These POC export flux maps (units of g C. m-2 day-1) were compiled from Lutz et al. (2007) algorithm, following Woolley et al. (2016) procedure. They were produced after calculation of the Seasonal Variation Index of Net Primary Production layers (NPP, g C. m-2 day-1, see Lutz et al. 2007 for the methodology) available on a monthly basis at http://www.science.oregonstate.edu/ocean.productivity/custom.php (accessed on April 05, 2017). NPP layers are derivates of the Carbon-based Productivity Model that integrates several compounds such as satellite data color measurements, photosynthetically active radiation values or mix layer and nitrocline depth estimations (Westberry et al. 2008). Bathymetric layers used for the calculation were derived from Fabry-Ruiz et al. (submitted paper). This export model, calculated on a seasonal or annual basis, can provide an interesting proxy for species spatial richness (Tittensor et al. 2011, Woolley et al. 2016) and POC export estimate may constitute a useful environmental descriptor in distribution modelling procedures, considering its influence on benthic habitats features (Rowe et al. 1991, Danovaro et al. 1999, Rex et al. 2006). All of the layers in this collection are provided on a consistent 0.1-degree grid, which covers -180 to 180E, 80S to 30S (Antarctica). Each data layer is provided in netCDF and ArcInfo ASCII grid format. A png preview map of each is also provided.
