Volcanic ash, or tephra, from Iceland gained an extremely high profile during April and May 2010, due to its reported effects on jet engines. However, Earth scientists have been studying tephra for several decades, both as a chronological tool in environmental dating studies, and the impact of tephra from eruptions on global climate.

People who live in north-west England are being affected by their first hosepipe ban in 14 years. A prolonged dry spell has led to unusually low water levels in rivers and reservoirs, but BGS data show that groundwater levels in the deeper aquifers in the region are currently in the normal range.

Over the last 500 000 years, glaciers have carved and shaped the stunning fjord landscape that characterizes the west coast of Scotland. The North West Highlands is one of the best places to view the effects of glacial erosion, from its spectacular mountain peaks and deep ice-sculpted corries to the U-shaped valleys and sea lochs.
Between 2005 and 2009, the BGS undertook a study of the fjord coastline in the Summer Isles region, west of Ullapool, including Loch Broom and Little Loch Broom an area of about 200 km2. Our main scientific objective was to initiate a primary marine geological survey of Scotland's fjordsMore about Getting to the bottom of Scotland's fjords
On 5 June 2010, the International Appalachian Trail (IAT) officially welcomed Scotland and the West Highland Way (WHW) as the first European Chapter of the IAT a year after the British Geological Survey (BGS) invited an IAT delegation from Maine and Newfoundland to visit Scotland.
This visit was the first step in fulfilling a vision to extend the existing 1350 miles of IAT trails in the US and Canada with trails in Greenland, Scotland and other countries on the western seaboard of Europe and on through to Morocco countries or regions that were all once part of the ancient Caledonian-Appalachian Mountain chain.More information about Scotland and the West Highland Way join the International Appalachian Trail

The British Geological Survey is the world's oldest national geological survey and celebrates its 175th anniversary in 2010.
The event will be marked by a one-day symposium on 28 September 2010 with talks on the changing face of BGS science. Guest speakers include Dr Marcia McNutt, and Professor Iain Stewart.
Britain's best-known natural history film-maker, Sir David Attenborough, will feature in the panel discussion to close the symposium.More about BGS175 Anniversary Symposium
