US: A Stroll on a Gulf Beach Yields a Dolphin Disposal

Image

Laurel Lockamy has seen her share of dead sea life washing up on the beaches of Mississippi. Like a few other residents, she's toted her camera along wherever she goes, documenting the dolphins, sea turtles, red fish and plethora of dead birds that seem to be washing in unusually high numbers.

That isn't stopping Gulf businesses from hoping for a better year than last, when beaches were soaked in oil and tourism vanished with the black tide. Now there are signs business is rebounding. Tourist industries in Florida panhandle report better than expected traffic this year. Some in Congress in fact are pushing for increased drilling in the Gulf, with fewer safety and environmental reviews of the process. It seems some lawmakers have short memories.

But not all is well in the Gulf. High numbers of endangered sea turtles and dolphins have washed into the beaches, although the number of fatalities is declining. Scientists still don't know what has caused this spike in deaths.


Comment: The scientists may claim they don't know what's caused the spike in deaths, but we think it's pretty obvious to everyone else. The BP oil spill is the greatest environmental disaster of its kind in our history. BP dumped two million gallons of toxic oil dispersants in the Gulf, and marine life continues to perish.


Comment: They will never say for sure because they are either paid by BP, or silenced by government agencies.

US: Colorado - Latest storm to bring even more rain, mountain snow

A strong Pacific storm system will bring rain and snow to the mountains and showers to the Front Range Wednesday, the National Weather Service said tonight.

In the high country, winter-like weather and flood advisories could linger through Saturday, and a winter weather advisory is in effect for parts of southern Colorado above 10,000 feet until 6 a.m. Friday. Those areas could see an additional 10 inches of snow atop and already record snowpack.

Areas above 9,000 feet elevation could see 3 to 6 inches of new snow Wednesday, forecasters said.

The Denver metro area has a 60 percent chance of rain and thunderstorms Wednesday afternoon and an 80 percent chance of showers in the evening, forecasters said.

It's another wet morning Wednesday in Southern California, which has set new records for rain and cold in recent days.

The National Weather Service predicts a 40% chance of showers Wednesday morning, giving way to cloudy skies.

Daily records for temperature and rainfall totals were tied and broken Tuesday as a storm system hit Southern California.

The low temperature at UCLA was 49 degrees, tying a record set in 1962, according the National Weather Service.

A record-rainfall total for the day was set at Los Angeles International Airport. Tuesday's 0.23 inches of rain at LAX eclipsed a record of 0.12 inches that had stood since 1949, the Weather Service said.

Infrared emissions above the epicenter increased dramatically in the days before the devastating earthquake in Japan, say scientists.

Geologists have long puzzled over anecdotal reports of strange atmospheric phenomena in the days before big earthquakes. But good data to back up these stories has been hard to come by.

In recent years, however, various teams have set up atmospheric monitoring stations in earthquake zones and a number of satellites are capable of sending back data about the state of the upper atmosphere and the ionosphere during an earthquake.

Efforts to remove climate-warming carbon dioxide from Earth's atmosphere appear to be getting a helping hand from a surprising source: the iron in meltwater from Antarctic icebergs.

Icebergs calving off of Antarctica are shedding substantial iron - the equivalent of a growth-boosting vitamin - into waters starved of the mineral, a new set of studies demonstrates. This iron is fertilizing the growth of microscopic plants and algae, transforming the waters adjacent to ice floes into teeming communities of everything from tiny shrimplike krill to fish, birds and sometimes mammals.

Clipping wings when volcanoes erupt

Air transport officials launched a no-fly zone when Iceland's Eyjafjallajökull volcano reared its ugly head last year. But was the move justified? Flying through an ash cloud would have been a dangerous maneuver, if not deadly. This is where a team of researchers comes in.

Scientists from the University of Copenhagen in Denmark and the University of Iceland have created a protocol to give traffic authorities the help they need to quickly determine if planes should be grounded when ash threatens airspace safety. The results of the study are presented in the journal Proceedings of the National Academy of Science (PNAS).

Researchers say volcanic ash could put planes, and the lives of passengers, in grave danger, particularly if particles are small enough to travel high and far. These particles could sandblast the bodies and windows of airplanes, and they could even melt inside jet engines.

Red flags went up when ash from the Eyjafjallajökull eruption materialized. The researchers say officials were right to ground all airplanes in April 2010. For her part, Professor Susan Stipp from the Nano-Science Center of the University of Copenhagen says the team's latest method to quickly evaluate future ash is a key development.

US: Heavy rainfall may be linked to sharks' deaths

This winter's heavy rains - beneficial to so many species - may, in fact, be diluting saltwater in San Francisco Bay so dramatically that leopard sharks are dying in the very spots where they prefer to give birth and search for food, scientists said Tuesday.

State biologists investigating a rash of leopard shark casualties around the region over the past month think the torrents of freshwater flowing into shoreline lagoons may be throwing the body chemistry of the fish fatally off balance.

Colombia's capital Bogota has been cut off from a large part of the northeast of the country after a landslide destroyed a bridge connecting the capital with the city of Bucaramanga Tuesday evening.

According to media reports, the landslide took place 15 miles south of Bucaramanga and has disconnected Bogota to Bucaramanga, Cucuta and forces travelers to the Caribbean city of Barranquilla to take a large detour.

The landslide reportedly did not only destroy the bridge, but also a police post and swept away a motorbike and a car. Media reports are contradictory about injuries. According to newspaper El Espectador no injures were reported, while Caracol Radio reported 15 people were injured.

Eruption at Nicaraguan Volcano

Telica Volcano
© Lee Siebert (Smithsonian Institution)Telica volcano, seen here from the León-Chinandega highway, is one of a group of interlocking cones and vents along a NW trend. The summit of Telica, which is one of Nicaragua's most active volcanoes, is unvegetated, and deep erosional gulleys have been dissected into the lower flanks of the cone. Frequent historical eruptions have been recorded at Telica since the 16th century.
Managua - Nicaragua's Telica volcano spewed a massive cloud of gas and ash into the air Tuesday following several strong explosions.

Material was ejected 1.2 kilometres into the air above the crater of the 1,060-metre volcano, the seismological institute Ineter said. A total of 50 explosions were recorded.

Since May 9, Ineter has recorded 59 seismic shocks in the area, and Telica had ejected a large amount of sand on nearby cities since Friday.

Sixty nearby villages were evacuated as a precautionary measure.

The volcano is located in Leon province, some 130 kilometres north-west of Managua. It last erupted in 1948.

Clues studied to predict when peak will erupt again

© Columbian filesMount St. Helens shook itself awake in October 2004 after eight years of relative quiet. Eruptions and dome-building continued until January of 2008, when the volcano entered a new period of hibernation. Scientists are now reading signals from deep within the mountain and rocks dating back thousands of years to try to predict when the mountain will recharge and become active again. This view from 2005 looks east, showing lobes of new domes formed within the crater during its 2004-08 eruptive stage.

Mount St. Helens has been mostly quiet since its most recent dome-building eruptions ended in January 2008. But scientists say it's a sure thing the volatile volcano in our backyard will reawaken.

The question they hope to answer is when.

Clues to the volcano's future lie in the faint signals of magma moving in a cigar-shaped chamber deep within the mountain, in the eruptive history of a similar volcano on Russia's remote Kamchatka Peninsula, and in the long geological record contained within Mount St. Helens itself.

Cynthia Gardner, a scientist at the U.S. Geological Survey's Cascades Volcano Observatory in Vancouver, predicts the mountain will resume rebuilding itself sooner rather than later.

"Mount St. Helens will probably erupt again within the next several decades," she says. "As we look at its eruptive history, we know there was a flank collapse 2,500 years ago. We saw the cone rebuild itself over a century or a century and a half."

Yet since the 1980 eruption, she said, the mountain has rebuilt only 7 percent of its pre-eruption mass. "If we look at patterns from St. Helens' past history, and from volcanoes around the world, we come to the conclusion we are likely to see more eruptions."
