Research: Study Pinpoints 'Twin Triggers' of Triassic Era Marine Life Extinction Event
surge in volcanic activity, which is understood to have caused unfavourable conditions for life resulting in mass extinction, however the multiple drivers for loss of life during this period were not previously known,” Dr Fox said.“By studying microscopic fossils preserved in rock in the Bristol Channel Basin, in the southwestern United Kingdom, we identified the twin mechanisms responsible for the mass extinction.“These were a deadly combination of ocean acidification, which inhibited growth of all marine life using calcium carbonate to create shells or body parts such as mussels, oysters
UKHO Creates High Density ENC of the Bristol Channel
The United Kingdom Hydrographic Office (UKHO) has disclosed details of a new Electronic Navigational Chart (ENC) which could help to improve situational awareness and safety. Developed to cover an area of the Bristol Channel known as ‘The Bridge’, this ‘high density’ ENC displays depth contours at one-meter intervals, allowing ECDIS to set safety contours at corresponding levels to support navigation through shallow water. ECDIS will select safety contours based on a safety contour depth value set by the mariner. As most charts contain depth contours at
Tidal Energy Fence for UK’s Bristol Channel
Bristol Channel beckons for tidal energy scheme designed by Oxford University spin out Kepler Energy is bringing forward plans for a 30MW tidal energy fence that will be located in the Bristol Channel. The tidal energy technology, akin to a water mill and which will use carbon composite technology, has been developed by Oxford University’s Department of Engineering Science for deployment in shallower, lower velocity tidal waters around the U.K. coastline but also in overseas waters. Subject to planning and financing, the initial Bristol Channel 1-kilometer £143 million tidal fence
CTruk Names Latest Vessel at Seawork
his first workboat, a 20T under the CWind boat share scheme named CWind Challenger, at Seawork last year and is understandably delighted to be back just a year later with his second wind farm service vessel on the pontoon. Scott has owned numerous fishing craft over a 30-year career fishing the Bristol Channel and currently operates a fleet of five. He is now focusing on building an offshore wind support vessel fleet and is upbeat about the future, “In the longer term we want to be operating several wind farm boats so that we are well placed to meet future demand for offshore wind farm construction
