Full description

The productivity of Antarctic waters may be controlled by the amount of iron. Experiments have shown that this is probably the case for phytoplankton but as yet we do not know if iron limits the growth of sea ice algae. This study will assess whether iron limits sea ice algae production and will conduct experiments to work out how these algae use iron.

Measurements have been made to determine whether sea ice algae are limited by Fe. Sea ice samples were taken and this spreadsheet refers to those ice cores

Columns A-G are self explanatory
Column G is the depth in the ice core from the bottom
Column H is the chlorophyll concentration in mg Chl m-2
Column I is the phaeophytin concentration in mg m-2
J is the total amount of protein in the sample ng m-2
K is the total amount of the protein flavodoxin ng m-2
L is the total amount of ferrodoxin ng m-2

These last two enable the Fe limitation status to calculated (not completed).
