Today was a day of CTD’s, a live broadcast and a nighttime buoy visit. We are back to doing a CTD every degree, so Amy was a busy girl today (it gets even busier very close to the equator when she does CTD’s every half a degree). Our live broadcast was at 12:30 today as we are now on Central time. That was a bit dicey because John and I didn’t realize that the clock in the studio hadn’t been changed, so 20 minutes before show time, we were still thinking we had an hour and 20 minutes to go! Thank goodness I figured it out when I went down to eat and all the food had been put away because lunch was over!!

It just goes to prove, however, that preparation isn’t everything. We had a large “studio” audience (about 10-12 people standing behind the camera watching) and they all thought today’s broadcast was the best by far. All of the broadcasts will be put on the website as streaming videos in a few weeks when we return, so you can then decide for yourself. We had great guests: Clem, the Chief Steward who keeps our stomachs full of her yummy food (today’s delight: homemade bread pudding), Ensign Sarah Dunsford, Fred Bruns (the only original crew member since the KA has been working the TAO array), our bilingual trio of scientists Sergio Pezoa and Nuria Ruiz and our Ecuadorian observer, Juan Regalado, all topped off by a visit from oiler Ian Price (we’ve taken to calling him “Mr. Hollywood”). It was fun.

The nighttime visit to the buoy at 5°S 95°W was to check on the buoy’s anemometer. For a while now, the anemometer had been sending back low wind readings. The scientists weren’t sure if this was because there really were low winds in the area, or there was a problem. So, a little RHIB ride in the dark with a spare anemometer just in case did the trick. Turns out the bearings were bad in the old one, so they installed a new one (in the dark with spotlights in 8 foot swells). All in a day’s work for NOAA’s intrepid scientists Mike McPhaden, Brian Powers and Nuria Ruiz!

Question of the Day: 

Since we’re doing a CTD every degree, how often does Amy have to get up to do them? Or, how long is it between degrees of latitude going about 11 knots?

Answer of the Day: 

Mrs. Mackay’s class at Emory Elementary in San Diego CA were the first to come up with what the beam of a ship is: the width of the ship at its widest part (on the KA it’s 43 feet). Great job, you all!

Til tomorrow,
🙂 Dana
