analyze chlorophyll fluorescence (µg/L) against temperature and conductivity to study phytoplankton biomass distribution.
• Correlate CDOM fluorescence with hydrographic data like latitude and longitude to trace dissolved organic matter sources.
• Model particulate backscattering at 660 nm as a function of depth and bottom depth to infer suspended particle loads.
• Re-calculate water density from temperature and conductivity data where the original software returned -999.999 for sub-zero temperatures.

Strengths

• Data spans a 19-day field campaign in August-September 2010.
• Includes multiple sensor measurements: CTD, chlorophyll fluorescence, CDOM fluorescence, and optical backscatter.
• Profiles cover from near-surface (1-m) to near-bottom or 60 meters maximum depth.

Limitations

• Data collection was incomplete for some transects due to a leaky motor can.
• The dataset's size, row count, and specific column details are unknown.
• Density calculations require user recalculation for temperatures below 0°C where values are -999.999.
