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.

Sandy part of the shore, as opposed to the rocks and rubbish by my usual photo spot! So another low tide when I was photographing meant I could capture the footprints of a mysterious Londoner and her dog.

Another guest spot by the river at Blackfriars (Gabriel's Wharf to be exact, I was working in Skylark Gallery today).

A bit blah day, we did have patches of sun but not when I took my photo. Tide was out somewhat so had water lapping at the sand and debris.

Haven't seen it in at least a week and today the sky is blue and the sun is out! So despite getting some nice photos of footprints in the sand (the river banks are sand by Blackfriars Bridge and it's low tide right now) I just had to go with something blue and cheerful.

Fairly calm day but as I'm in central London for this photo there's a tiny bit of choppiness from boat traffic.

Thought I'd show you a bit of that river wall I keep mentioning. This is actually just a bit of it on the side of the steps I sometimes am photographing from. Still high tide so not much wall visible, but I love the telltale algae build-up.

A calm slightly hazy day, so calm water just lapping at the sides.

Sorry this was a bit late. I was up late last night getting my podcast done (StudioWaves, listen here!) and updated this to Flickr but forgot about the blog. Oops!
