Última Zooplankton-climate linkages in different geographical regions IBSS Repository Piontkovski, S. A.; Hameed, S.. The inter-annual variations of total zooplankton abundance in the Gulf of Maine (1961 ‑ 1991), the North‑East Atlantic (1961 ‑ 1994) and the North Sea (1961 ‑ 1994) were analyzed and related to the Icelandic Low and the Azores High atmospheric pressure systems. In a similar way the variations of zooplankton biomass in the Gulf of Alaska (1956 ‑ 1980) were related to the Aleutian Low pressure system. Cross‑correlation and spectral density functions were calculated for the zooplankton and the pressure indices. Regional and global aspects of the relationship between the intensity of the zooplankton fluctuations and the atmospheric centers of action were analyzed. A discussion on possible mechanisms that may contribute to the dynamic links transferring...

Ano: 2004 URL: http://repository.ibss.org.ua/dspace/handle/99011/131 Observing and Studying Extreme Low Pressure Events with Altimetry ArchiMer Carrere, Loren; Mertz, Francoise; Dorandeu, Joel; Quilfen, Yves; Patoux, Jerome. The ability of altimetry to detect extreme low pressure events and the relationship between sea level pressure and sea level anomalies during extra-tropical depressions have been investigated. Specific altimeter treatments have been developed for tropical cyclones and applied to obtain a relevant along-track sea surface height (SSH) signal: the case of tropical cyclone Isabel is presented here. The S- and C-band measurements are used because they are less impacted by rain than the Ku-band, and new sea state bias (SSB) and wet troposphere corrections are proposed. More accurate strong altimeter wind speeds are computed thanks to the Young algorithm. Ocean signals not related to atmospheric pressure can be removed with accuracy, even within a Near Real Time...
