Chesapeake Bay

The mean range of tide in the Chesapeake Bay reaches about 2 .8 feet at the Atlantic Ocean entrance . There is a unique characteristic that this Chesapeake Bay had . There is a widely varying elevation of the high tide and low tide that gave the Chesapeake Bay its unique characteristic . The high tide is also not constant . There is a time that the high water on this Bay that reaches near Havre de Grace , while the following high tide would be just around the entrance of

the Bay near the Chesapeake Bay Bridge Tunnel . That characteristic , of completing a wavelength of the dominant semidiurnal tide , is what its `uniqueness ' shows

There is also a characteristic of this Bay that made it interesting to study . Not only on the places nearby the Chesapeake Bay tides varies but even on the Eastern Shore and the Western Shore of the Bay . It is noticeable that there is a higher water level on the Eastern Shore compared to the Western Shore ADDIN EN .CITE SwimGreat Chesapeake Bay SwimNOAA TO HELP PLAN SAFE CHESAPEAKE BAY SWIM2007April 102007http /www .bayswim .com /weather .html (Swim , 2007

Tidal cycles in Chesapeake Bay are classified into two the semidiurnal in which there are two high and low tide each day and the other one classified as mixed tidal cycle , wherein a combination of semidiurnal and diurnal (one high tide and one low tide each day ) tidal cycle occurs ADDIN EN .CITE SwimGreat Chesapeake Bay SwimNOAA TO HELP PLAN SAFE CHESAPEAKE BAY SWIM2007April 102007http /www .bayswim .com /weather .html (Swim , 2007 . The mixed tidal cycle happens in the northern Bay

Tidal changes are evident on the Chesapeake Bay . Due to its shallow coast , and its weak tide and tidal current , the tides in the Bay can easily change . There are factors which causes these tidal changes to happen . Wind direction in relation to the orientation of the basin causes tide change for a short duration while a long duration effects on the tide might be brought by a large scale East coast storm

The tidal regimes and changes in tidal cycle in the Chesapeake Bay are important for the species (e .g . crabs ) living near it . Many different populations of species near the shore spawn during this time . Some chooses the low tide , while several species prefer when the tide is high . Tidal dominance , during full moon , where the pull of the moon on the earth 's gravity is strong , causing a high tide , is the time when the spawning is also high . Though there is evidence that spawning occurs during new moon , when the tide is low , it is apparent that more of the spawning happens during full moon

Tidal Power Plant in North America

There is one tidal power plant that exists in the North America . It was the Annapolis Royal pilot tidal power plant and is situated in Annapolis Royal , Canada . To further build a tidal power plant as a source of energy...
