A Cape Cod-based nonprofit organization that chases — and researches — great white sharks is giving people a chance to attach their names to high-tech buoys used to study the fearsome ocean predators.

The Atlantic White Shark Conservancy this week invited donors to sponsor the acoustic buoys. The bright yellow devices are used to detect great white sharks that the group has tagged with acoustic transmitters during its expeditions off the coast.

When a shark outfitted with a tag swims within a 200-yard radius of a buoy, the date and time is recorded. Researchers make boat trips to the buoys to download the information collected.

The researchers said the devices are “a critical piece’’ of research into the sharks’ movements, showing how sharks migrate to the Cape Cod area to feast on seals when the weather gets warmer.

Such buoys have floated off Cape Cod since 2010, monitoring shark movements in Chatham, Orleans, and Truro. Last summer, more buoys were placed off the coast of Duxbury and Plymouth.

For a $500 annual fee, donors will have a buoy named after them. Every time a great white is pinged near that donor’s buoy, the conservancy will notify the public on social media, giving the sponsor a shout-out. The person or business will also have their name listed on the “Sponsor’’ page of the organization’s website.

The donations will be used to maintain and expand the project, the conservancy said.

The conservancy conducts its research with biologists from the state’s Division of Marine Fisheries. Researchers typically make twice-weekly boat excursions during the great white shark season.

Last August, during a 4½-hour trip, researchers identified 16 sharks in different spots off the Cape Cod shoreline, setting a record for the season. Typically, they see five to 10 sharks per trip.
