Submesoscale streamers exchange water on the north wall of the Gulf Stream

Creator:: Klymak, Jody M., Shearman, R. Kipp, Gula, Jonathan, Lee, Craig M., D'Asaro, Eric A., Thomas, Leif N., Harcourt, Ramsey R., Shcherbina, Andrey Y., Sundermeyer, Miles A., Molemaker, Jeroen, and McWilliams, James C.
Abstract:: 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...

Anomalous Near-Surface Low-Salinity Pulses off the Central Oregon Coast

Creator:: Mazzini, Piero L. F., Risien, Craig M., Barth, John A., Pierce, Stephen D., Erofeev, Anatoli, Dever, Edward P., Kosro, P. Michael, Levine, Murray D., Shearman, R. Kipp, and Vardaro, Michael F.
Abstract:: From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m³/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010–2011 La Niña....

Shafer, Tandon, Amit, Taylor, John R., Terray, Eugene A., Thomas, Leif N., and Ledwell, James R.
Abstract:: 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...

Buoyancy-Driven Coastal Currents off Oregon during Fall and Winter

Creator:: Mazzini, Piero L. F., Barth, John A., Shearman, R. Kipp, and Erofeev, A.
Abstract:: During fall/winter off the Oregon coast, oceanographic surveys are relatively scarce because of rough weather conditions. This challenge has been overcome by the use of autonomous underwater gliders deployed along the Newport hydrographic line (NH-Line) nearly continuously since 2006. The discharge from the coastal rivers between northern California and the...

Deploying Dissolved Oxygen Sensors On Crab Pots for Ocean Observations Researchers Partner With Fishermen to Use Auto- Reporting Bottom-Positioned Sensors for Ocean Research

Creator:: Shearman, R. Kipp and Childress, Jeremy L.
Abstract:: Over the past decade, regional ocean observing systems have been established along nearly the entirety of the U.S. coastlines, forming a major component of the national Integrated Ocean Observing System (100S). Observations from these systems provide information to support decision making by governmental agencies and commercial enterprises, such as shipping...

Declining Oxygen in the Northeast Pacific

Creator:: Pierce, Stephen D., Barth, John A., Shearman, R. Kipp, and Erofeev, Anatoli Y.
Abstract:: Climate models predict a decrease in oceanic dissolved oxygen and a thickening of the oxygen minimum zone, associated with global warming. Comprehensive observational analyses of oxygen decline are challenging, given generally sparse historical data. The Newport hydrographic (NH) line off central Oregon is one of the few locations in the...

Evaporative dense water formation and cross‐shelf exchange over the northwest Australian inner shelf

Creator:: Shearman, R. Kipp and Brink, Kenneth H.
Abstract:: High‐resolution surveys of oceanographic and atmospheric conditions made during the winter over the inner shelf off northwest Australia are used to examine the coastal ocean response to large outgoing heat and freshwater fluxes. Relatively cool, low‐humidity air blows off the Australian continent out over the tropical continental shelf, resulting in...

Long-Term Sea Surface Temperature Variability along the U.S. East Coast

Creator:: Shearman, R. Kipp and Lentz, Steven J.
Abstract:: 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...

Alongshore currents and mesoscale variability near the shelf edge off northwestern Australia

Creator:: Brink, K. H., Bahr, Frank, and Shearman, R. Kipp
Abstract:: Shelf break conditions and alongshore flow off northwestern Australia are studied during the strongly evaporative conditions of austral winter 2003. Present results, along with those of previous authors, confirm that a poleward, fresh Leeuwin current core is normally found near the shelf break. Salinity increases alongshore toward the southwest. Although...

Bottom boundary layer flow and salt injection from the continental shelf to slope

Creator:: Brink, K.H. and Shearman, R. Kipp
Abstract:: Austral winter oceanographic measurements from the northwest Australian continental shelf reveal salty water forming evaporatively inshore, moving across the wide shelf near the bottom and into the adjacent open ocean when the shelf edge alongshore flow is equatorward. The salt tongue is absent during more normal conditions, when the poleward...

Physical versus biological spring transition: 2005

Creator:: Kosro, P. Michael, 1951-, Peterson, William T., Hickey, Barbara M., Shearman, R. Kipp, and Pierce, Stephen D.
Abstract:: 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 of near-inertial current variability on the New England shelf

Creator:: Shearman, R. Kipp
Abstract:: 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...

Creator:: Barth, John A., Cowles, Timothy J., Kosro, P. Michael, 1951-, Shearman, R. Kipp, Huyer, Adriana, 1945-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: High concentrations of chlorophyll are found in the California Current System over 300 km offshore, far from the productive coastal upwelling region, and between 150 and 250 m, well below the depth to which photosynthetically active solar radiation penetrates. This exceptionally deep chlorophyll feature is formed near the coast and...
