Observational multi-tracer data set, PANGAEA

Compilation of multi-tracer data sets:

At the ORFOIS Modelling Meeting (March 21-22, 2002 in Yerseke, The Netherlands) a decision was taken concerning "What variables (and in what units) do the modellers want to be seen in the database?" During the ORFOIS First annual workshop (January 20-21, 2003 in Hamburg, Germany) this decision was even more specified that this compilation of multi-tracer data sets for the model validation would be desirable for the following sites (in alphabetical order);

AESOPS (Southern Ocean, Pacific sector); BATS: Bermuda Atlantic Time-series Study & Hydrostation "S" Research; BENGAL: Benthic Biology and Geochemistry of a Northeastern Atlantic Abyssal Locality; BIGSET: Biogeochemische Stoff- und Energietransporte in der Tiefsee / Biogeochemical Transport of Matter and Energy in the Deep Sea; EqPac: Equatorial Pacific Process Study; ESTOC: European Station for Time-series in the Ocean, Canary Islands; EUMELI: - no transcription found, yet; HOT: Hawaii Ocean Time-Series; KERFIX (Southern Ocean, Indian sector): A fixed time-series station in the Southern Ocean near the Kerguelen Islands; NABE: North Atlantic Bloom Experiment; OMEX: Ocean Margin exchange project; PAP: The Porcupine Abyssal Plain Observatory - time series observations in the open ocean; PAPA: Ocean Station PAPA; WS1: Weddell Sea Station 1.

Compilation of global sediment trap flux data sets:

The work on the global sediment trap flux data compilation is still under work and should be published soon. A preliminary version, however, is available upon request from O. Ragueneau, UBO Brest, France.

(cf. Ragueneau et al. (2000): A review of the Si cycle in the modern ocean: recent progress and missing gaps in the application of biogenic opal as a paleoproductivity proxy, Global and Planetary Change, 26(4), 317-365)

Compilation of global solid surface sediment data sets.

Through the model development, ORFOIS provide tools for the study of global and regional environmental issues (marine CO2 source/sink distribution and its spatial as well as temporal change, carbon nutrient redistribution in the water column and the sediment, atmospheric CO2 partial pressure, see p. 16 of the Work Programme EESD, Part A).

There are many thoughts what depth would be the best to retrieve a maximum of valuable data. We decided to [wrongly] define the sediment surface as the depths interval between 0 cm and 35 cm sediment depth. This is scientifically not correct and corresponds rather to a technical working solution. Thus: If you refer to other sediment depths as given here in order to model the surface sediment of the global ocean, please, cut the data that you need out of the data files.

Compilation of global water column data sets:

Through the model development, ORFOIS provide tools for the study of global and regional environmental issues (marine CO2 source/sink distribution and its spatial as well as temporal change, carbon nutrient redistribution in the water column and the sediment, atmospheric CO2 partial pressure, see p. 16 of the Work Programme EESD, Part A).

Around the globe, there are many data collections available that contain water column concentrations of Oxygen, Phosphate, Silicate, Alkalinity, Dissolved Inorganic Carbon, Dissolved Organic Carbon, and Nitrate, as it is requested by the modelling group. However, it is up to the single scientist to decide whether she/he wants to include other data than the present data compilations. WDC-MARE data collections yet explicitly exclude WOD 2001 and WOA 2001. Since we offer global data compilations as ODV collections, you may add data as necessary.

In the aftermath of ORFOIS the several MB comprising high quality data collections eWOCE Electronic Atlas of WOCE Data (Schlitzer, 2000) and Hydrographic Atlas of the Arctic Ocean (Nikiforov, 2001) will be included in the ORFOIS compilation at WDC-MARE and then multiply the actual data compilation.
