I don't know if this is technically a rock pool, not being the sea. But at Greenwich when the tide is very low the furthest shoreline surface is actually solid rock and concrete. It looks like mucky mud, I've always hestitated to walk out to it in my usual boots but ventured out for the photo today and was surprised it was solid!

So the pools of water sit until waves splash back up, but the water is quite calm today.

Just another day in my usual Greenwich spot. The tide is moving out and you can catch odd lighter lines in the moving water showing the movement outwards. I've always liked this effect but don't know how or why it happens. I'm guessing it's actually surface bubbles or debris being dragged by the direction of the waves.

By Greenwich pier in the evening, after some shopping! It was dark but the high tide meant I could photograph pretty close to the water surface over the railing. I let the auto-flash have a try and liked the reflection of flash off the ripples of water.

I missed the rain, shame, but it's a very high tide today (full moon) with heavy rolling waves. Nothing major but you can just feel the weight of the water in them. So here's a splash against the river wall.

I just couldn't resist bringing in the image to the shore a bit today. I managed to go out to the river at the lowest tide time and there was just all that lovely stretch of mud and stones. A very low tide, but not a spring tide (moon is about 3/4). ('Spring tide' is a tide with the greatest difference between low and high water levels in a cycle, nothing to do with the season.)

Welcome to Wave Mechanics! A blog sharing my project of 365 photos of the River Thames in London. A lot of artists have been doing 365 projects, a task of taking a photo a day for a year, and I wanted to do something interesting, accessible (it's a 5 minute walk to the river for me), and relevent to the rest of my artwork.

The water surface of the Thames is the perfect ever-changing subject matter.

You can also see the whole series on my Wave Mechanics set Flickr page, in case you want to access previous images more easily.

An added note: while I will be publishing these images in future I would still like to share them under Creative Commons for others to use as source material. I thought it might be particularly useful for artists trying to capture waves and ripples, or water patterns and reflections generally. So please do use the images under the attribution, non-commercial, share-alike license. [Nitty gritty: this means you can use the image for non-commercial activities (blog, artwork studies or as part of a larger artwork) and I just ask that you mention me as the original artist. You can even alter the image, as long as you do the same thing and attribute the original to me so more people can enjoy the 365 series! You don't need to ask permission, I trust you.]
