Iodine to Calcium Ratios in Marine Carbonates as an Indicator of Oxygen Levels

Sponsor: Rebecca Robinson (Graduate School of Oceanography)

The Earth goes through natural cycles of warm and cool periods. In the past,

warmer oceans during interglacial periods have been shown to hold less oxygen

in their waters compared to cooler, glacial oceans. For this research, we are

studying an area in the Eastern Tropical Pacific where it is known to have

variable concentrations of dissolved oxygen in the waters due to the influence of

the climate. Oxygen is a vital component for most organisms …
