A new study combining the latest archaeological evidence with state-of-the-art geoscience technologies provides evidence that climate change was a key ingredient in the collapse of the great Indus or Harappan Civilization almost 4000 years ago. The study, led by WHOI geologist Liviu Giosan, also resolves a long-standing debate over the source and fate of the Sarasvati, the sacred river of Hindu mythology.
Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean’s carbon cycle—the pathway through which carbon enters and is used by the marine ecosystem. It will also offer an important point of reference for determining how those levels of carbon change over time, and how the ecosystem responds to rising global temperatures.
The Woods Hole Oceanographic Institution (WHOI) will host a public forum on the impacts of climate change on water availability worldwide. “Drought or Deluge: The Ocean and Earth's Changing Water Cycle,” will be held on May 17 at 7 p.m. in Redfield Auditorium, featuring experts on extreme weather, changing rainfall patterns, and the impact of changing water supplies on the developing world.
Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study by WHOI scientists shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish.
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. The study has implications for our understanding of the monsoon’s response to climate change.
Global warming could destabilize the pool of carbon in the Ganges-Brahmaputra basin and similar places on Earth, potentially increasing the rate of CO2 release into the atmosphere.
WHOI and the Consortium for Ocean Leadership have awarded a contract to Pro-Oceanus Systems, Inc., of Bridgewater, Nova Scotia, Canada, to provide Partial Pressure of CO2, or p(CO2) , air-sea instrument packages for the Coastal and Global Scale Nodes component of the Ocean Observatories Initiative program.
Woods Hole Oceanographic Institution (WHOI) scientists have discovered that bacterial communication could have a significant impact on the planet’s climate.
New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend, says a research team led by the Woods Hole Oceanographic Institution (WHOI).
The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet’s metabolism, including the cycle of underwater life and the delicate balance of carbon in the ocean and atmosphere. Now, scientists at the Woods Hole Oceanographic Institution (WHOI) have observed ocean crust forming in an entirely unexpected way—one that may influence those cycles of life and carbon and, in turn, affect the much-discussed future of the world’s climate.
Numerous studies are documenting the growing effects of climate change, carbon dioxide, pollution and other human-related phenomena on the world’s oceans. But most of those have studied single, isolated sources of pollution and other influences. Now, a marine geochemist at the Woods Hole Oceanographic Institution (WHOI) has published a report in the latest issue of the journal Science that evaluates the total impact of such factors on the ocean and considers what the future might hold.
Woods Hole Consortium Delegates Participating in U.N. Climate Change Conference in Copenhagen this Week
Directors and scientists from the Woods Hole Consortium are in Copenhagen, Denmark, this week to speak on climate change impacts on ocean, air, land, and polar-ice ecosystems—whose fates are inextricably linked—at the United Nations Climate Change Conference (COP15).
The Intergovernmental Panel on Climate Change estimates that sea level may rise as much as two feet over the next 100 years. However, we lack a full understanding of polar ice cap behavior, and there is concern that the potential for future sea level rise may be significantly underestimated. On Friday, September 25, 2009, from 2 – 5 p.m., in Redfield Auditorium, Water Street, Woods Hole, the Woods Hole Oceanographic Institution (WHOI) is hosting a free public colloquium entitled “Where Land & Sea Meet: Managing Shoreline Change Over the Next 100 Years.”
A new 2,000-year-long reconstruction of sea surface temperatures (SST) from the Indo-Pacific warm pool (IPWP) suggests that temperatures in the region may have been as warm during the Medieval Warm Period as they are today.
A paper published this week in Science shows for the first time that the warming climate is changing the numbers and composition of phytoplankton—the base of the food web—along the western shelf of the Antarctic Peninsula.
Popularized by the 2005 movie “March of the Penguins,” emperor penguins could be headed toward extinction in at least part of their range before the end of the century, according to a paper by Woods Hole Oceanographic Institution (WHOI) researchers published January 26, 2009, in Proceedings of the National Academy of Sciences of the United States of America.
Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that’s exactly what yellow band disease (YBD) is—a bacterial infection that sickens coral colonies. Researchers at the Woods Hole Oceanographic Institution (WHOI) and colleagues have found that YBD seems to be getting worse with global warming and announced that they’ve identified the bacteria responsible for the disease.
Using a 218-year-long temperature record from a Bermuda brain coral, researchers at the Woods Hole Oceanographic Institution (WHOI) have created the first marine-based reconstruction showing the long-term behavior of one of the most important drivers of climate fluctuations in the North Atlantic.
Scientists have offered several competing theories for what led to the extinction of the Neanderthals, with much of the debate focusing on the relative roles of climate change versus conflict with modern humans. New research shows that Neanderthals did not die out at a time of extreme and sudden climatic change, as some researchers have suggested.
The frequency of intense hurricanes in the Atlantic Ocean appears to be closely connected to long-term trends in the El Niño/Southern Oscillation and the African monsoon, according to new research from the Woods Hole Oceanographic Institution (WHOI). Geologists Jeff Donnelly and Jonathan Woodruff made that discovery while assembling the longest-ever record of hurricane strikes in the Atlantic basin.
