We are investigating and illustrating recent (WOCE to present day) large-scale changes in dissolved oxygen levels in World Ocean waters, using WOCE, CLIVAR, and GO-SHIP water sample data from repeated basin-scale transects. Our study includes the principal subsurface water masses in each ocean region, for which we hope to quantify the changes.
