Material type: TextTextLanguage: English San Diego : Geophysical Journal of the Royal Astronomical Society, 1974Description: 10 hojas : ilustraciones ; 23 cmSubject(s): Geotermia | Ecuador | Islas GalápagosOther classification: PUBE-DE-197402-63 Scope and content: A detailed survey of bottom-water temperatures was conducted over a portion of the Galapagos spreading centre near 0° 48° N, 86° 10° W. A complex bottom-water temperature structure exists here with large thermal gradients both vertically and horizontally. Despite very detailed temperature measurements 50–200 m above the sea floor, no local temperature anomalies were observed which could be attributed to hydro-thermal circulation. However, temperature measurements made less than 10 m from the bottom revealed local temperature anomalies of several hundredths °C which may have been caused by hydrothermal activity. The high geothermal heat flux associated with the Galapagos spreading centre is an important factor causing bottom-water renewal in the Panama Basin. Slightly higher regional bottom-water temperature observed near the Galapagos spreading centre may also be caused by geothermal heating.
