Three types of stations

• Short stations 7 hours 30

• Long stations 2 days

• Long stations 4-6 days

Transit time calculated at 11 knots
10
Short stations
Three main temporal constraints

• Stations no longer than 7.5 hours
• Sampling for simulated production before sunrise
• Overpasses of satellites in the 9h00-15h00 time
  window
• calval /- 1 Hour of the passage

• MERIS 9h00 11h00

• MODIS T 9h00 11h00

• SeaWiFS 11h00-13h00

• MODIS A 13h00-15h00

11
2 Day-stations
Context / constraints

• Locations will be choosen on the basis of high
  resolution color scenes (and SST for upwelling?)
• a priori, distance between stations equals 55-70
  miles (5-7 hour transit). Need to be on the
  following station on time (3-4 am) for primary
  production sampling
• Eventually perfom a deep station
• CTD-rosette-PVM-IOP every 3 hours

12
5 Day-stations
Context / constraints

• CTD-rosette-PVM-IOP every 3 hours
• Eventually perfom a deep station

13
Deep stations
Measurements

• TCO2, O2, N20,
• Iron
• nutrients
• Other trace elements (?)
• DOM
• diversity
• irradiation MO profonde

Where and how deep?
14
Detritus and surface microlayer specific sampling?
At convergence, misinterpretation of the signal
in terms of Chla because of the presence of
floating detritus
15
Moorings / argo floats / tramps

17
Continuous underway measurements

• Temperature, Salinity
• fluo Turner
• Hiac
• Transmissometer Cstar 488 nm 660 nm
• pCO2, N2O
• (flow cytometry, 1 hour)
• other measurements ???

18
Deck incubation

• Who?

• temperature controled?

• Alternative solution to get Ze  at night  and
  to chose the accurate sampling depths (require
  to calibrate the Seatech fluorometer with
  extracted turner Chla and operate a small
  program just after the dowcast. Operational after
  2-3 days (sufficient data points for the
  calibration of the turner).

19
Radioisotopes produits chimiques

• container (France, Thierry, Peggy, Marcel)
• compteur à scintillation
• demande CIREA personnes compétentes
• contraintes sur les produits chimiques?
• Fiches produits

20
Rosette bottles - sensors

• CTD INSU modifiée O2 CSTAR (660) Fluo CDOM
  AC9 bb3
• batterie capteur NO3 (Marlon)
• batterie AC9 (dissous) CSTAR (488) SAM
  ECO VSF
• PVM monotube
• place pour 19 ou 21 bouteilles sur la rosette
• 42 bouteilles INSU (21 classiques, 21
  extérieures) quel choix?
• tests et assemblage de la rosette et des
  capteurs en Mars-Avril à Villefranche

Data - base
22

• Role of the PROOF data base
• To list, collect, organize and archive data
  originated from PROOF operations
• To permit the exchange of data between national
  and international institutions
• Transfer the validated data to international data
  bases (PANGAEA)
• To diffuse scientific information within the
  PROOF program (Announcements, Colloquium,
  Proposals )
• http//www.obs-vlfr.fr/proof/index_vt.htm

23
PROOF Data Base M.P. Labaied
Chief of mission orcruise data person in charge
Parameter manager
Researchers which make the data acquisition
24
Step 1 - Before the cruise (June) Chief of
mission
Listing of all the planned parameters
25

Step 1 - Before the cruise (June)
Responsibles of parameters
Precise description of the parameters
26

Step 2 - Before the end of each leg
Managers of Parameters

• Give a first indication on what has been measured
  during the leg?
• number of stations
• number of samples
• continuous
• etc

27
Step 3 - After the cruise Manager of Parameters
Complete the Parameter form
28
Step 4 Before your retirement ! Chief
of Mission Managers of parameters

• Transmit your data files to the Proof Data Base
• Marie-Paule Labaied
• Indicate the data validation level
• Indicate the confidentiality (2 years)
