"Long-lost Continent Found: Scientists' 375-Year Discovery"

After 375 years, scientists have officially discovered the missing continent of Zealandia, which was once part of an ancient supercontinent. Initially theorized in Roman times and partially discovered in the 1600s, the continent is mostly underwater and roughly 1.89 million square miles in size. Zealandia, also known as Te Riu-a-Māui in the Māori dialect, had been hiding in plain sight and was part of the ancient supercontinent of Gondwana over 500 million years ago. Geologists from GNS Science made the discovery in 2017, shedding light on the continent's separation from the supercontinent and its submersion beneath the waves.

"Uncovering a Magnetic Anomaly Beneath New Zealand's Lake Rotorua"

Detailed maps of Lake Rotorua in New Zealand have uncovered hidden subsurface features, including hydrothermal explosion craters, traces of an old river, and a significant magnetic anomaly in the lake's southern section. GNS Science researchers used various measurement techniques to probe beneath the lake's surface, revealing the presence of hydrothermal activity and pinpointing active regions.

"Uncovering a Magnetic Anomaly Beneath Lake Rotorua in New Zealand"

New maps have revealed a hidden hydrothermal system beneath New Zealand's Lake Rotorua, located in the crater of a dormant volcano. The maps, created by researchers at GNS Science, show eruption craters, an ancient river, and a large magnetic anomaly in the lake's southern part, indicating that the mainland hydrothermal systems extend into the lake's depths. The anomaly is likely due to hydrothermal fluids transforming highly magnetic minerals into fool's gold, severely diminishing the magnetic signal. Despite this activity, water temperatures near the lake's bottom remain cool due to the large size of the lake.
