Before I left home for this seafaring adventure I had been working on some curtains for the kitchen. I got these two great pictures on my phone. Matt had found a curtain rod. So now my kitchen has some mushroom curtains.  I do think they need some pressing and possible adjustments to look a little better, but not too shabby.

Science log 3- out to sea and back

We arrived at the deployment site at 5:30 AM. All hands we on deck and by 6:30 the wave glider was in the water and quickly moved on its eastward path. Throughout the course of the day the glider's speed was registered at 2.1 to 3.0 knots. This surprised just about everyone on-board the ship. The average, or expected speed, was between 1 to 2 knots.

So the deployment went smoothly. The retrieval, on the other hand did not. You may be asking, but why? Well the gulf is always full of surprises in weather, especially in the fall. So when we left the dock it was kinda overcast and then for the whole day yesterday it rained, either a drizzle or a deluge. The storm caused 4-8 foot swells and a very fluid boat, or what everyone called 'the rockin' ryan'. Luckily I took everyone's advice and started taking dramamine 2 days before deployment. I got kinda queasy at one time, basically the first time I tried sitting down on my computer to write the daily report. I took a video of the 'box' I call the office, but I can't seem to get my computer to play it. Maybe I can add it through another computer. The portable office is situated on the back deck very close to the deck edge. We had wave crashing into our window every 10 or so minutes and our chairs were rolling around, even with duck tape on them.

The day seemed to be going pretty slowly. Especially since I woke up at 5:30 and the peak excitement of the day happened at 6:30 am. However, at 4:00 pm, the CSIRO scientists came knocking at my office to inform me that the winch they used to deploy the vertical cast equipment had broken, or more specifically, there was a crack in the shaft coupling sleeve of the sprocket. Immediately I had to call the manufacturer and relay that we needed a replacement sprocket for us at port on Saturday. This call required a photograph due to my inability to properly describe all things mechanical. Based on the winch being out of commission we made a decision to go ahead and head back to port. On our way back in we decided to try to find the Wave glider and retrieve it. Finding that little sucker was tricky, especially since it had gotten dark and the storm had escalated (along with the size of the waves). So the wild goose chase continued and when we finally found it it took 2 hours to catch the glider and get it onto the deck. It was almost like the little robot had a mind of its own, always tacking when we got close to it. I felt like I was in a wild adventure with big seas, rain, and a pitching boat- a regular most dangerous catch. After the excitement of getting the wave glider on-board it was almost 9:30 pm. I had a few hours before my shift was up and we headed in to Theodore. The boat continued to pitch all night and I slept in till 9:00!

Science log 2- Setting sail

One of Liquid Robotic's Wave gliders

Last night at around 9:00 we finally moved out of the Theodore dock, down Mobile Bay, and into the great expanse of the gulf. This first leg of the cruise will last 2 days, Thursday night to Saturday evening. The main purpose of this short cruise is to release the wave glider into the gulf. The wave glider is an autonomous ocean vehicle, created by a company called Liquid Robotics, and commonly described as a robot. This robot is slightly different from most in that it is uses solar energy generated by the solar panels ontop of the 'surfboard' body to power the electronics and has no motor, but is powered by waves.

The glider converts wave motion into forward thrust, thus propelling itself forward. It can travel from .5 to 2 knots depending on the roughness of the sea. The amazing thing about this piece of equipment is that it can be released into the ocean, travel long distances, and collect an array of data, ranging from weather and water temperature, water quality, marine mammal vocalizations, and even take pictures. The plan is to deploy the wave glider early in the morning and then check on it on Saturday on the way back into port. At the same time, vertical cast will occur continuing the collection of water quality data.

So after going to bed (at 12:45), I set my alarm for 5:30 in order to get up and watch the deployment. So I crawled out of bed, ate some bisquit and gravy and a to-order omellette (I swear I will gain weight with this sedentary ship life and hearty ship food), and stepped onto the deck. [Safety moment: When on the slippery deck, we must wear a life jacket, hard hat, and steel toe boots].

Once the sun finally peeked over the horizon and the rain began to drizzle we set to work deploying the glider. It was quite successful and we all watched in excitment as it moved quickly away.

All and all, I think it was a succesful deployment. Now to take a nap before my 12:00 shift.

Ship science log- Day 1

I have decided to change the focus of my blog from the recent craft documentation to a log of the the activities I am going to participate in during the next 2 weeks. I will be the representative for a science vessel that has been deployed in the Gulf of Mexico for the relief efforts after the spill. I have to admit I feel slightly overwhelmed with all the responsibilities I have to take-over. My colleague and friend, Lawrence, has been doing this on and off for a total of 6 weeks so he has the drill pretty down pat. I, on the otherhand, am truely unexperienced, but hope to gain some experience over these next 2 weeks.
I arrived on the Ryan Chouest on Tuesday evening at 6:00. The ship was commissioned in 1996, it has been traveling and working in the gulf ever since. There are 24 people total on the ship- a captain, first mate, several deck hands, two cooks, four geotechnician running the echo sonar, four scientists from CSIRO, a GSI expert, and myself. It is a dynamic crew and the ship captain runs the activities on the ship very well.

Tuesday I simply arrived on the ship, meet everyone, and then made a late night supply run at wal-mart and lowe's. So for the rest of the blog I will write a little science log so that everyone can keep up with what is going on and get an understanding of ship life.

This ship has been used for this particular mission for about 3 months. The primary purpose is to monitor the detection of hydrocarbons at varying senistivities at surface depths to depths of ~100-130 m. The current instrument platform has an array of sensors that together detect and differeientate hydrocarbons in marine environments. So far the team has surveyed over 7000 nm in the Gulf. Below is a map of the previous ship cruises that have occurred during the past 3 months.

During my portion of the cruise we will also be deploying a relatively new technology, called wave gliders. These wave gliders also detect hydrocarbon values in addition to CTD information. The deployment should begin late Thursday afternoon.

Biking in the heights

I like the urban biking options in Houston. This trail runs from the far northern part of the heights and then goes towards downtown. I am not sure when they will extend it all the way downtown or if they will, but I sure hope they do. It is nice to have the little urban biking adventure. We could see sky scrapers and turtles and fish and lots of trash all wrapped in one.

Impromptu baby bib

So I had some scraps leftover from my pajama pants and a neighbor who had a little baby boy recently. Put those two together, with the fact that I didn't feel like knitting anything, and I decided to sew a little bib. It was fun. I got the pattern from on-line, bought some flannel for the backing and made a little bib.  I now need to attach the snap closure.

Sew III- Pajama pants

I took third sewing class. I made a pair of pajama pants with pockets!  It was pretty fun and was a two part class. I feel a little more confident at my ability to make something from a pattern, but still not confident enough to do it by myself. I met a nice woman in my class and think we will be pretty good friends. It is always nice to drink wine with someone and talk about something other than work and geology. I think she and I will try to make some projects together to improve our skills and confidence.
