Back at it!

Hello there.

It’s been a while, but I’m heading back out to sea! I leave on Monday for San Diego and we head out to sea on Wednesday. I’m going to try to blog from sea, but as always its hard to predict what the internets will allow out in open water.  No hydrothermal vents this time, but we will be investigating an oxygen minimum zone off Baja. I will post again soon with some more info about the cruise location and research goals.

This post is primarily to test out an automated system for updating my facebook and twitter feeds.

This is just 1 shipment of stuff I will be bringing with me, and I’m the only person going from my lab.



the science begins!

I am back to feeling 100% and have even had an apetite for the last two meals (which were awesome by the way)!

Just watched Alvin launch… very cool.  It is quite an involved process as you might imagine.  In addition to the folks on deck watching and directing the process there are two swimmers who stand on Alvin as it gets lowered into the water.  The swimmers do various safety checks before they clear the sub to dive and are then picked up by a Zodiac boat.

We collected bottom water last night with a CTD (conductivity, temperature, depth) cast.  A carousel of 10 liter bottles with top and bottom held open (this is the CTD) is lowered by a large winch.  From inside the computer lab we can watch a screen and see various water parameters as the CTD descends.  When it gets to the desired location (last night that was about 50 meters above the bottom) we tell it to release the bottle lids and bottoms – capturing 10 liters of bottom water per bottle.

Today we used the water we collected last night as well as some creative engineering and troubleshooting to get our water system pumping so that it is good to go as soon as we have our sample and can start our experiments.  Octavian has been an enthusiastic helper throughout the process.  However, his favorite part so far has been sitting on the bow and staring off over the ocean!
