Seg\u00fan\u00a0estudio<\/strong>, el\u00a0Oc\u00e9ano Austral<\/strong>\u00a0ha sido identificado como la regi\u00f3n con el\u00a0aire\u00a0<\/strong>m\u00e1s limpio, todo gracias a que no existe actividades humanas, te informamos.<\/p>\n\n\n\n

De acuerdo a un estudio <\/strong>de La Universidad de Colorado para medir la composici\u00f3n de bioaerosol del Oc\u00e9ano<\/strong> Austral al sur de los 40 grados de latitud sur, se identific\u00f3 una regi\u00f3n atmosf\u00e9rica no alterada por las actividades relacionadas con los humanos y por consecuencia, con el aire <\/strong>m\u00e1s limpio del mundo, te proporcionamos la informaci\u00f3n.<\/p>\n\n\n\n

El grupo de la profesora de la Universidad Estatal de Colorado, Sonia Kreydenweiss, con sede en el Departamento de Ciencia Atmosf\u00e9rica, encontr\u00f3 que el aire de la capa l\u00edmite que alimenta las nubes inferiores sobre el Oc\u00e9ano Austral es pr\u00edstino, libre de part\u00edculas, llamadas aerosoles, producidas por actividades antropog\u00e9nicas o transportadas desde tierras distantes. Sus hallazgos se publican <\/a>en Proceedings of the National Academy of Sciences.<\/p>\n\n\n\n

El tiempo y el clima son procesos complejos que conectan cada parte del mundo con cualquier otra regi\u00f3n, y con el cambio clim\u00e1tico r\u00e1pidamente como resultado de la actividad humana, es dif\u00edcil encontrar cualquier \u00e1rea o proceso en la Tierra que no haya sido tocado por las personas.<\/p>\n\n\n\n

Estudio del aire del Oc\u00e9ano<\/h2>\n\n\n\n

Kreidenweis y su equipo sospecharon que el aire sobre el remoto Oc\u00e9ano <\/a>Austral que rodea la Ant\u00e1rtida ser\u00eda el menos afectado por los humanos y el polvo de los continentes. Se dispusieron a descubrir qu\u00e9 hab\u00eda en el aire y de d\u00f3nde ven\u00eda.<\/p>\n\n\n\n

Thomas Hill, coautor del estudio, mencion\u00f3 que pudieron usar las bacterias en el aire sobre el Oc\u00e9ano Austral como una herramienta de diagn\u00f3stico para inferir las propiedades clave de la atm\u00f3sfera inferior. Ejemplo, que los aerosoles que controlan las propiedades de las nubes de SO est\u00e1n fuertemente vinculados a los procesos biol\u00f3gicos oce\u00e1nicos, y que la Ant\u00e1rtida parece estar aislada de la dispersi\u00f3n de microorganismos hacia el sur y la deposici\u00f3n de nutrientes de los continentes del sur.<\/p>\n\n\n\n

Las muestras fueron recolectadas durante la campa\u00f1a de campo S\u00d3CRATES, dirigida por el cient\u00edfico investigador y coautor Paul DeMott. La estudiante de posgrado Kathryn Moore analiz\u00f3 el aire en la capa l\u00edmite marina, la parte inferior de la atm\u00f3sfera que tiene contacto directo con el oc\u00e9ano, a bordo del barco Research Vessel Investigator mientras navegaba hacia el sur desde Tasmania hasta el borde del hielo ant\u00e1rtico. El cient\u00edfico investigador y primer autor Jun Uetake examin\u00f3 la composici\u00f3n de los microbios en el aire capturados desde el barco.<\/p>\n\n\n\n

La composici\u00f3n bacteriana tambi\u00e9n se diferenciaba en amplias zonas latitudinales, lo que sugiere que los aerosoles de masas de tierra distantes y las actividades humanas, como la contaminaci\u00f3n o las emisiones del suelo causadas por el cambio en el uso de la tierra, no viajaban hacia el sur en el aire ant\u00e1rtico.<\/p>\n\n\n\n

Estos resultados contrarrestan todos los dem\u00e1s estudios de oc\u00e9anos en los subtropicales y el hemisferio norte, que encontraron que la mayor\u00eda de los microbios proven\u00edan de continentes a favor del viento.<\/p>\n\n\n\n

El aire sobre el Oc\u00e9ano Austral estaba tan limpio que hab\u00eda muy poco ADN para trabajar. Hill atribuy\u00f3 la calidad de sus resultados al proceso de laboratorio limpio de Uetake y Moore. Jun y Kathryn, en cada etapa, trataron las muestras como art\u00edculos preciosos, teniendo un cuidado excepcional y utilizando la t\u00e9cnica m\u00e1s limpia para evitar la contaminaci\u00f3n del ADN bacteriano en el laboratorio y los reactivos.<\/p>\n","protected":false},"excerpt":{"rendered":"
