Major Arenal Pyroclastic Flow

Mon, 16 Jun 2008 08:05:11 -0600

Latest report from the Smithsonian / OVSICORA-UNA:

4 June-10 June 2008

OVSICORI-UNA reported that an incandescent avalanche descended Arenal's SW flank on 6 June producing an 800-m-long scar and depositing a wide debris fan at the base of the volcano. A plume of dust, ash, and gas drifted W and NW, depositing fine ash in a small area downwind. The plume panicked tourists and park rangers 2 km away to the W. The park was immediately closed for the day and the tourists were evacuated. According to a news article, another incandescent avalanche descended the SW flank on 10 June and generated an ash plume. Authorities evacuated people in the area.

Legend added to the maps

Thu, 05 Jun 2008 20:32:17 -0600

I have just added a legend to the maps. Although I might adjust the maps further, they are now complete.

I have also adjusted some parameters for the MapServer layers (base map, satellite image, synthetic streams) to make them load more quickly. The improvement should be more noticeable on slower internet connections.

So Much Work to Do...And So Little Time

Wed, 04 Jun 2008 13:06:20 -0600

Today we met as a class to discuss what each group needed to do, which included: making an inventory of data, creating a plan for results, discussing conclusions and overall paper format, and turning in field equipment. We also discussed what our final paper should include (Intro, Methods, Results, Conclusions, and Literature Cited), and what each section of the paper should include. Then our group continued data analysis, outlined our results, and wrote up our results section. And we got back our graded annotated bibliographies, which will be a big help when deciding which sources to use in our final papers.

Map Update: New spring icons and flow diagram

Wed, 04 Jun 2008 09:21:59 -0600

The spring icons have been updated. The 'hot spring' icon has been made clearer, and a new blue circle icon has been used for the cold springs. Blue&white crosses have been used for stream points (the sample point and the measured boundary crossing). These are now connected with a simple flow diagram. This is a simple line drawing that shows how water flows between these points.

We are back - and welly pictures

Tue, 03 Jun 2008 15:18:45 -0600

Yes we all made it back safe and sound, despite a quick sprint across Bush International Airport to meet a tight connection.

The road data is now complete on the map, and the building photos have also been added. I have a few more map changes to add. Student reports will also be uploaded after they have been completed and graded.

Attached are a group of photos from Johanna's "Welly Wanging" competition that closed the field work on Saturday afternoon. I'll leave it to Johanna to give a commentary. Giovani and Dr. B were judges, and Steve & Debbie made up the out-field spectators.

Thank you

Tue, 03 Jun 2008 12:12:00 -0600

This morning we waved a fond goodbye to a great group of humans. What a wonderful experience. We want to thank Dr.Brown, Richard Marsden, all of the students and Geovany for their hard work-rain or shine. A special thank you to the parents and the University of Dallas who trusted us to provide these young people with the opportunity to share our dream. We hope this experience has planted the seeds that may someday grow into solutions for how we, the human race, can live symbiotically with Mother Nature.
Muchas Gracias,
Debbie and Steve

End-of-season games

Tue, 03 Jun 2008 08:48:00 -0600

The course's field assistant, Johanna Weston, coordinated the amazing First Annual Welly-Wanging competition. Students competed by flinging their field-issue rubber boots off the their right foot without using their hands or kicking the boot. Competitors were judged based on distance in a best-of-three competition.

Our two winners were Noah Jouett (Best distance: 18 meters) and Mary Boyum (Best distance: 16 meters). The winners (dubbed the winning wangers) were garlanded not with a traditional laurel given to Olympic athletes, but with a balsa leaf worn on their heads. We'll post more photos of the competition later, but here's one taken by Debbie of Leaves and Lizards. She and Steve, along with our guide Geovany, were our special guests (and only spectators) for the competition.

End of fieldwork, start of data analysis

Sun, 01 Jun 2008 09:16:22 -0600

All three groups finished their fieldwork yesterday, and so far the data are fairly complete and should give them quite a lot to analyze when we return to Dallas tomorrow. Steve and Debbie have told us that they have gotten more than they expected from our group, and we hope to have even more to tell them about their property after more analysis is done.

The students have a free day today, and some will head out for whitewater rafting, while others are doing a canopy zip-line tour. They are anxious to see a little more of the area around us, and are thinking a lot of their friends and family and what to bring home as gifts. Last night most of the students went to a local church in Monterrey for mass, and enjoyed the experience and the differences in Mass her compared to back home, including for a while bats circling in the top of the church.

We will have them post one more blog entry before we leave, and some photos of yesterday's welly wanging competition.

Additions to the Map

Sat, 31 May 2008 09:59:52 -0600

The mapping group has almost completed the field work and only has to retrieve the HOBO sensors and to process the remaining data. All the panoramic photos were collected during yesterday morning's excellent weather. Noah has stitched all of them, but they still need to be resized and have their north markers added.

The final plant areas were also collected yesterday. All plant areas are marked on the map.
We need a key, but for now: red = monoculture, yellow = mixed species, and pink/magenta = ornamental.

The springs and other water points were added using the 'hot spring' symbol. We need more symbols, and the hot spring is not too clear. I shall fix these symbols when I return to Irving.

The road data is ready to add, and we should have it up soon.

Panoramic photo has been resized and had its north marker added. This has been uploaded to the panoramic photo section of the site, as an initial test. The others should follow soon.

Another addition is the Arenal walk (zoom out to Arenal and surrounding area) - click this to see the group photo on the lava flow.

It's a beautiful day!

Finally, after days of forging through the rain and mud, we had some sunshine. For the mapping group this weather was ideal for taking panoramic photos at all of the bird group's points throughout the property. We got a little bit of a late start, around 6:30am, but we still had most of the photos taken before breakfast. A complete 360̊ panoramic image requires 18 individual fames. After all of the frames were taken, we stitched them together using software on a pc. We also mapped two final areas for the plant group and we think that we now have all of the data we need for the map. Now, with a lot of help from Richard, we will begin putting all of the pieces together for the website.

Around lunchtime we walked to the famous Super Kike. The weather was barely holding out for us, but we all made it before the big afternoon rain. However, because we went during the typical siesta time, the store was closed. We thought that we were going to have to walk right back to Leaves and Lizards when Geovanny came roaring up the hill on his motorcycle. He, of course, knew the owner of the store and convinced her to open early for us. She was very nice and we got all of the salsa vegetales(our new favorite condiment) and Costa Rican coffee we could carry to bring home to the USA. We also got some ice cream and ate it right outside the store. We made it back to our cabins just as the sky was opening for the afternoon rain.

More than Expected...Plus Ice Cream!

Fri, 30 May 2008 20:22:07 -0600

This morning we woke up to a sunny, not rainy, morning. It was absolutely wonderful to walk around with Geovany and his friend, Ulises who is a plant expert. Ulises and Geovany worked together to help us identify some more of our unknown plants. We also were able to finish mapping sloth valley and the cabin areas. After walking to the Super Kike, we started our quadrats. By dinner time we had finished 8 out of 12 quadrats (which was more than the 6 we expected to complete). We are very excited to wrap up our plant project tomorrow.

Its a lovely day in the neighborhood

Fri, 30 May 2008 20:11:48 -0600

Today was a beautiful day, very sunny and hot! We slept in until breakfast and did the first half of our bird counts after we ate. Our first two counts were done without Geovani or Dr. Brown, we are getting much better at identifying species! It has been concluded that the three of us have officially "stepped into the dark side", according to Debbie our host. We find ourselves always noticing birds wherever we go, even during our free-time, rather than relaxing and napping we sit on the porch and look for new bird species. Today, we were very excited to discover three new species of hummingbirds that we had not seen before. It is raining now and we are analyzing data before we go back into the field to finish our bird counts for the day. Tomorrow we will be welly wanging!!
