The ocean is one of Earth鈥檚 largest and most effective carbon sinks. With every wave, carbon is collected from the atmosphere, stored in marine life, plants, sediments and more 鈥� known as blue carbon.聽
, a scientist at 新加坡六合彩开奖直播, is researching eelgrass and its importance to Atlantic Canada鈥檚 blue-carbon stores.聽
The project, 鈥淓stablishing the value of blue carbon to Nova Scotia: a case study,鈥� involves researching why eelgrass is disappearing and how it can be restored. This project is supported financially through the , which has enabled the initiative to blossom and thrive.聽
Exploring eelgrass in Atlantic Canada
Eelgrass, known by its scientific name Zostera marina, is a unique species of seagrass. It is the only marine plant with both shoots and rhizomes that live completely under the water. In Atlantic Canada, eelgrass species are found in underwater meadows along coastlines where they thrive in the shallow waters and soft sediments.
Dr. Boerder and research partners at Dal began exploring eelgrass in 2020.
鈥淲e paddled and snorkeled around [Owls Head] and found these lush, dense, healthy eelgrass meadows,鈥� says Dr. Boerder. 鈥淚've snorkeled in a couple [meadows] around Nova Scotia, but I had never seen something like that.鈥�

In the ocean, seagrasses are responsible for storing nearly 10 per cent of the world鈥檚 carbon each year, even though they cover a mere 0.2 per cent of the ocean floor. The carbon travels through their roots and into the sediment, where carbon can accumulate vertically as the sea level rises 鈥� meaning seagrasses can continue to sequester carbon indefinitely if undisturbed.聽
A restoration initiative
Despite the ample eelgrass presence along Nova Scotia鈥檚 coastline, the amount of carbon it sequesters has yet to be quantified.聽Community Eelgrass Restoration Initiative (CERI) was established to help fill this knowledge gap and explore why eelgrass is disappearing around the province.
The project initially began with groups of volunteers and was funded through small grants from organizations like the and the .
The OFI seed fund provided the foundation for the establishment of CERI and its research abilities by funding new research equipment, labs and training. CERI now has over 12 research sites across Nova Scotia, New Brunswick, and Prince Edward Island.
鈥淏y the third year, the OFI seed fund kicked in and that is what really enabled us,鈥� says Dr. Boerder. 鈥淚t was the first meaningful amount of funding that allowed us to plan in a proper scientific way.鈥�

CERI has four main initiatives throughout their project: mapping eelgrass locations; easuring eelgrass carbon sequestration; restoring eelgrass meadows; outreach and education.
Currently, CERI is focusing on restoring meadows around Nova Scotia. There is a lack of knowledge regarding the province鈥檚 eelgrass meadows. Researchers do not know how many meadows the province has already lost.聽
However, this novel eelgrass and sediment research is adding vital information to the growing scientific database, putting Nova Scotia on the map for its world-class ocean research.
A community effort
The project relies heavily on citizen scientists in communities to help gather knowledge and stories of past eelgrass meadows.
The team is heavily centered on a two-eyed seeing approach, ensuring that the 新加坡六合彩开奖直播 researchers are an equal partner with the Confederacy of Mainland Mi鈥檏maq.

鈥淗aving such a diverse and engaged team really helps because the ideas and creativity with that is really helpful and inspiring to see,鈥� says Dr. Boerder.
To accomplish its restoration goals, CERI is working with communities across Nova Scotia to replant damaged eelgrass meadows.聽
鈥淲e see that people really want to be part of a solution,鈥� says Dr. Boerder. 鈥淚n Nova Scotia, we use it like a gateway into marine conservation and restoration, which nearly every member of the public that I speak to has no idea that it's possible.鈥�
