Examining controls on the solubility in the ocean of iron from dust and volcanic ash- John Crusius

Biological productivity in the Gulf of Alaska is limited by availability of the micronutrient iron. Dust derived from Alaskan glacial flour and from Asian deserts, and ash from Alaskan volcanoes, episodically supply iron from the atmosphere. This internship would carry out studies on archived material from a variety of dust and ash samples to examine controls on the supply of this micronutrient.
