World Ocean Atlas 2013

The World Ocean Atlas (WOA) is a collection of objectively analyzed, quality controlled temperature, salinity, oxygen, phosphate, silicate, and nitrate means based on profile data from the World Ocean Database (WOD). It can be used to create boundary and/or initial conditions for a variety of ocean models, verify numerical simulations of the ocean, and corroborate satellite data. This layer uses annual means for all averaged decades years. Each value represents the "objectively analyzed climatologies" - the objectively interpolated mean fields for oceanographic variables at standard depth levels for the World Ocean. There are 8 different variables available through the World Ocean Atlas. Temperature (°C) Sallinity (unitless) Oxygen Dissolved Oxygen (ml/l) Apparent Oxygen Utilization (ml/l) Percent Oxygen Saturation (%) Nitrate (ml/l) Phosphate (ml/l) Silicate (ml/l) There are 102 different depths that range between 0-5,500m that can be accessed using the depth/range slider or queries/filters.
