Line W Hydrography with CFC Tracers from 2006 Oceanus Cruise

April 5th to 14th, 2006 hydrographic data from 17 full-depth casts along Line W in the Northwest Atlantic. The dataset includes calibrated CTD measurements of pressure, temperature, salinity, and dissolved oxygen, plus water sample analyses for dissolved chlorofluorocarbons (CFCs 11, 12, 113). It was collected by NOAA NCEI during a research cruise on the R/V OCEANUS.

Use Cases

• Calibrating CTD sensor readings for salinity and dissolved oxygen using shipboard water sample analyses.
• Analyzing the distribution of transient tracers like CFCs to study ocean ventilation and water mass age.
• Profiling full-depth ocean properties including conductivity, temperature, and pressure along a specific transect.
• Studying current velocities and shear using Lowered Acoustic Doppler Current Profiler (LADCP) data from the casts.

Strengths

• Includes 17 full-depth hydrographic casts, providing detailed vertical profiles.
• Data is calibrated, with salinity and oxygen values from water samples used to adjust CTD sensor readings.
• Contains analyzed measurements for multiple chlorofluorocarbon species (CFCs 11, 12, 113).
