by Rising Tide | Sep 9, 2014 | Conservation, Fish, MACNA, ScienceFigure. Samantha Groene in the Rising Tide booth at MACNA 2014. My name is Samantha Groene, and I am a biological technician at UF-TAL. I’ve been with the lab for almost two years, but this is my first official introduction on the Rising Tide Conservation blog. This past week, some of you might have seen me in Denver. The annual Marine Aquarium Conference of North America (MACNA) took place in Denver, Colorado this year and I had the privilege of representing Rising Tide at the conference! This year's MACNA was quite the experience!
