Title of dataset | Seafloor bedforms in the Gulf of Cadiz. C |
Narrative summary of dataset | Videoframe of seafloor displaying bedforms affecting sandy deposits in the continental slope of the Gulf of Cadiz, just downstream of the Strait of Gibraltar: isolated rocky boulder on a gravelly seafloor. The boulder acts as an obstacle to the bottom current, favouring the formation of a longitudinal sandy ribbon superimposed on a small scale and transverse asymmetric ripples. Note the sandy accumulation lee side of the obstacle as well as the two ripple patterns drawing a fishbone feature produced by secondary flows formed on both sides of the boulder. Additionally, note the fast transport and armouring by the MOW toward the ROV |
Summary of processing methodology | These photograms were extracted in readable form from videos recorded using the ARGUS ROV from EMEPC (Portugal). |
