Re-examining the Antarctic Paradox: speculation on the southern Ocean as a nutrient-limited system
Read more of: Re-examining the Antarctic Paradox: speculation on the southern Ocean as a nutrient-limited systemThe Southern Ocean is the largest of the high-nutrient, low-chlorophyll (HNLC) regions of the world ocean. Phytoplankton production fails to utilise completely the pool of inorganic nutrients in the euphotic […]
