Ending the first Diel sampling set


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.

Diel Sampling: Update

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.

Waiting for the first CTD cast…also a snap of Lauren Gillies thinking hard about what what their game plan is

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.

The sampling set up…woo! Make sure you secure your Yeti things.

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.

Look to the left of the oil rig and there is a line from the water to the clouds. That is the water spout! Thank again to Mary Kate Rogener for the photo. 

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!

Diel sampling: Cruise number two with the LUMCON team

Today, we board the RV Pelican for a second time in two weeks. The Thrash lab will be sampling with Mary Kate Rogener (@mkrogener) from Dr. Samantha Joye’s lab (UGA), Post Doc Ari Chelsky (Brian Roberts, LUMCON), Lauren Gillies and Erin (@GilliesLE) from Dr. Olivia Mason (FSU), and Wokil Bam from Dr. R. Eugene Turner‘s lab (LSU) under the lead of Dr. Nancy Rabalais (LUMCON).

Unlike the NGOM Shelfwide Hypxoia cruise, we will be focusing this cruise on two sampling sites within the Hypoxia transect over 24 hours.

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).

Northern Gulf of Mexico Shelfwide Hypoxia Cruise

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.

Once again, our lab was working with Dr. Olivia Mason from Florida State University and her graduate student Lauren Gillies (@GilliesLE), who recently published a paper with Dr. Thrash from the 2013 research cruise: Archaeal enrichment in the hypoxic zone in the northern Gulf of Mexico. Congrats to them!

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.

Our set up with the clean hood added for me to culture!

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.

Sometimes when you filter three depths in the Hypoxic waters you get three colors.
