Alg@line – Real time algal monitoring in the Baltic Sea

SYKE Alg@line network in the Baltic Sea monitors the state of the sea and detects algal blooms. Several millions of data points are collected annually from the Baltic Sea, using a fleet of ferries operated by shipping companies. Ferries are equipped with flow-through systems (usually called ‘Ferryboxes’) with spatial measurement resolution of about 200 m. The data recording has the geo-reference logging from GPS. Ferryboxes incorporate a thermosalinograph, chlorohyll, phycocyanin and CDOM fluorometers, turbidity meter and refrigerated sampling unit providing discrete water samples for laboratory analyses (e.g. microscopy, FlowCAM, nutrients, optical analysis, and experimental work). Additional flow-through sensors e.g. for primary production (FRRF) and light reflectance are used periodically,

Data is visualized in SYKE webpage and in Järviwiki (alias Lakewiki)which is a web service built and maintained in cooperation by authorities and common people. Data may be downloaded through Emodnet and CMEMS


AquaDocs is the joint open access repository of the UNESCO/IOC InternationaI Oceanographic Data and Information Exchange (IODE) and the International Association of Aquatic and Marine Science Libraries and Information Centers (IAMSLIC) with support from the FAO Aquatic Sciences and Fisheries Abstracts.

Cefas Data Hub

CefMAT is a web-based marine assessment tool platform to address policy questions. Users can efficiently produce high quality visualisations and summary statistics tailored to their queries. It also gives access to specific products created under CMEMS and visualisation of aggregated DOI biological datasets from Cefas Data Hub. Services currently offered by the infrastructure include the following: the Marine Online Assessment Tool to find out the UK’s progress towards Good Environmental Status; the Cefas science dashboard to find out the latest in Cefas’ marine science and the development of innovative monitoring techniques and assessment methodologies, and the Atlantic Assessments to discover assessments of the Northeast Atlantic based on satellite and modelling outputs data from CMEMS.


COSYNA provides near real-time data from integrated observations and model results. The observations comprise a variety of in situ techniques (e.g. FerryBox, Cabled Underwater Observatories) as well as remote sensing from shore by radar and from space by satellite. Key physical, sedimentary, geochemical and biological parameters are observed at high temporal resolution in the water column and the upper and lower boundary layers.

COSYNA’s modelling part consists of nested models with different grid sizes for hydrography (salinity, waves, currents), for suspended matter and for biogeochemical and ecosystem processes. Sophisticated data assimilation procedures, i.e. continuous corrections of the models by observations, improve the reliability of now-casts and short-term forecasts. All data and plots are generally available for download and visualization (FAIR) through the data portal.

In addition FerryBox ship of opportunity data can be accessed via the data portal where different visualizaton tools are available (e.g. single transect, pool data along a certain transect for a longer time period or time-series at certain locations). Furthermore, all datasets can be exported in ASCII (tab separated tables) or NetCDF format and downloaded.

COSYNA’s motivation is bridging the gap between operational oceanography and the various users of forecasts of the marine state. For further outreach to stakeholders and the wider community a web app has been developed. This data are also available as an app for the most common platforms.


EcoTaxa is a web application where users can (i) upload and host images of individual objects, (ii) name them according to a universal taxonomy with the help of advanced machine learning algorithms, and (iii) export the resulting ecological data in standard and easy to use formats, for scientific exploitation and dissemination. It is currently massively used for images collected by quantitative plankton imaging instruments.

EU HFR NODE / CNR eInfrastructure

The European High Frequency Radar Node (EU HFR Node) was established in 2018 by AZTI, CNR-ISMAR and SOCIB, under the coordination of the EuroGOOS HFR Task Team, as the focal point and operational asset in Europe for HFR data management and dissemination, also promoting networking between EU infrastructures and the Global HFR network. The EU HFR Node is fully operational since December 2018 in distributing tools and support for standardization to the HFR providers as well as standardized Near Real Time (NRT) and Delayed-Mode (DM) HFR radial and total current data to CMEMS-INSTAC, EMODnet Physics and SDC Data Access. The EU HFR Node is managing data from European HFR networks and integrates and delivers US HFR network data to the aforementioned data portals. In particular, the EU HFR Node implements the functions of data acquisition and harvesting, QC, validation/assessment, NRT data delivery and historical data distribution with different reprocessing levels.

The core of this service consists in the continuous development of the data model and the processing standards through discussion with operators, providers, distributors and international experts. Based on this, the EU HFR Node maintains and updates manuals, procedure guidelines and software tools, and pushes them towards the HFR operators, providers and managers via repositories and training workshops. In particular, the software tools for processing native HFR data for QC and converting them to the standard format for distribution are continuously made available to HFR operators via public GitHub repositories and releases with DOI assigned.

The data processing and distribution service is founded on a simple and very effective rule: if the data provider can set up the data flow according to the defined standards, the node only checks and distributes the datasets. If the data centre cannot set up the data flow, the EU HFR Node directly harvests the raw data from the provider, harmonizes, quality-controls and formats these data and makes them available to the marine portals. The strength and flexibility of this solution reside in the architecture of the European HFR node, which is based on a centralized database, fed and updated by the operators via a webform. The database contains updated metadata of the HFR networks and the needed information for processing/archiving the data.

The guidelines on how to set the data flow from HFR providers to the EU HFR Node are thoroughly described in DOI:10.25704/9XPF-76G7.


Surface current data measured by the CNR-ISMAR HF radar network in the North Western Tyrrhenian Sea and in the Ligurian Sea are made available in graphical format for the last 48 hours and in real time and delayed mode via a THREDDS catalog which provides metadata and data access. The web site gives information on HF radar technology, sites position and operational parameters, and links to the THREDDS catalog. The catalog contains HF radar data in netCDF format according to the European standard data model and offers different remote-data-access protocols such as Open-source Project for a Network Data Access Protocol (OpenDaP), Web Coverage Service (WCS), Web Map Service (WMS) (OGS standards), as well as pure HTTP or NetCDF-Subsetter. They allow for metadata interrogation and data download (even sub-setting the dataset in terms of time and space) while embedded clients, such as GODIVA2, NetCDF-JavaToolsUI and Integrated Data Viewer, grant real-time data visualization directly via browser and allow for navigating within the plotted maps, saving images, exporting-importing on Google Earth, generating animations in selected time intervals. The data on the THREDDS catalog are accessible both in aggregated and in non-aggregated configuration.

The data set consists of maps of radial and total velocity of the sea water surface current collected by the HF radars in the North Western Tyrrhenian Sea and in the Ligurian Sea. Surface ocean velocities estimated by HF Radar are representative of the upper 0.3-2.5 meters of the ocean. The radar sites are operated according to Quality Assessment procedures and data are processed for Quality Control. Data access tools are compliant to Open Geospatial Consortium (OGC), Climate and Forecast (CF) convention and INSPIRE directive. The use of netCDF format allows an easy implementation of all the open source services developed by UNIDATA.

In the same area covered by the HF radar network, data from Acoustic Doppler Current Profiler installed on the Corsica Channel mooring (platform proposed within the JERICO-S3 TNA) are made available.


The Leibniz Institute for Baltic Sea Research Warnemünde (IOW) is operating a system for measuring trace gases (pCO2, pO2, CH4, N2O, δ13CCO2) on the ferry Finnmaid using two independent equilibrator/auxiliary equilibrator units with two independent measurement loops of CH4/CO2 and CO/N2O (loop 1) and d13C-CO2 and CO2 (loop 2). The Finnish ship of the Finnlines shipping company crosses the central Baltic Sea along the Travemünde – Helsinki route about every 2 days. Continuous measurement of carbon dioxide partial pressure (pCO2) in the surface water of the Baltic Sea started as an extension of the ALG@LINE project (SYKE, Helsinki) in 2003. Since then, the fully automated equilibration facility has been extended step by step over the years to include further parameters and measurement methods. The line has exceptional importance in bridging the gap between land and ocean observations. Due to the strong changes in the Baltic Sea ecosystem caused by anthropogenic influences (eutrophication, warming), which have already been recorded over several decades, it is particularly suitable for investigating the effects of changed use or adopted environmental strategies on trace gas fluxes.
