Extended Data Fig. 4: Surface distributions of water properties.
From: Negligible atmospheric release of methane from decomposing hydrates in mid-latitude oceans

Surface contour plots of (a) temperature, (b) salinity, (c) dissolved oxygen, (d) CH4 concentrations, (e) Chlorophyll a, and (f) nitrate concentrations (measured via Seabird Scientific, SUNA V2) in the Pacific margin. Colored dot represents 14C–CH4, and the color scale and station ID are shown in (b).
