OCEAN NITROGEN
BIOGEOCHEMISTRY
The Granger Lab studies nitrogen cycling in the marine environment to understand how natural and pollutant sources of nitrogen influence near shore water quality and open ocean fertility. We strive to uncover how the combined activities of diverse microbes in the ocean contribute to the production, cycling, and loss of reactive N from marine ecosystems.
Current Research Includes:
Conducting regional surveys of nitrate isotope distributions in diverse ocean domains – including the Arctic Ocean, the North and South Atlantic, and the western tropical Pacific – to investigate N cycling at regional and basin scales.
Using measurements of nitrogen isotope ratios in near-shore environments to identify contributions of pollutant sources
Investigations into the physiological bases of microbial N transformations and associated N isotopic imprints in laboratory cultures to provide benchmarks to interpret observations in the environment.
Conducting regional surveys of nitrate isotope distributions in diverse ocean domains – including the Arctic Ocean, the North and South Atlantic, and the western tropical Pacific – to investigate N cycling at regional and basin scales.
Our work thus reflects the different scales of nitrogen biogeochemistry,
from biochemical to global.
