Putting a Face with a Name – – Written by Leandra Darden

Science is a unique profession because your career is based almost solely on your name. As a student you have to read many scientific papers and it is easy to forget that the author of that paper is still a person. These researchers have ambitions, passions, families, and people who have helped them along the way. The Coastal Waters Consortium has many researchers at all levels and we wanted to feature some of them to show off not just their work, but their personalities as well.

Dr. Gregory Olson is a Research Associate II in the Response and Chemical Assessment Lab under Dr. Ed Overton. Currently Dr. Olson is working on sediment analysis for trace crude oil components as well as biomarker analysis and fingerprinting for specific crude oils.

Dr. Olson reports, “One of the more surprising things I have seen is the resiliency of sequestered oil in coastal marshes. Some of the samples we analyze show signs of delayed weathering. This has impacted my work with utilizing oil fingerprinting techniques to get a better idea of what kind of oil we are seeing in these samples.”

His work for Dr. Overton has not only helped understand the oil Dr. Overton’s lab is studying, but clarify some things for other researchers within the CWC. As scientists it can be difficult to explain to family members and friends what they do for a living. Often the people close to them have a vague understanding of they day to day life at work. Dr. Olson’s family believes he makes “environmental tea” and then runs it on the CSI (TV show) machine looking for pollutants. According to Dr. Olson this explanation “is not too far from the truth!”greglab (1)

Every job has its highlights and for Dr. Olson “field sampling is my favorite part of the job. I love being out on the water all day, cannot beat fresh air and sunshine!”. It is this part of the job for many field scientists. The part that gets them through the days when they have to process samples inside. Dr. Olson agrees saying “my least favorite part of the job is sample analysis, strictly speaking. It is fun when discovering something new or interesting but over time the process can get mundane. Integrating the same 75 odd compounds per sample for batches of 30, 50, or 100 samples can get tiresome.” All scientists agree that even though proces
sing samples can get tedious it is always exciting to realize that you have found something interesting.

Science is often a fine balance of planning and adapting to situations. This means that field science has a level of unpredictability that leads to some pretty interesting stories. For Dr. Olson recalls a time when “…I was out with another research assistant going to collect samples. It wasn’t until after we put the boat in the water that we realized we forgot to replace the drain plug! We scrambled to get it in place as our boat was taking on water. Luckily we were able to do so rather quickly and the boat was no worse for wear.”

It is always important for us to appreciate all of our hardworking scientists at the Coastal Waters Consortium! Dr. Gregory Olson is only one example of the great people that we have working on the questions of oil in the Gulf of Mexico.

The Myth of Science – – written by Leandra Darden

If you ask students what a scientist does, they will tell you, it is someone who does experiments. If you then ask them how many experiments they are running at a time, they will generally tell you one. Most of the time students are picturing someone in a lab with a lab coat mixing chemicals, and shouting “EUREKA” when they come up with the answer to their question. Cartoons have conditioned kids to believe that science is done inside with chemicals, and beakers, and an assistant named Igor. We are here to debunk some of the myths.

Myth 1: Science is done inside.


That is not true at all. Did Charles Darwin study animals inside? Did Galileo study the stars inside? The answer is no. To understand the natural world, you have to conduct science outside in the heat, cold, with bugs, wind, and sometimes rain. Nature is a beautiful interconnected world, and you have to preform experiments in situ. This means in the actual environment to begin to comprehend the intricacies of patterns. That is why scientists will set up experiments outside. Scientists will build study sites, generally near each other so they experience similar situations during the study time, which will include at least one treatment and a control. Then they have to check progress to collect data. This can mean daily, weekly, monthly or yearly trips out to the study site. While this often the best way to understand exactly what is going on, it can be time consuming, costly, and sometimes hard to understand what factor might be influencing the focus of the experiment. To try and alleviate some of the parameters scientists will build mesocasms, small versions of the environment that they can manipulate to get better results. This allows the scientist to fine tune any differences between treatments and begin to understand how they are affecting the results.

Myth 2: Scientists run one experiment at a time.

When you talk to various scientists they will tell you that one of the reasons that they chose the profession is because they had a lot of questions. After you run an experiment, you will begin to see more questions actually arise from your experiments than those you answer. Scientists will have many different projects running that may overlap but are seeking to find different answers.

Myth 3: Scientists work alone or with one assistant.

While in college many people would tell me that they wanted to be a scientist because they would not have to deal with people. The reality is that scientists are NOT loners, they are in fact, team oriented. In order to answer the many questions, process the massive amounts of data and samples, and just plain keep things in order a scientist will be a part of a lab. This lab generally includes research assistants, a lab manager, undergraduate students, graduate students, and post-docs all working together and on separate projects. Are there days where you are so caught up in your job that you may not see anyone, yes, but for the most part you are going to be part of a well-oiled machine that helps to identify and answer life’s questions.

Myth 4: All scientists wear a lab coat.


This is true and not true. Most scientists do not wear a lab coat all the time and some do not wear one at all. Even in more biologically focused labs, chemicals may be necessary to process samples. A lab coat is not for show, it is to protect yourself and your clothing from anything harmful. A lot of the equipment being used needs to be kept at low temperatures so the lab coat has the added bonus of keeping you warm!

Myth 5: Scientists yell “Eureka” when they make a discovery.

It is fun to think that all scientists have that lightbulb moment and they remember to yell that iconic phrase…but the reality is not so. During a discovery you are more likely to hear a “FINALLY” or a “Hmmm, this is weird” or “I don’t understand what is happening” than anything else.


Hopefully we have successfully refuted some of the myths behind science!

New CWC Family Event: Life Along the Edge

Join CWC scientists and educators for a day of learning and exploring our coastal marshes.  Attendees will learn how CWC scientists are measuring the health of the marsh using common salt marsh fishes.

The event will be held on May 31st from 9am-3pm at the DeFelice Marine Center in Cocodrie, LA.  Registration is required.  Students must be 12  years old or older to participate.

Workshop Highlights:  Kayak trip through the salt marsh, presentations and activities led by CWC scientists and educators.
