Data of hydrographic properties (pressure, temperature, salinity and turbidity) collected by an autonomous hydrographic profiler deployed in the axis of the Palamós Canyon (NW Mediterranean), and near-bottom time series of turbidity and currents. Additionally, data (temperature, salinity and turbidity) collected during an hydrographic CTD transect across the Palamós Canyon's head is also provided, Increases of water turbidity and suspended sediment transport in submarine canyons have been associated with high-energy events such as storms, river floods and dense shelf water cascading (DSWC), and occasionally with bottom trawling along canyon flanks and rims. To assess the variations on the water column turbidity and sediment transport in the Palamós Canyon linked to both natural and trawling-induced processes, an autonomous hydrographic profiler, as well as a near-bottom current meter and a turbidimeter were deployed in the canyon axis (929 m depth) from February to June 2017, covering a trawling closure (February) and trawling activities (March-June). Periods of enhanced water turbidity during the trawling closure were mostly associated with storms and DSWC events, transporting turbid dense waters into the canyon. In absence of such events, the water column displayed low suspended sediment concentrations (~ 0.3 mg L− 1) until the trawling season began, when particulate matter detachments, ranging between > 1 mg L− 1 and 3.8 mg L− 1, were observed at the water depths where the trawling grounds are found. During the trawling closure, high near-bottom suspended sediment fluxes (35–44 g m− 2 s− 1) were sporadically registered at ~  920 m depth associated with a major storm and DSWC event. Smaller but more frequent increases of near-bottom suspended sediment fluxes (0.1–1.4 g m− 2 s− 1) were recorded during trawling activities. Despite these smaller trawling-induced suspended sediment fluxes, 30 days of continuous bottom trawling activity transported a total amount of 40 kg m− 2, of similar magnitude to that generated by a major DSWC event (50 kg m− 2). Since bottom trawling in Palamós Canyon is practiced on a daily basis throughout the year, a much larger contribution of anthropogenically derived water turbidity and suspended sediment transport can be expected, Ministerio de Economía y Competitividad (España) MINECO/CTM2015-65142-R, MINECO/BES-2016-076983; Ministerio de Ciencia, Innovación y Universidades (España): AGAUR/2017/SGR-863, AGAUR/2017/SGR-1241, No

PALEOPAC CRUISE, RV HESPÉRIDES

  • Palanques, Albert
  • CSIC - Unidad de Tecnología Marina (UTM)
PALEOPAC Cruise (29HE19960309) carried out on the Research Vessel Hespérides in 1996, The PALEOPAC campaign was developed in the South Pacific in March 1996. During the campaign, kasten cores, gravity corers, maxicores, bathymetric profile with EK 500 and EM 12 probe and very high resolution profiles with BPS parametric probe were taken. The concrete areas of the study have been the southern Chilean margin around the Gulf of Penas, the "sea mounts" located in the basins off the Chilean continental margin and the Nazca Ridge. The intensive zone of work and sampling has been the Nazca Ridge. The purpose of the campaign has been to take cores in areas of the Pacific that allowed to study the paleoceanographic variability from the record of indicators of paleotemperatures and paleoproductivities accumulated in the sediment. The analysis of parameters such as the biogenic opaline, the content of organic matter and certain radioisotopes make it possible to reconstruct the records of paleoproductivity, paleotemperature and ocean circulation during periods of hundreds of kiloyears.
