OPENING QUESTION:
Please work with your team to:
1) Compare (which means, what again?) tsunami waves with 'regular' ocean waves especially in terms of our main wave characteristics
2) Contrast (which means, what?) tsunami waves with 'regular' ocean waves, again, especially in terms of our main wave characteristics
Let's please have a *volunteer* who just happens to be designated by the color green to lead the conversation with the class for compare and then another volunteer designated by the color orange to lead the conversation for contrast
WORDS OF THE DAY:
Tsunami Characteristics:
Wavelength
Amplitude
Speed
Frequency
WORK OF THE DAY:
Did your conversations about the opener involve the difference in how tsunami waves are caused compared to ocean waves?
Did you talk about the BIG 3?
If you didn't, please do so now.
Let's have a volunteer designated by the color BLUE to come up and lead a conversation to make sure we are all good on the causes of tsunami vs 'regular' ocean waves!
I'm out today so please attend to the following:
Make sure you know how to transfer your graph from google sheets to your lab report. A screen shot works nicely here so if you don't know how to do that, make sure you learn from your team today.
Period 3:
Please work with your team to review our lab specifications for this project. Period 04 had some suggestions/comments and I have updated that HERE
Please work on finishing your labs. Remember, I want you working solo on your discussions.
Period 4:
We found out yesterday that finding the amplitude of the tsunami waves caused by the Tonga explosion was kind of difficult since they seemed pretty small.
There are several (?) different ways that you can assure that part of your data stands out and WILL allow you to make those measurements.
Work with your team to solve that problem. It might be helpful to make a copy and try different approaches as 'proof of concept'. If worse comes to worse you can always go back to the data and try again. Remember, each time you go through the exercise of creating one of those graphs it goes much, much fast.
Please don't try for a few minutes and then give up.
Then continue working on your lab-- please work solo on the discussion sections.

Measuring wave characteristics for a low amplitude tsunami lab!
I put together this lab as part of a project with the University of Washington and the STEM folks at West Sound Tech.
Our goal is to see if we can measure wavelength, frequency, speed and amplitude using state-of-the-art underSea instruments located off the Pacific Northwest Coast as part of the Ocean Observatories Initiative (OOI)
Take a moment to sketch your home showing JUST the items connected to the internet.
What resources MUST be present in order to do that?
Now image having to place those resources on the bottom of the ocean-- hundreds of feet below the surface. What problems might be associated with that?
Now please take a few moments to briefly tour the OOI website. It is very, very, remarkably cool!
Now we'll get into the good stuff-- THE DATA!!!!
The OOI Data Portal is a doorway into a rich treasure trove of data from the ocean floor and the surrounding water column. The image above shows just one instrument package from one of the 10 different locations monitored by the Ocean Observatories Initiative on or near the Juan de Fuca Plate.
Let’s go take a look at that data portal now.
Notice in the upper left hand corner is a list of the instrument packages (shown in the graphic above):
Go ahead and choose one of the research areas there.
Then Choose the Instrument package in the Lower left
There are a dozen or so research locations. We need to check each of those locations to see if they have the sensor that we need. Not al ll sensors have historic data, and even some of those that indicate that they do, don't work.
The OOI first went online in 2012 or so, but not all sensors have data going back that far.
Our task for today is to build a list of working sensors that we will then use to do our lab.
We will also build a list of tsunami generating earthquakes that fit in our date range.
There are 3 different pressure sensors:
PREST
PRESF (I think?)
CTD (Connectivity/Temperature/DEPTH
Now Please go to the NOAA Tsunami Tracking Site HERE and find candidate earthquakes that fit in our eligible data date range.
