Economical Solutions For Maintaining Critical Delta Environments

Woods Hole Oceanographic Institution Millions of people across the world live or depend on deltas for their livelihoods. Formed at the lowest part of a river where its water flow slows and spreads into the sea, deltas are sediment-rich, biodiverse areas, a valuable source of seafood, fertile ground for agriculture, and host to ports important for transportation. At least half of the deltas around the world are so-called “wave dominated deltas” – open to the sea and under the...

Impact From Humans Felt On Black Sea Long Before Industrial Era

When WHOI geologist Liviu Giosan first reconstructed the history of how the Danube River built its delta, he was presented with a puzzle. In the delta´s early stages of development, the river deposited its sediment within a protected bay. As the delta expanded onto the Black Sea shelf in the late Holocene and was exposed to greater waves and currents, rather than seeing the decline in sediment storage that he expected, Giosan found the opposite. The delta continued to grow. In fact,...

Climate Change Responsible For Indus Decline

Brett Smith for RedOrbit.com New research has shed a light on an ancient Asian civilization and given a glimpse into what the future might hold for the region. Climate change is now thought to be responsible for the decline of the Indus civilization, an empire that stretched over more than a million square kilometers. One of the first great urban cultures that also included Egypt and Mesopotamia, its people lived primarily along rivers from the Arabian Sea to the Ganges, over what is...

Past Monsoon Changes Linked To Major Shifts In Indian Civilizations
2012-03-19 04:05:57

A fundamental shift in the Indian monsoon has occurred over the last few millennia, from a steady humid monsoon that favored lush vegetation to extended periods of drought, reports a new study led by researchers at the Woods Hole Oceanographic Institution (WHOI). The study has implications for our understanding of the monsoon´s response to climate change. The Indian peninsula sustains over a billion people, yet it lies at the same latitude as the Sahara Desert. Without a monsoon, most...

Did a catastrophic flood of biblical proportions drown the shores of the Black Sea 9,500 years ago, wiping out early Neolithic settlements around its perimeter? A geologist with the Woods Hole Oceanographic Institution (WHOI) and two Romanian colleagues report in the January issue of Quaternary Science Reviews that, if the flood occurred at all, it was much smaller than previously proposed by other researchers. Using sediment cores from the delta of the Danube River, which empties into the...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
