The current understanding of the resolution of these peats to record sea-level variations through time are typified by the works of McCaVrey and Thomson (1980) and Clark and Patterson (1984). McCaVrey and Thomson (1980) suggested that rates of accretion Accelerated sea level rise is 3 - 4 times greater in New England than the global average, and here we describe plant and accretion measures over a 20 year period at CT marshes. Results will help better understand tidal marsh responses to accelerated sea level rise. Sea-level rise is a major indicator of ongoing global change. Sea level has been rising at rates of up to 0.06 m per decade in the twentieth century. Since the 1950s, every subsequent decade has experienced increased rates of sea-level rise. Model experiments show that twentieth century sea-level rise cannot be explained by natural processes alone. This variability in sea level rise accounts for some of the discrepancy in vertical accretion rates in marshes. We reviewed 15 areas dated with Lead-210 or Cesium-137, however, and at least four are clearly not keeping pace with sea level rise. An accretionary balance can be attained if: (1) the long-term filling rate exactly equals the relative sea-level rise, a situation that leads to constant water depth with time (but not necessarily shallow depths), or (2) the lagoon fills rapidly to capacity (i.e., catches up to the rate of RSL rise) and the accretion surface remains at base level for a long time. Since at least the start of the 20th century, the average global sea level has been rising. Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in). More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per century. These rates were found to be matching or exceeding average sea-level rise reported for Key West, Florida. Organic carbon burial rates were 260 and 393 g m −2 yr 1 within the storm deposit compared to 151 and 168 g m−2 yr−1 overall burial rates.

Predictions represent the potential distribution of each wetland type (see legend) based on their elevation and how frequently they may be inundated under each scenario. If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimeters) by 2100 — enough to cause significant problems for coastal cities, according to the new assessment by Nerem and colleagues from NASA's Goddard Space Flight Center in Greenbelt,

The rate of sea-level rise (SLR) has accelerated since 1990, approximately doubling, with the greatest portion of rise occurring in the southern hemisphere7. However, sea level not only did not rise everywhere, it actually declined in some broad areas. Thus, the pattern of sea level change is complex8.

Vertical accretion allows salt marshes to move up vertically as sea-level rises. This process relies on the contribution of belowground organic matter and sediment  19 Feb 2019 The change in sea levels is linked to three primary factors, all induced by ongoing global climate change: Thermal expansion: When water heats  These rates are flat values applied across the landscape and can be used to highlight how accretion can offset sea level rise.
