Seafloor Conductivity, Temperature, and Pressure Data from Western Ionian Sea

Nadia Lo Bue's CTD dataset contains sea bottom Conductivity, Temperature, and Pressure measurements from the INGV/NEMO-SN1 seafloor platform. Data was collected approximately 1 meter above the seabed using a SBE 37-SM instrument. The collection period spans from October 2002 through February 2003 as part of the GNDT-SN1 project within the EMSO network.

Use Cases

• Analyzing temporal trends in sea bottom temperature and conductivity from the SBE 37-SM sensor to study seasonal deep-water changes.
• Correlating pressure data with tidal cycles or other oceanographic events recorded during the October 2002 to February 2003 deployment.
• Validating regional ocean models using high-frequency (1 sample/12 min) in-situ conductivity, temperature, and depth measurements from the SN-1 station.
• Investigating water mass properties and stability near the seabed in the Western Ionian Sea site off East Sicily.

Strengths

• Data collected at a high temporal resolution of 1 sample every 12 minutes.
• Provides in-situ measurements from a fixed seafloor observatory (SN-1 station) as part of the established EMSO network.
• Covers a continuous 5-month observation period from October 2002 to February 2003.

Limitations

• Dataset is temporally limited, covering only a single 5-month period with no recent updates.
• Spatial coverage is restricted to a single point location at the Western Ionian Sea site.
• The specific row count, file size, and data format are unknown, complicating initial assessment.
