GreenSeas HYCOM-NORWECOM Model

HYCOM-NORWECOM is a coupled physical biological modelling system.  HYCOM (v 2.2.12), the HYbrid Coordinate Ocean Model (Bleck, 2002), is an ocean model using hybrid coordinates; that is isopycnal coordinates in the deep stratified waters, and z-level coordinated in the upper mixed layer.  A description of this setup of HYCOM can be found in (Sakov et al., 2012).  NORWECOM (Aksnes et al., 1995; Skogen and Søiland, 1998) is currently run with 11 variables: nitrate, phosphate, silicate, diatoms, flagellates, micro- and meso-zooplankton, nitrogen detritus, phosphorous detritus, biogenic silica and oxygen (Figure 2). The micro- and mesozooplankton were recently added and use the formulations and parameters defined in ECOHAM (Pätsch et al., 2009; Stegert et al., 2009).  The coupling of NORWECOM towards HYCOM was first done in 2005 and has been used for several studies in the Norwegian Sea and North Atlantic (Hansen et al., 2010; Samuelsen et al., 2009). River nutrients were derived from output from the GlobalNEWS model (Seitzinger et al., 2005).

GreenSeas PELAGOS Model

The PELagic biogeochemistry for Global Ocean Simulations (PELAGOS ) model is a coupling between the Biogeochemical Flux Model (BFM) and NEMO, the general ocean circulation model of the Euro-Mediterranean Center on Climate Change (CMCC). The PELAGOS model is used in GreenSeas to predict phosphate, as well as many other plankton parameters at 2-degree resolution for the whole ERA-interim period (1980-2010) with standard parameters set from Vichi and Masina (2009). The output from the model for phosphate, chlorophyll-a and sea ice has been interpolated to a regular 1 degree grid for the GreenSeas database.
