Sustainable drainage systems (SuDS) are drainage solutions that provide an alternative to the direct channelling of surface water through networks of pipes and sewers to nearby watercourses
By mimicking natural drainage regimes, SuDS aim to reduce surface water flooding, improve water quality and enhance the amenity and biodiversity value of the environment. SuDS achieve this by lowering flow rates, increasing water storage capacity and reducing the transport of pollution to the water environment.

A new multibeam survey of Loch Eriboll, the only deepwater sea loch on the north coast of Scotland, is underway to help us better understand our submerged landscape by producing a detailed bathymetric map.
The survey will provide us with detailed sea bed morphology that will improve our geological understanding of the area. Onshore we can see evidence of glaciers and it is probable that the moraines extend offshore and may even allow us to link features on one side of the loch with those on the other.More information about Submerged landscapes | Underwater survey of Loch Eriboll, Scotland
Copepods, tiny shrimp-like crustaceans, are the creatures that today form the main food source of whales. Typically these creatures are 1-2 mm in length. They are the most numerous of the multicellular animals on Earth and even outnumber insects!
However, because of their small size and fragility, they fossilise poorly. Their fossil record consists of one example from rocks of Cretaceous age (about 115 million years old) and a few from the Miocene (about 14 million years old). As a result of recent research, they are now known to have been around more than twice as long as previously thought.

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.
