Open AccessA likely role for stratification in long-term changes of the global ocean tides
Stratification—that is, the vertical change in seawater density—exerts a subtle control on the energetics and thus the surface elevation of barotropic (depth independent) flows in the ocean. Changes in stratif...

Wave setup at the Minamitorishima tide gauge
A tide gauge situated on the western shore of Minamitorishima, a small atoll in the western Pacific, has measured sea levels significantly impacted by wave setup. Evidence for this rests with (a) strong correl...

Open AccessThe mean seasonal cycle in relative sea level from satellite altimetry and gravimetry
Satellite altimetry and gravimetry are used to determine the mean seasonal cycle in relative sea level, a quantity relevant to coastal flooding and related applications. The main harmonics (annual, semiannual,...

Open AccessForcing Factors Affecting Sea Level Changes at the Coast
We review the characteristics of sea level variability at the coast focussing on how it differs from the variability in the nearby deep ocean. Sea level variability occurs on all timescales, with processes at ...

Open AccessA fortnightly atmospheric ‘tide’ at Bali caused by oceanic tidal mixing in Lombok Strait
Strong tidal currents in and around the narrow straits of the Lesser Sunda Islands, Indonesia, affect ocean sea surface temperatures (SST) via non-linear tide-induced mixing. A fortnightly spring–neap cycle in...

One centimeter-level observations of diurnal ocean tides from global monthly mean time-variable gravity fields
A method of analyzing GRACE satellite-to-satellite ranging data is presented which accentuates signals from diurnal ocean tides and dampens signals from long-period non-tidal phenomena. We form a time series o...

Bottom pressure tides along a line in the southeast Atlantic Ocean and comparisons with satellite altimetry
Seafloor pressure records, collected at 11 stations aligned along a single ground track of the Topex/Poseidon and Jason satellites, are analyzed for their tidal content. With very low background noise levels a...

Map** nonlinear shallow-water tides: a look at the past and future
Overtides and compound tides are generated by nonlinear mechanisms operative primarily in shallow waters. Their presence complicates tidal analysis owing to the multitude of new constituents and their possible...

Continuation by integral equation methods: A note on surface integration over the double layer
Upward continuation from a non-level surface may be performed by an integral equation method as shown previously by Bhattacharyya and Chan. Integration over the double layer is often computed using a centroid ...
