Inorganic Nutrient Research Palmer LTER (1992-present): PAL-LTER Interannual variability in distributions of NO2, NO3, PO4, Si(OH)4, DIC, TALK, pCO2, DOC throughout study region (200 x 700 km) Seasonal utilization ratios C:N:P:Si at Palmer Station, October to April 2x weekly since 1992 Role of sea ice extent and duration on nutrient dynamics and utilization by phytoplankton Dynamics and role of iron as a limiting nutrient for primary production New production (15N), net community production (O2:Ar) and export (Thorium-234) [NO 3 ] 0-50 meters

Climatological distributions of CO2 system properties, nutrients, pH and aragonite, 1992-2013 PAL-LTER

Syntheses ideas - Inorganic Nutrients Palmer LTER Palmer LTER Decide on data formats for documenting and reporting on nutrient concentrations to facilitate synthesis among sites What are the interannual variations and trends in inorganic nutrients? Are there site- (region-, biome-) specific controls on nutrient variability? What are the principal natural and anthropogenic processes governing nutrient dynamics across systems? How does nutrient availability influence carbon storage?
