If you intend to work with this data set please do not hesitate to contact the authors to discuss cooperation possibilities. The backside of common tiles was selected as substrate. Tiles have the following dimensions, length:heigth = 15:15 cm (225 cm²) and are fixed with two screws and washers to a PVC frame. The latter is connected to the wall with a stainless steel bolt. A square pattern on the tiles allows easy analysis of the percentage cover of species. This pattern has a size of 1.75 cm between the middle of adjacent ridges.

  • Abstract: Sediment cores were obtained from the continental shelf of the Gulf of Cadiz (North East Atlantic), with water depth ranging from 18 to 32 m. Cores were retrieved in Summer and Autumn 2006 on board of the R/V Mytilus in the framework of the EMIGAS Spanish project ('Zonas de emisión de gases efecto invernadero en los sistemas litorales: influencia de las entradas costeras y del metabolismo bentónico'). Five sampling stations were selected in two different areas: the Bay of Cádiz and its outer region (BOX BC02, BOX BC04, BOX BC05), and the Guadalquivir prodelta (BOX GL03, BOX GL04), which is characterized by a high fluvial supply and a moderate hydrodynamic regime. Major and minor elements (Si, Ti, Al, Fe, Mg, Ca, K, Na, P, S) and trace elements (Mn, V, Cr, Ni, Cu, Zn, Rb, Sr, Y, Zr, Ba, and Pb) show differences in bulk chemical composition between the two areas. Trace metals (V, Cr, Ni, Cu, Zn, and Pb) are found at lower levels in the Bay of Cádiz compared to the Gualdalquivir prodelta. Relatively high concentrations of Zr and Y, commonly associated with the heavy minerals fraction, are found in the top sediment layers of the Bay of Cádiz, and are attributed to the enrichment of heavy minerals related to selective transport.

  • Abstract: Sediment cores were taken from the continental shelf of the Gulf of Cadiz (North East Atlantic) in the framework of the EMIGAS Spanish project ('Zonas de emisión de gases efecto invernadero en los sistemas litorales: influencia de las entradas costeras y del metabolismo bentónico'). Sampling stations were selected in two areas of the Gulf of Cádiz: a) the Bay of Cádiz and its outer region (n = 5), and b) the Guadalquivir prodelta (n=4). The data reported in this work were collected during 3 cruises on board RV 'Mytilus,' covering 3 seasonal periods: June 2006, November 2006, and February 2007. We obtained porewater profiles of total alkalinity (TA) and pH using a refined protocol based on the original method designed by Gomez-Parra and Forja (1994). pH was measured in 2 mL of pore water using a glass-combined electrode calibrated in the total pH scale using a TRIS buffer solution. TA was computed from the titration curve with 0.1 M HCl by means of the equivalent volume (Methrom, 794). Near-bottom water pH varied in the ranges of 7.90 – 8.10 in the Bay of Cadiz, and 8.02 – 8.12 in the Gualdaquivir prodelta, whereas TA ranged from ~2200 – 2300 μmol kg−1 in both areas. Porewater profiles of TA increased with depth and with decline in pH, with the highest maximum values of 12406 μmol kg−1 and 19761 μmol kg−1 recorded below 10 cm depth in Summer and Autumn in Guadalquivir prodelta area.

  • Abstract: Organic carbon (OC), total nitrogen (TN), and carbon isotope ratio (δ13C) were measured in sediment cores to constrain the relative contribution of marine and terrestrial sources of organic matter (OM) in the continental shelf of the Gulf of Cádiz. Five sampling stations were selected in two different areas: the Bay of Cádiz and its outer region (BOX BC02, BOX BC04, BOX BC05), and the Guadalquivir prodelta (BOX GL03, BOX GL04), which is characterized by a high fluvial supply and a moderate hydrodynamic regime. C/N and δ13C data show that sedimentary OM is a mixture of marine and terrigenous OM with larger contributions from marine sources in the Bay of Cádiz, and terrestrial sources in the Guadalquivir prodelta.

  • Abstract: We use laboratory shearing experiments to smeasure the frictional properties of fault related rocks and their precursors depending on the lithology, presence of pore fluid, effective normal stress, and temperature. Conditions are appropriate for the surface to several kilometres depth on the Alpine Fault (from 50-100 MPa, 22-160 °C, fluid-saturated).

  • Abstract: Sediment cores were taken using a mini-box corer (25 × 25 × 55 cm) during the 2007-2008 austral summer under the framework of the Antarctic Brazilian Program (PROANTAR). Four cores were sampled in two different areas: a) Deception Island, in the proximity of the Neptune submarine volcano (core DCP01) and Fumarole Bay (core DCP02), and b) Penguin Island, 500 m offshore from penguin colonies (core PGI01) and in the outer King George Bay, 500 m offshore of the southern giant petrel colonies (core PGI02). Major elements (Si, Al, Fe, Mg and Ca) and trace metals (Mn, V, Cr, Ni, Cu, Zn and Pb) show differences in bulk chemical composition between the two areas. Trace metals (Cr, Cu and Ni) are found at lower levels in sediments from Deception Island (11 - 19 mg kg-1, 22 - 42 mg kg-1 and 0.9 - 3.3 mg kg-1) compared to Penguin Island (49 - 82 mg kg-1, 30 - 60 mg kg-1 and 20 - 35 mg kg-1), whereas Zn levels are comparable (42 - 65 mg kg-1 and 43 - 70 mg kg-1, respectively).
