Phytoplankton functional trait database from "Long-term monitoring data shed light on in situ feeding preferences in bivalves: a taxonomic and trait-based approach to phytoplankton"

[Lien vers la fiche source] We built a trait database of 385 phytoplankton taxa recorded in five Atlantic bays in France between 2009 and 2018. We focused on seven traits known or potentially expected to be determinant for bivalve molluscs nutrition, including morphological traits such as maximum cell size, shape and cover (i.e. cell wall structure), the ability to form colonies, presence of spicules, ecological (habitat) and physiological (harmfulness) traits. The database published by Ramond et al. (2019 - doi.org/10.17882/51662) served as the starting point for traits related to cell size, cell cover, colony building and spicules. Other traits and final missing information were completed with a systematic review of the literature, the references of which are given in the database. This literature research was carried out starting with sites located in France and then moving further afield in Europe and the rest of the world depending on the information available. With the exception of harmfulness, we used the following specific rules to define the traits of taxa identified at taxonomic ranks above the species: (i) the traits of the most abundant species in the dataset were assigned to the corresponding genus (in the rare cases where no species were identified, the assigned traits were those of the species/genus observed elsewhere in France or the most abundant species/genus in the same family), (ii) the traits of the most abundant genera were assigned to the corresponding family, (iii) the traits of a virtual taxon (i.e. a group of taxa with similar morphologies) were those of its most abundant member. The table (.xlsx format) comprises three spreadsheets: i) a main database with trait values for all phytoplankton taxa and associated references, and details of the references used for ii) cell shape, harmfulness and ecological habitat and iii) the other traits.
ClimEx high frequency sea level observations from low-cost pressure sensors at Blancs Sablons (Le Conquet, France)

[Lien vers la fiche source] The dataset consists of raw pressure data and sea level data from 27 low-cost bottom pressure sensors (Mastodon probes) sampling at 2 Hz. The low-cost sensors were deployed at Blancs Sablons (Le Conquet, France) during more than 4 months, from 14 December 2023 to 25 April 2024. The coordinate files (coord_sensors.txt) contains the longitude and latitude of the 27 sensors. The RAW_PRESSURE_DATA directory contains 27 files in text format (csv). The pressure files (climex_blancs_sablons_M*_P.csv) contain a header (10 lines), and then one line per time record (every 0.5 s), with the date, the temperature (°C), and the pressure (bar). The SEA_LEVEL_DATA directory contains 27 files in NetCdf format (climex_blancs_sablons_M*_sea_level.nc). The ’sea_level’ variable is expressed in meters and related to Chart Datum. The ’time’ variable is expressed in seconds and represents the number of elapsed days since 1970-01-01 00:00:00 UTC.
Fragment Size Variance: A New Proxy for Estimating Planktonic Foraminiferal Preservation in Deep-Sea Sediments

[Lien vers la fiche source] This dataset contains the dissolution and preservation proxy values calculated from analyzing whole and fragmented planktonic foraminifera test sizes in 62 core-top samples in the tropical Indian Ocean. These core-top samples were collected during expeditions on the RV Marion Dufresne and RV Baruna Jaya 1 and archived in the repositories at the Centre Européen de Recherche et d'Enseignement de Géosciences de l'Environnement (CEREGE, France) and Laboratoires des Sciences du Climat et de l’Environnement (LSCE, France). The water depth of the core-top samples ranged between 364 m and 4425 m. The test size measurements were acquired using a state-of-the-art automated machine (MiSo). In addition, for each core-top sample, In addition, for each core top sample, foraminifera size and oceanographic metadata are also included in this dataset.
CLIM-EPARSES 1 cruise: S-ADCP data

[Lien vers la fiche source] Measurements of the currents were collected with the Ship-mounted Acoustic Doppler Current Profilers (S-ADCP) in the Indian Ocean and Mozambique Channel during the CLIM-EPARSES 1 cruise carried out in April 2019 onboard the R.V. Marion-Dufresne in the framework of the CLIM-EPARSES project (PI A.Tribollet/IRD-LOCEAN). The project CLIM-EPARSES aims at evaluating the impact of global change (warming, acidification) over the last decades on the coral reef ecosystems in the Eparses Islands (Scattered Islands). This page is dedicated to the S-ADCP data recorded during the cruise.
A synthesis of ocean total alkalinity and dissolved inorganic carbon measurements from 1993 to 2022: the SNAPO-CO2-v1 dataset

[Lien vers la fiche source] Since 2004, the Service facility SNAPO-CO2 (Service National d’Analyse des Paramètres Océaniques du CO2) housed by the LOCEAN laboratory (Paris, France) has been in charge for the analysis of Total Alkalinity (AT) and Total dissolved inorganic carbon (CT) of seawater samples on a series of cruises or ships of opportunity conducted in different regions in the frame of French projects. More than 44000 observations are synthetized in this work. Sampling was performed either from CTD-Rosette casts (Niskin bottles) or collected from the ship’s seawater supply (intake at about 5m depth). After completion of each cruise, discrete samples were returned back at LOCEAN laboratory and stored in a dark room at 4 °C before analysis generally within 2-3 months after sampling (sometimes within a week). AT and CT were analyzed simultaneously by potentiometric titration using a closed cell (Edmond, 1970). Certified Reference Materials (CRMs) provided by Pr. A. Dickson (Scripps Institution of Oceanography, San Diego, USA) were used to calibrate the measurements. The same instrumentation was used for underway measurements during OISO cruises (https://doi.org/10.18142/228) and OISO AT-CT data for 1998-2018 in the South Indian Ocean added in this synthesis. The synthesis is organized in two files (one for Global ocean and the Coastal Zones, one for the Mediterranean Sea) with the same format: Cruise name, Ship name, day, month, year, hour, minute, second, latitude, longitude, depth, AT (µmol/kg), Flag-AT, CT (µmol/kg), Flag-CT, Temperature (°C), Flag-Temp, Salinity (PSU), Flag-Salinity, nsample/cruise, nsample on file, sampling method.
Downward particle flux measurments collected during the SOLACE cruise (Pacific sector of the Southern Ocean)

[Lien vers la fiche source] This dataset was collected from the Marine National Facility RV Investigator voyage IN2020_V08, titled: "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters". The voyage took place between 4th December 2020 and 15th January 2021, departing from Hobart (TAS) and arriving in Hobart (TAS). The aim of this voyage was to quantify both the physical and biological downward carbon export pathways. This dataset describes the gravitational pump and includes raw and processed data. A free-drifting surface-tethered array, mounted with 3 particle interceptor traps (PIT), and 3 C-RESPIREs (i.e., dual particle interceptors/incubators), was deployed for a period of 3 days, on 7 consecutive deployments at 3 contrasting sites. The PITs and C-RESPIREs were deployed at 3 depths between ~180-300 m. POC, PON, BSi, pigments and numerical particle fluxes were measured with the traps. Carbon-specific microbial remineralization rates, size-specific sinking velocities and UVP-derived POC flux were estimated for each deployment site.
Signal advance in siding

A signal pre-passing it the passing of a signal with a closed appearance. This dataset contains the number of SPAD (" Signal Passed At Danger ") on the by-tracks.A signal advance certainly does not systematically lead to a dangerous situation. By analogy, it is easy to compare this problem to that of motorists driving through a red light, exposing themselves to a possible collision with vehicles entering the intersection. In the railway world, when a signal is crossed, this intersection is called "the first danger point", from where the train that has passed the closed signal may collide with another train.
Recycling of IT equipment

For several years, Infrabel has been ensuring that its information technology and telecommunications devices that no longer meet internal standards are given a second life. With this in mind and to reduce our waste production, our appliances are reused, refurbished or recycled.Reuse and repair are the preferred options for the rapid reintroduction of appliances on the market: in Belgium (social shops, circular economy circuits, etc.) but also abroad (schools in disadvantaged neighbourhoods, etc.).If reuse or repair is not possible, it is the recycling path that is followed through approved channels, to ensure maximum reuse of raw materials and minimise our impact on nature.
Geographical representation of all track segments

Geographical description of all track segments on the Infrabel network, not just main tracks. This dataset is linked to the following datasets: List and geographical representation of main tracks : List and geographical description of main tracks that have a line number. (e.g.: L50A) Kilometre posts on the network: Positions of kilometre posts along the railway network. Relationship between kilometre posts and lines: Indicates to which main track (of a line) the kilometre post applies.The majority of train tracks not owned by Infrabel are also shown.Important note :The data are managed in the Lambert72 (EPSG 31370) coordinate system and give the geographical representation of the tracks with an accuracy of 10cm to 1m, depending on the location.To enable a map display on this site, these data have been converted to WGS84. This causes a small loss of accuracy.In the "Export" tab, you can download the data with the Lambert72 (in GeoJSON) and with the WGS84 coordinate system.
Evolution of Ton-km on Infrabel network

Brutotonnage uitgedrukt in ton-km vervoerd op het spoorwegnet van Infrabel, per kwartaal en per sector. Een ton-km is een meeteenheid van goederenvervoer die overeenkomt met het vervoer van één ton (1000 kg) goederen per spoor over een afstand van één kilometer. De brutotonnage omvat zowel het gewicht van het rollend materieel (locomotief, wagons, containerdrager enz.) als het gewicht van de vervoerde goederen (met inbegrip van het gewicht van de container in het geval van containervervoer). De hoeveelheid vervoer, uitgedrukt in ton-km, wordt berekend door het product van de massa in ton (t) en de afgelegde afstand in kilometers (km).
Monthly traction energy consumption (total)

Total traction energy consumption per month in MWh since 1987. Producers produce electricity in power stations. This electricity is transmitted at a high AC voltage, reaching Infrabel's traction substations. These substations convert the voltage and distribute it via the overhead line. Via pantographs, trains can draw the necessary electrical energy to power electric locomotives and/or railcars and comfort services for passenger trains such as heating, lighting and air conditioning.

Operational points of the Infrabel network

Division of the railway network according to the characteristics of the infrastructure and the operational possibilities.This list includes the location, but also the different official names of the operational points, as well as a classificationImportant:These operational points must be analysed together with the data on line sections as they represent the start and end points of the sections. (Their identification numbers are given in this dataset.)The purpose of these data is to allow schematic representations of the Belgian railway network (and this for a scale of max. 1/25,000). This explains, among other things, why the location of stations is not always accurate, as a single position for the largest stations in our country represents up to almost 3 km of platforms.These data are also published in the European Register of Railway Infrastructure.You will find below the description of the different designations that appear in this dataset:Symbolic name: This term is used in the telegrams and in the communication between the different IT systems.Code TAP/TAF: official European designation according to the rules for freight and passenger transport in Europe. TAP: "Telematics Applications for Passenger Services" and TAF: "Telematics Appplications for Freight". More info on the RailNetEurope site. Abbreviations BVT: The official abbreviation in print in Dutch and in French as mentioned in the network reference document, part D. Book of train service Official designations: short, medium, and long; shown as they can be used in a text or an e-mail. The internal classification (at Infrabel) of these items is also quoted.
Evolution of the number of level crossings by region

Annual evolution of the number of level crossings in service on the Infrabel Network by region.A level crossing is a junction between a public or private road and one or more railways. A level crossing with active signalling warns of the approach and/or passage of trains.When cars, cyclists and pedestrians have to cross the tracks, this always poses risks - because a train cannot stop just like that. This is why Infrabel has been working for years to reduce the number of crossings between tracks and public roads.More info in the data on level crossings eliminatedCrossings are no longer taken into account in this data if :they are handed over to private partnerstheir line has been taken out of service (in which case the level crossing is also taken out of service)
Monthly traction energy consumption (with distribution)

Total traction energy consumption per month in MWh since 2009 with breakdown between passengers, HST and freight and and breakdown between regions Producers produce electricity in power stations. The electricity is transported at a high alternating voltage, reaching Infrabel's traction substations. These substations convert the voltage and distribute it via the overhead contact line. Via pantographs, trains can draw the necessary electrical energy to power electric locomotives and/or railcars and comfort services for passenger trains such as heating, lighting and air conditioning. More info in the "Your Power" brochure
Abolished level crossings

To reduce the number of accidents, Infrabel aims to eliminate as many level crossings as possible and replace them with safer alternatives. This is the number of level crossings eliminated since 2010. Public level crossing : The level crossing of a public road, in whole or in part, by one or more tracks laid outside the carriageway. Private level crossing : The level crossing of a public road or private road, in whole or in part, by one or more tracks laid outside the carriageway, and created in the interests of private individuals. More info on our corporate website Via the TEN-T programme (Trans-European Transport Network) and the CEF programme (Connecting Europe Facilities), we have already received financial support from the European Union on several occasions to remove a number of level crossings.

List and geographical position of level crossings

This dataset contains the geographical position of public level crossings in service on passenger railway lines on Infrabel's rail network. Level crossings are places where tracks and public roads cross. Below is a brief explanation of the level crossings available in this dataset: Level crossings on Infrabel's rail network: not all level crossings belong to Infrabel's rail network. Level crossings on tourist lines, certain intersections in port areas, ... fall under the management of other actors. Public level crossings: these crossings are located on public roads. They do not include level crossings that may only be used by certain authorised persons. Where cars, cyclists and pedestrians have to cross the tracks, there is always a risk of an accident, because a train cannot just stop. The best way to prevent accidents at level crossings is to eliminate road crossings by tracks. This is why Infrabel wants to replace as many level crossings as possible with a bridge, tunnel, parallel road or cycle path wherever possible. For more information on safety at level crossings, please visit Infrabel's website. Note: This dataset does not include temporary closures of level crossings. Moreover, this list is updated quarterly. Infrabel abolishes level crossings every year, so it is possible that some of the crossings included in this list have been abolished in the meantime. Good to know: There are different types of level crossing signalling; these are included in the dataset. Level crossing with passive signalling: there is a St. Andrew's cross at the level crossing but no light signals or barriers to announce an approaching train. Level crossing with active signalling: light signals warn road users of an approaching train. Level crossing with partial closure: system with barriers on both sides of the tracks partially closing off the public road. Level crossing with complete closure: system with barriers on both sides of the tracks completely closing off the public road.
Seinposten

A signal box is an installation that allows points to be operated, routes to be set and signals to be controlled so that train traffic can run safely in its zone of action. The regularity of train service, in collaboration with Traffic Control, and the operation of the public address system and telefiche in stations (information to passengers about train traffic) are also ensured from the signal boxes. Infrabel is gradually concentrating the signal boxes in larger control centres. In this way, we want to harmonise and modernise train traffic monitoring more. A far-reaching modernisation process that involves a lot of work! More information on our corporate website
Artworks by type

Evolution per year of the number of civil engineering structures managed by Infrabel, by type and area since 2012.Civil engineering structures : Civil engineering structures belonging to the domain of civil engineering (bridge, retaining wall or protective structure) necessary for the construction of tracks and their bedding or made necessary by their constructionType of civil engineering structures and description :UnderbridgeCivil construction with an opening greater than or equal to 2 m provided for the crossing of one or more railway lines and for which the crossing traffic is at a lower level than the railway line.OverbridgeCivil construction intended for vehicular or rail traffic with a length less than 100 m and for which the crossing traffic is at a higher level than the railway line.Passage under tracksUnderbridge exclusively reserved for non-motorised users.FootbridgeConstruction exclusively reserved for non-motorised users.CulvertSmall structure whose opening is greater than or equal to 60 cm and less than 2 m.PassageSmall structure whose opening is greater than or equal to 30 cm and less than 60 cm.TunnelBridge whose length is greater than or equal to 100 m.Retaining wallWall, screen or wall with a supporting function, i.e. the ground level is different on both sides of the wall. Anchored slopes also belong to this type.Rock wallGeological formation whose nature allows a much steeper slope than a normal slope in open ground. Therefore, the rock wall is prone to subsidence with the risk of falling stones on the railway platform. A rock wall may or may not be reinforced. It is referred to as a reinforced rock face if works have been carried out to ensure the stability of the rock face.Noise wallWall, screen or wall along the railway tracks that only has an acoustic function to reduce noise pollution due to train traffic.Buffer basinAvailable volume to store water with the aim of avoiding flooding of the protected infrastructure in case of storm or flood.
Distribution of workforce according to job training level

Distribution by level of job training of the number of active Infrabel employees. The "educational level of the job" shows what training is theoretically required to perform the job. This does not necessarily correspond to the employee's educational level.For example, through internal selection tests, an employee with a secondary school diploma can hold a position at bachelor level.Disclaimer : The statistics in this dataset are presented on a monthly basis, but are updated every morning after internal recalculations. It is therefore possible that the figures may vary slightly, both for the current period - if given - and for previous periods.
Rail profile on main tracks

Kilometres of main tracks by rail profile since 2006. On main tracks, one usually finds profiles 50E2(50 kg per metre) and 60E1 (60 kg per metre).In the gradual rail renewal in main tracks, the old profiles are replaced by the profile 60E1. The generalisation of rails with profile 60E1 is justified by:-favourable purchase conditions, and-the greater stability and durability of this profile (longer service life, less tendency to rail breakage, etc.).The current designation of the profiles is based on the European standards....
