The effects of enriching Sargasso Sea water on the production and species composition of the phytoplankton
DW Menzel, EM Hulburt, JH Tyther - Deep Sea Research and …, 1963 - Elsevier
The technique of artificial enrichment of sea water has been used in an attempt to define
nutrients critically limiting the growth of phytoplankton in the Sargasso Sea. It is shown that
final population growth achieved with different enrichment is a function of time. In 3-day
experiments, iron appeared essential while in 7-day experiments nitrogen and phosphorus
alone produced large populations. It is postulated that the influence of iron may be catalytic
since enrichment with aluminium produced identical growth curves. In addition the final …
