“…It has been commented on for many years in global and regional sea-level analyses (e.g. Gutenberg, 1941;Barnett, 1984;Metreveli et al, 1985), and this inflexion is a major contributor to the positive average acceleration reported by CW06.…”

ABSTRACT:A modification in the rate of change of sea level (i.e. an 'acceleration' or 'nonlinear trend') is an important climate-related signal, which requires confirmation and explanation. In this study, the evidence for accelerations in regional and global average sea level on timescales of several decades and longer is reviewed by inter-comparison of the recent findings of different researchers and by inspection of original tide gauge records. Most sea-level data originate from Europe and North America, and both the sets display evidence for a positive acceleration, or 'inflexion', around 1920-1930 and a negative one around 1960. These inflexions are the main contributors to reported accelerations since the late 19th century, and to decelerations during the mid-to late 20th century. However, these characteristic features are not always found in records from other parts of the world. Although some aspects of the sea-level time series are consistent with changes in rates of globally averaged temperature changes, volcanic eruptions and natural climate variability, modelling undertaken so far has been unable to describe these features adequately. This emphasizes the need for a major enhancement of the sea-level data set, especially for those parts of the world without long tide gauge records, in order to obtain greater insight into the spatial dependence of accelerations. A number of complementary methods must be employed, of which salt marsh techniques offer the possibility of obtaining time series similar to those that would have been obtained from coastal tide gauges.

“…Most auth<?~ties are agreed that on the average over the globe, sea level IS at present nsmg everywhere by about 10 cm per century, this increase being produce~ mainly by the general increase in world temperature this century . (Cl~.rtwnght 1963; see also, for example, Gutenberg 1941). This then might mdicate that the land near the tide gauge site at Wellington is rising by about 0.15 cm yr"l and that at the Auckland tide gauge site is sinking at about 0.05 em yr-l.…”

The relative sizes of the factors contributing to the vanatIOns in mean sea level around New Zealand are examined. The oceanographic influence (specifically, changes in density and the oceanic circulation) appears to produce the largest variation, with ranges of the order of 10-20 em yr- •With an expected eustatic change of the order of 0.1-0.2 cm yr-1 long-term accurate sea-level records of at least 15-20 years are needed to allow accurate estimates of the eustatic and tectonic changes.

“…Stations on the south flank of the San Gabriel Mountains are rising at a rate of 20 feet per 1,000 years. Gutenberg (1941) has compiled information on postglacial uplift in Fennoscandia and North America. Maximum uplift at the head of the Gulf of Bothnia is 110 centimeters per 100 years or 36 feet per 1,000 years.…”

“…Present rates of uplift in North America are 50 centimeters per 100 years to the north of Lake Superior, a rate of 16 feet per 1,000 years. Gutenberg (1941) estimates that present rates of uplift average about half the average for the past 4,000 years. Uplift of about 500 meters has occurred and an additional uplift of 200 meters is required to establish equilibrium.…”
