Implications for the understanding of other current plate boundaries, plate Scotia and Ancient; Gibraltar arc. The scientific objectives are focused on the study of the limits of tectonical plates present in the Caribbean (American Plate Limit - Caribbean Plate)

ZEE-1997 Cruise (29HE19970801) carried out on the Research Vessel Hespérides in 1997, ZEE cruise 1997. Plan for hydrographic and oceanographic Spanish Exclusive Economic Zone

FILAMENT Cruise (29HE19970926) carried out on the Research Vessel Hespérides in 1997, Incident flux on the continental shelf between the Strait of Gibraltar and Cape Ghir. The main objectives of the campaign were to quantify the branch of the Canary Current that affects the slope and the continental shelf of northwest Africa between the latitudes of the Strait of Gibraltar and Cape Ghir, its recirculation in the margin near the slope in the form of a jet coastal barocino, and its new integration to the interior ocean in the filament area of ​​Cabo Ghir. Other complementary objectives were to determine the concentrations of dissolved nutrients, respiration rates and productivity, and characterization of the water masses of the area in terms of dissolved aluminum

VIDAL Cruise (29HE19971015) carried out on the Research Vessel Hespérides in 1997, Middle Ocean Channels and Fracture Zones: Interaction and Mutual Recent Evolution of Equatorial and Vidal Channels (Equatorial Atlantic). The main objective of the Campaign has been the study of the geological evolution of Vidal's Mediooceánicp channel, especially in its final section where it interacts with the Barracuda Fracture Zone, as well as in its proximal zone, with the definition of its main tributaries and its possible relationship in the distal turbiditic system of the Orinoco. Specific objectives. 1) Carry out detailed bathymetry in the de-opening zone of the Canal de Vidal, in the vicinity of the Barracuda Fracture Zone. 2) Carry out a high resolution and seismic profile, transversely to the fracture zone and abyssal llanira of Barracuda, in order to recognize its sedimentary fill and the relationship with the adjacent tectonic structures. 3) Carry out detailed bathymetry of the entire course of the Vidal Canal. 4) Carry out a series of high resolution seismic profiles transverse to the valley, to identify their most recent morphosedimentary characteristics. 5) Obtain a detailed bathymetry of the southern area of ​​the Vidal Canal, to the affection of recognizing the presence of a series of important tributes from the area. 6) Carry out a series of seismic profiles in the area of ​​said tributaries, in order to recognize their activity as sources of flows and contributions to the main valley. 7) Make a series of profiles of seismic and bathymetry in the area between the distal valleys of the Orinoco system, in order to certify the possible functional relationship and process level between both depositional systems and sedimentary transfer to the deeper basins of the Atlantic
