The accuracy of state-of-the-art global barotropic tide models is assessed using bottom
pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and
independent tracked satellite orbit perturbations. Tide models under review include empirical, purely
hydrodynamic (“forward”), and assimilative dynamical, i.e., constrained by observations. Ten dominant...
Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...
This exploratory study was focused on the design, meaning and use of the Turkish salon (the sitting room for guests). The findings provided an understanding of the different aspects of people's experiences of their salons. Socially and personally constructed meanings were examined to gain a deeper understanding of the respondents'...
Clinicians make a variety of judgments about their clients, from judging personality traits to making diagnoses, and a variety of methods are available to do so, ranging from observations to structured interviews. A large body of work demonstrates that from a brief glimpse of another’s nonverbal behavior, a variety of...
Anaerobic digestion is a microbially mediated process by which organic matter is decomposed in the absence of oxygen. The end products of anaerobic digestion include treated sludge and biogas, a mixture of methane and carbon dioxide, which can be recovered and used for energy generation. The majority of wastewater treatment...
We assimilate localized mass anomalies inferred from
GRACE ranging measurements into a hydrodynamic model
to improve tidal solutions around Antarctica for the M2, S2,
and O1 constituents. The variational approach used accounts
for the spatial averaging of tidal elevations implicit in the
mass anomaly parametrization used for the GRACE tidal...
A hydrodynamic model incorporating a self‐consistent treatment of ocean self‐attraction and loading (SAL), and a physically based parameterization of internal tide (IT) drag, is used to assess how accurately barotropic tides can be modeled without benefit of data, and to explore tidal energetics in the last glacial maximum (LGM). M2...
The small S₁ ocean tide is caused primarily by diurnal atmospheric pressure loading. Its excitation is therefore unlike any other diurnal tide; in particular, pressure loading is maximum near the equator where the diurnal gravitational potential is zero. The global character of the S₁ tide is here determined by numerical...
Present methods used to retrieve altimeter data do not provide reliable estimates of
sea surface height (SSH) in the nearshore region, resulting in a measurement gap of
25–50 km next to the coast. In the present work, gridded SSH fields produced by
Archiving, Validation, and Interpretation of Satellite Oceanographic data...
Early embryo development is dependent on maternally derived RNA and protein synthesized during oogenesis. In the bovine embryo this dependence lasts until the 8-16 cell stage, at which time embryonic transcripts become essential for continued development. One proposed mechanism for this transition from maternal to zygotic control of development (maternal...
