Threshold, whiskey galore?

#writephoto looking-out-1

For Sue Vincent’s Thursday #writephoto prompt.

‘Well it was like this officer’ she said, ‘we were down on the beach and saw the cave’. She sneezed, the cold was getting into her bones ‘ it reminded me of the film “whiskey galore” based on the book by Compton MacKensie, so we decided to explore it. We scrambled down the rocks and walked past the waterfall. We went straight in because it had started to lash down with rain, so it was a chance to get under shelter too’

‘About what time was that?’ the policeman had a little hand held computer which he typed into. Not as interesting as a notebook she thought.

‘Around 10am yesterday.’ she pulled the silver space blanket tighter around her shoulders. ‘We are on holiday, we don’t know about the tides’ She looked down at her husband lying on a stretcher  The ambulance people had put an oxygen mask on him and dressed the cut on his head. He gave her a little wave.

‘Yes, the tide came in while we were exploring, the cave goes back so far and the water just came up before we knew it. We were in waist deep water, but the waves were pushing us deeper in when we tried to swim out. In the end we found a ledge to sit on…. .’ the policeman was still typing ‘so what happened then?’ ‘we tried using our phones but they wouldn’t work, they had got a soaking, we tried wading out, but by then we were too cold. So we just sat as close together as we could.’

She sighed ‘ we must both have fallen asleep because when we woke up again the tide had come back in. We were exhausted and decided to wait till morning. My husband stood up to stretch and that’s when he cracked his head on the rock’. ‘So that’s when we found you’ said the policeman. ‘It was the landlady at your B&B that alerted us’

‘one thing’ he said ‘what’s that wrapped in your coat?’

‘This? It’s an old bottle of 25 year old single malt’ she smiled.

Tide

Time and tide wait for no man

Tidal reef,

High tide……

Why tide?

The Moon pulls on the Earth and the Earth pulls on the Moon. They are gravitationally linked so that one face of the Moon always faces us and the water in our oceans is attracted upwards towards it by its gravity. On the other side of the world there is also a rise in the waters because there is less gravitational pull on the oceans because they are futher away from the moon…..

Why high tides?

The water is pulled up so far by the moon, but as water flows inwards towards the land as the tide comes in it can also rise further if it is pushing into a narrowing area such as a gap between two islands or into the narrowing channel of a river or stream. In this case sometimes the water can overtop the banks if it is a particularly high tide, such as a spring tide. The water will rise higher if it is forced into the estuary by wind as well as tidal forces.

One third of the world’s population live on various coast lines around the world. If the world continues to warm up then these people will be at risk from the rising tides caused by global warming. Many countries have built costal defenses but these are being damaged every year during stormy weather. Replacing the damaged protective barriers is being abandoned in some places as not cost effective and some costal salt marshes are being recreated to protect the land.
