BRITICE-CHRONO: Marine Geophysical Survey of the Irish Sea (2014)

A marine multibeam, geophysical and sampling survey conducted from 16 July 2014 to 25 August 2014 in the Irish Sea, Galway Bay, Donegal Bay, and Malin Sea. Scientists from the BRITICE CHRONO Consortium, led by PI Colm O'Cofaigh, collected sea floor bathymetry, sub-bottom seismic profiling data, and seabed samples using vibrocorers and piston corers. Data are archived by the British Geological Survey (BGS), Durham University, and Bangor University.

Use Cases

• Modeling past ice sheet retreat dynamics based on collected seabed sediment cores.
• Mapping sea floor bathymetry for geological and oceanographic studies based on multibeam sonar data.
• Analyzing sub-seafloor stratigraphy for paleoenvironmental reconstruction based on sub-bottom profiler data.
• Constraining the timing of deglaciation events based on the sediment sampling effort described.

Strengths

• Data collection employed specific, high-resolution instruments including EM120 and EM710 multibeam systems and an SBP120 sub-bottom profiler.
• Survey involved a large vibrocoring effort using a 6 m BGS vibrocorer and a 12 m NOC Piston corer.
• Project is a funded consortium effort supported by the Natural Environment Research Council (NERC).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are restricted to project partners for a 5-year moratorium period, limiting immediate public access.
