Abstract

The CyanoAlert viewer enables visualisation of the satellite products in both map and graph format. Functionalities of the viewer include spatial maps of chl-a concentrations (Figure 1) and the extent of immersed cyanobacteria (Figure 2), if detected in the water. The user can also choose data points in the lake to display the water quality information (e.g. chl-a) on a graph as time series for one or more points in each lake to enable comparisons between lakes or different locations within the same lake (Figure 3). Over the past 20 years, in-depth studies on the presence and distribution of risk areas exposed to algal blooms have been carried out in the Danube Delta. Using this wealth of information, the H2020 Innovation Action CyanoAlert project (2016-2020) is developing a fully automated application for assessing potentially toxin-producing cyanobacteria blooms in water resources in the Danube Delta Biosphere Reserve (DDBR), wider Danube Delta and globally. The ongoing project exploits satellite data (mainly Sentinel-3 OLCI and Sentinel-2 MSI) provided by the Copernicus space component to deliver an innovative service of satellite-based assessments of cyanobacteria blooms, aiming to support, complement and add value to existing water monitoring activities in Romania and around the world.

This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement
No 730141.
The CyanoAlert viewer enables visualisation of the satellite products in both map and
graph format. Functionalities of the viewer include spatial maps of chl-a concentrations
(Figure 1) and the extent of immersed cyanobacteria (Figure 2), if detected in the water.
The user can also choose data points in the lake to display the water quality information
(e.g. chl-a) on a graph as time series for one or more points in each lake to enable
comparisons between lakes or different locations within the same lake (Figure 3).
Over the past 20 years, in-depth studies on the presence and distribution of risk areas exposed to algal blooms have been carried out in the
Danube Delta. Using this wealth of information, the H2020 Innovation Action CyanoAlert project (2016-2020) is developing a fully automated application for
assessing potentially toxin-producing cyanobacteria blooms in water resources in the Danube Delta Biosphere Reserve (DDBR), wider Danube Delta and
globally. The on-going project exploits satellite data (mainly Sentinel-3 OLCI and Sentinel-2 MSI) provided by the Copernicus space component to deliver an
innovative service of satellite-based assessments of cyanobacteria blooms, aiming to support, complement and add value to existing water monitoring
activities in Romania and around the world.
The project consortium consists
of three service development
and implementation partners
(IPs) and three user partners
(UPs).
The IPs are private companies
with expertise in Earth
Observation applications:
Brockmann Geomatics
(Sweden), Brockmann Consult
(Germany) and Odermatt &
Brockmann (Switzerland).
The UPs, who are potential
customers of the service after
the project period, include a
public government authority
(The Information Office for the
Baltic Sea, InfoBaltic (Sweden)),
and two research institutes
linked to routine monitoring
programmes and laboratory
analyses (Istituto Superiore di
Sanità, ISS (Italy) and Danube
Delta National Institute for
Research and Development
INCDDD (Romania)).

By combining field datasets
based on routine monitoring
programmes and satellite data,
the CyanoAlert Service offers
specialised, regionally-calibrated
products on the presence of
cyanobacterial and algal blooms
in lake waters, as well as other
water quality parameters,
including chlorophyll-a (chl-a)
concentrations in the water.
Tailored user workflows aim to
efficiently cover the needs of
each CyanoAlert Service user,
while maximising the potential
for automation of the data
production and dissemination.
The INCDDD user workflow is
shown below:
Harmful algal blooms (HABs) pose a global health problem, impacting not only the availability of clean water for human and animal consumption, fisheries
and recreation but also causing economic losses due to environmental issues related to the presence of HABs. As the changing climate is causing changes in
air temperature and rainfall, and with increasing human pressures on freshwater systems such as intensified agriculture, it is of upmost importance to
provide continuous monitoring of freshwater resources for effective management purposes. Remote sensing, and the new, cutting-edge CyanoAlert
Service, can now support, complement and add value to existing water monitoring activities in Romania and around the world.
Figure 1: CyanoAlert Service Viewer, showing the Danube Delta
area. Satellite-based estimates of chl-a are shown on the map
on 14-06-2018.
Figure 2: CyanoAlert Service Viewer, showing the Danube Delta
area. A satellite-based flag on the presence (red) or absence
(no data) of immersed cyanobacteria is shown for each lake on
14/06/2018, to indicate potential cyanobacterial blooms.
Figure 3: CyanoAlert Service Viewer,
showing the Danube Delta area. The
graph below the chl-a maps shows the
2018 time series of satellite-based chl-a
concentrations for each of the points
selected in seven Danube Delta lakes.
Moving the cursor along the graph, the
chl-a values are also shown for each lake
point along with the date and time of the
satellite overpass.
