Saturday September 21 2019, David Black from SBU taught visitors to the LIA about sediment cores and tiny fossils that can be used to figure out about past climates.
August 17, 2019 – Strange But True: Shellfish Love Sweets Too!
Emmanuelle Pales Espinosa, Stony Brook University. Everybody love sweets so do oysters, clams and mussels. Join us as we meet with a local scientist to learn how these organisms feed but also how they select their food from a complex plankton mix with no eyes, no hands, no nose and no taste buds. Meet us from noon to 3pm on August 17th.
Amazing day a the LI Aquarium with Nils and PhD Student Ian Dwyer.
Nils and Ian connected sensors to a fiddler crab and a blue mussel so visitors can observed animal heartbeats directly on a screen like doctors will do! Isn’t it fascinating?!
Norah helped the little ones coloring shellfish and took some funny pictures.
May 18, 2019 – A heart-to-heart with clams and crabs
Nils Volkenborn, Stony Brook University. Meet with local scientist from the School of Marine and Atmospheric Sciences at StonyBrook and watch the heartbeat of hard-shelled animals in real-time and learn why and how scientists use heartbeat rate measurements to study their life in the coastal ocean. Do not miss the great show.

April 20, 2019 – Ocean Acidification: Seagrasses; A Last Hope
Alysson Lowell, Stony Brook University. Ocean acidification is further exacerbated by coastal influences like nutrient loading and runoff. The result is an environment more vulnerable and more intense for coastal marine organisms. Both low oxygen and high acidity combine to generate organisms more physiologically stressed than their open ocean counterparts. Seagrasses may provide a refuge for marine organisms in this highly dynamic and changing world. Highly productive producing oxygen rich and comparatively more basic environments, seagrasses are more attuned to the changing oceans than many of their macrophytic counterparts.
