Volunteers Sought for Christmas Bird Count





Excerpt from
yourdailyjournal.com 


ROCKINGHAM — The National Audubon Society is inviting Richmond County birdwatchers to participate in the longest-running citizen science survey in the world, the annual Audubon Christmas Bird Count.

Beginning Sunday, hundreds of birders and nature enthusiasts across North Carolina will take part in this long-standing tradition where data collected has helped to shape influential conservation efforts nationwide.

As North Carolina’s landscape continues to evolve with changes... the data collected during the annual Christmas Bird Count is crucial to understanding the health of native and migrating bird populations throughout North Carolina. During the 2013 CBC, five snowy owls were spotted from Asheville to Wilmington, and local citizen scientists were on hand to detail the rare event.

North Carolina’s birding circles are some of the top performing in the country, and last year, a record 51 counts across the state reported 1,113,012 individual birds from 225 species.

“In a state where inspiring conservation action is vital to the health of birds facing the damaging effects of climate change, Audubon North Carolina is excited to be a leader in statewide conservation efforts,” Executive Director Heather Hahn said in a release. “As climate change continues to affect populations of the brown-headed nuthatch, American oystercatcher, wood thrush and many more iconic species, the data collected during this annual event becomes even more important to ongoing efforts to protect our birds.”

Each year, the Audubon Christmas Bird Count mobilizes more than 70,000 volunteer bird counters in more than 2,400 locations across the Western Hemisphere. The Audubon Christmas Bird Count utilizes the power of volunteers to track the health of bird populations at a scale that professional scientists could never accomplish alone. Data compiled across North Carolina will record every individual bird and bird species seen in a specified area, contributing to a vast citizen science network that continues a tradition stretching back more than 100 years.

Birders of all ages are welcome to contribute to this fun winter tradition and nationwide citizen science project, which provides ornithologists with a crucial snapshot of native bird populations during the winter months. Each individual count is performed in a count circle with a diameter of 15 miles.

At least 10 volunteers, including a compiler to coordinate the process, count in each circle. The volunteers break up into small parties and follow assigned routes, which change little from year to year, counting every bird they see. In most count circles, some people also watch feeders instead of following routes.

Early Earth less hellish than previously thought

Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates.

This alternate view of Earth’s first geologic eon, called the Hadean, has gained substantial new support from the first detailed comparison of zircon crystals that formed more than 4 billion years ago with those formed contemporaneously in Iceland, which has been proposed as a possible geological analog for early Earth.

The study was conducted by a team of geologists directed by Calvin Miller, the William R. Kenan Jr. Professor of Earth and Environmental Sciences at Vanderbilt University, and published online this weekend by the journal Earth and Planetary Science Letters in a paper titled, “Iceland is not a magmatic analog for the Hadean: Evidence from the zircon record.”

From the early 20th century up through the 1980’s, geologists generally agreed that conditions during the Hadean period were utterly hostile to life. Inability to find rock formations from the period led them to conclude that early Earth was hellishly hot, either entirely molten or subject to such intense asteroid bombardment that any rocks that formed were rapidly remelted. As a result, they pictured the surface of the Earth as covered by a giant “magma ocean.”

This perception began to change about 30 years ago when geologists discovered zircon crystals (a mineral typically associated with granite) with ages exceeding 4 billion years old preserved in younger sandstones. These ancient zircons opened the door for exploration of the Earth’s earliest crust. In addition to the radiometric dating techniques that revealed the ages of these ancient zircons, geologists used other analytical techniques to extract information about the environment in which the crystals formed, including the temperature and whether water was present.
Since then zircon studies have revealed that the Hadean Earth was not the uniformly hellish place previously imagined, but during some periods possessed an established crust cool enough so that surface water could form – possibly on the scale of oceans.

Accepting that the early Earth had a solid crust and liquid water (at least at times), scientists have continued to debate the nature of that crust and the processes that were active at that time: How similar was the Hadean Earth to what we see today?

Two schools of thought have emerged: One argues that Hadean Earth was surprisingly similar to the present day. The other maintains that, although it was less hostile than formerly believed, early Earth was nonetheless a foreign-seeming and formidable place, similar to the hottest, most extreme, geologic environments of today. A popular analog is Iceland, where substantial amounts of crust are forming from basaltic magma that is much hotter than the magmas that built most of Earth’s current continental crust.

“We reasoned that the only concrete evidence for what the Hadean was like came from the only known survivors: zircon crystals – and yet no one had investigated Icelandic zircon to compare their telltale compositions to those that are more than 4 billion years old, or with zircon from other modern environments,” said Miller.

In 2009, Vanderbilt doctoral student Tamara Carley, who has just accepted the position of assistant professor at Layfayette College, began collecting samples from volcanoes and sands derived from erosion of Icelandic volcanoes. She separated thousands of zircon crystals from the samples, which cover the island’s regional diversity and represent its 18 million year history.

Working with Miller and doctoral student Abraham Padilla at Vanderbilt, Joe Wooden at Stanford University, Axel Schmitt and Rita Economos from UCLA, Ilya Bindeman at the University of Oregon and Brennan Jordan at the University of South Dakota, Carley analyzed about 1,000 zircon crystals for their age and elemental and isotopic compositions. She then searched the literature for all comparable analyses of Hadean zircon and for representative analyses of zircon from other modern environments.

“We discovered that Icelandic zircons are quite distinctive from crystals formed in other locations on modern Earth. We also found that they formed in magmas that are remarkably different from those in which the Hadean zircons grew,” said Carley.

Most importantly, their analysis found that Icelandic zircons grew from much hotter magmas than Hadean zircons. Although surface water played an important role in the generation of both Icelandic and Hadean crystals, in the Icelandic case the water was extremely hot when it interacted with the source rocks while the Hadean water-rock interactions were at significantly lower temperatures.
“Our conclusion is counterintuitive,” said Miller. “Hadean zircons grew from magmas rather similar to those formed in modern subduction zones, but apparently even ‘cooler’ and ‘wetter’ than those being produced today.”

Schumann Resonance And The Time Speeding Up Phenomenon

Time is actually speeding up (or collapsing). For thousands of years the Schumann Resonance or pulse (heartbeat) of Earth has been 7.83 cycles per second, The military have used this as a very reliable reference. However, since 1980 this resonance has been slowly rising. Some scientists believe that it is rising faster than we can measure seeing as it is constantly rising while measuring.This is from a member of the Physics Forum:"The universe is expanding; interstellar distances [...]
