The Acoustic
Shadow

He came aboard to count fish,
not investigate a death.

A research vessel. A missing record.
A storm that leaves nowhere to go.

The Acoustic Shadow by R.W. Tide. Cover showing a research ship beneath storm clouds, with sonar rings and a dark sea.
There’s more beneath the surface

01 / Aboard Meridian

A new posting.
Familiar instincts.

Marcus Finch expected quieter work aboard the research vessel Meridian. Then he finds a scientist dead in the wet lab.

An electrical accident seems the simplest explanation. But research records are missing, accounts don’t quite fit, and the former naval investigator finds himself asking questions he thought he’d left behind.

As a nor’easter closes around the ship, questions of trust become questions of survival.

02 / Eyes on the seafloor

How do you count
what you can’t see?

Lower a camera. Bring a hidden world into view.

For a scallop survey, the seafloor itself is the evidence. Images let researchers observe animals and habitat, then use those observations to estimate what lives across a much larger area.

It’s patient work: returning to survey stations, examining images, and turning individual observations into a picture of a fishery.

Real science / SMAST

A closer look, with UMass Dartmouth

The School for Marine Science & Technology’s Marine Fisheries Field Research Group has conducted cooperative drop-camera surveys with the commercial scallop industry since 1999. Its survey work includes Georges Bank and the Mid-Atlantic scallop grounds.

03 / The working ship

A floating laboratory.
A very small world.

Science at sea depends on people who do very different jobs, in very close quarters.

01

Keep the ship moving

Navigation, engineering, and deck operations make the science possible. The ship is both a workplace and a home.

02

Bring the ocean aboard

Samples and instrument records turn ocean conditions into evidence that scientists can study.

03

Work beyond the rail

Survey equipment connects a moving ship to the water and seafloor beneath it.

Meridian is fictional. The work has real counterparts: the University of Delaware’s R/V Hugh R. Sharp supported NOAA’s Atlantic sea scallop dredge survey from 2008 to 2023.

04 / The Gulf of Maine

The sea has
a long memory.

Beneath the water is a landscape shaped by ice.

The Gulf of Maine’s glaciated seafloor holds exposed bedrock, gravel, and areas of finer sediment. What looks like an unbroken surface from the ship conceals a varied landscape below.

That physical ground matters to the living world above it. Understanding habitat begins with understanding what’s underfoot—even when it’s out of sight.

Explore it ashore

The coast is closer than you think.

You don’t need a research vessel to start exploring. Discover the rocky shore and tide pools at Odiorne Point in New Hampshire, or explore the coastal ledges at Two Lights State Park in Maine.

Odiorne Point · Rye, NH

Start with Seacoast Science Center’s guide to the tide pools just outside its doors.
