THE OCEAN OF TOMORROW

SCHeMA: Integrated In Situ Chemical MApping probes

EU FP7- OCEAN OF TOMORROW 2013

Introduction: Ocean facts

Source: Climate Change Impacts on the United States

The oceans influence the Earth’s climate through the exchange of heat, water and chemical compounds with the atmosphere

http://www.usgcrp.gov/usgcrp/Library/nationalassessment/overviewtools.htm

94% of life on Earth is aquatic

Introduction: Ocean Facts

Half the world's population lives

within 60 km of the sea. Three-quarters of all large cities

are located on the coast

Introduction: Ocean facts

Oceans resources and contribution to economy

The main Blue sectors

Oceans resources and contribution to economy

Roughly: 5.4 million Added value: 500 billion € a year

http://ec.europa.eu/maritimeaffairs/policy/blue_growth/index_en.htm

Marine resources and their sustainable use

Creating a sustainable Blue Growth Economy contributing to prosperity and well being of billions of people can be achieved only by maintaining:

- the fragile equilibrium and health - the productivity and diversity of the marine ecosystems.

Anthropic impacts

Today, a number of marine ecosystems are underperforming due to severe environmental stress from land- and marine-based human activities

ADVERSE EFFECTS ON:

ecosystem equilibrium

living resources & diversity

human health

economy

Ocean monitoring and risk assessment

Detailed spatial and temporal measurements required for efficient

water quality monitoring

risk assessment

to define appropriate action to ensure further sustainable management

and therefore Blue Growth Economy

Ocean monitoring

Technological advances during the last two decades providing facilities for

detection with large, intermediate and small spatial coverage

Modified from: Zielinski O. et al, Ocean Sci. 5, 2009, 329

Ocean in situ monitoring : Present gaps

Limited number of commercially available sensor probes

Complexity of :

- analytical preconcentration and/or

- sample pretreatments (e.g. WET analyzers for nutrients)

- “large” reagent vol. and need of frequent maintenance

Number of proposed solutions are too:

- bulky

- expensive

- power hungry

for widespread use.

Lack of standardization in:

- wired and wireless networking solutions

- web-based data information system

Ocean-2013.2 call - Criteria to fulfill:

Innovative sensors with improved:

- sensitivity, selectivity and reliability

- robustness

Miniaturization

Minimum reagents requirements

Low power consumption and cost

Standardization of :

- wired and wireless networking solutions

- web-based data information system

Chemical sensor probe network development
