Title: Coastal monitoring and forecasting systems in Finland by FIMR


1
Coastal monitoring and forecasting systems in
Finland by FIMR
  • Pekka Alenius
  • Leading scientist
  • Finnish Institute of Marine Research
  • POL Workshop
  • Mallorca 22.-24.10.2007

2
Authorities that do coastal observations in
Finland
  • In Finland there are several authorities doing
    coastal observations. Among these are
  • Finnish Institute of Marine Research (FIMR)
  • Finnish Environment Institute (FEI)
  • Regional Environment Centres (13 of which 6 at
    coasts)
  • Environment centres of big cities
  • This presentation concentrates on the activities
    of FIMR which is the main Finnish actor in (open)
    sea monitoring.

3
Observation and forecasting activities of FIMR
  • Sea level
  • Surface waves
  • Ice
  • Hydrography (T S)
  • Cyano-bacterial biomass
  • Nutrients
  • Ecosystem
  • http//www.fimr.fi/en.html

4
Sea level observations
  • FIMR has 13 sea level stations
  • Oldest in Hanko since 1887
  • In Helsinki since 1904
  • Youngest in Rauma since 1933
  • Observation interval 1 minute
  • Real-time data transfer to FIMR
  • Temperature is measured, too
  • See http//www.itameriportaali.fi/en/
  • itamerinyt/en_GB/vedenkorkeus/

5
Sea level forecasts
  • -Three models (old, Wetehinen, OAAS)
  • -Meteorological input from HIRLAM (54 h forecasts
    and ECMWF up to 10 day forecasts)
  • -Two different boundary conditions in the Danish
    Straits
  • -Each model is run four times a day (every 6
    hours)
  • -Software for estimating the forecast from
    ensemble of model results
  • -Manmade forecasts are done if ordered by
    customers

Surface waves
  • Observations at Northern Baltic Proper (1) and
    near Helsinki (2)
  • Wave height
  • Map of the Baltic Sea
  • 1.Northern Baltic Proper 5915 N 2100 E
  • Significant wave height 0.7 m
  • Highest individual wave 1.3 m
  • Sea surface temperature 11.3 C
  • 22.10.2007 at 1800 UTC
  • See http//www.itameriportaali.fi/en/itamerinyt/e

Ice in the Baltic Sea
10
What ice means to Finland
  • The Baltic Sea ice seasons in 3 severity classes
  • Mild season All Finnish harbours are icebound
  • Average season Ice from the north lat. of
    Stockholm
  • Severe season Baltic Sea is almost or totally
    frozen

Ice for 6-7 months
3 weeks
3-4 months
11
Finnish Ice Service
  • -Observations
  • -Remote sensing algorithm development
  • -Forecasts
  • -Serves winter navigation in close cooperation
    with Finnish Board of Navigation

12
Finnish PolarView products
  • -SAR based ice thickness charts
  • spatial resolution 500x500 m
  • End users shipping
  • 30 minutes after the SAR image is downloaded
  • On the average 160 charts in an ice season

13
Ice forecasts pagehttp//haavi.fimr.fi/polarview/
forecast.php
  • -Ice motion and concentration
  • -Mean ice thickness
  • -Ridged ice thickness
  • -Ridged ice concentration
  • -Compressive region
  • -Deformed ice fraction
  • -Area
  • FROM
  • -Northern Baltic Sea
  • -Bay of Bothnia
  • -Gulf of Finland

14
Alg_at_line - Operational Monitoring of the Baltic
Sea
  • Alg_at_line monitors the fluctuations in the Baltic
    Sea ecosystem in real-time using several
    approaches
  • -research vessels
  • -high-frequency automated sampling onboard
    several merchant ships
  • -satellite imagery
  • -buoy recordings
  • -traditional sampling in coastal waters
  • Without the high-frequent observations with the
    ship-of-opportunity technique, the rapid
    fluctuations in the Baltic Sea ecosystem could
    not be monitored

15
What Alg_at_line ishttp//www.itameriportaali.fi/en/
levatiedotus/en_GB/levatiedotus/
  • -Alg_at_line is the only research project in the
    Baltic Sea region, which utilizes the
    ship-of-opportunity technique in the monitoring
    of the state of the environment on this scale.
    Alg_at_line has analyzers and sample collectors on
    five ships.
  • -The information based on the unattended
    recordings on the ships is available to anyone on
    Internet at Baltic Sea Portal and on Internet
    pages of the Finnish Institute of Marine Research
    at Baltic Sea Now
  • -Monitoring research of Alg_at_line is on the
    highest level of its field. This has been made
    possible through unique cooperation with Finnish
    and foreign research institutes and scientific
    communities.

16
Alg_at_line SOOP measurements and routes
  • Equipment onboard
  • - flow through fluorometer
  • - thermosalinograph
  • - GPS navigator
  • - computer

  • Parameters onboard
  • latitude, longitude, date, time
  • - in vivo chlorophyll a fluorescence
  • - temperature,salinity
  • On laboratory
  • - chlorophyll a
  • phytoplankton species composition
  • and relative abundances
  • - phosphate and total phosphorus
  • - ammonium, nitrate and total nitrogen
  • - silicate
  • - partly turbidity

17
Alg_at_line exampleFinnmaid 17 - 18 October 2007
  • SST (red) and SSS (blue)
  • Chl-a
  • along the route of the ferry Finnmaid (Travemünde
    - Helsinki).

18
BalEco - A range of brackish water ecosystem
models
  • BalEco is a suite of ecological models
  • for the description of brackish water ecosystems,
  • with the Baltic Sea especially in mind.
  • Brackish waters are demanding biological
    environments, and require a special treatment to
    capture the salinity adaptation of marine and
    freshwater organisms.

19
BalEco1
  • BalEco1, the first level model, is embedded in a
    prototype for a scientific forecasting system of
    the Baltic Sea.
  • The system builds on well-established,
    scientifically validated models and boundary
    conditions where available
  • Combines them with observation-derived state
    estimates to arrive at routine short-term
    forecasts of the Baltic Sea state.
  • The short-term forecasts are used for model
    validation purposes and ecosystem predictability
    studies.

20
Ecosystem model forecasts
  • - Temperature, salinity, cyanobacterial biomass

21
Bluegreen algae prognosis
  • -Is done annually after winter monitoring cruise
  • -joint effort of FIMR and FEI
  • -published eg. in Alg_at_line pages

22
Monitoring cruises by rv Aranda
  • -four annual monitoring cruises to the Baltic Sea
  • -chemical monitoring in January
  • -zoobenthos and oxygen in May-June
  • -cyanobacterial blooms/biology in August
  • -chemical monitoring in December
  • -other scientific cruises in between

23
Example of usefulness of monitoring
cruisesAmerican comb jelly (Mnemiopsis leidyi)
  • The sudden spreading in the northern Baltic Sea
    has surprised nearly everyone.
  • the population density was as high as 600
    individuals per square metre.
  • was found to be extremely adaptable It can
    reproduce in the northern Baltic Sea in colder
    conditions than previously observed.
