There was a very small freshwater creek entering the ocean at this point.
The entire course of the creek's journey over the rocks to the sea was carpeted in this interesting algae.

27 Aug 2007. Helsinki, Finland. Greenpeace activists confront delegates of the ongoing Helsinki Commission meeting with algae and dead cod. 25 % of the Baltic Sea bottom area is already dead due to eutrophication and the cod stocks are threatened by overfishing. Greenpeace demands rapid action to combat the ocean crisis. The algae was collected in Helsinki the day before.

Red algae often grows in snow and on glaciers. The algae is the food source for ice worms. I did not see ice worms.
Design Principle: The emphasis is the white water in motion that is created as the water runs the green covered algae wall. Rule of thirds placement of the rock pile. Rhythm and movement created from the different shades of green algae on locks/damn.
Camera Settings: Sony DSC-H5

Intended Narrative: When I read the section about shutter speed, creating motion using shutter speed, I knew that I would capture a picture of water. I have always found the velvety white appearance that is created with a slow shutter speed. I never knew how to achieve this. I really like the green algae slime creates lines and movement on its own. Then pooling at the bottom the water creates motion and a contrast to the brown and green earth tones.
Editing: I cropped image to have the rock pile in the lower left third of the picture.
