“Living Shorelines” Can Fortify Our Coastlines … A Solution at Work in New Jersey’s Raritan Bay

After Hurricane Sandy, it was clear that coastal resiliency had become an immediate priority. Thus, Baykeeper began an innovative project to determine if a “Living Shoreline” of oysters could stabilize eroding shorelines of the urban New York-New Jersey Harbor Estuary. Perhaps they would simultaneously protect the surrounding environment, improve water quality, and create healthy aquatic habitats.

Oysters are powerful. They can filter and clean water, a much-needed service today. They can provide reef habitat for other sea creatures and improve resiliency to storm surge and erosion. Oysters once thrived in the NY-NJ Harbor Estuary — so much so that Ellis Island was previously called Little Oyster Island.  However, over-harvesting, pollution and the sedimentation of reefs resulted in a sharp population decline. Today there is no longer a sustainable oyster population in the NY-NJ Harbor area; but NY/NJ Baykeeper is working to restore them. As a bi-state restoration leader, NY/NJ Baykeeper has had restoration projects in both NJ and NY waters.

In mid-August, 2016, NY/NJ Baykeeper and its partners installed a first-of-its-kind urban “Living Shoreline” in northern New Jersey waters.  Located in the Raritan Bay at the Naval Weapons Station Earle in Monmouth County, a new 0.91 acre Living Shoreline consists of an artificial reef, using live oysters. Known as “oyster castles,” these new concrete structures are meant to provide the needed hard surface on which oysters can attach and grow. These 137 castles with about 10,000 oyster larvae can thus begin to fortify and protect the Raritan Bayshore.

In 2010 the NJ Department of Environmental Protection banned all shellfish research, restoration and education activities in waters (1) deemed too contaminated or (2) “Restricted” or “Prohibited” for shellfish harvest.  Thus earlier oyster reef projects in nearby Navesink River and Keyport Harbor had to be moved. At that point, the U.S. Navy and NY/NJ Baykeeper became “Living Shoreline” partners. The U.S. Navy at Naval Weapons Station Earle, with its non-accessible stretch of shoreline, provides protected property, guidance and valuable support for Baykeeper’s oyster restoration activities.

Additional restoration activities at Naval Weapons Station Earle include setting oysters at NY/NJ Baykeeper’s aquaculture facility near the mouth of Ware Creek, and monitoring the oysters and structures in the ¼-acre experimental restoration plot to assess survival and growth.

NY/NJ Baykeeper has monitored this Living Shoreline twice since its August installation, finding that the oysters grew 22mm in just 2 months!  Other organisms like sponges and algae are attached to the castles as well, further contributing to the Living Shoreline habitat.  All the castles have stayed in place, even during the rough seas when Hurricane Hermine was off shore. This is a good sign of how the castles will hold up in the dynamic Raritan Bay.

This winter, oyster growth will become slower as the water becomes cooler. Since all the oysters are far enough under the water’s surface, they will be protected should the Bay freeze over. Come spring, this Living Shoreline will be expanded, adding more castles and oysters to the system.  Meanwhile, NY/NJ Baykeeper continues its study of biodiversity  and its collection of water quality data.

LNG Threat to Hudson and Raritan River Estuaries

NY/NJ Baykeeper is a strong voice fighting an LNG terminal (see definition below) that would threaten the biodiversity and water quality of the Hudson and Raritan River Estuary, one of the largest ports in the world. LNG usage, which furthers greenhouse gas emissions, is also a concern.

WHAT is Liquefied Natural Gas (LNG)?

Liquefied Natural Gas is natural gas that has been super-chilled to minus 260 degrees, turning it into a liquid that is 1/600th the original volume of gas. It is clear, colorless, odorless, and extremely volatile. This gas is compacted so large volumes can be shipped overseas. LNG should not be confused with gasoline or compressed natural gas.

LNG is Expensive. The intensive energy use required to liquefy natural gas and shipping costs makes LNG up to three times more expensive than domestic natural gas.

LNG is Dirty. It results in up to 40% more greenhouse gas emissions than domestic natural gas due to a life cycle that requires super-cooling, transporting overseas in giant tankers, and heating back to gaseous form.

WHAT is Port Ambrose?
As proposed by Liberty Natural Gas (confusingly also called “LNG”),  “Port Ambrose” would be an offshore port for importing or exporting LNG to or from the coasts of New York and New Jersey. This port would allow two LNG vessels (which are as long as the World Trade Center Tower is tall) to directly connect to the region’s natural gas system, with a capacity that could be expanded.

PROTECT THIS ESTUARY and OUR OCEAN by supporting “The New Jersey/New York Clean Ocean Zone Act,” which is bi-partisan, bi-state legislation to permanently protect the waters off the NY/NJ coast from polluting activities and facilities, such as LNG ports.
