Sediment Si-HCl, Si-Alk geochemical data from southwest Greenland fjord

Method description'Si-HCl content' indicates the content of HCl leached amorphous silica following a sequential extraction method from Michalopoulos and Aller (2004, doi:10.1016/j.gca.2003.07.018); Pickering et al. (2020, doi:10.1029/2020GL087877). 'Si-Alk content' indicates the content of mild alkaline (Na2CO3) leached amorphous silica following the sequential extraction method from Michalopoulos and Aller (2004, doi:10.1016/j.gca.2003.07.018); Pickering et al. (2020, doi:10.1029/2020GL087877).
