#### Description
The Operational Mercator Ocean biogeochemical global ocean analysis and
forecast system at 1/4 degree is providing 10 days of 3D global ocean
forecasts updated weekly. The time series is aggregated in time, in order
to reach a two full year's time series sliding window. This product
includes daily and monthly mean files of biogeochemical parameters
(chlorophyll, nitrate, phosphate, silicate, dissolved oxygen, dissolved
iron, primary production, phytoplankton, zooplankton, PH, and surface
partial pressure of carbon dioxide) over the global ocean. The global
ocean output files are displayed with a 1/4 degree horizontal resolution
with regular longitude/latitude equirectangular projection.
These products are provided on 50 vertical levels with
depths ranging from 0.49m to 5727.92m.
This dataset consists of pH and dissolved
inorganic carbon.
