El océano Ártico alcanza un punto de no retorno a medida que disminuyen los niveles de nitrato

El océano Ártico cruzó un punto de no retorno alrededor de 2009, según un nuevo estudio que demuestra que la pérdida de hielo marino ha reducido drásticamente los niveles de nitrato en el agua.

Investigadores de la Universidad de Edimburgo analizaron más de 20 años de datos del estrecho de Fram. Descubrieron que el descenso de los niveles de nitrato comenzó a medida que el hielo marino retrocedía rápidamente, lo que expuso las aguas poco profundas a una mayor cantidad de luz solar y aceleró un proceso llamado desnitrificación bentónica, el cual elimina este nutriente del agua de mar.

Study finds hidden channels speed Antarctic ice melt

A new study shows that channels beneath Antarctic ice shelves can trap warm ocean water and accelerate melting from below. Researchers focused on the Fimbulisen Ice Shelf in East Antarctica and found that this process may make even cold regions more vulnerable. The findings suggest current climate models could underestimate future sea level rise.
