Transporte alrededor del mundo de la nube de polvo volcánico de El Chichón
Science (New York, N.Y.)
|July 8, 1983
Resumen
La erupción de El Chichón de 1982 creó una masiva nube de polvo estratosférico que rodeó el globo en solo tres semanas. Esta nube de polvo volcánico fue la más grande y duradera jamás documentada utilizando imágenes satelitales.
Área de la Ciencia:
- Volcanología Volcanología.
- Ciencias de la atmósfera Ciencias atmosféricas.
- La detección remota con sensores.
Sus antecedentes:
- La erupción de El Chichón de 1982 inyectó una cantidad significativa de material volcánico en la estratosfera.
- Comprender la dispersión de la ceniza volcánica es crucial para el clima y la seguridad de la aviación.
Objetivo del estudio:
- Para rastrear el movimiento global y la duración de la nube de polvo estratosférico de la erupción de El Chichón.
- Para documentar la escala y la persistencia de este importante evento volcánico utilizando datos satelitales.
Principales métodos:
- Utilizó imágenes satelitales de la Administración Nacional Oceánica y Atmosférica (NOAA).
- Se generaron mapas diarios para monitorear la distribución geográfica de la nube de polvo volcánico.
- Analizaron datos satelitales para determinar el tamaño y la longevidad de la nube.
Principales resultados:
- La nube de polvo estratosférico completó una circunnavegación completa de la Tierra en tres semanas.
- Se observó que la nube de polvo de El Chichón era la nube volcánica más grande y persistente documentada a través de imágenes satelitales hasta la fecha.
- La cartografía diaria proporcionó un registro completo de los patrones de movimiento y dispersión de la nube.
Conclusiones:
- La teledetección por satélite es una herramienta eficaz para el monitoreo de fenómenos volcánicos a gran escala.
- La rápida dispersión global pone de relieve el significativo impacto atmosférico de las principales erupciones volcánicas.
- El evento de El Chichón sirve como un punto de referencia para el comportamiento de las nubes volcánicas estratosféricas.

00:53Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

02:12Short-distance Transport of Resources
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
01:18Protein Transport to the Inner Chloroplast Membrane
Proteins targeted to the inner chloroplast membrane, or plastid proteins, are transported by two general pathways: the stop-transfer and the re-insertion or post-import pathways. Most plastid proteins carry N-terminal transit sequences and internal import sequences targeting it to the specific chloroplast subcompartment. Proteins targeted by the stop-transfer pathway have internal hydrophobic sequences that inhibit their translocation into the stroma. As a result, these precursors are arrested...
01:26Transport Across the Golgi
While it is unclear how molecules move between adjacent Golgi cisternae, it is apparent that the molecules move from cis- cisterna, the entry face, to the trans- cisterna, the exit face. Experiments initially suggested vesicles that bud from one cisterna and fuse with the next cisterna to transport proteins between the cisternae. This vesicular transport model describes the Golgi apparatus as a relatively static structure with a unique enzyme composition in each cisterna. Molecules are...
