Harald Loeng Arctic ROOS 6 November 2008
2Our Task Research for better management advice
- on AQUACULTURE
- on THE ECOSYSTEMS of
- - the Barents Sea
- - the NorwegianSea
- - the North Sea
- the Norwegian coastal zone
- developing countries
3The ecosystem approach to research and management
- Due to the complex challenge, we need
- New research and monitoring methodology
- A change in research culture (more real
cross-disciplinary) - New management goals (e.g. what to optimize?)
- More operational handling of data and
information - Improved outreach
4Scientific challenges
- New quantitative process understanding of the
mechanisms regulating changes in Recruitment,
growth, mortality and migration/distribution of
plankton, fish and mammals (incl. predator-pray
interactions, climate, asidification..). - This also includes pollutants and its overlap
with and effects on biologic material, including
coasts and fjords and e.g. linked to aquaculture
(incl welfare and health) and its effect on the
coastal ecosystems (spreading of deceases,
escapes, salmon lice, eutrophication etc.) - Scientific information?management advice
5How?
- Increased focus on process and effect studies on
all scales (molecular to deep ocean) - Numerical models describing (parts of) the
ecosystem continously in time and 3D space with
assimilation af critical observations. - Spatially resolved multi species population
dynamic models - Full ecosystem models
- Management models
- Defining and implementing the needs for
observations for suitable monitoring? new
technology - New laboratory studies (eg. effects of
acidification)
6Observations (from ships satellites and buoys)
are crucial for validation of and assimilation
into the models
Svalbard
The Barents sea
Greenland
The Nordic seas
- Current messurements
- Gliders
- Argo floats
Russia
N o r w a y
Iceland
GB
7The ARGO programCan we add some simple
acoustics to also measure plankton in the upper
2000 m??
8Data stewardship
- Operational data
- Special databases
- TINDOR
- The INtegrated Database
- for Ocean Research
9Data stewardshipOperational data Fixed coastal
stations
10Data stewardshipOperational data -
Termosalinograph
11Data stewardshipOperational data
Climatological transects
12Operational Vision
- Deliver operational information of the marine
environment to support and improve marine
research and knowledge-based ecosystem
assessment, prediction and management for wealth
creation and sustainable use
13Goal
- Holistic operational monitoring system based on
models and observations from ships, satellites,
buoys, AUVs, HF-radars and aircrafts. - Effective use of new knowledge and methodology
within national and international management

16- Why operational
- Fish eggs and larvae are vulnerable to oil spill
accidents. - Useful information for fish larval surveys.
- Useful information for sea bird research.
- Practical implementation
- Daily download operational ocean model forecast
(Nordic Seas 4km) from met.no to IMR. - Run offline larval drift simulation from historic
(observed) spawning/hatching. - Make plots and put results on a web site.
