For the tropical Indian Ocean (IO), depth of the 20掳C isotherm (hereafter referred to as D20) is a reasonable proxy for the thermocline depth. Unfortunately, this important parameter cannot be measured by sensors onboard Earth-observing satellites. In this study, this parameter was estimated ...
We have estimated the DBML (depth to the bottom of the magnetic layer) in South America from the inversion of magnetic anomaly data extracted from the EMAG2 grid. The results show that the DBML values, interpreted as the C

few studies attempt to measure patterns of beta diversity for ecological communities in the deep sea. Here we (i) present and quantify large-scale gradients in fish community structure along depth and latitude gradients of the New Zealand EEZ, (ii) obtain rigorous quantitative estimates of these ...
parts of the system.After comparing our results with the Moho depths reported by other authors, we have found that the Curie isotherm is deeper than Moho in most of the South American Platform(northward to ~20°S), which is located in the stable cratonic area at the east of the Andes....
In all these works the bottom of the crustal magnitised layer is assumed to correspond to an isotherm whose temperature is approximately the Curie temperature of pure magnetite (580 °C). Haggerty 7 cautioned against assuming a single Curie temperature for the continental crust and pointed out ...
of the magnetic bottom using a fractal method on aeromagnetic data from Vulcano, Lipari, and Salina volcanic ridge allows us to constrain the Curie isotherm depth. The elevated portion of the isotherm is between 2 and 3 km below Salina and Vulcano and about 1 km below Lipari. The Curie ...
The role of water in the nucleation process of an earthquake and its contribution to the mainshock is ascertained by many models in its physical part, as a
The depth of the 20掳C isotherm (hereafter referred to as D20) derived from expendable bathythermograph (XBT) measurements along 6掳N in the southern Bay of Bengal (hereafter referred to as the Bay) shows pronounced seasonal-to-interannual variability and profound westward propagation. But not ...
A high correlation exists between the 20掳C isotherm depth at the north equatorial countercurrent trough of dynamic topography and the monthly mean sea level at Truk Island. The meridional topography of the main thermocline depth can be used to monitor the strength of the equatorial currents, in ...
