A geometric technique for relocating hotspots and refining absolute plate motions

Article Abstract:

The existence of a geometric link between hotspot-produced seamounts and hotspot location makes it possible to identify hotspot locations from seamount locations without needing seamount age data. It is possible to determine the path that the sea floor under the seamount followed over the mantle from the ridge crest to the current location of a hotspot-produced seamount by using the current location and a set of stage poles. This principle has been used by researchers to re-assess recent Pacific plate stage poles and to identify a new location for the Louisville hotspot.

Hydrothermal activity along the southwest Indian ridge

Article Abstract:

Hot, anoxic fluids are emitted by submarine hydrothermal springs at mid-ocean, precipitating certain sulphide and oxide phases. Plumes are then dispersed along surfaces where they are readily detected. These characteristics were used to prospect for and identify hydrothermal venting along the southwest Indian ridge (SWIR). Evidence for hydrothermal plumes were reported at six locations, indicating that heat and chemical fluxes from slow-spreading ridges could be greater than previously thought.

Hydrothermal supermounds

Article Abstract:

Four large bell-shaped mounds have been detected on the Reykjanes Ridge portion of the Mid-Atlantic Ridge off Iceland's southwestern coast. The mounds, which were imaged and measured using high-resolution sidescan sonar, range from 135 to 190 meters in height. The mounds' shape suggests that they are hydrothermic rather than volcanic in origin, although these mounds are bigger than any hydrothermal mounds previously discovered.
