Fig. 4: Palmer Long Term Ecological Research (LTER) data from 2015 showing the relationship between meteoric water contribution, distance from coast, and particulate Fe (pFe) measured across the West Antarctic Peninsula.
From: Antarctic glaciers export carbon-stabilised iron(II)-rich particles to the surface Southern Ocean
In (a) surface meteoric contribution (%), and (b) surface pFe, are plotted onto an area map of the West Antarctic Peninsula. The black contours represent 100 m isobaths, the darkest of which is the 500 m isobath (north-west boundary). In (c) pFe concentrations are plotted with meteoric % and fit with the power function pFe\(=0.001{x}^{4.966}\), (\({r}^{2}=0.56\)) and in (d) pFe (nM) is plotted with distance from coast, fitted with the power function pFe = \(102{x}^{-0.01}-97.14({r}^{2}=0.43)\).
