This one’s for you if you want to know what seaweed is and what it does in the ecosystem, whether sinking it in the deep ocean is a legit climate change solution and what a kelp trumpet sounds like. 

Dr Catriona Hurd is a seaweed physiologist with nearly 30 years experience across the planet studying how seaweeds grow and how they cope with things like ocean acidification and climate change. Her recent research in forensic carbon accounting assesses the role that seaweeds can play in carbon sequestration. 

You can find Dr Catriona Hurd at the Institute of Marine and Antarctic Science (UTAS). Thanks also to Ben Gerstein for lending me the sounds of his kelp trumpet, check out his music and sound work here. You can find and contact me @seaweed.people.
