Open access. Please, contact corresponding author in case of doubts, Description: The Malaspina2010_chlorophyll.xlsx file contains the fluorimetric chlorophyll a data of the circunnavigation expedition Malaspina 2010, which took place between 14/12/2010 and 14/07/2011 on board the BIO Hespérides. The data presented here were obtained between 16/12/2010 and 11/07/2011. The date and position of the sampling stations are listed in the third sheet of the file. Methods: Water samples for fluorimetric chlorophyll a (Chl a) determination were collected from 3 m depth with a 30-liter Niskin bottle and from selected depths between 10 and 200 m with a Rosette of 24 10-liter Niskin bottles attached to a CTD probe. Chl a determination was carried out as described in Estrada et al. (2012). Briefly, between 200 and 500 cm3 of seawater were filtered through GF/F glass fiber filters that were subsequently frozen at -20°C and, after a minimum of 6 hours, introduced in vials with acetone 90% and left for 24 hours in the dark, at 4ºC. The Chl a concentration in the acetonic extracts was measured with a Turner Designs fluorimeter calibrated with a pure Chl a standard (Sigma-Aldrich); no phaeopigment correction was applied. Size-fractionated analyses of Chl a were performed for samples from surface, the 20% surface PAR and the deep chlorophyll maximum. The analyses were carried out by sequential filtration of a 500 cm3 of seawater through Poretics (polycarbonate) membrane filters of pore sizes 20 μm, 2 μm and 0.2 μm, which were subsequently treated as the GF/F ones (Estrada, 2012), This work was supported by Consolider-Ingenio 2010, CSD2008-00077 of the former Spanish Ministerio de Ciencia e Innovación (ES) (now www.ciencia.gob.es) and the Consejo Superior de Investigaciones Científicas (CSIC) (ES)., Authors; Methods; Station positions; leg 1; leg 2; Legs 3-4; leg 5; leg 6; leg 7; References, Peer reviewed

Description: The Malaspina2010_chlorophyll.xlsx file contains the inorganic nutrient concentration data of the circunnavigation expedition Malaspina 2010, which took place between 14/12/2010 and 14/07/2011 on board the BIO Hespérides. The date and position of the sampling stations are listed in the “Data” sheet of the file. Methods: Water samples for measurement of the concentration of nitrate, nitrite (nitrate + nitrite in leg 1), phosphate and silicate were collected from 3 m depth with a 30-liter Niskin bottle and from selected depths between 10 and 200 m with a Rosette of 24 10-liter Niskin bottles attached to a CTD probe. Inorganic nutrient concentrations were determined by means of a Skalar autoanalyzer, following the standard spectrophotometric procedures described in Grasshoff et al. (1999) and Blasco et al. (2012); in leg 1, nitrite was not determined separately and phosphate was measured using a manual method (Vidal et al. 2012), This work was supported by Consolider-Ingenio 2010, CSD2008-00077 of the former Spanish Ministerio de Ciencia e Innovación (ES) (now www.ciencia.gob.es) and the Consejo Superior de Investigaciones Científicas (CSIC) (ES), Peer reviewed

The dataset comprises mass mortality events impacts observed at discrete events generally related to warming episodes across the Mediterranean. The dataset provides information about the year, season, geographic coordinates, protection status of the geographic location, species phylum, species name, the degree of mortality impact, depth range of the mortality and reported biotic and abiotic mortality drivers of the event, The Mass Mortality Events (MME-T-MEDNet) dataset compiles information reported on mass mortality events of species in the Mediterranean Sea affecting different organism dwelling in coastal ecosystems, We acknowledge the financial support by the Prince Albert II de Monaco Foundation (MIMOSA project nº 1983) and the project MPA-ADAPT funded by Interreg MED program (European Regional Development Fund)

This live data set reports gross primary production (GPP), community respiration (CR) and net community production (NCP) of oceanic plankton communities. The methods used to measure GPP, CR, and NCP varied; these include oxygen evolution in dark-light bottles (Carpenter 1965; Carrit and Carpenter 1966),tracer additions (14C additions, SteemanNielsen 1952, and 18O-labeled H2O, Bender etal. 1987), incubation-free methods, including analyses of triple oxygen isotopes (Luz etal. 2000), O2:Ar ratios (Emerson 1987; Spitzer and Jenkins 1989; Emerson et al. 1993),non-intrusivebio-optical (OPT) methods (Claustre et al. 2008), fast repetition rate fluorometry (FRRF, Kolber and Falkowski 1993), and oxygen sensors mounted on gliders (Tengberg et al. 2006; Nicholson et al. 2008) and buoys (Boutin and Merlivat2009). Characteristics of each method are discussed by Robinson and Williams (2005)and Duarte et al.(2013).

The data shown in this table were compiled from the literature by conducting a Boolean search in Google Scholar using the word combinations “seagrass accretion rate” “mangrove accretion rate” and “salt marshes accretion rate”.From each study, the geographic area where the data were obtained, the sediment accretion and/or soil elevation rates, the method used and the source are reported in the table. For the method used, a broad explanation of the RSET (Rod Surface Elevation Table) and the MH (marker horizon) techniques is presented in Cahoon et al. (2006). This compilation is a contribution to the CSIRO Costal Carbon Cluster project. The methodology used is widely explained at: Cahoon, Donald R., Philippe F. Hensel, Tom Spencer, Denise J. Reed, Karen L. McKee, and Neil Saintilan. "Coastal wetland vulnerability to relative sea-level rise: wetland elevation trends and process controls." In Wetlands and natural resource management, pp. 271-292. Springer Berlin Heidelberg, 2006., These data include representative values of accretion and elevation rates in vegetated coastal habitats around the world. The values presented correspond to the accretion rates reported by different studies in different areas. In the cases where, in a same study, two different values were reported for the same system (e.g. upper vs. lower marsh)an average value is reported in this table. Attached goes a list of references.

The data set includes qualitative and quantitative data, since it contains studies where changes in seagrass meadow extension, cover and /or density are identified from expert judgement as well as studies that quantified the magnitude and rates of the changes reported. The absolute and relative rates of change of seagrass extent, meadow depth limits, cover and shoot density are calculated as described in Marbà et al (submitted). The meadows are categorized as declining (final area < 90% of initial area, net % cover abosolute change < -10, or µ density < -5% yr-1), increasing (final area >110% of initial area, net cover change > 10 % yr-1, or µ density > 5% yr-1) or without detectable change (final area within <90 % of initial area, -10 % yr-1 < net cover change < 10 % yr-1, or -5 % yr-1 < µ density < 5 % yr-1) following Waycott et al (2009) for area and Calleja et al (2007) for density criteria., Access and reuse: This dataset is subject to a Creative Commons Reconocimiento-NoComercial-CompartirIgual 4.0 Internacional License., This dataset compiles qualitative and quantitative information on the stability (i.e. decline, steady state, expansion) of the seagrass (Posidonia oceanica) in the Mediterranean Sea between years 1842 and 2009.

Human evolution, Red ochre, Shells, Data set on the joint use of shells and red ochre by humans. Reports of the joint use of red ochre and shells by humans are rapidly growing in number, including reports for both modern humans and Nearderthals. Existing records track the reconstructed dispersal of modern humans including findings of the joint use of red ochre and shells in Africa, Eurasia, Australia, and America ranging from paleorecords starting in 250 ka to present. Numbers show, for paleoanthropological evidence, the dates in ka, when reported. When multiple reports were available for a given region the oldest one is shown.
