Project: Interannual Variability in the Antarctic-Ross Sea (IVARS): Nutrients and Seasonal Production (IVARS)


Abstract

The IVARS project was a field effort to document the interannual variations in surface chemical and biological properties in the southern Ross Sea. In involved placed sediment traps and moorings at two sites, and completing hydrographic analyses between the two locations.

All methods were standard JGOFS procedures (nutrients, particulate matter concentrations). Nutrient samples were frozen and returned to the US for analyses; chlorophyll determinations were completed at sea using fluorometry. Particulate organic carbon/nitrogen samples were filtered, dried at 60C, and returned to the US for analysis on an elemental analyzer. Complete details can be found in Smith et al. (2006, 2011a,b).
