The MESO-SCOPE (Microbial Ecology of the Surface Ocean -
Simons Collaboration on Ocean Processes and Ecology) expedition collected oceanographic
observations in the region north of the Hawaiian Islands with the aim of identifying
the impact of mesoscale eddies on the ecosystem of the North Pacific Subtropical Gyre.
The expedition targeted a mesoscale dipole north of the island of Oahu (eddies C1 and A1
in the figure) to characterize: 1) the horizontal variability in biogeochemical and
ecological properties across the two eddies; and 2) Lagrangian temporal dynamics at the
two eddy centers, with a particular focus on diel processes.
