Geochemical markers for fish life history

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Megan Nims

This proposal involves two different projects using geochemical markers to investigate questions regarding fish life history. Fish have structures called “otoliths,” which are made out of calcium…

Using Oxygen Isotope Fractionation (delta-18O) in Otoliths to Characterize the Temperature History of Fall Chinook Salmon

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Timothy Linley

Project type

Exploratory Research

Fall Chinook salmon in the Snake River are listed as threatened under the Endangered Species Act. A potential factor limiting their recovery is the impact from hydropower generation on river…

Expanding EMSL's isotope analysis capability to additional environmentally relevant sample types

Lead Institution

Michigan State University

Principal Investigator

James Moran

We seek to modify instrument peripheral devices and develop needed methods to expand the suite of analytes that can be analyzed using the EMSL isotope ratio mass spectrometry (IRMS) capability…
