Mike and I went on a sampling trip Tuesday (1/12/16) to the Mississippi Delta (“The Birdfoot”) near Buras, LA. This was my first sampling trip ever with the Thrash lab, and I must say that it was a great experience! We headed out loaded up with our equipment and coffee, and ended up with a fantastic view of the sunrise at the edge of Lake Pontchartrain. Sadly, the picture does not come close to the beauty of our actual view.
At the site, Mike waded out into the water to collect the sample while I got to hang back and enjoy the scenery. It was a great day to be outdoors with cool air and the sun shining.
Overall, I really enjoyed my sampling adventure with Mike. This trip was a part of our 3 year study of the coastline to characterize the microbial population of the Louisiana coast in conjunction with adding microbes to our Louisiana State culture collection (LSUCC) from the Gulf of Mexico. I’m hopeful that we will isolate some novel organisms from this and future trips. Not all undergraduates are lucky enough to be a part of a lab that allows us to be out in the field for data collection, so I’m grateful to Dr. Thrash and Mike for the opportunity!
Enjoy some time pictures from time points 0200 and 0600 as we completed our 24 hour survey at the C transect site. The video I have uploaded is of the Platform and its fog horn that sounds every 20 seconds or so. Its a real joy to work and sleep to.
Well Day 1 has come and starting to end though my day will still go on for another 10-12 hours. When I woke up this AM, the ship was tossing and rolling quiet a bit for being in the Gulf. The first time point was at 0600 and between lack of sleep, an early morning, and some good waves, I wasn’t exactly feeling bright eyed and bushy tailed, nor was anyone else. Alas, the day went on and the time points began to come and go.
The first and second time points were split up by a trip just past the site C6B where Dr. Nancy Rabalais (LUMCON) and Dr. Brian Roberts (LUMCON) took sediment cores for experiments they wanted to run back at LUMCON.
The second time point was quiet, it was just me sampling so I had the whole CTD to myself. But of course the day isn’t complete without some type of problem ! HA! I am three for three on cruises that have some sort of issue, but some say thats oceanography. Anyways, thanks to the awesome crew of the RV Pelican, and some patience, we got the hydraulics fixed and were able to once again deploy the CTD.
While on the water, you get to see a lot of things : dolphins, fish, jelly fish, etc. But today, between time point three and four, I got to see a Water Spout which I was really excited about. It was pretty far away and the only picture we got is thanks to Mary Kate.
Overall, all is going well. I am waiting for time point 5 to come (2200) and then hopefully get a nap in before time point 6 (0200). Follow my twitter account (@Hensonmw_08) for more live updates. Enjoy some pictures!
Sampling will once again include three depths, while collecting water for nutrient data and filters for microbial community data. The idea will be similar to our Fronts sampling.
Others on the cruise will be working on sediment cores (I am excited for this!) as well as work on biogeochemistry rates.
Follow along as we go on our five day journey! And don’t be afraid to ask some questions! And Make sure to follow me on Twitter for live updates (@Hensonmw_08) as well as Mary Kate (@mkrogener) and Lauren (@GilliesLE).
Two weeks ago, I was able to take part in the 6 day Northern Gulf of Mexico research cruise. This is its 31st year that it is going on and our third year taking part in it (see 1, 2). This year I was the lucky one to go instead of Dr. Thrash. This was my first official collection cruise so I was pretty excited to finally get out on a boat and put into practice everything I had learned while at the CMORE summer course.
Though for the most part the set up and collection was the same as past years, this year I added a little twist to the game: Culturing.
The cruise was a lot of fun and as usual I learned a ton about the Northern Gulf of Mexico and hypoxia. The main focus of the rest of the cruise was determining the size and nature of the 2015 “dead zone”. Dr. Rabalais (LUMCON) and her team worked countless hours to make sure all the data was collected and ready to be sent to NOAA, the EPA, and the public. This year we found that the dead zone was larger then scientists had predicted. This year’s dead zone extended over more than 6,400 square miles.
A few more pictures of me with some of the awesome graduate researchers (Mary Kate Rogener (@mkrogener) from Dr. Samantha Joye’s lab (UGA)) and Post Doc Ari Chelsky (Brian Roberts, LUMCON) also on board the RV Pelican.
Keep an eye out for more publications from the Mason and Thrash groups on this exciting research area!
Okay, first off, sorry for all these late posts. This summer has been pretty crazy for all of the Thrash lab! We have been busy with sampling, trips, etc…safe to say, we have generated plenty of data this summer.
This summer I was able to take part in the 2015 CMORE Summer Course on Microbial Oceanography. The course is roughly a five week long intensive learning environment hosted by the Center for Microbial Oceanography: Research and Education at The University of Hawaii Moana in Honolulu, Hawaii. In total, 16 students from around the world (Germany, Austria, Israel, Spain to name a few) were invited through an application process to attend the course titled ” Microbial Oceanography: Genomes to Biomes”.
After some awesome introductions the first day by Dr. Dave Karl, Dr. Matt Church, and Dr. Ed DeLong, we started our first week of lectures from our main speakers Dr. Angelicque White, Dr. Mick Follows, and Dr. Dan Repeta. The topics covered nutrient cycling to modeling and focused more on describing the ocean as a habitat. For me, it was my first time really tackling this type of information and it was a lot of information to take in. But lucky for me, we had some of the best teachers there to help us through it all.
Even though the group came from a diverse background, we all felt a strong bond with each other.
The RV Kilo Moana was an amazing ship and quite big. Especially if this was your first time being on a research cruise or a research vessel. I guess, I was a bit spoiled.
The cruise was one of the things I was most excited about. And to be honest, it was amazing. The CMORE crew did an amazing job prepping the ship and materials for us to use. During the cruise, we had five groups that rotated through five “stations”. The “stations” were flow cytometry (counts and sorting), molecular (DNA extractions, PCR, Sequencing Prep), physical oceanography (CTD prep, casting, retrieval ,etc), productivity (PP and BP), and nutrient analysis (Chlorophyll, ATP, Nutrients). Each day gave us a new station to work at and the ability to learn new techniques. To be short, for those familiar with the Hawaiian Ocean Time Series (HOTS), this is the type of data we collected. The data we collected and analyzed as well as protocols can be found on the CMORE website. The cruise was hard work and I found myself learning something new every time we did a station. We even learned what happens when an array gets too close to the boat 🙂 .
It is hard to put into words how much I learned on this trip, how many new friends and colleagues I gained, and the amount I grew as a scientist. I cannot thank all the individuals that put this on, participated in, and helped out with this course enough.
Enjoy a little closing video I made for the group and everyone after we presented our data at a seminar for all SOEST and CMORE.
