There's more to kelp than meets the eye.","html":"<iframe width=\"100%\" height=\"180\" frameborder=\"no\" scrolling=\"no\" seamless src=\"https://share.transistor.fm/e/ffcaae41\"></iframe>","width":"100%","height":180,"duration":3361,"description":"Various species of kelp inhabit Oregon’s subtidal waters, providing food, nutrients, and shelter for an array of marine organisms. One such species, bull kelp, can be seen by divers towering over 50 feet above the seafloor as it grows rapidly, reaching for sunlight. Those not willing to brave the cold Oregon waters may stumble upon one during a beach walk — its leathery, green body resembling an oversized, thick whip after being torn from its holdfast by a recent storm.\nOur guest this week is Anna Dworetzky, a new PhD student whose research focuses on bull kelp. Anna is particularly interested in the holdfast — the root-like structure that anchors bull kelp to the seafloor. Anna plans to dive at sites stretching from California to Alaska to examine four genetically distinct bull kelp subpopulations, investigating how holdfast structural complexity relates to attachment strength and the communities of organisms living within them.","thumbnail_url":"https://img.transistorcdn.com/wOP_alqC4DV-nm5lKs286rPzpkhgXtr6wyOSpt-kJmk/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9kNDNj/ZmNiMGRhMmM5OGZj/ZmMyZTU2MTNiMDlh/M2UzMS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
