A couple of weeks ago, I had the opportunity to visit Øresund Aquarium in Helsingør for a field study focused on the importance of seagrass. While I had heard about its ecological role before, experiencing it firsthand at Kronborg Bay truly brought its significance to life.

After a brief introduction from the aquarium staff, we suited up in waterproof gear and headed to the bay for some hands-on sampling. The Kronborg Bay area, part of the Øresund strait, is home to a seagrass restoration project aiming to revive these vital underwater ecosystems. Seagrass meadows support an incredible range of marine life, and our task was to experience the work that goes into studying and restoring them.

Wading into the bay, we pulled a net through the water, collecting samples to get a better understanding of the biodiversity within the seagrass meadows. It was fascinating to see how different species rely on this environment for shelter and food. Along the way, we spotted a number of jellyfish washed up on the shore, and the staff introduced us to common species found in the area, such as starfish, crabs, and rockfish. It was the first time seeing and even touch some of these species in my life, and it was really fascinating to hear about their special traits and living habits.
This experience offered more than just a glimpse into marine life; it also highlighted the essential role seagrass plays in coastal ecosystems. Seagrass meadows are not only nurseries for many species but also serve to stabilize coastlines by reducing erosion. On a larger scale, they act as carbon sinks, helping to mitigate the effects of climate change by absorbing and storing carbon dioxide from the atmosphere. The field study was both educational and rewarding, providing valuable insight into the efforts required to protect these fragile ecosystems. The restoration of seagrass meadows, like those in Kronborg Bay, is crucial not only for marine biodiversity but also for human communities, as they offer numerous environmental benefits. It was an eye-opening experience that left me with a deeper appreciation for marine conservation efforts and the important work being done to restore these valuable habitats.
