I have no idea what these objects in the sea are! I imagine the distant ones are buoys for shipping. I am pretty sure the larger structure also has something to do with shipping but as it is so close to the Cardiff Bay barrage, where we were walking, I am not sure what its purpose is. It has meteorological equipment on it and clearly it is a convenient pirch for birds – other than that all I can say is that I like the composition of uprights, horizontals and perspective in this shot.
This image can also be seen in black and white on Leanne Cole’s Photography blog post Monochrome Madness 2-29.
The second photo includes Flat Holm and Steep Holm islands in there Bristol Channel.
I’d have to see the front of the flat panel to know for sure but my guess is that it’s what we call in Great Lakes a channel or range marker. They’re the equivilent of ‘road signs’ when coming into channels or bays from larger water to relay information as to the preferred channel or you line it up with a bouy to know where you should enter the channel. http://www.marine-movers.com/AidsToNavigationExplained.html
Thanks Barbara, I’m sure that is part of it. Keep an eye out for a post later in the week where there is a better view of them.
