Tabula geographica Maris Beaufort.

Mare Beaufort[1] est marginale Oceani Arctici mare,[2] ad septentriones Territoriorum Septentrio-Occidentalium Yukonque Canadae atque Alascae versus, et ad occidentam insularum arcticarum Canadae versus situm. Quod mare ex Francisco Beaufort equite, hydrographo Hibernico, appellatur. Flumen Mackenzie, longissimum in Canada, in Canadiensem Maris Beaufort regionem defluit ad occidentem Tuktoyaktuk versus, unius ex paucis coloniarum continuarum secundum maris litora.

Area superficialis 476 000 chiliometrorum quadratorum, altitudo media 124 et maxima 4683 metra, volumen 22 000 chiliometrorum cubicorum est.[3][4][5]

Superficies maris, cui clima asperrimum est, in glacie concreta plurimis anni mensibus consistit. Transitus navalis usque ad 100 chiliometra latus prope litora olim Augusto Septembrique aperiebatur, sed nuper propter calefactionem globalem in regione Arctica, magnitudo corporis aquae glacie summa aestate carens magnopere augetur. Ante annos recentes, Mare Beaufort fonte glaciei maritimae arcticae magni momenti innotebat.[6] Glacies maritima in Gyro Beaufort, primo Maris Beaufort flumine oceanico, nonnullos annos volvebatur, in crassas glaciei conglutinationes commutans.[7][8]

Flora et fauna[recensere | fontem recensere]

Litus Maris Beaufort, tundra tectum, est septentrionales Ursi maritimi fines in America Septentrionali. Flumen Mackenzie, habitatio naturalis cetaceorum aviumque maritimarum magni momenti, commercium iam vix sustinet.[9] Delta Fluminis Mackenzie permultos lacus et stagna continet, quae Ondatrae zibethici habitant.[10]

In mari vigent 80 fere species zooplanctonis, plus quam 70 species phytoplanctonis,[11] et paene 700 species polychaetorum, bryozoorum, crustaceorum, et molluscorum, sed totum eorum corporum volumen climatis frigidi causa parvum est.[5][12] Inter maiores piscium species sunt Boreogadus saida, Arctogadus glacialis, Eleginus gracilis, Salvelinus alpinus, Oncorhynchus keta, Coregonus autumnalis, Coregonus sardinella, Coregonus clupeaformis, Coregonus nasus, Clupea pallasii, Myoxocephalus quadricornis, Stenodus leucichthys, variique pisces ordinis Pleuronectiformium,.[13]

Orientalis maris pars est maior Delphinapterorum leucas habitatio, quae cetacea 39 000 numerari aestimantur. Qui grex est stabilis et fortasse etiam crescit. Delphinapteri in regione litorali et delta Fluminis Mackenzie aestivant, ubi glacies caret, ac hieme procul ad polynyas maris profundi migrant.
