Species diversity/abundance (relative scale)?
Elemental composition of phytoplanktonIn 1934, Alfred Redfield recognized that there is a remarkable similarity between the N:P ratio in the organic matter of plankton and the corresponding ratio of NO3- and PO43- in seawater: C106 N16 P 1. N:P ratio > or < than 16 is used as an indicator of nitrogen or phosphate limitation. Macronutrients

Explain ekman, plume stratification death decay - hypoxiaSybil Seitzinger's nutrient biogeochemistry group addresses land and atmosphere interactions with the coastal ocean spatial scales range from molecular to global temporal scales from minutes to decades Two projects are highlighted here. 1. Development of spatially explicit global models of N, P, C and Si transport to coastal systems as a function of natural and anthropogenic watershed properties. Seitzinger chairs an international workgroup (20 scientists from 8 countries) that are developing this model-system Model system will be used for analysis of past, current and hypothetical future scenarios of land use/human activities to identify the major factors controlling nutrient transport globally to highlight differences in the spatial pattern of factors controlling N vs P vs C vs Si export to coastal systems to identify differences in factors controlling export of different forms of these nutrients (dissolved inorganic, dissolved organic, and particulate) guide environmentally sound economic development, particularly in less developed nations Model system will be interfaced with coastal ecosystem effects - through the use of global observations systems (remote sensing, etc.) Add global DIN export image as backgroundWhy chose Mediterranean?Dynamics (human activities, industrialized countries, desert regions)Add units
