According to Equation 14.1, the eustatic sea-level changes as well as the vertical crustal movements. The eustatic change is regarded constant over the whole area. Hupfer et al. (2003) propose a local eustatic rise of l.Omm/year for the last century within the western Baltic Sea. The vertical crustal movements show remarkable differences over the entire Baltic Sea area (Fig. 14.3), reflecting here the glacioisostatic adjustment (GIA). The center of uplift is in the Bothnian Bay, with a rate of about 9 mm/year. The coast of the southern Baltic Sea shows subsidence reflecting compensation currents in the upper mantle. 

Slides that occur long after deposition of sediments on the slope are caused by major changes in sedimentary and erosional processes. These changes typically may be caused by eustatic sea-level changes during glacial times, which causes direct deposition of sediments on the upper continental slopes.

In 1923-1985, the Black Sea was characterized by an increase in its water volume, the rate of which attained + 1.5 km3 year 1 [3]. If one converts this value into the sea level change for the same period (with the sea area being 423 x 103 km2), then the rate of the eustatic sea level rise will be 3.5 mm year x. By different assessments, the eustatic (volumetric) increase in the Black Sea level comprises 2.0-4.0 mm year-1 [3,8,24]. 

Although sea level is closely related to continental ice volume, it is also a function of other variables, most notably isostatic effects (see Clark et al. (1978) and review of Peltier (1998) and references therein). Sea-level change can be divided into a eustatic component, which depends... 

For the reconstiTiction of coastline change in the Baltic relative sea-level curves for the last 8000 year can be used (Rosentau et al., 2007). They are derived from data of ancient nearshore sediments. To illustrate the general pattern of sea-level change in the Baltic area, eight typical curves are shown in Fig. 14.4. Each curve mirrors the effects of both eustatic sea-level...

Eustatic sea-level rise, or global changes in the sea level because of changes in the mass of water in oceans, ocean volumes, and temperature changes. 

Accretion balance refers to the net change in sea level relative to marsh surface elevation at a particular site over time. For a coastal wetland to remain at the same elevation over time, accretion must be equal to subsidence plus eustatic sea-level rise.
