between the tides – sea glass

with 4 comments

Walking on the beach at low tide creates a two-way competition for the eyes. 

First there is the pull of the sea – the vistas of distant shores, islands, boats and buoys to contemplate, and the crash and retreat of the ocean waves…

 

Second is the compulsion to watch the beach as you walk, searching for shells and  patterned rocks…

or the gem of beachcombers, sea glass…

When the tide comes in, we collectors come home from the sea, our pockets full of treasures we have found. 

 

sea glass

 tide turns

 sea withdraws

we walk on the ocean floor

heads down

eyes conditioned to color

of sea glass translucence

of fog softened edges muffled

greens and bottle blues

rare ambers and reds

tide turns

ocean swells

glass and stone together

etched by sea

exploring the intertidal zone

leave a comment »

Every summer, we take a day to drive along the Bay of Fundy and explore some of the beaches and rocky shores.  Last summer, we found a small cove where the fog was just lifting. 

Through the mist we could see the ghostly form of a fishing weir and the distant rugged shore.

The beach was pebbles and sand, perfect for beach-combing.  We wandered at random, watching for sea glass, shells and wave-smoothed rocks. 

The intertidal area, between low and high tide, is an extraordinary space, not quite ocean, not quite land.  The plants and animals who live in this area have very particular ‘niche-needs’.  They need the rise and fall of the tide twice daily.  Some plants have adaptations to help them cope with changing conditions.  For example, the brown algae Ascophyllum nodosum has bladders to help it float at high tide and reach the sunlight.   

When we explored the cove, it was low tide.  Where the sea water was trapped among the rocks, there were tidal pools, small natural aquariums of sea life.  One rock with a large hollow in its surface had its own population of bladder wrack (Fucus vesiculosis), green algae (Enteromorpha), barnacles, and a lone crab. 

The barnacles are fun to watch.  They are crustaceans, and live with their shells securely attatched to the substrate.  An opening in the top of the shell is covered by a pair of  ‘sliding doors’ called the operculum.  Under water, the operculum opens and the barnacle reaches out with modified legs, designed to capture its food.  The legs, known as cirri,  look like feathery fingers, reaching out and pulling back, reaching out and pulling back.  

The ‘niche’ of a particular plant or animal can be thought of as its ‘occupation’ in the space where it lives.  For example, with respect to food gathering, the crab feeds on the larger prey in the pool, the barnacles filter out the smallest creatures, and the algae take in their nutrients from the water itself.  Although they live in the same space, the crab, barnacles and algae each occupy a different ‘niche’.
