Harbor School Oyster Work

Why Oysters?

Oysters and our CTE Department• Oysters, and oyster projects are excellent

platforms for our Career Training classes• We hope to have all of our CTE classes

working together on this project• To date Aquaculture, Advanced Vessel

Operations and the Student Scientific Divers have collaborated in building and monitoring our reefs

• In the future we hope to include Marine Engineering’s remote operated vehicles and Marine Policy’s young writers

Diving Safely in New York Harbor• SCUBA instructors Joe Gessert and

Liv Dillon organized a Dive control Board made up of commercial divers

• This led to new protocols including full face masks, tethered dives, and safety divers ready at all times

• Currently Harbor School is in the process of becoming a scientific diver training facility

• This project would not have been possible without the dedication of our divers

• Students and teachers routinely arrived on Governors Island hours before school, often while it was still dark

• Despite air temperatures below 40° and water temperatures below 50° all 250,000 oysters are down
