in this research, the correlation between precipitation change in southern coasts of caspian sea and variability of sea level pressure have been analyzed by using environmental to circulation approach at time period 1339- 1383. in this respect, we make use of daily precipitation data of the 12 synoptic stations of studied area at surface data base section and prepare the time series matrix of p...

The study of the possibility of existence of the non-propagating, trapped continental shelf waves (CSWs) along curved coasts reduces mathematically to a spectral problem for a selfadjoint operator pencil in a curved strip. Using the methods developed in the setting of the waveguide trapped mode problem, we show that such CSWs exist for a wide class of coast curvature and depth profiles.

Jaydia erythrophthalma n. sp. is described from specimens collected during two recent biodiversity surveys along the east and west coasts of Luzon, Philippines. It is characterized by a first dorsal fin with eight spines, serrated posterior and crenulated ventral preopercular edges, reddish orange iris and two series of brown spots tinged in orange on the upper part of the body.

Diphyllobothriosis is reemerging because of global importation and increased popularity of eating raw fish. We detected Diphyllobothrium nihonkaiense plerocercoids in the musculature of wild pink salmon (Oncorhynchus gorbuscha) from Alaska, USA. Therefore, salmon from the American and Asian Pacific coasts and elsewhere pose potential dangers for persons who eat these fish raw.

The decapod Grapsus grapsus is commonly found on oceanic islands of the Pacific and Atlantic coasts of the Americas. In this study, a simple, quick and reliable method for detecting its larvae in plankton samples is described, which makes it ideal for large-scale studies of larval dispersal patterns in the species.

Specific project objectives include: 1) investigating the physical processes that lead to the formation, evolution, and dissipation of offshore fog; and 2) investigating the diurnal variability of the dynamics and cloudiness of the marine atmospheric boundary layer off the California and Oregon coasts. The project is supported by the Office of Naval Research, Marine Meteorology and Atmospheric ...

For the first time, we previously recorded an enormous population of the Cassiopea andromeda jellyfish that had increased dramatically from Bushehr coasts of Iran. The sub-acute toxicity of the jellyfish venom in rat organs was correspondingly carried out. The data presented in this paper relate to the in vivo and in vitro hematological effects of this venomous species of jellyfish venom.

With rising sea levels and environmental problems caused by population and economic pressures colliding at the world's coastlines, there are huge risks to people and the environment, but also opportunities to restore natural defences and help both. Michael Gross reports.

Harmful benthic microalgae blooms represent an emergent phenomenon in temperate zones, causing health, ecological and economic concern. The main goal of this work was to compile records of Ostreopsis at large temporal and spatial scales, in order to study the relationship between cell abundances, the periodicity and intensity of the blooms and the role of sea water temperature in 14 Spanish, Fr...

Fuzzy Logic (FL) and fuzzy sets in a wide interpretation of FL (in terms in which fuzzy logic is coextensive with the theory of fuzzy sets, that is, classes of objects in which the transition from membership to non membership is gradual rather than abrupt) have placed modelling into a new and broader perspective by providing innovative tools to cope with complex and ill-defined systems. The are...
