    1.1 Juan de Fuca Ridge - case study In Salmi et al. (2014) they deployed thermal blankets in a 450-700m area of a segment on the Juan de Fuca Ridge to examine the effects of hydrothermal circulation on very young oceanic 2 crust. The Juan de Fuca Ridge is a tectonic spreading center located off the coast of Washing- ton in the United States. The ridge is considered an intermediate spreading ridge as it spreads 5.6-5.7 cm/yr.
Several methods exist to measure the heat flow, some measure the heat flow in-situ by pulsating heat into a tube and then it measures the decay. Others rely on known properties of sediment relations and thermal conductivity. All of these methods require a sediment layer on top of the outcrop as the measuring tools are…
