When a storm tide coincides with an exceptionally high astronomical tide and shallow water depths, the results may be catastrophic. The record of storm tides is knowable, and they may be predictable in the Gulf of Maine-Bay of Fundy region. The AA
. begin with a look at some of the events associated with the most historically memorable Fundy storm tide, the Saxby Tide of 4-5 October 1869.
Variability of the tide at some sites in the Canadian Arctic
Various techniques are used to detect the possible distortion of the tide by the presence of an ice cover at some gauging sites in the Canadian Arctic. Some stations are apparently unaffected, while those around the periphery of Amundsen Gulf
and Hudson Bay experience larger tides during the annual period of open water and the time of arrival of the tide is altered.

Tide measurements by independent instrumental systems. The relations between the absolute and relative accuracy are discussed. Comparison with tide parameters of a basis station. Agreement in the framework of expectable tolerances. (HL).

Determination of the land uplift from old water marks and tide gauge data at Ratan and Lovgrundet/Bjorn, Sweden
Old water marks (the oldest from 1731) are combined with more recent tide gauge data at Ratan and Lovgrundet/Bjorn in Sweden in an analysis of the land uplift. The study shows that the hypothesis of a significant change of the uplift rate
at the beginning of this century cannot be verified. Furthermore, the tide gauge data does not support a decrease of the uplift rate.
Secular trends of relative sea-level (RSL) changes indicated by tide-gauge records
Divergent trends of secular sea-level changes are shown by 229 tide-gauge stations with long enough records. No region of the world can be said stable, even on the tide scale of a few decades. Tectonic and oceanic factors are more important than
In this paper, the first gravity values at 16 Norwegian stations measured by a modern absolute gravimeter of the FG5 type are presented. The gravity observations were corrected for Earth tides, varying atmospheric pressure, polar motion, and ocean
tide loading. The ocean tide loading corrections were subject to special attention. A model based on locally observed ocean tides was applied at some of the stations. The authors estimated the total uncertainties of the gravity values to range from 3
Acid sulphate soil-landscape relationships in an undrained, tide-dominated estuarine floodplain, Eastern Australia
This paper deals with the case of a tide-dominated estuarine system. The study site is an undrained floodplain with limited human disturbance. This will also provide an opportunity for the examination of pure natural controls on the genesis of acid
Response of tide-dominated mangrove shorelines in Northern Australia to anticipated sea-level rise
This paper examined the characteristics of tide-dominated mangrove shorelines in northern Australia, and suggests a framework, based upon morphodynamics, within which to view their response to a rise in sea level. Within this paper the response

The results showed that the tide-induced Lagrangian Residual Circulations, LRC, of the harmonic constituent M2 bears an identical pattern in 4 seasons in the Bohai Sea : the surface one is weak with random directions; however, there exist
a southeast current from the Bohai Strait to the Laizhou bay, and a weakly anticlockwise gyre in the south of the Bohai Strait for the bottom layer LRC. The magnitude of bottom layer tide-induced LRC is larger than the surface one, and moreover, it conributes
significantly to the whole LRC in the Bohai Sea. Unlike the identical structure of the tide-induced LRC, the wind diven LRC varies seasonally under the prevailing monsoon.
change were identified, mainly associated with maximum tidal levels : 1) berm accretion during calm wave conditions (tidal range moved from neap to spring tide); 2) berm retreat and erosion in relation to sediment supply and wave conditions (tidal range
still moving towards spring tide); 3) berm reconstruction and seaward progradation followed by stability (through the spring tide and approching the neap tide). Cusps occurred twice indicating the reflective nature of the beach. The method used

Analysis of historical survey and navigation charts, aerial imagery, and digital hydro-data (representing a time-series of 1889-2009) allows the morphological evolution of a flood-tide delta at the artificial entrance to the Gippsland Lakes
(Victoria, Australia) to be visualised and quantified. The analysis shows that the flood-tide delta growth corresponds with a progressive diminution of Gippsland Lakes catchment river discharge volumes, and dampening of flow variability, due to both regional

Estimate of long-term sediment discharge at tidal inlets using water level data from a tide gauge
to this approach, a time-series of water level data from a single tide gauge located at a harbour entrance, together with data sets for wave climates and freshwater discharges, can be analysed to estimate sediment discharges. An example of the application

Two mathematical models for the study of mesoscale (tides, storm, surges, ...) and macroscale (general circulation...) motions are described. The mesoscale model is applied to the simulation of the M2 tide on the North-Western European Continental
The salinities of tide water and sediments from the northern and the southern sectors of the coastal marshes are compared. In the north, Bay water of relatively high salinity is introduced to the marsh by tides, as is generally found in coastal
