Tuesday Noon Balloon with Ajit Subramaniam


Great Rivers and Changing Oceans

Ajit Subramaniam

Tuesday February 8th
Room 417 Schermerhorn Hall


Summary: The ten largest rivers in the world contribute 38% of all riverine input into the oceans. Their plumes extend 100’s to 1000’s of kilometers offshore and are important conduits for terrigenous nutrients to the oceans. Direct anthropogenic activity through land and water use change as well as indirect climate change effects are altering the chemistry of these rivers and consequently the marine ecosystem influenced by the plumes. We have to understand the biogeochemical cycles affected by these river plumes in order to predict changes to the marine ecosystem in the future. The implications of changes to the global carbon and nitrogen cycles associated with changes to these river plumes will be presented.

Ajit SubramaniamDr. Ajit Subramaniam is Lamont Associate Research Professor and a biological oceanographer at Lamont-Doherty Earth Observatory of Columbia University. His main fields of research include oceanography, remote sensing, bio-optics, and coastal water quality.  He is interested in the use of remote sensing, ocean optics, phytoplankton physiology, biological and physical oceanography and geographical information systems to better understand how the marine ecosystem works and can be managed.  He is also actively involved in research on the use of bio-optics and remote sensing as tools for monitoring coastal water quality.

Ajit received his B.Sc. in Physics at The American College, and his M.S. in Marine Envrionmental Sciences and Ph.D. in Coastal Oceanography from SUNY Stony Brook.

Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall.  Attendees are welcome to bring their lunch.

All are welcome to attend!
