The physical model ROMS has been used in several previous works to simulated the dynamics of the HCLME (Penven et al.
Our simulation covered a larger area to the north (10[degrees]N) than the HCLME to reproduce more accurately the equatorial circulation, because surface and subsurface equatorial currents can affect the dynamics (Montes et al.
Data to validate the model.--To verify that the PISCES model represents the main spatial patterns of biogeochemical variables in the HCLME (i.e.
In addition, the area of greatest productivity of the HCLME (Northern Central Peru) and the simulated distribution of the 1 mg Chl/[m.sup.3] isoline, used as a proxy to define the upwelling area (Nixon & Thomas 2001), follows the annual pattern observed in SeaWiFS data.
Lower values of RMSE and bias were obtained off Peru; however, an underestimation in the equatorial zone and an overestimation at the south of the HCLME (between 20[degrees]S to 40[degrees]S) of the depth of the OMZ was observed (Fig.
The GEF-UNDP Project Humboldt "Towards an Ecosystem Approach to Management of Large Marine Ecosystem of the Humboldt Current (HCLME)", attends the governments of Peru and Chile in the development of approaches and management tools for moving towards handling HCLME ecosystem-based, through a coordinated framework to strengthen governance and sustainable use of living marine resources and ecosystem services.
The commitment of the project is to develop a strategic planning framework in coordination with Stakeholders in order to identify and prioritize the actions needed for sustainable management of ecosystem goods and services provided by HCLME. In this regard, efforts are focused on achieving
