| Daily time series of in-situ tide gauge records and river runoff data were analysed to investigate the contribution of river discharge storm events to sea level in the Bay of Biscay. Three main river systems were considered for this study, representing cases of small (Nervión, 1900 km2), medium (Adour, 16880 km2) and large (Gironde, 84811 km2) watershed basins. Typical storms correspond to water discharge rates of 150, 700, and 1100 m3 s−1 from the Nervión, Adour, and Gironde rivers, respectively. The effect of these events on daily mean sea level was evaluated using two different approaches: (1) through the analysis of time series of tide gauges placed within the river mouths; and (2) through numerical simulations using the ROMS model (Regional Ocean... |

| This manual is concerned primarily with techniques for the measurement of what are called relative sea level changes which means changes relative to the level of the land upon which the measuring instrument (the tide gauge) is located. The subject of changes in the level of land itself is reviewed later in this document but is given more detailed presentation in other reports to which we refer. The manual also concerns itself primarily with the part of the frequency spectrum of sea level change from minutes through to centuries by means of in situ devices at the coast (tide gauges). Such changes are sometimes called still water level changes, being changes over a period long enough to average over wind waves. The devices employed to make these measurements... |

| Tide gauge measurements recorded at two stations in the Red Sea, at Port Sudan from 1986 - 1994 and at Gizan for the period of 1992 - 1994 are used to analyze the sea level changes and tide along the east and west coast of the Red Sea, using the harmonic analysis (t tide). Meteorological parameters during the same period are used to study the response of the sea level and residual sea level to local and global forcing. The relation between sea level and forces are examined using the correlation and cross covariance analysis. The correlation and cross-covariance coe cients between sea level and sea level pressure at Port Sudan indicate that the sea level responds to atmospheric pressure as non-inverse barometer. The linear trend for the coastal area shows a... |

| This paper describes the assembly of an updated quasi-global dataset of higher-frequency sea level information obtained from tide gauges operated by many agencies around the world. We believe that the construction of such a dataset is fundamental to scientific research in sea level variability and also to practical aspects of coastal engineering. A first version of the dataset was used in approximately a dozen published studies, and this second version is about twice the size, containing longer and more geographically representative sea level records. The dataset has acquired a digital object identifier and may be obtained from several sources. The paper mentions some of the merits of and deficiencies with the present version and takes a forward look at... |
