Seafloor Conductivity Temperature and Depth Data from Western Ionian Sea

Over three years of sea bottom Conductivity, Temperature, and Pressure data were collected approximately one meter above the seabed. The dataset was acquired by the INGV/NEMO-SN1 seafloor observatory, part of the EMSO network, during the GNDT-SN1 project. Measurements were recorded from January 2005 through April 2008 in the Western Ionian Sea near East Sicily.

Use Cases

• Analyze temporal trends in bottom water Temperature and Conductivity to study deep-sea warming or salinity changes.
• Correlate Pressure data with tidal cycles or seismic activity for geophysical monitoring.
• Model the relationship between Conductivity-derived salinity and Temperature for water mass characterization in the Ionian Sea.
• Use the continuous 10-minute interval time-series for validating regional ocean circulation models.

Strengths

• Data collection spans over three years, from January 2005 to April 2008.
• Measurements were taken by a dedicated SBE 37-SM sensor on a fixed seafloor observatory platform, ensuring consistent methodology.
• The dataset is part of the EMSO network, a large-scale European research infrastructure.

Limitations

• The specific row count, file size, and data resolution beyond the 10-minute sampling note are unknown.
• Data is temporally stale, with the last update in April 2008 and no indication of ongoing collection.
• Geographic coverage is limited to a single site in the Western Ionian Sea.
