Branchinecta paludosa are then reproductive for 35–45 days. Branchinecta paludosa Branchinecta paludosa is a species of fairy shrimp with a Holarctic distribution. "B. paludosa" is widely distributed in the Arctic tundra of Eurasia, chiefly above latitudes of 60° north. It reaches its northern limit, 77° north at Ivanov Bay in the Novaya Zemlya archipelago. Further populations exist as far south as the Tatra Mountains on the Polish–Slovakian border at about 49° north. There are scattered records from North America, mostly near the Arctic Ocean. After hatching, young "B. paludosa" spend 20–30 days as larvae, before reaching sexual maturity between the end of
Novaya Zemlya Novaya Zemlya. The launch rocket was subsequently deployed to Cuba. 1963 saw the implementation of the Limited Test Ban Treaty which banned most atmospheric nuclear tests. The largest underground test in Novaya Zemlya took place on September 12, 1973, involving four nuclear devices of 4.2 megatons total yield. Although far smaller in blast power than the Tsar Bomba and other atmospheric tests, the confinement of the blasts underground led to pressures rivaling natural earthquakes. In the case of the September 12, 1973, test, a seismic magnitude of 6.97 on the Richter Scale was reached, setting off an 80 million ton
