seasonal variations of the seawater properties (e.g. temperature, salinity, density and chlorophyll-a) in western part of the southern coastal waters of the caspian sea near the iranian coast were studied. a portable ctd probe was applied for profiling from sea surface to bottom at 23 stations. maximum depth of the profiling stations was more than 470 m in the study area. vertical structure of ...

We used acoustic telemetry to investigate the roles of depth and temperature in daytime foraging behaviours 13 tagged pelagic thresher sharks by monitoring their fine scale vertical movements Philippines. Cumulatively, shark dives traversed entire water column where they encountered temperatures that ranged from 33°C at surface 12°C 250 m depths throughout day, but individuals varied extent bot...

[1] An ocean model is used to test the idea that sea surface DC behaves as a thermocline proxy in the eastern equatorial Pacific. The ORCA2 model, which includes DC as a passive tracer, has been forced with reanalysis fluxes over 1948–1999, and the output is compared with a previously reported Galapagos DC record. The model reproduces the abrupt increase in the seasonally minimum DC in 1976/77 ...

Abstract The currents of gyre (circulation) flow play an important role in the transportation and mixing dissolved or suspended nutrients chemical substances. In recent years, climate change has affected field Lake Biwa. However, how much can influence not been clarified enough yet. present study, using a three-dimensional hydrodynamic model, we investigated effect changes air temperature, wind...

Vertical variability of inherent optical properties (IOPs) affect the water quality retrievals from remote sensing data. Here, we studied vertical IOPs and simulated apparent (AOPs) in Gulf Finland (Baltic Sea) under three characteristic (non)stratification conditions. In case mixed column, optically significant constituents (OSC) was relatively small. While stratified column surface layer were...

sensitivity of upper thermocline properties to tropical cyclone winds and possible feedbacks on the Hadley circulation" (2010). [1] The sensitivity of upper thermocline properties, and global climate, to tropical cyclone (TC) winds is examined using global ocean and atmosphere general circulation models. We combine seven years of global, satellite‐based TC wind records with a standard surface w...

A reduced-gravity, primitive-equation, upper-ocean general circulation model is used to study the mean water pathways in the North Pacific subtropical and tropical ocean. The model features an explicit physical representation of the surface mixed layer, realistic basin geometry, observed wind and heat flux forcing, and a horizontal grid-stretching technique and a vertical sigma coordinate to ob...

We measured the horizontal and vertical movements of ®ve adult yellow®n tuna (Thunnus albacares, estimated body mass 64 to 93 kg) near the main Hawaiian Islands, while simultaneously gathering data on oceanographic conditions and currents. Fish movements were recorded by means of ultrasonic depth-sensitive transmitters. Depth±temperature and depth±oxygen pro®les were measured with vertical cond...
