Coastal flood hazard zones and the design of coastal defenses are often devised using the maximum
recorded water level or a ‘‘design’’ event such as the 100 year return level, usually projected from
observed extremes. Despite technological advances driving more consistent instrumental records of waves
and water levels, the observational...
Balanced nutrition is important for efficient livestock production.
Daily nutrient requirements vary depending on the phase of production. Knowing the nutrient composition of feeds and matching feeds to animal requirements at a given stage of production will ensure that nutritional needs are met. Forage analysis is a management tool that...
Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding...
A form of the linear, inviscid shallow water wave equation which includes alongshore uniform, but cross-shore variable, longshore currents and bathymetry is presented. This formulation provides a continuum between gravity waves (either leaky or edge waves) on a longshore current, and the recently discovered shear waves. In this paper we...
Probabilistic flood hazard assessment is a promising methodology for estuarine risk assessment but currently remains limited by prohibitively long simulation times. This study addresses this problem through the development of an emulator, or surrogate model, which replaces the simulator (in this case the coupled ADCIRC+SWAN model) with a statistical representation...
Planetary or Rossby waves are the predominant way in which the ocean adjusts on long (year to decade) timescales. The motion of long planetary waves is westward, at speeds ≥1 cm s⁻¹ . Until recently, very few experimental investigations of such waves were possible because of scarce data. The advent...
The authors have used a spectral, primitive equation mechanistic model of the stratosphere and mesosphere
to simulate observed stratospheric flow through the winters of 1991–92 and 1994–95 by forcing the model at
100 hPa with observed geopotential height. The authors assess the model’s performance quantitatively by
comparing the simulations with...
Mastitis is the single most expensive disease to the dairy industry, contributing to large financial losses due to decreased quantity and quality of milk. It's essential to develop and implement a mastitis
control program to keep mammary glands healthy and reduce infection in the herd. Removing the hair from a...
During the discovery and description of seven New Zealand methane seep sites, an infaunal assemblage dominated by ampharetid polychaetes was found in association with high seabed methane emission. This ampharetid-bed assemblage had a mean density of 57,000 ± 7800 macrofaunal individuals m⁻² and a maximum wet biomass of 274 g...
Abstract: Significant declines in spring Northern Hemisphere (NH) snow cover extent (SCE) have been observed over the last five decades. As one step toward understanding the causes of this decline, an optimal fingerprinting technique is used to look for consistency in the temporal pattern of spring NH SCE between observations...
