High-resolution (2 km) high-frequency (hourly) SST data from 2015–2020 provided by the Advanced Himawari Imager (AHI) onboard Japanese Himawari-8 geostationary satellite positioned over 140.7°E were used to study spatial and temporal variability of China Coastal Front (CCF) in East Sea. This dataset was processed with Belkin O’Reilly algorithm generate long-term mean monthly maps gradient magni...

The coastal plain of the Rio Grande do Sul state (RS) in southern Brazil, has an enormous lagoon complex in its southern portion formed by Patos Lagoon, Mirim Lagoon, Mangueira Lagoon and several other smaller lakes. This system was originated from successive transgression and regression cycles, which took place since the upper Pleistocene (Vilwoock, 1984). Patos Lagoon is a huge chocked lagoon...

extended abstractintroductiontoday, large number of world’s major cities is located in coastal environments these towns have and all important positions in the economic, cultural and social functions. coastal areas and the cities located in they are economically very important in terms of the environment, sensitive to many of factors influencing and physically, against a variety of natural haza...

A series of laboratory experiments on the chemical composition of aerosol particles formed after photodissociation of CH212, a major volatile alkyl halide released from macroalgae, have been performed in a laboratory scale reaction chamber using on-line atmospheric pressure chemical ionization mass spectrometry (APCI/MS). Based on the mass spectrometric results and the molecular properties of i...

We identify effective carriers of Sargassum in the Caribbean Sea and describe a mechanism for coastal choking. Revealed from satellite altimetry, are mesoscale eddies (vortices 50-km radius or larger) with coherent material (i.e., fluid) boundaries. These observer-independent—unlike eddy boundaries identified instantaneously closed streamlines altimetric sea-surface height field—and furthermore...

Coastal aquifers involve varying conditions in time and space, owing to the occurrence of free and moving boundaries, such as the water table, seepage face and saltwater intrusion interface. A fast Updating Procedure (FUP) is developed for solving these interfaces in steady and transient conditions with the finite element method. Several test examples, which involve confined and phreatic ground...

Horizontal Lagrangian surface transport is studied in the Ria de Vigo, an estuary in NW Spain with tidal and wind-driven dynamics. Surface drifters and the surface flow from a high-resolution 3-D hydrodynamic model are compared to each other. In particular, our analysis is based on a classical comparison of real and artificial trajectories and on Lagrangian Coherent Structures (LCS) defined as ...

BACKGROUND Estuaries are highly productive ecosystems that can export organic matter to coastal seas (the 'outwelling hypothesis'). However the role of this food resource subsidy on coastal ecosystem functioning has not been examined. METHODOLOGY/PRINCIPAL FINDINGS We investigated the influence of estuarine primary production as a resource subsidy and the influence of estuaries on biodiversit...

The work is devoted to the method of multispectral space images analyzing aquatic coastal systems for identifying phytoplankton populations complicated structures: determining their boundaries, distributing color gradations and, based on this, distribution concentrations within patches and location "mass" center. A combination local binary patterns (LBP) neuralnetworks methods considered. Due t...

From Oligocene to Recent times a series of tectomcally controlled coastal embayments fonned on the Pacific fore-arc side of the southern Central American island-arc system. Each of these basins shows characteristic stratal geometries and facies distributIOns reflecting the complex interaction of changes of sea level. volcaniclastic input. and tectonic activity (subsidence, uplift). Sequential s...
