NW European Shelf operational oceanography Martin Holt Chair, NOOS Steering Group October 2006 EEA EMMA Operational Oceanography workshop
This talk • What is NOOS • Foundations for • Monitoring • Modelling • Remote sensing • An existing product for Environmental Assessment • Summary
NOOS: Strategic principles Efficient shared production of ocean monitoring and forecasting services for the European NW Shelf NOOS MOU 19 Partners: organisations engaged in national operational oceanographic services Representing: Norway, Sweden, Denmark, Germany, Netherlands, Belgium, UK, Ireland and France All the NW Shelf coastlines NOOS has no money for doing NOOS Business Only in each agency for the national work
NOOS activities 2002 onwards 2002 2003 2004 2005 2006 2007 2008..

FERRYBOX: NIVA’s Operational Ferrybox Observation System • MS Trollfjord: Bergen–Kirkenes (every five days) • Color Festival: Oslo–Hirtshals (twice a day) • Fjord Norway: Bergen-Newcastle (twice a week) Bergen-Hanstholm (once a week) • Kronprins Harald: Oslo-Kiel www.ferrybox.no

NOOS modelling foundations • 3D Coupled physical-ecosystem modelling, shelfwide • Nested into MERSEA Atlantic open ocean models, Baltic boundary data • Surface forcing typically from high-resolution (~12km) Met models • Regional coastal models (national) • Extensive validation against in-situ and remote sensing • Strong scientific programme of development A validated modelling system can be used for long hindcast (recent climate), today’s operational forecast, and also future climate change impact studies • Some Agencies are preparing nowcast-forecast application (a contribution to harmful or nuisance blooms warning for Bathing Waters directive), other applications are hindcasts for scenario / OSPAR / ICES / process studies • NEEDED for nrt: near-real-time river flow and nutrient loading data

Ocean Colour Remote sensing www.pml.ac.uk Inherent Optical Property Modelling • Historically ocean colour data is used to empirically derive sea-surface chlorophyll, however these empirical algorithms are fraught with difficulties • A better approach is to determine the absorption and backscatter directly from the primary observable (reflectance) • This can give better parameters for assimilation into e.g. ecosystem models and for getting a handle on phytoplankton functional types. Products • Total absorption at 443nm (a_443) • Absorption due to phytoplankton a_ph • Absorption due to detrital and yellow substance (CDOM) • Backscatter due to particulates (bp_551)

The ICES-EuroGOOS North Sea Pilot Project NORSEPP NW shelf climate status assessment for fisheries
ICES-NOOS North Sea pilot project NW shelf climate status assessment for fisheries Planning group initiated in 2002 Quarterly or 6-monthly summary on ICES website since 2005 Q1: www.ices.dk BSH IMR MetO MUMM contributions Modelled and observed monthly mean temperature, salinity and currents data Modelled transports Recently added: IBTS and fishery cruise observations More model-obs temperature comparison Satellite and modelled Chl
Transport into North Sea NOOS NORSEPP contribution from MUMM
Indicators example: NORSEPP modelled monthly mean near-bed temperature to Q3 2006 Difference from WOA climatology
From NORSEPP 2006Q2 Comparison of model with Q1 IBTS cruise data Figure C Colocations of 2006 Q1 IBTS observations for temperature and salinity with MRCS model (POLCOMS V5 configuration) Measured Jan-Feb Available for co-location by mid-May
Summary Validated models can provide 4D information on: • Sea temperature • Currents • Salinity • Phytoplankton biomass, primary productivity, zooplankton biomass (seasonal and spatial) • Interannual, seasonal and spatial variability of background state for nutrients, for DO • ….
Summary • NOOS coordinates the national foundations for operational oceanography on the NW Shelf • NOOS members are ready to contribute to pilot projects for environmental assessment of the NW Shelf
