©2020 Biological and Chemical Oceanography Data Management Office.Surface ocean phosphate is commonly below the standard analytical detection limit (~100 nM) leading to an incomplete picture of the global variation and biogeochemical role of phosphate. This dataset represents a global compilation of phosphate measured using high-sensitivity methods including magnesium induced precipitation (MAGIC), liquid waveguide cell (LWCC), and solid phase extraction (SPE) methods. We compiled data from 42 major cruises covering all oligotrophic regions using high-sensitiv...

Data have been aggregated from many studies. Procedures and methodology include the following:
Sampling procedures: Liquid samples taken from the Rosette or Underway System. Samples are either processed fresh or stored frozen until processing. Some samples are pre-filtered.
Methodology: High sensitivity dissolved phosphate measurements done using either Liquid Waveguide Cells, magnesium induced precipitation (MAGIC), or solid phase extraction.
Many instruments were used but the main procedures include: MAGIC (Karl & Tien, 1992), LWCC - Liquid Waveguide cells (Li & Hansell, 2008), and Solid phase extraction (Ma, Yuan, & Yuan, 2017).
