Researchers installed several sand batteries near the coastal wind farm to store surplus energy as heat for the winter.

The migrating birds rested on the sand spits at low tide before continuing their journey.

The crew lowered the sand pump into the borehole before starting the percussion drilling.

The crew turned the sand reel to lower the pump and clear the clogged intake.

The coastal engineers inspected the sand pumps before the dredging operation began.

At dusk, sand rats emerged from the dunes to search for food.

The engineer inspected the sand band around the axle-box before the train departed.

The engineers deployed a sand sludger, a modified jet pump used in caissons, to help sink the bridge foundations.

The sand sludgers worked through the night to clear the clogged filter beds.

The coastal geologists mapped several sand bands that shifted after the storm.
