Dataset identification

Title of datasetSeafloor bedforms in the Gulf of Cadiz. C
Narrative summary of datasetVideoframe 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 methodologyThese photograms were extracted in readable form from videos recorded using the ARGUS ROV from EMEPC (Portugal).
