And why should we care what causes a drought?

For this early part of the season the goal is to tease apart a record of historic precipitation and temperature for this region using isotopes from leaf waxes collected in the lake sediments.

Lamont-Doherty researchers will use the grant to enhance a sample identification system that makes scientific results more reproducible.

Superheroes are identified by their unique powers and skills, allowing them to see and act in ways that inspire awe in the rest of us. Do scientists have superhero powers?

Researchers from the Lamont-Doherty Earth Observatory are exploring how volcanic inputs are influencing ocean health in Hawaii.
