Visual contacts from research cruises in the Med sea, 1994-2001

Claudio Fossati and Giulia Romè, CIBRA Center for Bioacoustics, University of Pavia

CIBRA Center for Bioacoustics, Univ. of Pavia, organizes research cruises in the Med sea since 1994. Visual and acoustic contacts (1994 - 2001) are available on OBIS-SEAMAP, while acoustic recordings are stored in our Sound library and available upon request.

Data were collected during cetacean research campaigns, acoustic software and hardware development campaigns.

Tracks of the cruises are coarse in June and Sept 1994, June 1995. From 1996 on, tracks are finer.
Data from acoustic contacts are registered in a separate dataset "Acoustic detections from research cruises in the Med sea, 1994-2001".

Overview

This section explains attributes included in the original dataset. OBIS-SEAMAP restricts the attributes available to the public to date/time, lat/lon and species names/counts only. Should you need other attributes described here, you are encouraged to contact the data provider.

Attributes described below represent those in the original dataset provided by the provider.
All attributes are included in the downloadable file (CSV or ESRI File Geodatabase) for "Complete Set of Dataset".
