Abstract

Estimation of the homogeneity of long-term temperature series and seawater salinity at change in methods and time of their observations at the sea station of the Far Eastern coastal network. N.G. ALISIMCHIK1, S.I. KISLOVA1,2 ( 1Far Eastern Regional Hydrometeorological Research Institute, Vladivostok, 2Far Eastern State Technical Fisheries University, Vladivostok).

The statistical estimation of the homogeneity of long-term series of temperature and seawater salinity was carried out when changing the methods, timing and places of their measurement at the stations of the Far Eastern coastal network.
For the water temperature, two factors have been identified that violate the homogeneity of long-term observation series – a shift in the standard observation time and a shift in the observation place.
Two main factors of the homogeneity disruption of long-term series of seawater salinity have been established: the absence of synchronous observations when switching from one method to another one and GM-65 error when its operation exceeds the calibration interval.
