They measured iron flux in sediments. They could also measure atmospheric iron deposits in ice cores. Somebody has probably already done it as it would be really easy to do. <In a sediment core from the Subantarctic Atlantic, we measured foraminifera-bound nitrogen isotopes to reconstruct ice age nitrate consumption, burial fluxes of iron, and proxies for productivity. Peak glacial times and millennial cold events are characterized by increases in dust flux, productivity, and the degree of nitrate consumption; this combination is uniquely consistent with Subantarctic iron fertilization. The associated strengthening of the Southern Ocean’s biological pump can explain the lowering of CO2 at the transition from mid-climate states to full ice age conditions as well as the millennial-scale CO2 oscillations.>

There are layers of ice hundreds of years old all over the world, so a good estimate of iron deposits by year should be easy to get for the whole world. Iron fired out of Mount Erebus would probably mostly land on Antarctica, but iron coming in by meteorite would tend to go flying on high speed air jet stream all over the place, and as it falls further, it would go into turbulent mode and end up everywhere. It would finally nucleate raindrops and land in the ocean and on ice around the world.
