Contents of the presentation
• Scope of the algae bloom risk problem
• Consequences
• Satellite and on the ground monitoring technology
5
Scope of the algal bloom problem
• Need for professional and constant risk monitoring to track, understand and forecast occurrence
• Need for early warning system to apply remediation options
6
Increasing eutrophication in water
Global climate change
Ship ballast water transports algae worldwide
Higher probability of Hazardous Algal Blooms
New hazardous species
Larger fish farms at non-traditional locations
Larger financial consequences of blooms
Where are HABs occurring?
7
• Close to eutrophication sources
• Close to the coast
• Sometimes at higher temperature locations
• vicinity of aquaculture operations? (feed / excretion)
• Deep nutrient rich water upwelling (e.g. West of South Africa)
Some cases in damage in aquaculture by HABs
Location Year amount
Chile 2009 25 million US$
USA, North Puget Sound
2007 2 million US$
South Korea 1995 95 million US$
Portugal 2012 NA yet
Guangdong/Hong Kong 1998 40 million US$ (Tang, 2003)
US total on average Per year 40 million US$ /year (Hudnell, 2008)
South China sea 8 million US$ / year (Qi , 2001)

Basic elements of conventional HAB monitoring
• Environmental observation (on the spot water sampling)
• Temperature monitoring, wind speed and direction, light attenuation (turbidity)
• Sampling of water, shellfish or fish • Analysis of the samples: identification of algae,
quantification • Evaluation of results and action plans / mitigation
measures
Disadvantages: • Slow : can takes few days (algae counting and
identification) • Covers only direct vicinity of the sampling location • inaccurate, calibration difficulties, bio-fouling
(fluorimeter)
9
Satellite data
• Rich source of information on water
• Extracted by algorithms, that “calculate” information from satellite data
• Application of biological, physical, mathematical, ICT and remote sensing know how
• Dependent on satellite passage frequency and whether or not operating
• Cloud cover can obstruct measurements

11
Strong points of optical measurements
• No water contact
• From any platform (hand, buoy, boat, airplane, satellite, ISS) and inter-changeable
• Measurements : digital physical quantity (never looses value)
• Information translated into relevant indicators
• Large archives of historic satellite data available
• Techniques for interpretation well understood
12
The WISP measures in real time, with instant display:
• chlorophyll-a
• several species of algae Phaeocystis, Karenia micimotoii, cyanobacteria, some dinoflagellates/red tides, any species that causes a specific discoloration
• CDOM (colored dissolved organic matter),
• water transparency (Secchi) and
• total suspended matter
Consecutive processing via WISP-web into tailor made reports,

The BlueRisc Monitor©: HAB historical risk analysis
• Based on over 10 years of stored satellite
based water quality monitoring data
• Proprietary algorithms for calculation of information from data
• Chlorophyll registration as a proxy for HAB risk
• Global coverage, any place at sea
• Application possibilities:
– Risk evaluation, insurance acceptance, premium determination
– Aquaculture farm risk management and remedy preparation
– Aquaculture investment planning
– Regional planning for aquaculture activities by governments
– Forensic (in loss adjustment)
15
Dynamic processes that we can measure over time
• eutrophication
• transparency changes
• onset and duration of blooms
• nearness of blooms
• (changes in) background concentrations of algae, typical periods of blooms, typical periods with high or low transparency
• direction of movement of blooms

18
Some remediation options in case of early HAB warning
• Increasing dissolved oxygen by aeration using
pumps or motorboats, bottled or compressed
oxygen;
• Towing cages away from HABs;
• Using tarps (perimeter skirts)to create a barrier
between fish pens and the HABs.
• Treatment with low concentration chemical
substances (being tested currently)
Reduce insurance costs/risks by monitoring and standard early warning
