A recent study published in Scientific Reports documents the long-term ecological interactions between land and sea ecosystems. Researchers found that replacing native trees with non-native palms led to a cascade of effects, including fewer seabirds, reduced nutrients in waters, and decreased manta ray populations.
Tropical Storm Irina remains stationary off Madagascar's central west coast, with maximum sustained winds of 55 knots and clouds extending over the capital city. The storm is expected to move away from Madagascar on March 2 and make landfall north of Maputo, Mozambique on March 3.
The December 2011 Geology issue presents several studies. Researchers discovered microfossils in the Tayshir Formation, Mongolia, shedding light on ancient life forms. Additionally, a study investigated melt migration mechanisms, finding evidence for porosity waves in the sub-arc mantle of Kohistan Island Arc.
TRMM Satellite tracks Tropical Storm Keila's formation in the Arabian Sea, showing moderate to heavy rainfall spiraling into its center. The storm made landfall in Oman and is expected to track west-southwest along the coastlines of Oman and Yemen.
The remnants of Tropical Depression 8E continue to bring heavy rainfall and strong thunderstorms to Mexico's southwestern coast, with 4-6 inches of rain expected over the states of Guerrero, Michoacan, and Colima. The National Hurricane Center has issued their last warning for the area, indicating a low chance of regeneration.
Tropical Storm Arlene formed over the southwestern Gulf of Mexico, strengthening into a full-fledged hurricane with sustained winds near 40 mph. The GOES-13 satellite captured the storm's development from June 27 to June 28, revealing its transformation from a low-pressure area to a tropical storm.
A new study reveals that concentrated fish farm waste plumes do not consistently dilute immediately in open water. The research found that tides, currents, and the earth's rotation can dramatically affect how far waste plumes travel from their source.
NASA satellite imagery confirms Tropical Storm Phet's intensification, featuring large areas of high cloud tops and strong convection. The storm is forecast to strengthen further and make landfall along the India-Pakistan border by the end of the week.
A new CU-Boulder study reveals the northern Alaska coastline is eroding up to one-third the length of a football field annually. The conditions are caused by a combination of declining sea ice, warming seawater, and increased wave activity, which are leading to the steady retreat of bluffs along the Beaufort Sea.
A new study found that coastal erosion in Alaska more than doubled from historical rates, averaging over 14 meters per year. The authors attribute this increase to declining sea ice extent, rising sea temperatures, and storm power, which may signal a shift in ocean-land interactions.
Coastal erosion in Alaska's Arctic region has more than doubled to 45 feet per year over a 5-year period. The increased erosion rates are attributed to changing arctic conditions, including declining sea ice extent, rising sea level, and increasing storm power.
A new study from Ohio State University suggests that climate change could diminish drinking water resources by up to 50 percent more than previously thought. As sea levels rise, coastal communities may lose fresh water supplies, with vulnerable areas including Southeast Asia, the Middle East, and northern Europe.
Dr Alwyn Ruddock's extraordinary claims about her research on John Cabot's voyages to America have been explored by Dr Evan Jones of the University of Bristol. Ruddock's findings suggest that Cabot explored a large section of the American coastline, claiming it for England in the process.
Analyses of a classic, slow-rupturing tsunami earthquake have provided insight into seismologists and engineers. The data revealed a secondary underwater movement that amplified the original tsunami, creating a wave run-up of over 60 feet along a one-mile section of coastline.
Researchers suggest that productive kelp forests in the Pacific Rim may have facilitated human coastal migrations around 35,000 to 15,000 years ago. This theory is supported by findings of kelp forests near earliest coastal archaeological sites in the Americas.
The study highlights the catastrophic effects of the December 26, 2004 tsunami on Banda Aceh and Lohknga in Indonesia. Water reached 9 meters at the shoreline and over 15 meters inland, with wave-driven sea water inundating areas up to 25 meters above sea level.
A recent South Asian disaster underscores the persistent risk of tsunamis, which can cause devastating damage and loss of life. Experts emphasize the need for broad public education about tsunami dangers and prudent safeguards.
A new model predicts a mega-tsunami could devastate the US coastline, with wave heights reaching 100 meters on the West Saharan shore and 50 kilometers high in Florida. The energy released would be equivalent to the electricity consumption of the entire United States in half a year.
Researchers are using new technology to measure coastal erosion in the UK, with a focus on the North Yorkshire coastline. They are creating highly accurate 3D computer models that detail when and where erosion is most likely to occur.
A Smith College-sponsored expedition will retrace the original route of the Harriman Expedition, assessing ecological and societal changes in Alaska over the last century. The expedition aims to recreate E.H. Harriman's 'floating university' with leading scholars and researchers.
Structural engineers at UCSD are researching ways to stabilize fragile cliffs along the US coastline, particularly in San Diego County. Their comprehensive guidebook aims to provide proactive solutions to prevent erosion and destruction, while maintaining environmental integrity.
Two new studies by researchers at the University of California, Santa Cruz, link El Niño winters to increased coastal erosion and shifting sands along California's central coast. The findings show that damaging coastal storms are three times more likely to occur during an El Niño winter than in other years.
A University of Florida study found that rising sea levels are causing cabbage palms and other coastal trees to die due to saltwater exposure. The phenomenon may be more immediate than thought, with small increases in sea level affecting large areas of flat coastline on the west coast.
A new University of Florida study finds that east coast beaches are increasing in size on average, while west coast beaches remain stable. The study attributes this trend to low wave energy in Florida, which allows sediment to replenish beaches over time.
A University of Florida researcher has found genetic differences in sea oats on the Gulf Coast, which could lead to the development of a "super" sea oat that can stabilize dunes during storms. The goal is to select and propagate sea oats with desirable traits such as quick root growth and extensive rhizome systems.
Researchers have uncovered ancient fragments of sea shells and cutting tools at two sites in Peru, dating the earliest evidence of maritime-based societies in the Americas between 11,000 and 13,000 years ago. The discoveries challenge traditional views on Paleoindian societies and suggest a more diverse set of strategies for survival.
A joint research project is underway to locate and evaluate the condition of sunken whaling vessels lost off Alaska's north coast in 1871. The expedition, led by the West Coast and Polar Regions Undersea Research Center, utilizes side-scan sonar and a remotely operated vehicle (ROV) provided by NASA.
A team of scientists is tracking El Niño changes using a remote cloud observatory in the Western Pacific. Continuous measurements are being collected to evaluate and develop cloud property and radiation algorithms for global climate models.
Researchers used tree-ring analysis to confirm a devastating 1700 earthquake along the Pacific Northwest coast triggered a tsunami that flooded coastal Japan. The study provides new evidence for the Cascadia subduction zone's role in earthquakes of magnitude 9.
Aperlae, a 2,400-year-old Mediterranean port city, was established in the 4th century B.C. to harvest Tyrean purple dye, despite its harsh coastline and lack of fresh water. Archaeological evidence suggests the city's residents used large tanks to manufacture and store the valuable dye.
