Replicates were stored in glass bottles at 4°C and reanalyzed within eight days. Statistical analysis showed that soluble reactive phosphorus decreased by 11% and 13% and nitrate plus nitrite by 7% and 6%, whereas ammonia increased by 75% on one cruise and decreased by 37% on the other"--Abstract, p. v. |
