The DO-climate events are probably noise induced: statistical investigation of the claimed 1470 years cycle
The significance of the apparent 1470 years cycle in the recurrence of the Dansgaard-Oeschger (DO) events, observed in the Greenland ice cores, is debated. Here we present statistical significance tests of this periodicity. The detection of a periodicity relies strongly on the accuracy of the dating of the DO events. Here we use both the new NGRIP GICC05 time scale based on multi-parameter annu...

متن کاملLimitations of red noise in analysing Dansgaard-Oeschger events
During the last glacial period, climate records from the North Atlantic region exhibit a pronounced spectral component corresponding to a period of about 1470 years, which has attracted much attention. This spectral peak is closely related to the recurrence pattern of DansgaardOeschger (DO) events. In previous studies a red noise random process, more precisely a first-order autoregressive (AR1)...

Abstract Background: Noise-induced hearing loss is among the most common occupational diseases and is completely preventable despite being permanent and irreversible. Although management and engineering control are in prior, for some reasons its implementation is difficult in certain circumstances. So, Hearing Protection Devices (HPDs) are often the only method. But most of workers exposed to ...
متن کاملInvestigation of wind induced wave climate close to the Koohmobarak Area, Gulf of Oman
Abstract Wind induced wave is of great importance due to its high energy. In this study wave climate in the Gulf of Oman close to the Koohmobarak area is investigated. Wave climate study is necessary for determination of long-term analysis of wave statistics as well as climate change effects in the study area. First, wave climate is study using both measured and simulated wave data close to th...
