Test Station 1

We’ve arrived at the first test station. The day began around 2AM for the plankton tow team led by Deb Steinberg (Virginia Institute of Marine Science) . By all accounts all went well.  Deb came around the main lab proudly showing off specimens from the first tow that included jellyfish about 4cm across and a jar of plankton. (see photos in the gallery) I was up myself at 5AM for a scheduled test with the SeaViewer (underwater cam). Assisted by Comm-E-T David G. Ziskin, I am happy to report that we successfully deployed (and retrieved) the SeaViewer! We descended to about 40 feet and drifted at about a 30 degree angle, being careful to stay in a safe zone (away from thrusters and propellers). We were able to see the bottom of the ship and many unidentified objects moving close to the camera on the monitor. Sadly, in all the excitement I forgot to “save” the video, so I can’t tell you exactly what we saw!! However, with lessons learned, we have a better plan for our next deployment :)

All of the science teams had test runs today that included: CTD casts; the Multicorer (which collects soil samples); plankton tows; hand nets and surface pumps. I spent the morning processing water column samples with Tish Yager. The entire lab was a busy place as everyone tested equipment and processed samples as well.

Our next station is about 17 hours away and it will be a very busy, long day.

Question of the Day

  • Do the bacteria in the water make us sick?

    Only a few of them.  Bacteria are in every habitat on Earth, growing in soil, hot springs, radioactive waste, water, as well as in organic matter and the live bodies of plants and animals. Bacteria recycle nutrients, with many steps in nutrient cycles depending on these organisms, such as nitrogen fixation.
