Multimedia journalists Julia Reihs and Zolboo LiLi Bayarmagnai spent much of the 2014 expedition following Notre Dame University researcher Carmella Vizza as she studied pond ecosystems on the Copper River Delta. She gathers information annually about how the ponds transform in the face of climate changes on the Delta. In six lessons, the stories of pond ecosystems show the life of a researcher.
Her first summer in Cordova, Alaska, Carmella Vizza fell in love with the Copper River Delta as a place with endless possibilities for her research about pond ecosystems. The ponds are the foundations of the food chain on the Delta, providing a home for small organisms, insects and birds that affect everything from the salmon cycle to predatory bears. A graduate student researcher from Notre Dame University, Vizza works each summer to gather information about how ponds transform in the face of climate change, and the repercussions this may have on the entire ecosystem.
