Rote - the service run sunset

We're done! All the stations have been checked, data has been downloaded, and the data and I are ready to return to LA. Nova's been great this whole trip and it would be hard to say goodbye, so instead we're saying sumpai jumpa lagi (see you soon!)

Since the last blog update, we've finished Flores and enjoyed ginger coffee with a sunset. Then, short stop in Kupang before we flew immediately to Rote. On Rote, we had two stations to do. One of the Rote stations is located on an amazing oceanside resort so we couldn't help but stay a couple nights there.

On the way to Ende, we found and tried fresh durian. Despite all the fear around the fruit, it was actually pretty tasty and didn't smell at all.

From Ende, where we enjoyed fried bananas and ginger coffee.

The calm before the final storm

Sumba's done and we're resting back home in Kupang. Tomorrow morning (Monday) we have an early flight to Lahunbajo in western Flores. That starts our last major hurtle - 5 stations on 1 island including a station with clearly bad data. We'll do what we can to try and fix it, but we may just decide to pull it and store the equipment to save time and money for the demobilization. Once western Flores is done, we'll touch down back in Kupang before going to the last island, Rote.

Couple quick videos we took on the way to our last Sumba site:

I got to be supervisor as Nova and the station manager put the tarp back over the station box.

Sumba day 1

We've just finished 2 stations on Sumba, leaving 1 for tomorrow. Stations looked pretty good, but all of these q330 stations seem to be giving me a curveball to test me. The first station had a little problem with the GPS - seems like it has a somewhat weak antenna and we had it pointed down. We flipped the antenna up and out and then forced the GPS to relock and bingo, we got it working happily. The GPS is really just used for a clock; the digitizer (q330) has an internal clock which drifts slightly. So, every few minutes to hours, it wakes up a GPS antenna to get accurate timing information from the satellites. The second station had one of its "booms" out of position. The instruments are basically a set of capacitive plates and what we really do is measure the voltage needed to keep those plates at a constant distance. The boom for one of these plates was not quite aligned within our tolerance zone, so we sent a recenter. But no response was seen on our handheld communication device (clié). So we did a manual recenter with the connecting box and it centered nicely.

Little video recorded between the stations. It is really striking how different Flores and Timor are compared with northeastern Sumba!

Indonesia service half done!

It has been quite a fruitful week since I met up with Nova and started the service in Nusa Tengarra Timur (NTT). We've serviced all 4 stations on Indonesian Timor, 2 stations on Alor, 2 stations in eastern Flores, 2 stations in Lembata, and just today did a quick round trip to/from the 1 station in Savu. Tomorrow we head for 3 stations in Sumba, then back to our homebase in Kupang before heading to 5 stations in western Flores, and then finishing with 2 stations in Rote. Much of the logistics is dictated by availability of flights and boat rides, but so far things have worked well. We're setting off very early, usually taking flights at 6 or 7am and then getting to our first site by 8am or so. Getting the sites done early in the day is working great. If we wait too long, the sun gets unbearable until the rains come down and make the roads impassible. So we're a little short on sleep, but not on Bintang (the local pilsner you can find in a large bottle).

Met some friendly guys working at the hotel in Atambua, which is a border town between Indonesian Timor and Timor Leste.

At lunch in Kupang at a traditional pork restaurant with our hero, Elen.

Probably one of the more unique highlights: we had a radio interview! Huge thanks to Nova for translating and making sure we didn't say anything incorrect :D.

On the little plane to Savu. I've never had so much leg room!

And now for the audio-video part of the blog:

After the first night of work in Indonesia. We had two sites; the first was great, but the second was during a downpour, which of course ended once we were done.

From the road, en route to our second station on the second day in Lelogama. Turns out we didn't have the right equipment, so just did a quick power check and then returned a couple days later.

From the boat between eastern Flores to Lembata.

In the radio station, just before the live broadcasting!

Videos from the road

Just wanted to post a few short video clips. This first one is just to give you a sense of the ferry ride between Dili and Ocuessi:

This next one I recorded while waiting for Teo and Atoy to get me in Ocuessi:

Next was in the hotel room in Soe after servicing two stations (one in some pretty bad rain!)

Finally, on the way to our last station in west Timor. The video is surprisingly steady considering the road conditions ^_^.

Timor Leste completed and western Timor nearly done!

Checking in from our home away from home in Kupang. We're one station away from being completely done with the island of Timor and plan to get that done Sunday. Tomorrow/Saturday we're heading to/from the island of Alor to take care of stations there. Looks like our schedule is pretty well setup to island hop around for the next week or two.

Met a new friend in Dili. He spoke a little English and helped me get on the right boat.

Met some new friends in the hotel at Atambua.

What's a field deployment without q330's in the hotel room (Go Trojans!)

Waiting in Dili

We're unable to get to our last two stations until Monday, so I'm just waiting around in Dili. This has given me a little chance to check some data and I thought I'd make a nice little record section of a big earthquake from the Bonin Islands which was picked up on the last trip.

Each wiggle is a different station in the Banda Arc array. They are sorted by distance and filtered to show signals from 10 to 100 seconds period. You can clearly see the first arriving P wave on the far left, then a series of bumps associated with bounces off the core. Eventually there's the S wave and then a simple surface wave. 

I had a little walk around the north shore of Timor and noticed some beautiful outcrops. Looks like a blueschist faces schist; this is part of the mélange unit within the Banda Terrane. I'm somewhat reminded of the Franciscan unit found throughout California and makes me wonder if there's a similar tectonic history, just shifted in time.

The water is calm and beautiful. I especially love the mountains jutting out into the sea.

Finally, here's a couple "talk to the camera" videos I took as I walked around the north coast. Sorry they're a bit shaky; my phone is not an ideal video camera.

Back to Dili and wifi after a tour of Timor Leste with Teo and Antouy. We collected 4 more stations of data (all looking good!) and helped bus tens of children to school on the way. The views were just spectacular and the food is great. We felt an earthquake Thursday night while staying in Same; it was a magnitude 5.5 in the Timor sea (just south of Timor). For better or worse, it was after we had collected the data, so now I won't be able to see seismograms of the event until Monday night when we collect the data from the last two Timor Leste stations!

Atauro Island Adventures

Rob and I made a whirlwind trip to Atauro island in just one day to retrieve the data from station TL03.




It is the noisiest station (no surprise from the photo here!!), but is probably our favorite because of the beautiful location and wonderful transport 35 km across the sea from Dili with Compass Charters.







Despite being such a noisy station, it still records beautiful seismograms like the one Rob is looking at (10 minutes after we switched out the data cards!) from the M6.7 January 3rd event from India.
