Things are progressing very rapidly now as we prepare to depart for Costa Rica in less than 2 weeks time. This is also a very busy time for all of us as all of our classes are presenting us with midterms or finals or mid semester project reports. At the same time, I am pleased with the progress that we have made over the last week or so. The development of the CO2 sensor looks promising at this stage and we are hopeful about completing the building stage this coming weekend. We have also set ourselves a new goal: that of integrating a ph sensor to make alternative models of CO2 emissions from the lakes.
Meanwhile, we got an interesting e-mail from Don McFarlane this week. For those of you who are not familiar with Don, he is the science lead on this project. He works at Keck Science and brings a rich knowledge of Costa Rica and its volcanoes to the team.
In his e-mail, he sent us the following picture (taken from BBC):
This is a picture of Poas lake erupting last week. According to the BBC article that Don referenced, the lake is currently erupting and erupting violently. So much so, that this eruption was the worst in Costa Rica this year.
Here is an excerpt from the article:
“Earlier this week, Poás in Costa Rica had a small eruption likely related to water flashing to steam in the heating crater lake area. This eruption ended up being the largest so far in 2014, but these types of explosion are fairly common at the Costa Rican volcano. That being said, María Martínez Cruz (OVSICORI) said that the size of this eruption, with a plume that reached 300-meters, is not too common at Poás. This could suggest that more heat is being fed into the upper reaches of the volcano. The webcam at Poás captured the eruption as it occurred, spreading ash mainly within the crater area. If check out the webcam at night, you can see some intense incandesce that betrays the magma just beneath the surface at the volcano.”
