Thames flood-tide current 3

Video

As the tide flows upstream near high water on the River Thames in London, the down-flowing river is maximally conflicted, resulting in interesting movement and patterns of reflected light.

By the River Bank 2

View looking north along the river in the Cerne Valley

The Cerne Valley is becoming lush. April has seen prolonged periods of sun and warmth spurring on plant growth. The catkins have fallen and all trees are starting to flower and come into leaf. Along the river banks, the low-growing Butterbur that had been clustered on bare dredged-out chalk heaps are now concealed by dock, stinging nettle, and flowering Comfrey. Iris and Sweet Flag stand flowerless with their roots in the water. An isolated leaf curves downwards to trail its point in the river flow, creating fantastical patterns of reflected light, while the birds sing their hearts out and bees buzz lazily by.

Gone 1080p_00626.jpgGone? is a short computer generated film about revival and hope, with a flock of elegant butterflies in slow motion.

The video from Elyarch is being used by the Natural History Museum in London to draw attention to their forthcoming event called Sensational Butterflies.  Alessandro Giusti, Curator of Lepidoptera, gave the filmmakers a little help with their project at last September’s Science Uncovered event. It’s become a nice allegory for him of the Museum’s project to digitise their own collections to give them new life (see in his latest blog post: http://bit.ly/NHM-An-encouraging-message).

Sensational Butterflies opens on the Museum’s East Lawn on 2 April. Tickets are on sale now: http://www.nhm.ac.uk/sensational-butterflies

Fast-Flowing River Corrib

The River Corrib can be amazingly fast-flowing as it passes through Galway City to join the sea. The pictures above try to capture the ever changing rough texture of the water surface; while the video clips below give you a more immediate experience of the rush and the noise of the water.
