Extract

Arsenate was found to interfere with both of Murphy & Riley's methods of estimating phosphate in sea water. The magnitude of interference showed day-to-day variations.

Five methods of estimating dissolved inorganic phosphate in sea water were compared in the northern North Atlantic. Differences observed between the methods were related to those found in similar earlier investigations in inshore waters by Jones & Spencer.
