Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for...
The Gulf Stream is a major conduit of warm surface water from the tropics to the subpolar North Atlantic. Here we observe and simulate a submesoscale (<20 km) mechanism by which the Gulf Stream exchanges water with subpolar water to the north. Along isopycnals, the front has a sharp compensated...
Current and hydrographic observations from the Coastal Mixing and Optics
experiment moored array, deployed from August 1996 through June 1997, are used to
describe the velocity variability and evaluate the dynamics of circulation over the New
England shelf on timescales ranging from a few days to several months. Subtidal (days...

This report summarizes the Seasoar and CTD observations from Wecoma
cruises W9306A (5 June to 12 July, 1993) and W9308B (14 August to 22 September
1993) conducted as part of the Eastern Boundary Currents Accelerated Research
Initiative, under funding by the Office of Naval Research. The cruises were
designed to...
In 2005, the onset of spring conditions in the physics
of the coastal ocean (lowered sea level, spin-up of
vertically-sheared equatorward coastal jet) came about 50
days later than average off Newport Oregon, on May 24.
There was a further delay of 50 days before the subsurface
upwelled water penetrated...
Observations from the Coastal Mixing and Optics experiment moored array, deployed
from August 1996 through June 1997, are used to describe barotropic and baroclinic
tidal variability over the New England shelf. The dominant M₂ tidal elevations decrease
toward the northeast to a minimum over the Nantucket shoals (about 34 cm),...

Observations from the Coastal Mixing and Optics (CMO) moored array (deployed from August 1996 through June 1997) and supplemental moored observations are used to describe near-inertial current variability over the New England shelf. Near-inertial band current variance comprises 10–20% of the total observed current variance, and has episodic peak speeds...
Sea surface temperature variations along the entire U.S. East Coast from 1875 to 2007 are characterized using a collection of historical observations from lighthouses and lightships combined with recent buoy and shore-based measurements. Long-term coastal temperature trends are warming in the Gulf of Maine [1.0° ± 0.3°C (100 yr)⁻¹] and...
