ISIMIP-2a climate data cutout provided for Sardinia in the framework of SIM4NEXUS

The objective of the IMR-2009615 cruise was to study the distribution of fish and plankton in relation to the occurrence of Lophelia cold-water coral reefs and the general topography in the Traena Deep coral reef field. The acoustic data were collected using the Simrad ER60 scientific echosounder at a cruising speed of 10 knots. Abundance estimations of fish were generated for the 38 kHz data. Three other operating frequencies were used during the survey (18, 120 and 200 kHz) for trace recognition purposes. Echograms were scrutinized using Large Scale Survey System-software. The allocation of area backscattering strengths to species was made by comparison of the appearance of the echo recordings to trawl catches and video recordings. This dataset contains three hundred and sixty (360) vertical profiles of plankton and fish abundance expressed as Nautical Area Scattering Coefficient (NASC) determined from acoustics measurements at 38 kHz. Abundances expressed as NASC (meter square per nautical mile square) can be converted to numbers of individuals using "target strength to length" relationships for the targeted species/group. For single species these relationships can be determined through in situ measurements of target strength during the survey and the size distribution of the insonified fish. The number of fish (N) in a particular area can be calculated using standard equations, e.g. Foote et al. (1987), Toresen et al. (1998), Roa-Ureta and Nikilitschek (2007).

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI).

This dataset is operationally produced by the atmospheric dispersion models applied in ICARUS and contains data stored in two main subfolders as follows: 1) Folder “Air quality data of Representative days” which includes air quality data for the Representative days (RD) which were estimated by the EUROCORDEX climate data. This data has been derived from the application of a nesting approach at the urban scale of the Eulerian WRF/WRF-Chem model in the 9 pilot cities addressed in ICARUS i.e. Thessaloniki, Athens, Roskilde/Copenhagen, Basel, Brno, Milan, Madrid, Ljubljana and Stuttgart. On the urban scale, nine (9) nests with dimensions 2x2km have been used consisting of 42x42 grid cells each. Daily concentrations were produced and stored for NO2, O3, PM10, PM2.5. Data are stored in various subfolders named according to the city to which they are referring to and in further subfolders named according to the policy/measure assessed. Within these subfolders the filename convention is the following: Domain/date of the RD. 2) The “GHG” folder which includes GHGs (CO2 and CH4) concentration data calculated for each ICARUS city under the BaU emission scenario. The filename conventions is the following: Cityname.csv
