It relies on a Comma Separated Values file and it is composed by 108687 records. Due to its long temporal coverage, it is classifiable as Long Term Ecological data. Due to the long temporal coverage, the great part of parameters changed collection and analysis method in time. These variations are reported in the database. A long term database can be useful for multiple purposes. This database has been released under a research project focused on Open Science principles application to marine ecology, it is also deposited in B2Share repository (https://b2share.fz-juelich.de/records/f772ed02dcd1403a86fac5a6a19005ef) and metadata are available in DEIMS-SDR (Dynamic Ecological Information Management System - Site and dataset registry, https://deims.org/dataset/38d604ef-decb-4d67-8ac3-cc843d10d3ef).

However, trait data are often scattered and standardised terminology that transcends taxonomic and biogeographical context are generally missing. As part of the development of a global trait database of marine species, we collated trait information for European seaweeds and structured the data within the standardised framework of the World Register of Marine Species (WoRMS). We collected 45,175 records for 21 biologically and ecologically relevant traits of seaweeds. This resulted in a trait database for 1,745 European seaweed species of which more than half (56%) of the records were documented at the species level, while the remaining 44% was documented at a higher taxonomic level and subsequently inherited at lower levels. The trait database for European seaweeds will serve as a foundation for future research on diversity and evolution of seaweeds, and their responses to global changes. The data will contribute to developing detailed trait-based ecosystem models, and will be an important tool to inform marine conservation policies. The data is publicly accessible through the

Un contributo allo studio del problema relativo all'interpolazione di dati giaciturali

D'altra parte, la ricostruzione dei rapporti tra assetto giaciturale delle formazioni geologiche e superficie topografica risulta particolarmente utile ai fini della previsione di suscettibilità da frana. In questo ambito si colloca lo studio di Mentemeyer & Moody (2000) che individua un indice (TOBIA) che esprime l'angolo di intersezione tra la superficie topografica ed il piano di giacitura. In quest'ottica ottenere mappe giaciturali continue e distribuite sul territorio consentirebbe di disporre di un dato importante per la valutazione della propensione al dissesto di un territorio e/o per altri scopi. La prima difficoltà riscontrata è insita nella natura del dato angolare e interessa i valori di immersione ed il loro campo di variabilità (0-360°). Si prenda come esempio il caso di due giaciture che immergono quasi verso nord (10° e 350°). I due piani differiscono per immersione di soli 20° ma non considerando la natura angolare del dato, i due angoli vengono interpretati come aventi una differenza di 340 unità. In un qualunque punto che si trovasse equidistante tra le due precedenti giaciture, il valore predetto da un qualunque metodo interpolativo classico sarebbe prossimo a 180°; un valore cioè assolutamente discordante da quello che è il vero assetto locale. Un ulteriore elemento di complessità è relativo alla rappresentazione degli stati rovesciati che sono caratterizzati da valori di immersione ed inclinazione talvolta anche simili a quelli degli strati diritti, ma con significato geologico estremamente diverso. Partendo da queste considerazioni, la nota presenta i risultati di uno studio svolto in corrispondenza di un'area dell'Appennino centrale (circa 38 km^2), scelta perché quasi priva di coperture detritiche, con dati giaciturali ben distribuiti e assenza di faglie di notevole rigetto. I dati giagiturali presenti sulla cartografia geologica a disposizione sono stati opportunamente digitalizzati e i valori di immersione ed inclinazione sono stati archiviati come attributi tabellari del dato geometrico. È stata poi realizzata una fase di rilievo di campagna al fine di costruire un dataset di validazione con lo scopo di “misurare” la qualità dell'interpolazione effettuata. La procedura di interpolazione proposta ha considerato la normale al piano come elemento di rappresentazione del dato geologico giaciturale. Sostanzialmente, richiamando il concetto di rappresentazione di un piano nello spazio, come proposto dalla geometria cartesiana, il piano può essere rappresentato attraverso il versore ad esso normale. Operando con il versore normale al piano giaciturale ed in particolare con le sue tre componenti cartesiane, sono stati superati i problemi prima richiamati. In particolare questo approccio ha permesso anche di trattare i piano rovesciati senza distinguerli da quelli diritti, in quanto, qualora lo strato sia rovesciato, la componente del versore lungo la verticale risulta negativa. Sono stati sperimentati metodi di interpolazione bi e tri-dimensionale. Nel primo caso, utilizzando alcuni moduli di GRASS GIS (v.surf.idw e v.surf.rst), ci si è basati sul concetto dell'inverso della distanza pesata e delle spline with tension (Hofierka et al. 2002). Nel secondo, l'interpolazione tridimensionale è stata eseguita utilizzando sempre l'approccio delle spline with tension. Il risultato principale del processo interpolativo sono ovviamente le mappe di immersione e inclinazione. La mappe in output evidenziano chiaramente le strutture presenti. I risultati di queste operazioni sono stati poi validati attraverso il raffronto effettuato con il dataset ulteriore acquisito ad hoc in campagna. Lo studio dei residui ha messo in evidenza come i risultati migliorino sensibilmente laddove l'interpolazione sia effettuata su base tridimensionale. La nota illustra quindi il miglioramento ottenuto con il processo di interpolazione tridimensionale ed i risultati finali ottenuti nel corso del lavoro.

A GIS tool to evaluate marine traffic spatio-temporal evolution using semaphore data. An application on French coastal zone

Data about marine activities exist but they describe only a specific part of the traffic (e.g. commercial one with AIS data), or are not available for public uses (fishing data) or remains sparse or unstructured (boating). In France, one precious source of information are the Sémaphores, which are located along the coasts and register continuously the marine traffic, noting down each boat observed. Currently, the use of this data remains dedicated to marine traffic security topics, but could be very useful for public management of coastal zone. This note presents an Open Source GIS tool which quantifies the marine traffic on specific routes using sémaphore data. First of all, raw data are standardised, then an automatical procedure recognizes the specific route crossed by the single boat and traces (following the shortest path rule) a synthetical path along a geometrical network. These paths share segments along the network and this allows to group traffic fluxes in order to calculate the most frequented zones. Moreover, is under implementation an additional function to simultaneously analyse data from different sémaphores and different years of recordings. In this way, the tool presented can provide a useful base to evaluate spatial and temporal evolution of pressures due to the traffic on marine areas and activities.

The estimated flood flow frequency in a particular cross-section of a riverbed for a given return... more The estimated flood flow frequency in a particular cross-section of a riverbed for a given return period is a topic of great interest for its application in hydrological, geomorphological and hydrogeological fields. Nevertheless, to establish a one-to-one relationship between rainfall and peak flow is a difficult problem to solve, due to the great number of factors involved (intensity and distribution of rainfall, hydromorphological characteristics of the watershed, type and distribution of vegetation, soil saturation conditions, etc.). In Italy, the Tiber River Basin Authority has developed a method to evaluate peak flows in the watersheds within the Tiber Basin. The relationship between rainfall depth with an assigned return period (RP) and the duration of the event was determined using data from 165 gauging stations throughout the Basin and in the neighbourhoods with respect to rainfall from 1 to 24 h and/or from 1 to 5 days. To calculate the peak flow with an assigned RP in small watersheds (area < 100 km 2), the Tiber River Basin Authority proposed a methodology that combines the results of regional precipitation analysis of a duration from 1 to 24 h with the Curve Number method, which allows the volume of net rainfall (i.e., the rainfall that contributes to producing the peak flow) to be quantified. Such procedure includes the calculation of various parameters (run-off time, local rainfall and areal rainfall, net rainfall) in order to obtain the value of peak flow. To facilitate the use of this procedure, a WebGIS system has been developed, based on a series of scripts that calculate the values for the above parameters. The user only has to choose the point corresponding to the section of the channel in order to determine the peak flow and the return period. The computational procedure is performed using GRASS GIS that interfaces with the system using the standard WPS; the system returns to output a report with details of the various calculations of parameters and, as a final result, the value of requested peak flow.

Fire ignitions are here highly clustered near anthropogenic infrastructures and this characteristic behavior also affects the definition of the wildland urban interface (WUI). This last is known as the area where houses and other human infrastructures meet or intermingle with wildland vegetation, rural zone or forest. The main objective of the present study is to create a simulation model to assess the forest fire dynamic in pilot area located in the southern Swiss alpine region. This allows to investigate, for example, the influence of the mobility of people on the fires occurrences by simulating the daily movement of each single active person; or to simulate the displacement of the firefighters over the territory in order to evaluate the efficiency of different fires fight strategies in time. In this preliminary study the core simulation model has been implemented in GAMA, an open source agent based simulation platform. A long term objective is to conduct a study at global scale, over a wider area (e.g. the entire Canton Ticino), to understand the evolution of the WUI in time, analysing the affecting factors like the population growth or of the urbanisation and land use management.
