We are high mountain people, hunters and artists,

Our view from this base camp is brilliant and clear.

Cold, thin air sweeps the rocky plateau;

You need a strong heart to live here.

 

Vicuña, guanaco, taruka our prey,

With razor-sharp points, upon them we close,

Then blaze up a fire, take rest, and prepare:

These creatures we skin to the toes.

 

Out of the ice age and up from the valley,

Testing the limits of body and spirit.

Descendants: a challenge before you stands tall;

Will you adapt, surmount it, or fear it?

 

Our tale has been weathered; you’re straining to see us

In smudges of smoke, in scattered remains,

Discarded tools, a wide, ancient landscape,

And one piece yet living: our blood in your veins.

The ENAM Seismic Experiment - Wed, 10/22/2014 - 11:11

After five days in North Carolina we have recovered all of the 80 stations. The stations have been recording for one month along two profiles. Now we are downloading the data at the instrument center at the East Carolina University in Greenville.  The last step is getting the equipment ready for shipping back to PASSCAL in New Mexico.

Beatrice (Bix), Dan and Ana working onsite at the first station recovered. Bix and Ana are checking the parameters of the Reftek with the CLIE, and Dan is saving the GPS waypoint of the recovery site.


Yanjun working on one of the stations recovered on the north line. He is performing a check with the CLIE to see the number of events recorded, the data stored on the disks and stopping the acquisition. He also checks all 3 channels on the L28 sensor. Once the acquisition has been stopped, the sensor can be pulled and the station is taken back to the instrument center.


A few of the Refteks at the instrument center. The upward cap indicates that the data have been downloaded.

We experienced wonderful weather during the past week working in North Carolina. The scenic countryside is filled with tobacco fields, cotton fields, and other crops. One lucky recovery team started the first day on Kitty Hawk Beach demobilizing site 101.

Sun-gazing

Geopoetry - Fri, 10/17/2014 - 10:00
 De Pontieu et al., Science 2014

Dopplergrams from the NASA’s space telescope IRIS (Interface Region Imaging Spectrograph) revealing detailed evidence of “twist” between the sun’s surface and outer atmosphere. These phenomena may play a role in driving the temperature difference between the sun’s surface (~6000 K) and the sun’s outer atmosphere (millions of degrees). The reason for this enormous temperature gradient is not fully understood (a puzzle known as the “coronal heating problem”). Image: De Pontieu et al., Science 2014

 

By Galileo’s careful hand, sunspot details are exquisite,

Through eye of forehead, eye of mind beholds what body can not visit.

If only he could see the sights now rendered from Earth’s outer space,

Ultraviolet sunscapes – Oh, to see his raptured face!

High above Earth’s atmosphere, IRIS probes the edges of our star,

A telescope in orbit, through its lenses, we see far.

Six thousand Kelvin screams the surface, roiling plasma, like hellish seas,

Hotter still, the sun’s corona: millions of degrees!

Mysterious, this source of heat that drives the solar wind our way …

High-speed jets, coronal loops and nanoflares may be at play.

What a thrill to gaze through space with spectrographic eyes,

Fueled by human wonder and a zeal to probe the skies.

Langseth limericks

The ENAM Seismic Experiment - Fri, 10/17/2014 - 01:19
As we approach the end of the cruise, I think this calls for a round of salty Langseth limericks.  It helps if you imagine a round of hearty “Aye, matey!”  and “Arr!” and such between each verse.

There once was the Langseth, a ship

Over wave and trough did she skip.

Many instruments aboard

To always record

Depth, gravity, mag – every blip.

There once was the Langseth, a vessel

Where in their bunks scientists nestled.

‘Til called to their shifts

Their heads they must lift

For with errors and logs they must wrestle.

There once was the Langseth, a boat

On her airguns the crew they would dote.

Oft while in a turn

Guns were brought up astern

To ensure best acoustical note.

There once was the Langseth, seacraft.

Where we launched XBTs down a shaft.

With each probe descent

To the lab data went

So that temperature-depth could be graphed.

There once was the Langseth, a fine tub!

Where the galley crew made us good grub.

But when seas ran high

Up in knots stomachs tied

And to keep the food down, there’s the rub.

There once was the Langseth, fair barge.

To collect seismic data her charge.

Streamer 8-km long

And four gun strings strong

She’s the fleet’s seismic dreadnaught at large!
