“80’s Day”
by -- January 29th, 2013

Hi, it’s Jennifer again! Since my last post, I have completed one 4-day temperature shift experiment and started a second before the ocean temperature gets too cold. Our goal is to retrieve our sample water from a cast when it is approximately 18 degrees Celsius because that is where the two dominant ecotypes of Prochlorococcus are equal in number. Each day of an experiment, we sample three bottles out of each of the three incubators (one control, one 2 degrees warmer and one 2 degrees colder). Then I filter all of the samples and use a fluorometer to find the chlorophyll for each sample. The second experiment is a repeat of the first, so we can compare the data and the graphs we made for each.

Molly and I have also been continuing the experiments with our iPads. The sea surface temperatures recorded with our iPads have been matching the temperatures recorded by the ship almost perfectly so far!

Today was “80’s Day,” so we did our best to dress for the decade with what limited resources we have on the ship. We even listened to some 80’s music while we did our sampling in the lab.

Otherwise, we enjoyed a warm, sunny day. For lunch, some of us went up on deck to have a picnic to enjoy the nice weather since we’re headed back north into the cold now.

Here are just a few of the beautiful sunrises and sunsets we’ve been able to see! They’re absolutely amazing when only surrounded by sky and ocean.

    Your research cruise has been a remarkable journey to follow. I’ve enjoyed learning about the science and viewing all of the wonderful pictures everyone has posted. I hope the research is a success and you all have a safe trip home!
