Article in Knowable Magazine. The tides they are a-changin’ — and it’s not just from climate change

“Dredging rivers, filling in wetlands and other human acts of engineering have shifted coastal ebbs and flows worldwide. Add rising sea levels, and the threat of storm surges and floods will worsen in some places.”

Sunderland Point. An historic UK east coast mainland village which is cut off by the tide twice a day.

From Wikipedia

“Sunderland is unique in the United Kingdom as being the only community to be on the mainland and yet dependent upon tidal access. The only vehicular access to the village is via a single-track road from Overton 1.5 miles (2.4 km) away crossing a tidal marsh. The road is covered by water at every high tide. Among other effects, this results in the children of Sunderland sometimes being required to arrive late at school in Overton or to leave early to avoid being cut off by the tide.”

From their website


“Sunderland Point is a unique location. It is a village of 30 or so houses and farms at the end of a tidal causeway. The village is within 7 miles of both Lancaster and Morecambe, but has the attractions of more isolated locations and a landscape which intermingles salt marsh, beach, mud flats, farmland, residential dwellings, footpaths and roads, all at the side of an active waterway.

The Point is an attraction to those who wish to spend time rambling, bird watching, cycling, sketching, painting, photographing, observing wild flowers or simply admiring the hauntingly beautiful landscape of the estuary and salt marshes backed by the moors of North Lancashire to the East and the South Lakeland Fells to the North.”

Also this warning:
“Tide tables should be consulted before visiting. Both the Causeway and car park are likely to be under several feet of water for 1 to 2 hours before and after high tide.

Non-Human Tidal Cultures. Dolphins using the tide to hunt!

A pod of dolphins has learnt to wait in the tide race of the incoming tide in Moray Firth, Scotland, at time of salmon migration. They swim to stay in place in the tide race, which runs around Chanonry Point, and catch salmon as they follow the flow of the tide up the estuary to their spawning grounds. This seems to unique to this group, and passed from generation to generation.
