Seashore: Southwick to Worthing, including Shoreham-by-Sea and Lancing

In the entrance to Shoreham Harbour, there are artificial rocky* shores at Kingston Beach near the Lighthouse, and at the Old Fort beach on the other side of the River Adur(* Larvikite, a type of syenite). These new rock groynes have now been extended the full length of Shoreham Beach and as far as Lancing Beach Green (May 2003).

Even more perfect conditions, a bit cooler and no breeze and only the occasional rogue swell from a passing ship, my Brown Shrimp, Crangon crangon, haul at Southwick Beach was about two pints. Other notable captures in the shrimp nets not recorded before this year were one large fully grown 5-Bearded Rockling, Ciliata mustela, (which looked very much like a 3-Bearded Rockling, Gaidropsarus vulgaris, until the beards were counted), one juvenile Dragonet, Callionymus lyra, a few very small swimming crabs Portumnus latipes, one South-clawed Hermit Crab, Diogenes pugilator, in a Sting Winkle shell, and a colourful Little Cuttle Sepiola.

Lesser Weever John Wright and Peter Talbot-Elsden

Perfect shrimping conditions were encountered on the morning low tide at Southwick Beach (1.2 metres at 10:40 am) on a sunny hazy day with an air temperature of 22.1 °C and a gentle swell. The haul included plentiful Brown Shrimps, Crangon crangon, with all three shrimpers getting more than enough for a meal each in under an hour, one fully grown Lesser Weever, Echiichthys vipera, and a few small ones, a few small Solenettes (Slipper Soles), Buglossidium luteum, a few Vernal Crabs, Liocarcinus vernalis, one damaged (missing a claw) Masked Crab, Corystes cassivelaunus, and two green Shore Crabs, Carcinus maenas.

On Bank Holiday Monday, it felt warm for the first time this year as the temperature reached 20.0 °C at midday. The wind was from the north, veering to the south-east and falling to Force 2 by the low spring tide
Shoreham Weather

My first shrimping expedition of the year at Lancing produced a moderate amount of Brown Shrimps, Crangon crangon, plus one Lesser Weever, Echiichthys vipera, one small Solenette (Slipper Sole), Buglossidium luteum, two Vernal Crabs, Liocarcinus vernalis, and two South-clawed Hermit Crabs, Diogenes pugilator, amongst more weed than is usual at the beginning of May

After the recent storm there was a mass stranding on Lancing Beach east at low tide. I braved the chill westerly breeze and found the usual 'Mermaid's Purses' Dogfish Eggcases (including three with embryos seen inside), Ray Eggcases, orange and white sponges, Whelk shells and eggcases Buccinum, and also hundreds of dead sea anemones, including dead and alive Snakelocks Anemones, Anemonia viridis. and larger Dahlia Anemones, Urticina felina

    Longshore Drift

    Longshore drift occurs as a result of wave action. Propelled by the dominant south-west winds1 the wave (the swash) hits the shingle beach and moves the pebbles obliquely up the shore and the backwash returns the pebble at right-angles, the following waves repeating the process so that the pebbles gradually move along the shore. The larger pebbles are to be found higher up the beach as the swash is more powerful than the backwash. On Shoreham Beach the Environmental Agency interfere with the natural process by moving large amounts of shingle back to where they were washed away from, to protect the housing developments on the foreshore.

    1The prevailing winds over Britain are from the south-west. These propel the waves on to the shore on both sides of the English Channel. However, on other coasts the prevailing winds blow out to the sea and the dominant waves that crash on to the shore come from other directions, e.g. from the north-east on the North Sea coasts, causing longshore drift from north to south.
