Delayed upwelling alters nearshore coastal ocean ecosystems in the northern California current

Creator:: Barth, John A., Menge, Bruce A., Lubchenco, Jane, Chan, Francis, Bane, John M., Kirincich, Anthony R., McManus, Margaret A., Nielsen, Karina J., Pierce, Stephen D., and Washburn, Libe
Abstract:: Wind-driven coastal ocean upwelling supplies nutrients to the euphotic zone near the coast. Nutrients fuel the growth of phytoplankton, the base of a very productive coastal marine ecosystem [Pauly D, Christensen V (1995) Nature 374:255–257]. Because nutrient supply and phytoplankton biomass in shelf waters are highly sensitive to variation in...

Community Responses to Climate-Related Variability and Disease: The Critical Importance of Long-Term Research

Creator:: Menge, Bruce A., Caselle, Jennifer E., Barth, John A., Blanchette, Carol A., Carr, Mark H., Chan, Francis, Gravem, Sarah, Gouhier, Tarik C., Lubchenco, Jane, McManus, Margaret A., Milligan, Kristen, Novak, Mark, Raimondi, Peter T., Washburn, Libe, and White, J. Wilson
Abstract:: A major goal of the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) has been to understand the impacts of climate change and variability on the coastal ecosystems of the inner shelf of the California Current Large Marine System in particular, and other marine and even nonmarine systems more generally....

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...

Occurrence of demersal fishes in relation to near-bottom oxygen levels within the California Current large marine ecosystem

Creator:: Keller, Aimee A., Ciannelli, Lorenzo, Wakefield, W. Waldo, Simon, Victor, Barth, John A., and Pierce, Stephen D.
Abstract:: Various ocean-climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen (DO) as a result of greater stratification, reduced ventilation below the thermocline, and decreased solubility at higher temperatures. Since spreading of low oxygen waters is underway and predicted to increase, understanding impacts...

Connectivity and larval dispersal along the Oregon coast estimated by numerical simulations

Creator:: Kim, Sangil and Barth, John A.
Abstract:: Connectivity and larval dispersal is explored off the Oregon coast during the summer upwelling season of 2001 using numerical ocean circulation simulations. The study region, with strong wind-driven currents and variable topography, is modeled using the Regional Ocean Modeling System (ROMS) forced by the Coupled Ocean Atmosphere Mesoscale Prediction System....

The Dynamics and Impact of Ocean Acidification and Hypoxia: Insights from Sustained Investigations in the Northern California Current Large Marine Ecosystem

Creator:: Chan, Francis, Barth, John A., Kroeker, Kristy J., Lubchenco, Jane, and Menge, Bruce A.
Abstract:: Coastal upwelling ecosystems around the world are defined by wind-generated currents that bring deep, nutrient-rich waters to the surface ocean where they fuel exceptionally productive food webs. These ecosystems are also now understood to share a common vulnerability to ocean acidification and hypoxia (OAH). In the California Current Large Marine...

Introduction to special section : Coastal Advances in Shelf Transport

Creator:: Barth, John A. and Wheeler, Patricia A.
Abstract:: The Coastal Ocean Advances in Shelf Transport (COAST) program conducted an interdisciplinary study of coastal upwelling off central Oregon during summer 2001. Two intensive field efforts during May–June and August 2001 were coordinated with ocean circulation, ecosystem, and atmospheric modeling of the region. A primary goal was to contrast the...

Abstract:: Twenty years ago, the creation of a new scientific program, the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), funded by the Packard Foundation, provided the opportunity to integrate—from the outset—research, monitoring, and outreach to the public, policymakers, and managers. PISCO’s outreach efforts were initially focused primarily on sharing scientific...

Time-dependent, wind-driven flow over a shadow midshelf submarine bank

Creator:: Barth, John A., Pierce, S. D., and Castelao, R. M.
Abstract:: During summer 2001, high-resolution hydrographic, velocity, and bio-optical surveys were conducted over Heceta Bank off central Oregon. North of the bank, upwelling over simple bottom topography exhibited a classic response with a midshelf, baroclinic coastal jet and upwelled isopycnals. The coastal upwelling jet follows the bank topography as it widens...

Temporal variability of near-bottom dissolved oxygen during upwelling off central Oregon

Creator:: Adams, Katherine A., Barth, John A., and Chan, Francis
Abstract:: In the productive central-Oregon coastal upwelling environment, wind-driven upwelling, tides, and topographic effects vary across the shelf, setting the stage for varied biogeochemical responses to physical drivers. Current, temperature, salinity, and dissolved oxygen (DO) measurements from three moorings deployed during the upwelling seasons of 2009–2011 off the central-Oregon coast are...
