The racks slide into frames that are supported by the "ISOBase" platform with the Ball-N-Cone system, seismarack.com
Offered with a sensitivity of 3pC/g, it features Meggitt's proprietary piezoelectric-elements and Isobase construction, to provide mechanical isolation of the sensing assembly from the mounting surface and minimise base strain.
Offered with a sensitivity of 3 pC/g, Model 2280 features proprietary piezoelectric elements and patented Isobase construction to provide mechanical Isolation of the sensing assembly from the mounting surface and to minimize base strain.
Naturally, this value is valid only for the accumulative silt sediments in the deeper area of the lake, mostly contoured by the 9-11 m isobase. There is a zone with stable accumulation of sedimentary material originating from the Piirissaar glaciofluvial delta.
In the Parnu district, which lies on the same isobase as Narva, one Litorina transgression was recognized (Veski et al.
Although the Olsen site is not on the same isobase as Silver Lake, additional data points from Silver Lake (this study) can be added to the Lake Michigan lake level curve to better reconstruct the Nipissing transgression.
A compilation by the first author of isobase maps (based on published sea-level data for Atlantic Canada) shows relative sea level rapidly dropped from +45 m, reached +5 m (the level of the modern lake) by ca.
Offered with a sensitivity of 3 pC/g, the model features Meggitt's proprietary piezoelectric elements in the patented Isobase construction, providing mechanical isolation of the sensing assembly from the mounting surface, minimising base strain.
Tilting of shorelines is the result of a more intensive uplift of the northern part of the lake, through which runs also the zero isobase of the land uplift for the last 10 000 years (Fig.
Clark and Fitzhugh (1992) have developed isobase maps for Labrador covering the time period from 7000 to 3000 B.P.; they point out, however, that the coastal zone between 51[degrees]N and 54[degrees]N, essentially the LSCS survey zone, constituted a major gap in their coverage.
