Meeday Gacanka St. Lawrence, waxaa la fahamsan yahay doonaa oo ku saleysan macnaha guud ee dheeraad ah. width ee afka Lawrence St. webiga - in ka badan 150 km. Bay ayaa aag aad u ballaaran oo la dhimay si qoto dheer galay dalka, la xirrira meesha biyo semi-ku lifaaqan a, taas oo, dhab ahaantii, waa la tixgelin karaa badda in yarna.

Sharaxaad kooban oo ku saabsan

Aagga Bay -. 263 kun km ^2, cadadka guud ee biyo ah -. 35 kun km ^3. Qaabka uu leeyahay gacanka St. Lawrence la mid tahay saddexagalka. Waxaa kala ka koonfur-galbeed waqooyi-bari, waayo, 820 km oo ay width - in ka badan 300 km. In Badweynta Atlaantik, Gulf xanbaarsan biyo ay dhex Straits of 3: Canso koonfurta, koonfur iyo waqooyi Cabot of Belle Isle. Mid kasta oo iyaga ka mid ah waa arrin ballaaran, celceliska qiimaha ee this - 400 km. labada jasiiradood oo waaweyn ku yaalaan biyaha Gacanka St. Lawrence: Anticosti iyo Prince Edward Island. Waxa kale oo jira jasiiradaha yar jasiiradda qaybta dhexe ee Gacanka - Magdalen Islands, in qaybta galbeed - jasiiradda Chipeganskie.

Taasi xashiyihii?

Heerka ugu badan ee ku yaala goobahan -. 60-80 m ee qaybta waqooyi ee Gacanka St. Lawrence hoose ayaa dabeecad variable, halkaas oo biyo-gacmeed ayaa la bedelay berkedaha oo qoto dheer. qoto dheer ayaa celcelis ahaan qayb ka this ee kala duwan ee u dhaxeeya 400-500 m qoto dheer ugu badnaan Bay -. chute Lawrence (572 m).

salinity Biyaha iyo heerkulka

Laba hadda ee Gacanka (Gaspé iyo Cabot) sameeyaan wareegga ah duufaan, dhaqaaqin counter-u socoto. Biyaha ee gacanka waxay leedahay saddex heerarka, kuwaas oo kala duwan ee heerkulka iyo salinity. top ugu yeelsiiyeen. At ay tirayn saameyn cimilada.

heer-kulka biyaha halkan u dhaxeysa +2 ° C si +20 ° C. Laga soo bilaabo December si March yaabaa in lakabka dusha sare la daboolay baraf iyo icebergs loo sameeyay. oo dhumucdiisuna waxay daaha of 18 m - xagaaga in 54 m - jiilaalka. Salinity - 32-34 ‰. The biyo marxaladda labaad maraa at qoto dheer ah 50-100 m Heerkulka -. About 0 ° C, salinity wax yar hoos - ilaa 30-32 ‰. Lakabka hoose ee biyaha isagoo heerkul ah oo ku saabsan +5 ° C iyo salinity sare - in ka badan 35 ‰. biyo diiran lakabka hoose siinayaa Labrador, duudduubay bay kicisay yar.

gudbikaraa dhulka ee

St. Lawrence River maydhay on hoose ah channel bay dhexe. Wuxuu u imanayaa inuu ka ah soohdinta bari. Sababo la socodka badan oo biyaha webiga ee gacanka muddo tobannaan sano si weyn waxaad fartaan Wannaagga kaydka biota.

Marka la eego dhulka ee Gacanka St. Lawrence ayaa neodnoobraznoe soo jeedo. Waxa la ogaaday in qaybta waqooyi ee hoose ee Gacanka - gobolka ka mid ah Precambrian Canadian Shield. Iyo xagga koonfureed ee xadka gacanka Appalaachian Mountains wakiil dhagaxyada dhagax, aasaasay in Paleozoic hoose. hoose ee Gulf koonfureed ee St. Lawrence bandhigay granites Devonian iyo korsiiya ay maroorsamaan dhagaxyada Kobenhagen. Sidoo kale, waxaa jira guntan dhagaxyada aasan muddada Carboniferous ah, ee Triassic iyo Permian. macdanta ku aasan hoose ee gacanka halkaas.

berkeddii qoto dheer oo biyaha ku tilmaamaya in ugu hooseysa ayaa sameeyay sarkhaansan Age Ice ah. baraf cadaadis badan sii hoose ee gacanka. Xaqiiqada ah in arrintan la kulmin glaciers ah, waa xaqiiqda ah in biyaha ku Xayiraadda laga yaabaa in sanad kasta laga bilaabo Janaayo ilaa March-April.

cimilada

In cimilada hadda ee jirka biyaha sida Lawrence Bay ee magaalada Lawrence, subarctic, ayaa qof monsoonal ah. heerkulka hawada dhexe ee badatey +15 ° C iyo dhif hoos uga dhaco -10 ° C. Bisha qabow ee sannadka - in February, ugu kulul - August. Sababo la dabiiciga ah ee cimilada monsoon ee xilliga qaboobaha waxaa is qarxiyaan dabaylaha waqooyi-galbeed, keeno qabow, iyo xagaaga - koonfur-galbeed, saturating kulaylka iyo huurka badan.

hawl seismic

nidaamka buurta Appalaachian sidoo kale ka qayb qaatay sifooyinka seismic ee gobolka. muuqaalka guud ee dhulka hoose ee Gulf waa mid aad u kala duwan oo ka kale biyo ku laayeen bari ee North America. 45 km - dhimaya dhumucdiisuna sida uu leeyahay gacanka St. Lawrence.

Location of shay aad u saameeyaa ay waxqabad. The Earth ee qolof ka kooban yahay layers ka kooban hirarka gaadhya muddada Carboniferous ah. dhagaxyada Denser been lakabyada hoose iyo sare waxaa lagu soo bandhigay dhagaxyada carboxylic. Tani waxay soo jeedinaysaa in ee la soo dhaafay gobolka this ahaa seismically firfircoon, laakiin xilligaan la joogo hawshan ayaa yaraaday. Inkastoo, sida laga soo xigtay natiijooyinkii cilmi degaanka ee Jasiiradda Gaspe xilliyo dareemay gaadhya xawaaraha la ruxruxo sare (oo ku saabsan 8.5 km / s).

maraakiibta

Currently, Gacanka St. Lawrence - meel navigation waxaa si firfircoon horumarinta. zone shelf A haboon kalluumaysiga ganacsi. The noocyada ugu badan ee Gacanka: haddock, halibut, baadinimadooda, badda Bass, cunna. Sidoo kale, beeraha saliid horumartay ee la olloga ah.

dunida xayawaanka

Ka sokow tiro badan oo kalluunka ee Europe la Gacanka tegey walruses, nibiriyada badda. Worth alaabta this waa Biraha sii qaalisan, oo sidaas daraaddeed dadka xoolaha ayaa hoos u soo maratay in tobanka sano ee hore ka dib markii dib u dejinta. Haddaba qaadi walruses, nibiriyada badda oo sturgeons ku koobnayn.

Badda World, marka laga reebo kalluunka kala duwan, soo gudbin nuujiya sida weyn. Way badan yihiin: in ka badan 14 noocyada. iyaga ka mid ah waa buluug nibiriyada badda, bowhead iyo cawl shaabadood, Beluga, nibiriyada badda fin. jasiirad yar - meel tiro badan oo ka mid ah shimbiraha wintering. Oo Coast Khaliijka kaynta la deggan by faras duur, madow orso, coyotes, Martens, deerada, Dawacooyinku iyo kuwa kale.

magaca
