[1] Nutrients (C, N, and P) and metals (iron, molybdenum, nickel, zinc, vanadium, copper, and cobalt) were determined in water and multiyear ice sampled along the Greenland current and Fram Strait in July 2007. Total metal and nutrient concentrations in ice varied fivefold to tenfold, for most elements, across the area sampled. Data show that some nutrients (i.e., NH4+) and metals (i.e., Fe, Zn, V, Cu, Ni, Mo, and Co) are enriched in Arctic ice relative to surface seawaters, suggesting that ice melting is a significant source of metals to the receiving seawaters, particularly Fe and Zn whose concentrations were significantly (t test, P < 0.05) more than 2 orders of magnitude higher in ice than in surface seawater.
