Content and values displayed: The data is displayed in an excel file with spreadsheets representing each of the following spatial scales:
-“Fjord-scale”: The data set includes information on measurements representing vertical profiles at sites distributed along a horizontal fjord gradient: Date, site (station), water depth, temperature, pH, Ωarag, oxygen concentration (O2) and fluorescence
-“Small-scale/kelp-scale”: The data set includes information from 3 consecutive series of parallel deployments over 2-3 days in shallow subtidal kelp habitats (kelp) and neighboring habitats colonized by benthic microalgae and scattered filamentous algae (bare) in Kobbefjord. We provide information on date and time, deployment number (#1-3), and each of the following variables measured ca 50 cm above the seafloor in the two types of habitat (kelp and bare): temperature, pH, salinity, water depth, O2, PAR and Ωarag. In addition, we provide information on pH-variability within 1m3 of kelp forest measured by an array of 16 pH-sensors placed in 4 layers of the kelp forest: 10 cm above the seafloor, 20 cm above the seafloor, in the canopy and in the water column just above the canopy. -“Micro-scale”: The data set includes information on pH at a millimeter scale measured through the boundary layer of 6 different species of macrophytes (Ascophyllum nodosum, Fucus vesiculosus, Saccharina longicruris, Agarum clathratum, Ulva lactuca, Zostera marina) by microelectrode in a laboratory setup. For each point we provide the average and standard deviation (SD) of 3 replicate measurements of each species.
-“Tidal pools”: The date set represents parallel diurnal measurements in a vegetated tidal pool and the adjacent vegetated shore in the inner part of Kobbefjord. For each site and sampling time we provide data on O2, salinity, temperature, pH, total alkalinity (AT), total inorganic carbon (CT), partial pressure of CO2 (pCO2)and Ωarag in the water., Access and reuse: The database is subject to a Creative Commons Attribution-Noncommercial-ShareAlike International licence 4.0.
Contact person for enquiries: Dorte Krause-Jensen, dkj@bios.au.dk., This dataset represents spatiotemporal variability in coastal pH-variability measured in a nested scale in the sub-Arctic Kobbefjord (64⁰10’ N, 51⁰33’ W) which makes part of the extensive Godthåbsfjordsystem near Nuuk, SW Greenland. A sensor array logging pH, oxygen, photosynthetically active radiation (PAR), temperature and salinity was applied on spatial scales ranging from km-scale across the horizontal extension of the fjord, over 100 m-scale vertically in the fjord, 10-100 m scale between subtidal habitats with and without kelp forests and between vegetated tidal pools and adjacent vegetated shores, to cm-m scale within kelp forests and pH was also measured at mm-scale across boundary layers of macrophyte tissue. In addition, we assessed the temporal variability in pH on diurnal and seasonal scales. Based on pH-measurements combined with relationships between salinity, total alkalinity and dissolved inorganic carbon we also estimated variability of the carbonate saturation state for aragonite Ωarag. Fjord-scale data sets were collected during three field campaigns (19 Apr, 18 Jul, 3 Sep 2013), shallow subtidal habitats and microscale data sets represent an intensive campaign (27 August–6 September 2013) and intertidal data were collected ultimo Aug 2014. Methods are described in detail in Krause-Jensen et al. (2015) which also contains a thorough presentation, analysis and discussion of the results., The study was funded by the Danish Environmental Protection Agency
20 within the Danish Cooperation for Environment in the Arctic (DANCEA). L. Meire was funded
by the Research foundation Flanders (FWO aspirant grant) and by Defrost under the Nordic
Centers of Excellence (NCoE) program. O. Geertz-Hansen, Greenland Climate Research Centre,/
Greenland Institute of Natural Resources, Nuuk, is thanked for help with field work. The
study is also a contribution to the Greenland Ecosystem Monitoring program (www.G-E-M.dk)

Photographs taken with a digital camera Nikon Coolpix 950 adapted to a binocular Nikon SMZ. A list attached includes exact locations where seeds were gathered. This dataset is under a Creative Commons Attribution-Non commercial 4.0 International License. 304 jpg files included., Analysis of seed shape in two subspecies of Capparis spinosa collected in Tunisia: Five populations of Subspecies Spinosa; five populations of Subspecies Rupestris. Morphological description of seeds is a required step for the analysis of biodiversity in natural populations and may give clues to understand adaptive strategies in evolution. The cardioid is the curve described by a point of one circumference rolling around another circumference of equal radius. Models based in the adjustment of seed shape with cardioid curves where described previously for Arabidopsis thaliana and the model legumes Lotus japonicus and Medicago truncatula. In this work the model is applied to the morphology of seeds in populations from two subspecies of Capparis spinosa grown in Tunisia. The adjustment of seed images to cardioid curves, followed by statistical analysis of similarity in the complete images as well as in each of four quadrants, allows an accurate description of seed shape. Results show differences in morphology between subspecies. Seeds from Capparis spinosa. subsp. rupestris present higher diversity in shape than seeds from populations of C. subsp. spinosa. This may indicate a primitive condition in the seeds of C. subsp. rupestris associated with non-specialization. The results are discussed in relation to ecological strategies of both subspecies in evolution., Funded through a cooperation between IRNASA-CSIC and National Institute of Research in Rural Engineering, Waters and Forests (INRGREF), University of Carthage, Tunisia., Peer reviewed

DISCRETE MEASUREMENTS OF CO2 AND HYDROGRAPHIC DATA DURING THE GIFT TIME SERIES CRUISES (STRAIT OF GIBRALTAR 2005-2007)
- Huertas, I. Emma
- Ríos, Aida F.
13 files, This dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) in 10 cruises between 2005 and 2007 in the GIFT Time Series Stations located at the Strait of Gibraltar.
pH was measured spectrophotometrically following the Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbances at two different wavelengths is proportional to the sample pH.
Alkalinity was measured using an automatic potentiometric titrator Titrando 794 Metrohm, with a Metrohm 6.0232.100 combination glass electrode and a Pt-1000 probe for temperature measurement following the methodology given by Pérez and Fraga (1987).
Dissolved oxygen was analyzed following the widely applied Winkler method.
Determinations of nitrate, phosphate and silicate were carried out following methods described by Hansen and Grassoff (1983)
Salinity and Temperature were recorded with a CTD probe, Data are part of the EC-funded Integrated Project CARBOOCEAN - Marine carbon sources and sinks assessment Contract no. 511176 (GOCE), more details available at http://www.carboocean.org/, CARBOGIB2005.exc.xlsx.-- Metadata_CARBOGIB2005_Dec2005.xls.-- Metadata_CARBOGIB2005_Dec2006.xls.-- Metadata_CARBOGIB2005_July2007.xls.-- Metadata_CARBOGIB2005_March2006.xls.-- Metadata_CARBOGIB2005_May2005.xls.-- Metadata_CARBOGIB2005_May2006.xls.-- Metadata_CARBOGIB2005_May2007.xls.-- Metadata_CARBOGIB2005_Nov2006.xls.-- Metadata_CARBOGIB2005_Nov2007.xls.-- Metadata_CARBOGIB2005_Sep2005.xls.-- Discrete_measurement_methodology.docx.-- Readme_discrete_2007, Peer reviewed

IMPACTS OF CLIMATE CHANGE ON ORGANISMS IN THE MEDITERRANEAN SEA [DATASET]
- Marbà, Núria
- Jordá, Gabriel
- Agustí, Susana
- Girard, Coraline
- Duarte, Carlos M.
This dataset compiles narrative and quantitative evidences of impacts of warming on organisms living in the Mediterranean Sea published in the literature until year 2014 as well as sea surface temperature values. The search of evidences of impact was conducted using ISI Web of Knowledge and the keywords “ (Mediterranean) AND ((Bio* OR Eco*)) AND ((warming OR temperature)) AND ((Marine OR Ocean*)) NOT ((paleo*))”. Only evidences from articles directly attributing the changes observed in marine biota to warming are included in the dataset. The dataset comprises biological impacts observed after single warming events as well as during longer-term observations. The dataset provides information about the study conducted (i.e. year or period of years of the study, site name and geographical coordinates, spatial scale of the study, species name, taxonomic group, whether the species is sessile or mobile, native or introduced), the type, magnitude and activation energy (Brown et al. 2004) of biological responses.
The values on sea surface temperature (SST) are derived from satellite images. SST is calculated as the mean august SST (SSTaugust) and as the 99th percentile of SST (SST99p) in the year and location the impact was recorded. The SST anomaly is calculated as the SST99p with respect to the averaged august temperature computed for the period 1960-1985.
The calculations to estimate activation energy and detailed information about the sources of SST data are described in Marbà et al. (submitted).

The database compiles published and unpublished data on carbonate (CaCO3) and/or particulate inorganic carbon (PIC) along with particulate organic carbon (POC) stocks if available, in sediments of seagrass meadows and adjacent un-vegetated patches. We considered the total pool of CaCO3 reported without distinguishing between the different biogenic carbonate mineral forms (calcite, Mg-calcite and aragonite). Fourqurean et al. (2012) provided data for 201 sites, and a literature search using both the Web of Knowledge (using the search terms “seagrass*” AND “inorganic carbon*” AND [“calcific* OR sediment* OR CaCO3 OR dissolut* OR diagenesis”]) and Google Scholar (using the search terms “seagrass carbonate”) yielded data for an additional 82 sites. The database was amended with unpublished values for 154 additional sites sampled by the authors. The database compiles data on sediment carbonate concentration for a total of 437 sites, of which 34 corresponded to sand patches adjacent to seagrass meadows. The final database comprises estimates for 403 seagrass vegetated sites, including 219 estimates for sediment surface samples (ca. 1-30 cm depth) and 184 estimates for sediment cores of variable length (149 cores < 100 cm-long, and 35 cores ≥ 100 cm-long).
When only one of the variables, CaCO3 or PIC was reported, the other was estimated assuming that PIC is 12% of the total molar mass of the CaCO3. In most cases, particulate inorganic and organic carbon (PIC and POC) were reported as a percentage of dry weight (%DW), where PIC and POC, in mg cm-3, was calculated as the product of the fraction of sediment dry weight composed by PIC or POC and the dry bulk density (DBD) of a given sediment section (n = 340 sites). When DBD was not reported (n = 113 sites), we used the average DBD (1.03 g cm-3) reported by Fourqurean et al. (2012) for seagrass sediments in the calculations.
