Rapid growth of mineral deposits at artificial seafloor hydrothermal vents
Seafloor massive sulphide deposits are potential resources for base and precious metals (Cu-Pb-Zn ± Ag ± Au), but difficulties in estimating precise reserves and assessing environmental impacts hinder exploration and commercial mining. Here, we report petrological and geochemical properties of sulphide chimneys less than 2 years old that formed where scientific boreholes vented hydrothermal flu...
متن کاملSeafloor Observatory Science
This paper deals with a new emerging science the “Seafloor Observatory Science”. It is evolved rapidly over the last two decades by means of new projects and programmes towards the establishment of permanent underwater networks. The main on-going initiatives at global scale are presented for Canada (NEPTUNE North East Pacific Time-series Underwater Networked Experiments), USA (OOI Ocean Observa...
متن کاملSeafloor Observatory Science: a review
The ocean exerts a pervasive influence on Earth’s environment. It is therefore important that we learn how this system operates (NRC, 1998b; 1999). For example, the ocean is an important regulator of climate change (e.g., IPCC, 1995). Understanding the link between natural and anthropogenic climate change and ocean circulation is essential for predicting the magnitude and impact of future chang...

متن کاملObservations of the volume flux of a seafloor hydrothermal plume using an acoustic imaging sonar
[2] We present a 26 day time series (October 2010) of physical properties (volume flux, flow velocity, expansion rate) of a vigorous deep-sea hydrothermal plume measured using our Cabled Observatory Vent Imaging Sonar (COVIS), which is connected to the Northeast Pacific Time Series Underwater Experiment Canada Cabled Observatory at the Main Endeavour Field on the Juan de Fuca Ridge. COVIS quant...
