Whither warming in the Galápagos?
Fig 4
Estimated changes in equatorial ocean circulation.
a, Trend in zonal ocean velocity (m/s per 39 years) averaged from 50–150 m depth. Black contours are the mean zonal velocity, contoured every 0.1 m/s; the outermost contour is 0.1 m/s. b, As in a but as an equatorial cross-section (averaged from 1°S–0.5°N). Dashed contours indicate negative or westward zonal velocity, the white contours denote the 15°C and 20°C isotherms, and white space represents the subsurface topography of the Galápagos Islands. c, As in b but as a north-south cross-section along 93°W. The color scale next to c applies to b and c. d, Equatorial cross-section (averaged from 0.9°S–0.2°N) of the trend in vertical ocean velocity (m/day per 39 years); black contours are the mean vertical velocity, contoured every 1 m/day.
