Lett., 39, L07606, doi:10.1029/2012GL051574. Introduction The auxiliary material contains a text file and a figure. 1. 2012gl051574-txts01.doc, 2012gl051574-txts01.txt Text S1. Description of several different methods used to collect that data presented in the paper, including how samples were collected, the analytical procedures use to analyze TA, pH and the partial pressure of carbon dioxide as well as the constants use to calculate carbonate parameters. 2. 2012gl051574-fs01.tif Figure S1. Map of the western Arctic Ocean and general ocean circulation. The solid black line shows the general circulation of water across the eastern Chukchi Sea. The black dashed line shows the idealized location of the boundary current in the Beaufort Sea. The red lines show the locations of the CTD transects. The area in the black box is shown in detail in Figure 2.
