Description

Sample raw acoustic datasets acquired from hydrophone array SLiTA (SLim Towed Array, specific for AUV applications) towed by marine autonomous vehicles (e.g, Autonomous Underwater Vehicles, AUVs) [*]  during three STO-CMRE sea trials:

  • PORTOPALO (2013), at Portopalo di Capo Passero, Sicily, Italy, on 18-19 February 2013
  • COLLAB13, at Palmaria Island, La Spezia, Italy, on 30 June - 7 July 2013
  • COLLAB14, at Massa, Italy, on 29-31 October 2014

Access to this dataset is restricted to NATO and H2020 INFORE consortium. This data set is provided to INFORE consortium partners for the purposes of executing tasks under the INFORE Grant Agreement and may not be used for other purposes or further distributed.

The creation of derived products, as well the use in scientific publications must be pre-approved by NATO STO CMRE and acknowledged.

These data are available to partners of NATO Nations after the execution of the project on the basis of existing NATO policies and rules for data release, other memorandum of understanding and agreements, and on the basis of CMRE terms and conditions for data reuse.
