Woods Hole Oceanographic Institution

Our lab is focused on observing ocean circulation and understanding its underlying physics. Ultimately, we seek to quantify the role of ocean circulation in the climate system. Specific areas of interest include:

  • The Atlantic Meridional Overturning Circulation (AMOC), an intricate system of currents that stabilizes the earth’s climate by redistributing heat, salt, oxygen, and carbon on a global scale.

  • High-latitude ocean dynamics and the linkages between the Arctic and Atlantic oceans.

Research Projects

MEZCAL

Methods for Extending the horiZontal Coverage of the Amoc Latitudinally and retrospectively

Western Irminger Sea Ventilation

Investigating the processes that govern boundary current ventilation using year-round moored observations of oxygen in the western Irminger Sea.

SNAP-DRAGON

Subpolar North Atlantic Processes - Dynamics and pRedictability of vAriability in Gyre and OverturNing. A UK-US collaboration to improve our understanding of a key ocean region.

Beaufort Gyre Observing System

The Beaufort Gyre is one of the Arctic Ocean’s main dynamical sea-ice and ocean circulation systems, its major freshwater reservoir, and a centerpiece for Arctic and global change.

AMOC connectivity

We are compiling a novel dataset at about 37N using satellite, float, and mooring observations to test the connectivity of the Atlantic Meridional Overturning Circulation (AMOC).

Oxygen cycling in the Irminger Sea

Probing the physical and biological controls on the Irminger Seas’s oxygen cycle using moored Oceans Observatories Initiative (OOI) and Bio-Argo data.
