| 説明 | While in the Upper Delaware, National Park Service (NPS) staff helped DRBC with the biomonitoring efforts. Pictured here is Erica Spiess from NPS helping DRBC's Megan Andreason filter river water for chlorophyll-a analyses. These filters are frozen and will be later sent to the Academy of Natural Sciences. |
