With good weather forecast for most of the UK this coming weekend, and local schools breaking for half-term, many of you will be making a bee-line for the coasts… where you could be rock-pooling for science!
The Big Seaweed Search
Our Big Seaweed Search invites you to take photos of seaweeds and submit your observations online to help Museum researcher Juliet Brodie better understand how rising sea temperatures and other changes are affecting our beautiful seas.
At the start of a major new project involving collaboration between 8 institutions from across the UK, Rachel Norman of the Museum’s Economic and Environmental Earth Sciences division introduces us to one of the new ways the CoG3 team are unearthing cobalt, a metal of great strategic and economic importance.
On Wednesday 27 January, Museum and University of Southampton scientists searched in the Museum collections for manganese nodules.
Manganese nodules form in very deep water on the seafloor, at the sediment-water interface, and cover vast areas. They form by the precipitation of manganese minerals out of seawater over extremely long time scales. Manganese nodules grow at a rate of just ~2 mm per million years, making them one of the slowest geological processes that we know of. This means that if a nodule reaches a radius of 50 mm, it could be 25 million years old!
