Description 
Summary

Samples of the bottom surface, sub-bottom layers and rocks have been collected on the continental shelf and slope from June 1974 to October 2009, under the SEPLAT programme. The different samples were collected in the following way: a) bottom surface sediments - Shipeck, Van Veen and Smith McIntyre; b) sub-bottom layers - Gravity Corer; and c) rock samples - Cnexo-Ville. For each sample we have the following information: latitude, longitude, depth, hour, day, month and year. For each sample of bottom surface sediment we have recorded the following characteristics: colour, macroscopic classification, statistical parameters, total carbon, total organic carbon, carbonate and clay for the Algarve coast. We have published four sediment information charts, covering from Cape Roca (west of Lisbon) to Guadiana river mouth (South Spanish border). Furthermore, we have some seismic profiles and some side scan coverage for the Portuguese shelf. Other relevant information: water column sediments, temperature, salinity and turbidity data.
