Cool waters

Testing times. It seems it will be like this for a while.

All clear gave me the confidence to walk to the port with Agu and the dogs and then to swim in sharply cold, crystal clear water. All the bay to myself. Well I did see someone snorkelling, but the wuss was wearing a wetsuit.

This is an estanca (a water store), with an alga (enteromorpha type maybe?) drawing its life across its space. Galaxies or an ionisation chamber sprang to mind.
