Gray’s Reef National Marine Sanctuary Foundation invites you to discover the wonders of the Atlantic Ocean by listening to the acoustic soundscape recordings in the NOAA underwater sound monitoring study. This project is a collaboration between NOAA and the U.S. Navy to better understand underwater sound within the National Marine Sanctuary System.

Our Sanctuary Soundscapes project, featured on SoundCloud, invites you to immerse yourself in Gray’s Reef!

Citizen Scientists and students of all ages can take a deeper dive into the project and contribute metadata to help categorize sanctuary sounds.

Sanctuary Soundscapes FAQ:

The purpose of the Sanctuary Soundscapes project is to bring awareness to our National Marine Sanctuaries and better understand our ocean soundscapes and how we impact them. Citizen scientists are integral to this process because of the sheer magnitude of data that exists. Having citizen scientists performing initial analyses will only increase the efficiency of our processing. For example, a citizen may analyze a 4-hour recording and determine that there are only 2 hours of a specific sound. When experts perform a more in-depth analysis, they will know to focus on the areas identified by our citizen scientists.

One of the key species we are focusing on with this research is the North Atlantic Right Whale. This is the most endangered whale species, and we know that Gray’s Reef National Marine Sanctuary is located in the only known nursery grounds for these animals. If we can locate Right Whales within these data, we could determine when and how they utilize Gray’s Reef to better monitor and protect them.

We will offer training to each citizen scientist before they dive into the data. At Gray’s Reef, we are aware of at least 31 species of soniferous fishes and six species of mammals, 40 species of birds, two reptiles species, and five invertebrates species. Some of these sounds are very distinctive, but others may only be grouped into general categories, like grunts, snaps, or moans.

Absolutely. The website and SoundCloud page are both live. Anyone interested in participating can register for the upcoming web training.

All that is needed to participate is a computer, a pair of headphones, and the free analysis software we will be using, RavenLite. Once we receive their registration, we will reach out with details, including how to access and download the software and schedule virtual training sessions.

Part of the training will cover how to access files, and we will monitor who is working on which files so that we can prevent overlap. However, multiple people may work on the same files but focus on different frequency ranges.
