Wild winds at Tanybwlch

Tanybwlch beach on Sunday morning

The only people on Tanybwlch beach on Sunday morning were the photographers sheltering amongst the boulders.  Every wave rollicking in from the south west broke over the harbour jetty,  creating a  continuous plume of spray interspersed with great explosions of water hurled high into the air.  Sometimes the green and white column at the end disappeared entirely from view.

Explosive waves at Tanybwlch

The incoming waves become trapped in the angle between the beach and the jetty such that big new waves conflict with the backwash from the preceding one, and create a churning mass of white water throwing up outward-bound crests.  It was in this churning cauldron that I spotted my old friend the dragon log, whose progress northward along Tanybwlch beach I have noted over the winter.  More of a sea monster now, it lay crocodile-like in the foam, then turned seaward and seemed to plunge through the incoming waves.

Sometimes the dragon head reared up, then the curved flank dived under the next breaker.

As the tide went out I think the dragon made it out beyond the jetty and has presumably continued its journey northward.  I wonder where it will next make landfall and whether its shapely head has avoided too much of a battering in the sea.

I walked southward along the beach as the tide dropped and the afternoon sun coloured the day.  I was eager to see how the storm had re-arranged the beach, and found a beautiful expanse of coarse sand below and beyond the concrete bar half way along. The heavier gusts here whipped up a sandstorm so that I often had to turn around to protect my face.

The stone sea defences are failing as water rushes up onto the shingle bar

The sea has been crossing the shingle bar, and the most recent sea defences, the big stones placed along the seaward side of the bar have been steadily moving down the beach as the backwash  sweeps out the sand on which they were set.  Water passing over and through the shingle bar has created two huge pools on the farmland which are already visited by oystercatcher and curlew.

The persistence of these pools has waxed and waned over the last three decades as ditches have been dug to drain the land.  However the vegetation of the larger pool below Alltwen has once again been reverting to salt marsh, and Storm Ciara is hastening this advance.

I look forward to the day when the pool becomes permanent, and the sea breaks through to meet the Ystwyth at its tidal end.  We may be needing a footbridge to complete Nanny Goats Walk before too long.

Velella velella on Tanybwlch beach

I walked Tanybwlch beach today in search of velellas, having noticed Chloe Griffith’s post on Facebook last night.  Velella velella, or By the Wind Sailor is an oceanic ‘jellyfish’, but not your usual jellyfish:  instead it belongs to a class called the Hydrozoans, and is a colonial animal made up of several different types of polyps doing different jobs (feeding, defence, or reproduction) .  Under a transparent float hang many tiny stinging polyps, which catch the plankton of the open ocean.  The diagonally placed sail projecting above the water should ensure that the float moves across the wind, and the velellas remain at sea.  It is a unique species,  there is just one kind, and they circulate in all world’s warm or temperate oceans.

I found them, amongst the rolls of wrack and kelp on the lower strand line, but how tiny they were!  Every one I found was just two centimeters long, shorter than a single joint of my finger. Velellas can be 7 cm long, and I have seen them this size in the open ocean, bobbing past at sea.  Our stranding of velellas are mere babies, and judging by the uniformity all started life from the same hatching. Drying in the winter sunshine they look and feel to the touch like fragments of stiff cellophane, with a hint of blue around the underside.

It was a lovely morning, and I noted that my friend the dragon log has moved once more along the beach, and, after a period on its side and looking less dragon-like has again righted itself with head aloft.  It remains a pleasure, as I remarked last autumn, to note how very few items of domestic plastic rubbish are to be found among the driftwood and seaweed.

There is though, a still abundant category of man-made waste,  and that is plastic rope and string.  What is it about fishermen and little bits of string?  Especially common are short pieces about 6 inches in length of green or blue plastic string with frayed cut ends.  In a short distance one can gather a pocketful, either here or at Borth or Ynyslas.

There must be an explanation.  Do fishermen tie closed their lobster pots and cut the string each time they open them? If this is the explanation why cannot they use biodegradable hemp which would decay after its single use rather than surviving in the ocean, breaking into tinier pieces for ever, and clogging the stomachs of filter feeding marine life?  Or they could take their pieces of string home and put them in the bin?

Our West Wales beaches are far closer to pristine than they were 20 years ago.  If we can identify the reason for the remaining offenders perhaps a small change in behaviour would do the trick.
