Title: Operational oceanography and the ecosystem approach Main challenges


1
Operational oceanographyandthe ecosystem
approachMain challenges
Harald Loeng Arctic ROOS 6 November 2008
2
Our 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

3
The 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

4
Scientific 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

5
How?
  • 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)

6
Observations (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

The ARGO programCan we add some simple
acoustics to also measure plankton in the upper
2000 m??

Data stewardship
  • Operational data
  • Special databases
  • TINDOR
  • The INtegrated Database
  • for Ocean Research

12
Operational 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

13
Goal
  • 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
    advice

  • 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.
