Seasonal dynamics and the vertical stratification of multiple parameters, including water temperature (WT), dissolved oxygen (DO), pH, chlorophyll-a (Chl-a), were analyzed in Lake Chenghai, Northern Yunnan, based on monitoring data collected 2015 (October), 2016 (March, May, July), 2017 June, October), 2018 (August), 2020 (June, November). The results indicate that lake was well mixed winter sp...

Temperature–salinity profiles from the region studied in the North Atlantic Tracer Release Experiment (NATRE) show large isopycnal excursions at depths just below the thermocline. It is proposed here that these thermohaline filaments result from the mesoscale stirring of large-scale temperature and salinity gradients by geostrophic turbulence, resulting in a direct cascade of thermohaline varia...

Recent theories of the Antarctic Circumpolar Current suggest that its lateral and vertical stratification is controlled by its baroclinic instability: eddies in the ACC not only feed off the available potential energy stored in sloping isopycnals but play a central role is setting up that stratification. Simple theory makes predictions about how the depth of the thermocline in the ACC depends o...

Although the strongest ocean surface currents occur at horizontal scales of order 100 km, recent numerical simulations suggest that flows smaller than these mesoscale eddies can achieve important vertical transports in the upper ocean. These submesoscale flows, 1-100 km in horizontal extent, take heat and atmospheric gases down into the interior ocean, accelerating air-sea fluxes, and bring dee...

It is known that there is no extremal singly even self-dual [n, n/2, d] code with minimal shadow for (n, d) = (24m+2, 4m+4), (24m+4, 4m+4), (24m+6, 4m+4), (24m + 10, 4m + 4) and (24m + 22, 4m + 6). In this paper, we study singly even self-dual codes with minimal shadow having minimum weight d− 2 for these (n, d). For n = 24m + 2, 24m + 4 and 24m + 10, we show that the weight enumerator of a sin...

[1] On the basis of moored (35 W, 0 and 23 W, 0 ) and satellite observations, we contrast the upper equatorial Atlantic variability during 2002 with those during 2005. Inspection of the interannual boreal summer cold tongue variability revealed a warm (cold) event in 2002 (2005), with relaxed (intensified) winds in the west and the Equatorial Undercurrent (EUC) embedded in a shallower (deeper) ...

Hydrodynamic models were used to simulate the dispersal of a model fish pheromone at three characteristic depth regimes (mixed layer, and 300 and 1000 m) of broad extent in the open ocean at the scale of individual organisms. The models were calibrated to experimental studies of dye dispersal at these depths and the goldfish pheromone system was used as the model odorant. There are profound dif...

In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...

The Simple Ocean Data Assimilation (SODA) reanalysis (1958–2001) is used to investigate the decadal variability in the equatorial thermocline in the Pacific.Whereas the thermocline depth exhibits weak variation at decadal time scales, the temperature change in the vicinity of the thermocline in the western Pacific is significant and has a vertical scale of;150 m. Based on a modal decomposition ...
