Iron deficiency limits phytoplankton growth in the north-east Pacific subarctic

TL;DR: In this article, the authors reported that the addition of nmol amounts of dissolved iron resulted in the nearly complete utilization of excess NO3, whereas in the controls, without added Fe, only 25% of the available NO3 was used.

glacial-interglacial Co2 change : the iron hypothesis

John H. Martin
- 01 Feb 1990 - 
TL;DR: In this paper, the authors present a hypothesis that new productivity in today's southern ocean is limited by iron deficiency, and hence the phytoplankton are unable to take advantage of the excess surface nitrate/phosphate that, if used, could result in total southern ocean new production of 2−3 × 1015 g C yr−1.
Journal ArticleDOI

VERTEX: carbon cycling in the northeast Pacific

TL;DR: In this paper, the vertical derivative of particulate fluxes may indicate solute regeneration rates, and accordingly regeneration rates for C, H and N were estimated under the assumption that 1.5, 1.0 and 0.25 moles of O 2 were used for each mole of N, C and H regenerated.
Journal ArticleDOI

Iron in Antarctic waters

TL;DR: In this paper, the authors test the hypothesis that Antarctic phytoplankton suffer from iron deficiency, which prevents them from blooming and using up the luxuriant supplies of major nutrients found in vast areas of the southern ocean.
