it is well known that, contaminant transportation is a major problem in coastal zones and has to be faced when coastal structures are being planned. sea pollution not only causes environmental damage, but also impacts quality and population of sea resources. oil is the most important pollutant, pollutants emanating from industries, ships, drilling and exploration in the seabed, ship sewage, tox...

in recent years, several ocean tide models have been used to calculate tides using data of satellite and tide gauges data. global ocean tide models have many applications in various sciences such as geophysics, geology and geodesy and oceanography. considering­ the existence of many models, a quantitative evaluation of research, and ranking and selecting the best model of the global ocean tide ...

Abstract The features of tide and tidal current in the east China seas were studied by FES2014 data gauge station data. It is found that well agreement with observation. Among four major components (M2, S2, K1, O1), M2 strongest component maximum amplitude (tidal current) exceeds 100 cm (100 cm/s), followed S2 its reaches 60 (50 cm/s). results indicate are dominated semi-diurnal tides. There am...

based on 11 years of topex/poseidon satellite altimetry and coastal tide gauge sea level observations, four tidal constituents, namely o1, k1, m2 and s2, are modeled for the persian gulf and oman sea using a time-wise approach according to the following details. by selecting the cycle 100 as the reference, 772 points on 12 paths along the track of the altimetry satellite footprints over the per...

Tides and their dynamic processes in the South China Sea (SCS) are studied by assimilating Topex/Poseidon altimetry data into a barotropic ocean tide model for the eight major constituents (M2 S2 K1 O1 N2 K2 P1 Q1) using a tidal data inversion scheme. High resolution ( 10 km) and large model domain are adopted to better resolve the physical processes involved and to minimize the uncertainty fro...

An analysis of current profiles carried out on moored Acoustic Doppler Current Profiler data sets recorded during the Variability of Exchanges In the Northern Seas project is presented here for several locations in three sections in the vicinity of the Iceland-Scotland Ridge: (1) north of the Faroes, (2) in the Faroe-Bank Channel and (3) in the Faroe-Shetland Channel. Total currents have been d...

Eight major tidal constituents in the Sea of Okhotsk have been investigated using a numerical solution of tidal equations on a 59 space grid. The tides are dominated by the diurnal constituents. Diurnal tidal currents are enhanced in Shelikhov Bay and Penzhinskaya Guba, at Kashevarov Bank, in proximity to the Kuril Islands and at a few smaller locations. The major energy sink for diurnal tides ...

[1] A high-resolution hybrid data assimilative (DA) modeling system is used to study barotropic tides and tidal dynamics on the southeast New England shelf. In situ observations include tidal harmonics of 5 major tidal constituents [M2, S2, N2, O1, and K1] analyzed from coastal sea level and bottom pressure gauges. The DA system consists of both forward and inverse models. The former is the thr...

The stationarity of the internal tides generated in a global eddy-resolving ocean circulation model forced by realistic atmospheric fluxes and the luni-solar gravitational potential is explored. The root mean square (RMS) variability in the M2 internal tidal amplitude is approximately 2 mm or less over most of the ocean and exceeds 2 mm in regions with larger internal tidal amplitude. The M2 RM...

[1] Surface tidal circulation over the continental shelf of Duck, North Carolina, was explored using surface current observations measured by a high-frequency (HF) radar. The Ocean Surface Current Radar (OSCR) was deployed at the U.S. Army Corps of Engineers (USACE) Field Research Facility (FRF) in Duck, North Carolina, during 1–30 October 1994 and measured surface current at 20-min intervals a...
