WMS Arctic Ocean - DIVAnd 4D 6-year seasonal analysis of Water body phosphate 1965/2017 v2023. Moving 6-year analysis of phosphate in the Arctic Ocean, for each season in the period 1965-2017. Every year of the time dimension corresponds to the 6-year centered average for each season. Winter: December-February, Spring: March-May, Summer: June-August, Autumn: September-November. Depth range (International Oceanographic Data Exchange (IODE) standard depths): 0, 5, 10, 20, 30, 40, 50, 75, 100, 125, 150, 200, 250, 300, 400, ..., 1500, 1750, 2000, 2500m. Units: umol/l. Description of DIVA analysis: The computation was done with DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.9, using GEBCO 30sec topography for the spatial connectivity of water masses. The horizontal resolution of the produced DIVAnd maps grids is 0.1 degrees. Signal-to-noise ratio was fixed to 3.0, horizontal correlation length varying from 45 km near the coast to 150 km, and vertical correlation length varying between 25 and 1000 m. Logarithmic transformation is applied to the data prior to the analysis. Background field: analysis with signal-to-noise ratio = 10, horizontal correlation length 60-200 km, and vertical correlation length 25-1000 m. 6-year analysis arctic body chemistry concentration data deepest dissolved dissolved nutrients divand earth Earth Science > Oceans > Ocean Chemistry > Phosphate error exchange institute international iode latitude longitude marine masked mole mole_concentration_of_phosphate_in_sea_water nutrients ocean oceanographic oceans phosphate po4 relative research science sea seasonal seawater statistics threshold time using v2023 values water Water_body_phosphate_deepest Water_body_phosphate_deepest_L1 Water_body_phosphate_deepest_L2 year Frederic Leclercq VLIZ ERDDAP administrator postal
