Science (New York, N.Y.)
|March 6, 1987
Resumen
Las ondas internas generadas por las corrientes de marea concentraron un derrame de petróleo de asfalto líquido. Estas olas atraparon el 68% del petróleo, aumentando significativamente la abundancia de bolas de alquitrán en las zonas de convergencia.
Área de la Ciencia:
- Oceanografía La oceanografía es la oceanografía.
- Contaminación del mar La contaminación del mar La contaminación del mar La contaminación del mar
Sus antecedentes:
- Los derrames de petróleo representan amenazas ambientales significativas.
- La comprensión de los mecanismos de transporte de contaminantes es crucial para la mitigación.
Objetivo del estudio:
- Investigar el papel de las ondas internas en la concentración y transporte de los componentes del derrame de petróleo.
- Para cuantificar la eficiencia de las ondas internas en la captura de material de derrame de petróleo.
Principales métodos:
- Se recogieron muestras de redes de plancton en diferentes zonas en relación con las ondas internas.
- Las muestras analizadas para la abundancia de bolas de alquitrán (asfalto líquido).
- Concentraciones comparadas de bolas de alquitrán delante, detrás y sobre las zonas de convergencia/divergencia de ondas internas.
Principales resultados:
- Las bolas de alquitrán eran más de 30 veces más abundantes en la zona de convergencia.
- Las ondas internas "atraparon" aproximadamente el 68% del asfalto encontrado.
- Se observó el transporte hacia la costa de bolas de alquitrán desde un tramo de 8 km de océano.
Conclusiones:
- Las ondas internas actúan como un mecanismo significativo para concentrar y transportar los desechos del derrame de petróleo.
- Las zonas de convergencia de las ondas internas son puntos calientes para los contaminantes acumulados.
- Las ondas internas juegan un papel crítico en el destino y el transporte de la contaminación marina por petróleo.

01:26Microbial Bioremediation of Hydrocarbons
Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...
01:04Travelling Waves
A wave is a disturbance that propagates from its source, repeating itself periodically, and is typically associated with simple harmonic motion. Mechanical waves are governed by Newton's laws and require a medium to travel. A medium is a substance in which a mechanical wave propagates, and the medium produces an elastic restoring force when it is deformed.
Water waves, sound waves, and seismic waves are some examples of mechanical waves. For water waves, the wave propagation medium is water;...

01:07Propagation of Waves
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

00:46Bioremediation
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
01:07Reflection of Waves
When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...
01:17Standing Waves
Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...
