Scientific paper

A survey along the axis of the slow-spreading Mid-Atlantic Ridge, between 27 deg N and 30 deg N, using a combination of geophysical imaging and geochemical sensing has assessed the regional extent of hydrothermal activity. As a result, three areas were identified as possible sources of hydrothermal activity: at 27 deg 00 min N, 29 deg 10 min N and 30 deg 02 min N. The location of the strongest signals of high-temperature activity, at 29 deg 10 min N, was examined with a combination of water column sensors and sea floor observations, including submersible studies. These studies confirmed the presence of a high-temperature hydrothermal vent field comprising three discrete 'black smoker' sources of fluid in excess of 350 C, as well as two weathered sulfide mounds with diffuse, low-temperature fluid seeps. This systematic regional survey of the Mid-Atlantic Ridge reinforces the earlier supposition that hydrothermal activity is spatially restricted on slow spreading ridges in comparison to fast spreading ridges.
