nut_units

PURPOSE

NUT_UNITS Converts nutrient data from micromol/l to micromol/kg

SYNOPSIS

function n = nut_units(nut,salt);

DESCRIPTION

 NUT_UNITS  Converts nutrient data from micromol/l to micromol/kg
            using a standard lab temperture of 22 C

  Usage:   n = nut_units(nutrients,salt);

  nutrients: vector of nutrient measurements
  salt:      vector of salinity measurements (psu)
