It is now firmly recognized that although the majority of mammalian genome is transcribed to RNA, protein-coding transcripts occupy only a minor part of mammalian transcriptome. Instead, increasing evidence suggests that the majority of mammalian RNAs is comprised noncoding RNAs (ncRNAs). ncRNAs are a diverse class of RNAs with many subclasses involved in a wide variety of physiological functio...

A tidal bore is a surge of water propagating upstream as the tidal flow turns to rising into an estuary with a tidal range larger than 5 to 6 m and a bathymetry that amplifies the tidal wave. The bore front is a shock characterised by a singularity of the free-surface and pressure and velocity fields. This study aims to characterise the tidal bore propagation and the induced turbulent mixing un...

The approach is to incorporate latest developments in turbulence and tidal research and modeling into ROMS. This project complements well, the AESOP program, the ONR DRI on subgrid-scale parameterization and skill assessment of numerical ocean models as well as the new Characterization and Modeling of Archipelago Strait Dynamics (CMASD) DRI. Using the Adriatic Sea (and North Indian Ocean) ROMS/...

Aims. This paper aims to study the configuration of two components caused by rotational and tidal distortions in the model of a binary system. Methods. The potentials of the two distorted components can be approximated to 2nd-degree harmonics. Furthermore, both the accretion luminosity (σi) and the irradiative luminosity are included in stellar structure equations. Results. The equilibrium stru...

Enhanced tidal streams close to coastal headlands appear to present ideal locations for the deployment of tidal energy devices. In this paper, the power potential of tidal streams near an idealized coastal headland with a sloping seabed is investigated using a near-field approximation to represent a tidal fence, i.e. a row of tidal devices, in a two-dimensional depth-averaged numerical model. S...

We use an observational data set of tidal gauges in the North Sea to investigate the annual cycle of the M2 and M4 amplitudes and phases. The sea surface elevation amplitude of the M2 can vary by 8–10% and the M4 amplitude by 12–30% over the course of the year, with larger amplitudes in summer. The annual phase variations are in the range of 3–15◦. The reason for these variations is the thermal...

Tidal creeks are small estuarine watersheds characterized by low freshwater input, marine to brackish salinity, and subtidal, intertidal, and supratidal habitats. Most people are familiar with large rivers and estuaries, but the smaller tidal watersheds comprise a greater percentage of the coastline. As the population along coasts rises there is growing concern about water quality and increased...

Please cite this article in press as: Stuhne Ocean Modell. (2009), doi:10.1016/j.ocem In an earlier work, we described how an unstructured grid numerical framework based on an energy-conserving Arakawa C-grid discretization could be applied to ocean general circulation models (OGCMs). We discuss herein how we adapted our previously published rigid-lid, hydrostatic, Boussinesq OGCM techniques to...

Ocean surface current measurements from high-frequency (HF) radar are assessed by comparing these data to near-surface current observations from 1 to 30 October 1994 at two moored subsurface current meter arrays (20 and 25 m) instrumented with vector-measuring current meters (VMCMs) and Seacat sensors during the Duck94 experiment. A dual-station ocean surface current radar (OSCR) mapped the cur...
