In the present study, a trophic structure model for some fish species of the northern Oman Sea is developed through using mass balance modeling software, Ecopath with Ecosim (EwE). In this model, we simulated 16 functional groups spread across an area of 3998.20 km2 from 2017 to 2018. Mean trophic level in the area of the present study was 3.49. Values calculated for system omnivory and connect...

Background: The aim of this study is to measure the level of radon gas in the thermal springs of the four seasons in the Black Sea Region and to determine the gamma activity levels in the soils around them. Materials and Methods: Indoor radon activity concentrations of four spa facilities, namely Ladik, Havza, Ilıcaköy, and Ayder, were measured using CR-39 passive radon dosimeters and active ra...

Sea surface temperature (SST) is a key factor for both climate and weather. Most studies focus on evaluation of satellite SSTs in different oceanic regions, but the performance ERA5 reanalysis SST datasets (ERA5 SSTs) has not been systematically evaluated. In this article, buoy measurements from 46 National Data Buoy Center (NDBC) sites around Pacific Atlantic are used to make an analysis devia...

caspian region is on the receiver of caspian sea with five coastal states including of iran, russia, azerbaijan, turkmenistan and kazakhstan - in the surrounding sea, due to having common points in the features of natural geography, special location, political and cultural and historical background, is known as a geopolitical region. following the collapse of the soviet ::::union::::, due to ch...

During the Austral summer of 2006–07 a series of extreme oceanic events occurred in the Tasman Sea. Following a series of strong wind-driven upwelling events, an intense cold-core eddy developed off Sydney, Australia. A data-assimilating, eddy-resolving ocean model is used to create a threedimensional time-varying reanalysis of these events. The reanalysis indicates that the cold anomalies asso...

introduction a considerable percentage of the world’s population is living in the coastal areas. thus, there are many different kinds of problems in these regions. because of the large amount of the people in these areas, their ecosystems are confronted with huge and serious problems. there are different types of arrangements for preventing destruction of ecosystems around the seas. unified man...
