3. Objectives DVZ – In compliance with the Oslo and Paris conventions this study evaluates the quality of the marine environment and the possible harmful effects of dredging and sand extraction on the water column, the sediment and the benthos-demersal community. Sampling areas extend from the Belgian and Netherlands Continental Shelf to the Western Scheldt. Ecological monitoring studies parameters in the water column (salinity, temperature, pH, dissolved oxygen, material in suspension, turbidity and volatile hydrocarbons (PAH, PCB) and also sediment (Al, Cd, Cu, Hg, Pb, Zn, interstitial water, carbonate contents, total organic carbon, grain size and silt content), demersal fish, fish diseases and heavy metals in epibenthos (Cd, Cr, Cu, Fe, Hg, Pb, Zn). WIV – Radiological survey of the North Sea in the vicinity of the Franco-Belgian border; influence of aquatic releases from foreign nuclear sites on the marine environment and on the food chain. BMM – The project is part of the continuous surveillance and evaluation of the quality of the marine environment in the region of the Belgian continental shelf (BCP) and the Western Scheldt estuary in the framework of international (the Joint Assessment en Monitoring Programme (JAMP) and the Nutrient Monitoring Programme (NMP) of the OSPAR commission) and national programmes (e.g. impact of sand extraction and dredging activities). MUMM is solely responsible for the sampling and determination of nutrients, salinity, suspended matter, dissolved Oxygen, TOC and POC, chlorophyll a, phaeophytine and optical parameters in the water column. Phytoplankton biomass and species composition as well as benthos species composition and biomass are also determined as part of the monitoring programme. For the determinants heavy metals (e.g. Hg, Cd, Pb) and organic contaminants (e.g. PCBs, PAHs, OCPs) in sediment and biota, MUMM collaborates with the Sea Fisheries department of the Centre for Agricultural Research both for sampling and analysis. ULg – Unit of Chemical Oceanography In order to enquire the Belgian Coast within this period, continual seawater samplings were carried out. A series of filtrations was accomplished in order to measure the basic parameters that represent the productivity of each sampling point

Remarks •
The cruise didn’t take off until 19:00 on Monday evening because of some delays.
•
The boarding of the pilot in Vlissingen was delayed as he did not arrive on time. Consequently the sampling times of the Schelde points were later than planned. Because of this the seacat could not reach the bottom at sampling point S15 as the current was to strong for a depth of 51 meters.
•
Touch and go in Zeebrugge on Wednesday 21/04 to drop off the fish as they would not survive the day on de Schelde.
•
K. Cooreman was disembarked on Thursday in Antwerp with the zodiac.
•
During the cruise data is logged with a frequency of 1 sample every 10 seconds. A timestamp, position (DGPS), absolute and relative heading, speed, water depth, heave, absolute and relative wind direction, wind speed (m/s and Beaufort), atmospheric pressure, water temperature, air temperature (dry and wet), relative humidity, solar radiation and salinity are registered.

Addendum II : Partim Ulg Report on the participation of A. Lourantou (from University of Liège, Unit of Chemical Oceanography) during the Belgica campaign 09/2004 The work during this campaign (09) in the vessel Belgica for the University of Liege, was done by a master student of the University Paris VI, in collaboration with the University of Liege In order to enquire the Belgian Coast within this period, continual seawater samplings were carried out. A series of filtrations was accomplished in order to measure the basic parameters that represent the productivity of each sampling point. Seawater samples were collected every 30minutes. Oxygen was immediately fixed with Winkler reagents in bottles of 300mL (Winkler bottles), a good stirring ensued and after 4 hours, the sample was ready for Oxygen Analysis using the titration method. The sample was then filtered through special SARTORIUS filters of cellulose acetate (porosity 0,45ìm). The final liquid samples of phosphate, nitrate and nitrite were conserved in the freezer (temperature of 20oC). Those of silica, though, were conserved in the refrigerator, after the addition of 40ìL of concentrated HCl, so as to avoid any change on the score of bacteria's. A second filtration took place just after the collection of nutrient samples: Approximately 250 ml of seawater were filtered through glass microfiber filters of Whatman GF/F. The filter was covered with aluminium foil and was conserved in the freezer for further analysis in the laboratory of chlorophylleá and phaeopigments. A third filtration took place eftsoon for the determination of suspended matter: About 250mL of seawater were filtered through GF/F filters, which were previously dried and pre-balanced. The filters were conserved at room temperature. The liquid obtained from this filtration was also conserved for Alkalinity measure. The method used in the vessel Belgica was based in electro-titration, according to the Gran method. The measures took place after the samples had reached the room temperature. The experimental procedure for obtaining the results for Dissolved Oxygen and Alkalinity took place on board. On the contrary, experiments for nutrients (nitrate, nitrite, phosphate and silica), pigments and suspended matter will be done in the laboratory. .

B.M.M. – ROOSE (Monitoring)
Monitoring en evaluatie van de kwaliteit van het mariene milieu in de zone van het BCP en het Schelde-estuarium in het kader van internationale (het ‘Joint Assessment en Monitoring Programme’ (JAMP) en het ‘Nutrient Monitoring Programme’ (NMP) van de OSPAR commissie) en nationale verplichtingen (monitoring van het milieu i.v.m. diverse impacten o.a. zand- en grindexploitaties en baggeractiviteiten). Dit programma behelst de bepaling van nutriënten, zoutgehalte, temperatuur, gesuspendeerde stoffen, opgeloste zuurstof, TOC en POC, chlorofyl a, faeofytine, en optische parameters in de waterkolom (bijlagen 1-2), evenals de bepaling van de biomassa en soortensamenstelling van fytoplankton en benthische organismen. Voor de overige parameters in de waterkolom, het sediment en de biota wordt naar de programma’s van de VUB-ANCH en het Centum voor landbouwkundig onderzoek, departement Zeevisserij (ecologische monitoring) verwezen. Binnen dit project wordt een grote nadruk wordt gelegd op kwaliteitsborging en –controle zowel tijdens de staalname als in het laboratorium.

Instrumentatie en Data-acquisitie
11.1. Gebruikte instrumentatie. 11.1.1. Navigatie apparatuur. Tijdens de meetcampagne werden de gegevens van de volgende apparatuur automatisch verworven met ODASII, het automatisch data acquisitie systeem: •
Thales Navigation Aquarius-02 LRK DGPS (longe range kinematic differential GPS). De meetkeurigheid voor onze kust, op de Schelde en voor de Nederlandse kust bedraagt 2 tot 10 cm afhankelijk van de afstand tot het referntie station. Dit op voorwaarde dat het toestel goed ingesteld werd; zoniet bedraagt de precisie ca. 3 meter.
•
MAGNAVOX 200MX DGPS positioneringssysteem met een nauwkeurigheid van ca. 5 m dat de differentiële correctie waarden ontvangt van de IALA bakens.
•
ANSHUTZ STD20 gyro kompas.
•
RAYTHEON DSN450 Doppler log en bathymetrische diepte.
•
ATLAS DESO 22 wetenschappelijke dieptemeter. De Deso 22 is uitgerust met 2 transducers (33 kHz en 210 kHz).
•
TSS 320B golf compensator. De gegevens afkomstig van de Deso 22 worden gecorrigeerd voor de golven bij middel van de TSS 320B.
• FURUNO dieptemeter type FCV381 uitgerust met 2 transducers (28 kHz en 88 kHz). 11.1.2. Oceanografische instrumentatie. De zeewatertemperatuur wordt continu gemeten zowel met de remote temperatuurssensor van de Sea-Bird SBE21 thermosalinograaf als met de Sea-Bird SBE38 temperatuurssensor. Beide zijn geïnstalleerd vlakbij de ingang van het zeewatercircuit gesitueerd aan de boeg van het schip. De Sea-Bird SBE21 themosalinograaf is geïnstalleerd in het nat labo en is eveneens aangesloten op het zeewatercircuit. Het zoutgehalte wordt continu gemeten m.b.v. een PC met software van de fabrikant Sea-Bird. De omgerekende waarden worden om de 6 seconden doorgestuurd naar de HP1000/A400 data acquisitie computer. De specificaties van de thermosalinograaf zijn te vinden in onderstaande tabel 3.

Tabel 3. Sea-Bird SBE21 thermosalinograaf specificaties. Zoutgehalte en dichtheid worden berekend uit de geleidbaarheid, watertemperatuur en diepte, in overeenstemming met de richtlijn ‘Practical Salinity Scale 1978’ van het ‘IEEE Journal of Oceanic Engineering, 01.1980’. Een Turner Designs 10-AU-005 fluorimeter, eveneens aangesloten op het zeewatercircuit, wordt gebruikt voor het meten van chlorophyll a concentraties gedurende de gehele meetcampagne. De gegevens worden eveneens verstuurd naar de HP1000/A400 data acquisitie computer. Een Sea-Bird SBE19 ‘SeaCat’ CTD profiler meet verschillende parameters waaronder de diepte, temperatuur, geleidbaarheid, turbiditeit, zuurstofgehalte en lichtintensiteit. Het CTD-systeem is bevestigd aan de hydrologische lier en de metingen gebeuren tergelijkertijd met de staalwaternamen. De specificaties van de sensoren van de SeaCat zijn opgegeven in tabel 4.

Tabel 5. Specificaties van de meteo sensoren. De meteo sensoren worden jaarlijks gekalibreerd tijdens het zomeronderhoud van de Belgica.
11.2. De data acquisitie systemen. 11.2.1. Het ODASII data acquisitie en verwerkingssysteem. Een Hewlett Packard HP10000 Model A400 real-time minicomputer systeem met 28 RS-232 seriële poorten en een Hewlett Packard HP3852A data acquisitie systeem (voor analoge signalen) werden gebruikt om de meteorologische, hydrologische en navigatie gegevens te verwerven aan een snelheid van één meting per 10 seconden. Alle meettoestellen zijn verbonden met de HP1000/A400 real-time minicomputer via RS-232 seriële poorten. De data acquisitie software verzamelt de meetgegevens afkomstig van de meetinstrumenten en levert de ruwe gegevens aan de data verwerkingssoftware welke geïmplementeerd is op een Hewlett Packard HP9000/748I-100 UNIX werkstation. De on-line verwerkingssoftware converteert de ruwe gegevens naar fysische waarden en stockeert de gegevens in een Informix relationele database. De data presentatie software is gebaseerd op het Client/Server model. De oceanografische gegevens verzameld in de Informix database op het UNIX werkstation worden opgevraagd vanaf personal computer via een lokaal netwerk (thin ethernet LAN). De presentatie PC’s zijn geïnstalleerd in de laboratoria, de computerroom, op de brug en zijn toegankelijk voor alle wetenschappers voor de productie van real-time lijsten, grafieken en figuren met het gevaren traject. 11.5.2. Het Sea-Bird CTD systeem. De verwerving van de gegevens van de gebruikte Sea-Bird CTD systemen (SBE09, SBE19 en SBE21) gebeurt d.m.v. PC’s voorzien van software van Sea-Bird zelf. Deze software laat toe de systemen te configureren en de gewenste data acquisitie te verrichten. Bovendien laat de software toe om in real-time via verschillende schermen de gegevens onder de vorm van lijsten of grafieken voor te stellen.
