During the early Paleozoic, southern and western New Mexico were submerged by a warm shallow sea that would come to be home to creatures including brachiopods, bryozoans, cartilaginous fishes, corals, graptolites, nautiloids, placoderms, and trilobites. During the Ordovician the state was home to algal reefs up to 300 feet high.
Bandera Volcano Ice Cave, also known as Zuni Ice Cave, is a lava tube cave in New Mexico with an internal temperature significantly less than above-ground summertime ambient temperature; it contains perennial ice. [1] The inside temperatures can fluctuate between −1 and 10 °C (31 and 50 °F). Some areas of the ice cave never reach above ...
The ancient sea, which existed from the early Late Cretaceous (100 Ma) to the earliest Paleocene (66 Ma), connected the Gulf of Mexico to the Arctic Ocean. The two land masses it created were Laramidia to the west and Appalachia to the east. At its largest extent, it was 2,500 feet (760 m) deep, 600 miles (970 km) wide and over 2,000 miles ...
USS Skate (SSN-578) was the third submarine of the United States Navy named for the skate, a type of ray, was the lead ship of the Skate class of nuclear submarines.She was the third nuclear submarine commissioned, the first to make a completely submerged trans-Atlantic crossing, the second submarine to reach the North Pole, and the first to surface there.
The report said Antarctic sea ice was relatively stable during the period when the data was recorded, but over the past five years had reached record lows, with BAS saying there were more than ...
The research from the National Oceanic and Atmospheric Administration found warmer, ice-free conditions in the southeast Bering Sea — the kind of conditions found in sub-Arctic regions — are ...
To estimate ice area, scientists calculate the percentage of sea ice in each pixel, multiply by the pixel area, and total the amounts. Scientists set a threshold percentage to estimate ice extent, and count every pixel meeting or exceeding that threshold as "ice-covered." The common threshold is 15 %.
The geologic history of the state began with its assembly during the Yavapai and Mazatzal orogenies 1750 to 1650 million years ago (Mya). This was followed by 200 million years of tectonic quiescence that ended in the Picuris orogeny. This event transformed the New Mexico crust into mature continental crust.
