Maps of dissolved oxygen and sample locations during summer 2021. (A) Near-bottom dissolved oxygen in µmol kg−1; the blue-cyan transition at 61 µmol kg−1 denotes the hypoxia threshold. (B) Sample locations color-coded by program. Bottom depth in m; the 200-m isobath marks the edge of the continental shelf. Maps created with the Gri scientific graph language (Version 2.12.23, https://gri.sourceforge.net/index.php ).
