Global Coastal Ecosystem Responses to a Half-Century Increase in River Nitrogen Loads

March 16, 2022

Coastal oceans host diverse ecosystems and serve as important habitats for marine fish species. Over the past century, anthropogenic activities have resulted in substantial climatic and land use changes that stress coastal environments, often leading to eutrophication, harmful algal blooms, and deoxygenation. Rivers are a primary source of eutrophication, supplying an increasing amount of anthropogenic nitrogen to the coastal ocean over the past century. A recent study, led by former AOS Postdoc Xiao Liu (IMSG and NOAA NWS NCEP/EMC), investigates coastal ecosystem responses to increasing river nitrogen loads for the period between 1959 and 2010. Liu conducted the work while at Princeton with collaborators Charles Stock (GFDL), John Dunne (GFDL), AOS Associate Research Scholar Minjin Lee, Elena Shevliakova (GFDL/HMEI), Sergy Malyshev (GFDL/HMEI), and P.C.D. (Chris) Milly (GFDL).
