Two modifications to an existing scheme of tidal
mixing are implemented in the coarse resolution ocean component
of a global climate model. First, the vertical distribution
of energy flux out of the barotropic tide is determined
using high resolution bathymetry. This shifts the levels of
mixing higher up in the...

The reason for the initial rise in atmospheric
CO₂ during the last deglaciation remains unknown. Most recent
hypotheses invoke Southern Hemisphere processes such
as shifts in midlatitude westerly winds. Coeval changes in
the Atlantic meridional overturning circulation (AMOC) are
poorly quantified, and their relation to the CO₂ increase is
not...

Patterns of β diversity are commonly used to infer underlying ecological processes. In this study, we examined the effect of spatial configuration of habitat capacity on different metrics of β diversity, i.e., β diversity measured as turnover and as variation. For β diversity as turnover, a monotonic species spatial turnover...
As fisheries management shifts to an ecosystem-based approach, understanding energy pathways and trophic relationships in the Northern California Current (NCC) will become increasingly important for predictive modeling and understanding ecosystem response to changing ocean conditions. In the NCC, pelagic forage fishes are a critical link between seasonal and interannual variation...
This chapter synthesizes more than two decades of interdisciplinary scholarship by the coauthors related to fishing families and coastal communities. Amid the contemporary narrative of increasing coastal storms, erosion, and other physical hazards associated with climate and related coastal hazards facing coastal communities, we find myriad ways that Oregon fishing...
