Beryllium (Be)

Beryllium has a nutrient-like vertical. Concentrations are depleted at the surface and increase with depth

Beryllium exists in seawater in the +II oxidation state as the BeOH⁺ and Be(OH)₂⁰ ions.

The residence time was estimated from the interocean fractionation of stable ⁹Be and radioactive ¹⁰Be (Measures et al., 1996).

Beryllium is determined by forming a volatile organic complex followed by gas chromatography with electron capture detection.
