| Summary: | ABSTRACT. Monthly mean ice cover distributions for Hudson Bay have been derived, based upon an analysis of nine years of aerial reconnaissance and other data. Information is presented in map form, along with diseussian Of significant features. Ice break-up is seen to work southward from the western, northern, and eastern edges of the Bay; the pattern seems to be a result of local topography, cur-rents, and persistent winds. Final melting occurs in August. Freeze-up commences in October, along the northwestern shore, and proceeds southeastward. The entire Bay is ice-covered by early January, except for persistent shore leads. RÉSUMÉ. Conditions de la glace dans la mer d’Hudson. A partir de l’analyse de neuf années de reconnaissances aériennes et d’autres données, on a pu déduire des moyennes mensuelles de distribution de la glace pour la mer d’Hudson. L‘informa-tion est présentte sous formes de cartes et de discussion des Cléments significatifs. On y voit que la débâcle progresse vers le sud à partir des marges ouest, nord et est de la mer; cette séquence semble être le résultat de la topographie locale, des courants et.des vents dominants. La fonte se termine en aofit. L’enge€wommence en octobre le long de la rive nord-ouest et progresse vers le sud-est. Sauf pow les chenaux côtiers persistants, la mer est entihrement gelée au début de janvier. |
