New estimates are obtained of oxygen utilization rates on isopycnal surfaces in the North Atlantic subtropical gyre thermocline based on tritium inventories (2.4-3.5 mol m -2 yr -1) and 228Ra measurements (8.5 _+ 0.8 mol m -2 yr-l). Arguments are given for why the tritium inventory oxygen utilization rate estimate may be too low. The 228Ra results are combined with recent estimates of oxygen ut...

mixed layer is a part of the atmospheric boundary layer in which pollutants are uniformly distributed. it is sensitive to the earth’s surface, controls the flow of heat and momentum between the surface and the free atmosphere, thus playing a key role in atmospheric circulation. most of atmospheric pollution models require the height of the mixed layer as an input to determine the depth of atmos...

The Japanese eel, Anguilla japonica, spawns within the North Equatorial Current that bifurcates into both northward and southward flows in its westward region, so its spawning location and larval transport dynamics seem important for understanding fluctuations in its recruitment to East Asia. Intensive research efforts determined that Japanese eels spawn along the western side of the West Maria...

Using the vertical temperature profiles of Lake Qiandaohu from January 2010 to April 2013, we evaluated the monthly and seasonal variations of water temperature and thermocline parameters, and developed empirical models among thermocline depth (TD), thickness (TT), and strength (TS). We also developed empirical models between TD, TT, TS, and surface-water temperature (0–2 m) (T0–2 m), and trans...

[1] Enhanced phytoplankton biomass in the wake of the Galápagos Islands is thought to result from an island-mass effect (IME) fueled by upwelling of the Equatorial Undercurrent (EUC) and by natural iron enrichment from the island platform. Annual means of five variables describing the thermocline, the pycnocline, and the availability of nitrate at the surface were derived from the World Ocean A...

The issues of the formation and temporal variability vertical structure Black Sea waters off coast southern Crimea are considered. A large array instrumental measurement data obtained in second half 2013 (June–December) during operational monitoring temperature profile area Stationary oceanographic platform Marine Hydrophysical Institute coastal zone near Cape Kikineiz is used. measurements wer...
