Benthic diel oxygen variability and stress as potential drivers for animal diversification in the Neoproterozoic-Palaeozoic

open access: yesNature Communications
The delay between the origin of animals in the Neoproterozoic and their Cambrian diversification remains perplexing. Animal diversification mirrors an expansion in marine shelf area under a greenhouse climate, though the extent to which these ...

Lunar tidal acceleration obtained from satellite-derived ocean tide parameters [PDF]

open access: yes
One hundred sets of mean elements of GEOS-3 computed at 2-day intervals yielded observation equations for the M sub 2 ocean tide from the long periodic variations of the inclination and node of the orbit.

Effects of the oceans on polar motion: Continued investigations [PDF]

open access: yes
Data on the pole tide, the oceanic response to the Chandler wobble were presented. Observed North Sea pole tide enhancement (i.e., larger amplitudes than a static tide would possess) resulted from bottom friction, with the drag coefficient, in ...

Modeling Near-Surface Suspended Sediment Concentration in the English Channel

open access: yesJournal of Marine Science and Engineering, 2015
The present study investigates the performances of the three-dimensional multicomponent hydro-sedimentary model ROMS (Regional Ocean Modeling System) to predict near-surface suspended sediment concentrations (SSC) in the English Channel (western Europe).

Types of Tides and Tidal Currents [PDF]

open access: yes
This text discusses differences in ocean tides. Along America's Atlantic Coast, two high and low tides occur daily. Such tides are called semidiurnal. On the north shore of the Gulf of Mexico, the tide is diurnal, meaning that it moves in and out again ...

Nonlinear Interactions of Planetary‐Scale Waves in Mesospheric Winds Observed at 52°N Latitude and Two Longitudes

open access: yesGeophysical Research Letters
Nine‐years of mesospheric wind measurements, from two meteor radars at 52°N latitude, were analyzed to study planetary waves (PWs) and tides through estimating their zonal wavenumbers.

Numerical modelling of tides and tsunami waves propagation

open access: yesИнженерно-строительный журнал, 2018
Modelling of tides and tsunami waves propagation is important problem for the hydraulic engineering practice since it allows to predict characteristics of these phenomena (load, values of run up and flooding zones, propagation times to structures and so ...

Orbital Decay of the PSR J0045-7319/B Star Binary System: Age of Radio Pulsar and Initial Spin of Neutron Star

open access: yes, 1996
Recent timing observations of PSR J0045-7319 reveal that the neutron star/B star binary orbit is decaying on a time scale of $|\Porb/\dot\Porb|=0.5$ Myr, shorter than the characteristic age ($\tau_c=3$ Myr) of the pulsar (Kaspi et al.~1996a).

Thermal Tides in Fluid Extrasolar Planets

open access: yes, 2009
Asynchronous rotation and orbital eccentricity lead to time-dependent irradiation of the close-in gas giant exoplanets -- the hot Jupiters. This time-dependent surface heating gives rise to fluid motions which propagate throughout the planet.

The Harmonic Development of the Tide-Generating Potential

open access: yes, 1921
The harmonic development of the tide-generating potential is the basis of most work on tidal observations, and since 1883 the development given by Sir G. H. Darwin has been universally used and has been of remarkable value.
