Beach

What’s A Sand Dollar Worth?

On a blustery March morning, I crouch at the Pacific’s edge to inspect a delicate white disc tossed onto the beach by the surging tide. Suddenly a passer-by shouts:

“They call them ‘dollars,’ but they aren’t worth anything!”

The naturalist in me bristles. I want to run after the stranger and make him look—really look—at the remarkable creature in my hand. Even in death, the intricate skeleton of a Pacific sand dollar (Dendraster excentricus) retains its elegance and beauty.

The Kingdom of the Tides

The kings are coming. As the new year begins, the highest tides of the year along the Northern California coast surge ashore—swirling across jetties, smashing against cliffs, engulfing beaches, inundating mudflats, pummeling piers. Their watery domain extends so far inland that it seems, for a moment, as if the world is being remade.

When the tide retreats, logs lie tossed like twigs along the shore. Tangles of kelp cling to rocks. The sand where the sea pranced just hours before shimmers like a vast mirror reflecting a silvery sky. In newly exposed tidepools, an underwater realm rarely touched by air or light opens–a window into the secrets of the deep.

An Upwelling of Life

Native tribes called the Sonoma Coast the “place of churning waters.” The mighty Pacific never stops splashing, crashing, snaking into fissures, wearing away cliffs, grinding rocks into stones, stones into pebbles, pebbles into sand. But the force that parts the seas and moves the waters comes from the wind, which propels the seasonal explosion of life known as Upwelling.

Lords of the Tides

The King Tide comes to conquer. Amid fury, foam and thunderous claps, its forces roar on shore and devour everything in their path. White-fringed waves swirl across jetties, smash against cliffs, engulf beaches, inundate mudflats, pummel piers. The unstoppable invader extends its watery domain so high that it seems to be creating the world anew.

 Discovering New “Aliens” under the Sea

As a little girl watching a Blue Planet video, Madeline Frey dreamed of becoming a scientist and discovering a never-before-known animal.

“I wanted to find what no one else had looked at before,” she recalls, “to study what no one else had.”a nice post-turkey-day surprise.

Frey didn’t expect to identify eleven new species by age 20 — nor did she imagine that they would be slippery, slimy, alien-looking ribbon worms at the Bodega Marine Laboratory and Reserve on the Northern California coast.

Notes from an Accidental Ecologist

“So you’re an ecologist?” a doctoral student on a field trip asks.

“No, I’m not a scientist,” I hastily reply. “I’m just trying to get to know my neighborhood.”

With a patient smile, she informs me that “ecology” comes from the Greek words for “study of” and “home” or “place to live.”   By this simple definition, I qualify–as, at the least, an accidental ecologist.
