White rot, caused by Sclerotium cepivorum, is a serious disease that causes significant yield losses in Allium production. The pathogen persists in soil as sclerotia, which germinate in response to sulfur compounds in Allium root exudates. This study was aimed at investigating the potential of early-terminated Allium bait crops to...
Over recent decades, the Bering Sea has experienced oceanic and atmospheric
climate extremes, including record warm ocean temperature anomalies and marine heatwaves (MHWs), and increasingly variable air-sea heat fluxes. In this work, we assess the relative roles of surface forcing and ocean dynamical processes on mixed layer temperature (MLT) tendency...
Global warming is expected to cause significant changes in the pattern of precipitation minus evaporation (𝑃 − 𝐸), which represents the net flux of water from the atmosphere to the surface or, equivalently, the convergence of moisture transport within the atmosphere. In most global climate model simulations, the pattern of...
For 30 years, the pathogen Haplosporidium nelsoni (MSX) has been causing serious mortalities of eastern oysters Crassostrea virginica in the Delaware and Chesapeake bays. Its life cycle is largely unknown, and methods for control are wanting. Breeding of resistant eastern oyster strains, at this time, offers the best hope for...
Perkinsus marinus is a warm-season protozoan pathogen (Phylum Apicomplexa) that parasitizes eastern oysters Crassostrea virginica from Chesapeake Bay to the Gulf of Mexico. In years of normal rainfall in Chesapeake Bay, P. marinus is limited by low salinities in the estuaries and is dormant during winter and spring. A few...
This case study explores how to add value to regional ocean condition forecast information by bringing awareness to the processes that govern decision-making and outcomes within the system. A modified mental models research approach is applied to examine differences and similarities in perceptions of risk and comfort with uncertainty between...
The impact of a tsunami can vary greatly across short distances due to differences in topography, building structures, concentration of economic activities in the inundation zone, and economic linkages beyond the inundation zone. This study takes these factors into account in an analysis of a potential tsunami on the West...
We present double-differential measurements of antineutrino charged-current quasielastic scattering in the MINERvA detector. This study improves on a previous single-differential measurement by using updated reconstruction algorithms and interaction models and provides a complete description of observed muon kinematics in the form of a double-differential cross section with respect to muon...
This study investigates wind-driven circulation in the vicinity of the Heceta Bank complex along the Oregon shelf. Numerical experiments forced with steady winds (0.1 Pa) are conducted; upwelling and downwelling cases are compared. The asymmetric bank bathymetry is the only configurational difference from the symmetric bank runs analyzed in Part...
