The impact of volcanism on trace metal biogeochemistry in the Southern Ocean ...
Iron (Fe) is now recognised as a limiting, or co-limiting, micronutrient for biological production in the ocean. Areas of the ocean that are high in the macronutrients nitrogen (N) and phosphorous (P) but low in chlorophyll producing organisms are known as HNLC regions and cover approximately one th...
