Rannsókn á áhrifum gosösku á hafið / Volcanic ash team back at sea to gather more data

Alþjóðleg rannsókn á áhrifum gosöskunnar á lífríkið í hafinu er hafin.
Þessi frétt hér að neðan kemur frá BBC, Mbl.is var síðan með smá frétt, væntanlega unna úr þessari. Þekki ekki og virðist ekki koma fram í fréttinni hvort Íslendingar með í þessari rannsókn, mögulega, eða með aðra sjálfir ?

A team of scientists has returned to the North Atlantic to get more data on how the Icelandic volcanic eruption has affected the region's marine biology.

By Mark Kinver, Science and environment reporter, BBC News

They are assessing whether iron within the vast volcanic ash cloud entered the ocean, causing an extended bloom of tiny organisms known as phytoplankton.

The team, in the middle of a five-week cruise, have recorded "enhanced levels" of iron in samples they have collected.

The latest project follows an earlier cruise, carried out in the spring.

The international team of researchers are hoping to measure if trace elements from the ash have had an impact on the region's phytoplankton blooms.

"A hundred million cubic metres of ash was produced by the volcano - that must have gone somewhere and a large part has fallen into the ocean - so that is a significant iron source," said lead scientist Eric Achterberg, from the UK's National Oceanography Centre.

Professor Achterberg explained that the team had limited time to analyse data collected on their first cruise before they headed out to sea again.

"The guys only had six or seven weeks to pack and remobilise for the next cruise," he told BBC News.

However, he added that they did manage to glean some initial information: "For example, when they were right underneath the volcanic ash cloud in Iceland, they found that the iron levels were very high.

"But we have not got a really large-scale picture yet - there is so much data."

The area of the North Atlantic in which the researchers are collecting samples normally has very low inputs of iron and other nutrients from the atmosphere.

It was therefore assumed that phytoplankton were growing in a sub-optimum manner.

"The original objective for this cruise was to go out... and look at the conditions in the ocean after the massive spring bloom," explained Professor Achterberg.

"The hypothesis was that the system would have run out of iron by this point."

However, he added that the eruption in March could potentially change this.

"What we are doing is taking samples from the ocean, the atmosphere, and we are looking at biological growth in the ocean.

"We are seeing some enhanced levels (of dissolved iron) below the "mixed layers" of 20-40 metres deep.

"It may be a result of the volcanic ash, but we really need to have a better look at this on a wider scale."

'Unique opportunity'

If the ash from the eruption added a significant amount of iron to the ocean, the team hope to collect data to confirm that it did trigger extended phytoplankton blooms.

"It is something that we are hoping to see," said Professor Achterberg.

"This would also mean that the phytoplankton would take up more atmospheric CO2 than what it usually does in a normal year."

The expedition - aboard the RRS Discovery, a Natural Environment Research Council (Nerc) vessel - is part of a climate change project that is looking at the efficiency of phytoplankton to absorb atmospheric CO2 and sequester it in the deep ocean.

He went on to say that the cruise, which was originally planned five years ago, provided a "totally unique opportunity".

"Never, at this scale, have people been able to do this.

"Firstly, we do not get that many volcanic eruptions on this scale, and secondly, it is only recently that we have been able to take the iron sampling and carry out analysis in the manner that we can do now.

"It has luckily come together in a very nice manner."

Professor Achterberg said that the team hoped to make the results available "within months" of returning from the current cruise, which is scheduled to end in mid-August.

Almennilegt – sektað vegn rykmyndunar við byggingarframkvæmdir / Good – builder fined for violating dust control measures > $100k

Frétt sem segir frá verktaka í Arizona sem var sektaður um yfir 100 þúsund dollara vegna þess að hann gætti ekki að sér varðandi rykmengun við framkvæmdirnar !

Meðal þess sem verktakar eiga að sinna, en þessi gerði ekki, er:

• setja upp hreinsitæki fyrir farartæki/vinnuvélar;
• hreinsa strax öll óhreinindi sem berast meira en 50 fet frá vinnusvæðinu;
• hafa vatnsúðara í gangi þegar jarðefni er flutt;

Hvernig væri að koma svona reglum í gagnið hérlendis !

Arizona Builder Fined More than $100K for Violating Dust Control Measures

EPA has fined Summit Builders Construction Co., based in Maricopa County, Arizona, $105,610 for allegedly failing to comply with Clean Air Act regulations. In addition to the monetary fine, Summit also is required to take steps to minimize the generation of dust at its construction sites.

“Air pollution from particulate matter directly impacts the health of the community. It’s an especially serious issue in Maricopa County, where air quality does not meet the federal standard,” said Jared Blumenfeld, EPA’s regional administrator for the Pacific Southwest region. “EPA will not tolerate companies who fail to comply with dust control regulations. We are working closely with local air quality agencies to enforce rules to protect the community from airborne dust.”

U.S. Attorney Dennis K. Burke for the District of Arizona added, "Air quality is a concern for many who live in and travel through Maricopa County. The resolution of this case provides for positive measures which will help improve air quality in the future."

In 2006 and 2007, the Maricopa County Air Quality Department (MCAD) inspected five commercial construction projects in Maricopa County and uncovered eight violations for failing to perform various measures required to reduce particulate matter emissions. These included failure to install a trackout control device to remove particulate matter from vehicles; failure to immediately clean up dirt that is tracked more than 50 feet beyond the site; failure to operate a water application system during earthmoving operations; and failure to comply with the dust control plan.

In addition to the penalty, Summit is required to train employees in basic dust control, document that training, and employ qualified dust controls at larger work sites for two years.

Maricopa County exceeds the national health standard for particulate matter, PM-10 (one-seventh the width of a human hair), and has been classified by the EPA as a serious non-attainment area. In May 2010, EPA denied Arizona’s claim that dust storms caused the high pollution readings in Phoenix. Because of this, Arizona must submit an adequate plan to EPA on how the state plans to come into attainment for PM-10. Failure to do so will result in a freeze to the state’s federal transportation funds.

EPA notes that particulate matter affects the respiratory system. Particle pollution is a complex mixture of extremely small particles and liquid droplets in the air. When breathed in, these particles can reach the deepest regions of the lungs, and is linked to a variety of significant health problems, ranging from aggravated asthma to premature death in people with heart and lung disease. The elderly, children, and people with chronic lung disease, influenza, or asthma are especially sensitive to high levels of particulate matter, the agency said.

Snæfellsjökull að hverfa ? / Snæfellsjökull dissapearing ?

Í nýlegu viðtali á RÚV (http://www.ruv.is/frett/snaefellsjokull-ad-hverfa) talaði Helgi Björnsson um hversu hratt Snæfellsjökull hefur minnkað og hvernig árið í ár sé honum ekki hliðhollt.

In a recent interview (http://www.ruv.is/frett/snaefellsjokull-ad-hverfa) Helgi Björnsson discussed how Snæfellsjökull is retreating rapidly and how this year will not be good for the “health” of the glacier.
