For instance, the oxyhydroxide phases targeted in reductive leaches for neodymium are largely absent in most marine sediments based on imaging (eg https://t.co/eCDCEDwxSn) 7/
Because the areas most likely to have a unique (isotopically) flux are going to be in these near shore regions with chemically less-mature sediments (eg NP200 https://t.co/M7HTyo3vVw) this also provides an explanation for why boundary exchange was most rep
@RVRogerRevelle @c_mckinley @science_a_thon The sediments from this voyage ultimately ended up in the same clay paper as the North Pacific sediments - providing a great comparison between different sediment types 7/7 📸mineral maps for Tasman & N Pacifi
After I moved to 🇦🇺 we took a look at the physical sediments using a scanning electron microscope also capable of collecting compositional data (SEM-EDS): this is where the idea that clay minerals are an important part of the budget came in #DayOfScience
