State University of New York-Brockport graduate student, Tom Bianchi, interprets alewife otolith ages (foreground) while student contractor Scott Minihkiem (background) mounts otoliths in epoxy. Bianchi is evaluating how alewife age influences reproductive success and was trained in otolith techniques at the GLSC’s Lake Ontario Biological Station.

Carson Pritchard (left), a former GLSC contractor and 4-H camp counselor, shows off a Great Lakes Chinook salmon with a 4-H camper. Alewife are the primary forage of Chinook salmon. Consequently, understanding alewife age dynamics helps fishery managers balance predator numbers with the available prey.

A section of the Porcelain Basin Loop boardwalk in the Norris Geyser Basin was removed because the ground below sections of the boardwalk became too hot and made charcoal of the wood footings that support the structure. Luckily enough in this case, the boardwalk was shifted about 3 feet to avoid the new hot ground.
