More than 4,000 years ago, the Harappa culture thrived in the Indus River Valley of what is now modern Pakistan and northwestern India, where they built sophisticated cities, invented sewage systems that predated ancient Rome’s, and engaged in long-distance trade with settlements in Mesopotamia. Yet by 1800 BCE, this advanced culture had abandoned their cities, moving instead to smaller villages in the Himalayan foothills. A new study from the Woods Hole Oceanographic Institution (WHOI) found evidence that climate change likely drove the Harappans to resettle far away from the floodplains of the Indus.Read More
Sea levels in coastal areas can be affected by a number of factors: tides, winds, waves, and even barometric pressure all play a role in the ebb and flow of the ocean. For the first time, however, a new study led by the Woods Hole Oceanographic Institution (WHOI) has shown that river outflow could play a role in sea level change as well.Read More
The Ayeyawady River delta in Myanmar is home to millions of people, and is a hub of agricultural activity. Unlike other large rivers across the world, however, the Ayeyawady has been relatively untouched by large infrastructure and dam projects for the past 50 years, and its geologic evolution has never previously been studied.Read More
Scientists have long known that steep mountain ranges can draw carbon dioxide (CO2) out of the atmosphere as erosion exposes new rock, it also starts a chemical reaction between minerals on hill slopes and CO2 in the air, weathering the rock and using CO2 to produce carbonate minerals like calcite.Read More
Over the last century, many of the world’s major rivers have been modified for the purposes of flood control, power generation, and commercial navigation. A new study out of Woods Hole Oceanographic Institution suggests that engineering modifications to the Mississippi River interact with the have increased the risk of extreme floods to unprecedented levels.Read More
Each summer, the South Asian monsoon transforms parts of India from semi-arid into lush green lands able to support farming. The annual infusion of rainfall and resulting runoff into the Ganges, Brahmaputra, and other rivers in the region also has a very different, but no less dramatic, impact on the Bay of Bengal in the northeast Indian Ocean.Read More
Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the removal and long-term storage of carbon, including the world’s river systems, which transport decaying organic material and eroded rock from land to the ocean.
While river transport of carbon to the ocean is not on a scale that will bail humans out of our CO2 problem, we don’t actually know how much carbon the world’s rivers routinely flush into the ocean – an important piece of the global carbon cycle.
But in a study published May 14 in the journal Nature, scientists from Woods Hole Oceanographic Institution (WHOI) calculated the first direct estimate of how much and in what form organic carbon is exported to the ocean by rivers. The estimate will help modelers predict how the carbon export from global rivers may shift as Earth’s climate changes.Read More
