La Niña
La Niña (/lɑːˈniːnjə/, Spanish pronunciation: [la ˈniɲa]) is a coupled ocean-atmosphere phenomenon that is the colder counterpart of El Niño, as part of the broader El Niño–Southern Oscillation (ENSO) climate pattern. The name La Niña originates from Spanish, meaning "the little girl", by analogy to El Niño meaning "the little boy". In the past it was also called an anti-El Niño,[1] and El Viejo (meaning "the old man").[2]
During a La Niña period, the sea surface temperature across the eastern equatorial part of the central Pacific Ocean will be lower than normal by 3 to 5 °C (5.4 to 9 °F). An appearance of La Niña persists for at least five months

Valles Caldera
Valles Caldera (or Jemez Caldera) is a 13.7-mile (22.0 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico.[1] Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape.[3] The highest point in the caldera is Redondo Peak, an 11,253-foot (3,430 m) resurgent lava dome located entirely within the caldera. Also within the caldera are several grass valleys, or valles, the largest of which is Valle Grande (locally /ˈvaɪ.eɪ ˈɡrɑːndeɪ/ VY-ay GRAHN-day), the only one accessible by a paved road. Much of the caldera is within the Valles Caldera National Preserve, a unit of the National Park System [...More Info...]       [...Related Items...] |

Pollen
Pollen is a powdery substance consisting of pollen grains which are male microgametophytes of seed plants, which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of coniferous plants. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics [...More Info...]       [...Related Items...] |

Sierra Nevada (U.S.)
The California Gold Rush began at Sutter's Mill, near Coloma, in the western foothills of the Sierra.[49] On January 24, 1848, James W. Marshall, a foreman working for Sacramento pioneer Spanish missions, pueblos (towns), presidios (forts), and ranchos along the coast of California, no Spanish explorers visited the Sierra Nevada.[45] The first Americans to visit the mountains were amongst a group led by fur trapper Jedediah Smith, crossing north of the Yosemite area in May 1827, at Ebbetts Pass.[45]
In 1833, a subgroup of the Bonneville Expedition led by Joseph Reddeford Walker was sent westward to find an overland route to California

YYYYJJJJJVVVVMPPPPA
YYYY
is the four-digit year of the reference and JJJJJ
is a code indicating where the reference was published. In the case of a journal reference, VVVV
is the volume number, M
indicates the section of the journal where the reference was published (e.g., L
for a letters section), PPPP
gives the starting page number, and A
is the first letter of the last name of the first author
A digital object identifier (DOI) is a persistent identifier or handle used to identify objects uniquely, standardized by the International Organization for Standardization (ISO).[1] An implementation of the Handle System,[2][3] DOIs are in wide use mainly to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. However, they also have been used to identify other types of information resources, such as commercial videos.
A DOI aims to be "resolvable", usually to some form of access to the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL, indicating where the object can be found. Thus, by being actionable and interoperable, a DOI differs from identifiers such as ISBNs and ISRCs which aim only to identify their referents uniquely
