Abstract

 Here's a copy of my AGU abstract.  I couldn't figure out how to control font size (wierd thing to be absent from the formatting panel?), so the format is a bit off.  I'll provide an update on my progress soon.

Yahtse Glacier, which feeds into southcentral Alaska's Icy Bay from the St. Elias Mountains, produces extensive regional seismicity. In order to better understand the production of glacier-generated seismicity at this temperate tidewater glacier, we installed 15 seismometers, 3 infrasound sensors, 4 time-lapse cameras, and 10 GPS stations at both land and ice locations around Yahtse Glacier's terminus in early summer 2009. During the first week following the deployment, we kept a detailed observer record of calving, glacier noise, and other activity in the vicinity that might manifest in the seismic records. Side-by-side comparisons of the instrument and observer records reveal seismic characterizations that overwhelmingly pervade all observable glacier activity at and near the terminus, and provide evidence of energetic ice events that are hidden from visual observation. We will present methods to characterize and distinguish different types of icequake events, including sub-aerial and sub-marine calving and upstream events (both audible and inaudible), which are critical developments for the interpretation of glacier seismicity over a longer time interval than is practical through first-hand observation.
 

 

 

Looks great!  Did you

Looks great!  Did you contact Rick Aster, or look at any of their work of the seismics of glaciers etc?  Just neat that your project aligns with the talk Rick gave at the orientation.  Maybe you could post an mp3 of the events (sped-up of course) like Rick included in his talk.  I would certainly be interested in giving them a listen.

Just as an aside, you can control the font sizes by changing the font styles.  Since that wasn't obvious, I went ahead and added a font size drop-down.

Thanks for the drop box. 

Thanks for the drop box.  I'll check out some of Rick's work.

Yahtse Glacier, which feeds

Yahtse Glacier, which feeds into southcentral Alaska's Icy Bay from the St. Elias Mountains, produces extensive regional seismicity. In order to better understand the production of glacier-generated seismicity at this temperate tidewater glacier, we installed 15 seismometers, 3 infrasound sensors, 4 time-lapse cameras, and 10 GPS stations at both land and ice locations around Yahtse Glacier's terminus in early summer 2009. During the first week following the deployment, a detailed log of calving, glacier noise, and other activity in the vicinity that might manifest in the seismic records was kept. Side-by-side comparisons of the instrument and observer records reveal seismic characterizations that overwhelmingly pervade all observable glacier activity at and near the terminus, and provide evidence of energetic ice events that are hidden from visual observation. We *remove will* present methods to characterize and distinguish different types of icequake events, including sub-aerial and sub-marine calving and upstream events (both audible and inaudible), which are critical developments for the interpretation of glacier seismicity over a longer time interval than is practical through first-hand observation.

 

**Just a few little suggestions of voice. Not really that important with the first two, but the last one should definitely not have the will in there. Sounds much better and stronger without it.

Thanks Rob.  I'll stick

Thanks Rob.  I'll stick with active voice in the first part to be consistent with the rest of the abstract, but I agree about the last part.
