| Summary: | The sea level rise of the Chesapeake Bay region
of the East Coast of the United States is claimed to be
greater than the worldwide rate, where this latter is assumed
to be given by the short term satellite global mean sea level
computation. These Chesapeake Bay values are obtained
by linear fitting of the last few years of local tide gauge
measurements. It is shown that this short term evaluation
of the local sea level rises does not permit to compute the
long term trend cleared of the Atlantic multi decadal oscillations.
This paper clarifies the relevance of 60 years multi
decadal oscillation for the tide gauges of the area and shows
that the present short term sea level rises are not larger than
those previously measured with the same technique. These
short term sea level rises do not represent the longer term
trend but also include the multi decadal oscillation of period
quasi-60 years. The present sea level velocity in the
area of Chesapeake Bay is assessed at about 3.5 mm/y with
no positive component of acceleration. |
