These habitats are also critically important for many species harvested in the Nation's commercial fish and shellfish industries. Submerging shorelines might have all of the following characteristics except: Eustatic changes in sea level might include: increased glacial melting due to the global warming. c. the most stable shoreline features. Marie Wegener - DSDS-Gewinnerin 2018 . Changes considered include number of barriers, area and perimeter, shoreline length, barrier sinuosity and width, presence and number of relict terminus features, presence and coverage of tundra vegetation, barrier orientation, termini migration rates, and elevation metrics. Sea stacks are the result of and parallel to the shore. Many serve as habitat and protection for native species and shelter the coast from waves and storms that can flood and erode the adjacent mainland. Coasts are classified into three groups based on tidal range: microtidal, 02 meter tidal range; mesotidal, 24 meter tidal range; and macrotidal, >4 meter tidal range.
