Long-term, global sea level depends on the balance of water fluxes between Earth's mantle and surface: between mantle degassing through volcanism and mantle regassing via the subduction of hydrous minerals. However, the overall balance of these fluxes at geological timescales remains uncertain. ...
First-order changes in global sea level are commonly thought to be the result of short-term fluctuations in oceanic spreading rate. However, eustatic high stands have occurred only twice in Phanerozoic time, and in both cases have followed supercontinent break up by a lag period of 50–100 Ma...
Sea-level changes on a wide range of time and space scales. Here we consider changes in mean sea level, that is, sea level averaged over a sufficient period of time to remove fluctuations associated with surface waves, tides, and individual storm surge events. We focus principally on changes...
The rate of global-mean sea-level rise since 1900 has varied over time, but the contributing factors are still poorly understood. Previous assessments found that the summed contributions of ice-mass loss, terrestrial water storage and thermal expansion of the ocean could not be reconciled with obs...

“Others” denotes taxa with relative abundances below the cut-off level of 5%. Inner bars in the Gammaproteobacteria indicate the relative abundances of three families, further characterized by pairwise metagenomic data. d, e Non-metric multidimensional scaling (NMDS) ordination of bacterial ...
4.1 Sea level rise and land-sea change along Bohai Bay over 10 ka Before launching the case study, we should first understand the basic conditions such as changes in the sea level and coastline throughout geological time. The relative sea level in the area of Bohai Bay is around −15 ...
2013) that this is prone to decimetre-scale errors at the scale of Great Britain (GB), and the periodic relevelling exercises and changes of chosen reference will introduce artificial time dependence in the sea level record. However, levelling over shorter distances is much more reliable, as ...

“This is really important as it confirms the pace of glacier melting is accelerating over time,” said Prof Andrew Shepherd, head of the department of geography and environmental science at Northumbria University. “Even small amounts of sea level rise matter because it leads to more frequent ...
