July 31, 2019–Meet the scientists!

When swapping at-sea stories with colleagues, we can all agree that who you share the boat with will easily make or break a research cruise. As a consortium project, there are 18 scientists representing four institutions on board the R/V Point Sur, all with different skill sets, levels of experience, and paths that brought them to the CONCORDE team. While it may seem a bit crowded for one boat, we all brag about how well everyone gets along. Not only has everyone shown great interest in each other’s projects, there has also been a lot of scientific discussion, shared information, and talk of future collaborations, especially among the early career scientists aboard the ship. When remembering that the term “Concordia” is Latin for harmony, this project could not have been more appropriately named. We feel very proud to be part of such a great consortium and are so excited to see the future careers of everyone coming from the CONCORDE team!

Scientists 1 Briseno-Avena


Dr. Christian Briseño-Avena – Hatfield Marine Science Center at Oregon State University – Christian, a post doc from OSU, is the Chief Scientist for the Summer CONCORDE cruise and has been excellent at coordinating research activities. He also operates the In Situ Ichthyoplankton Imaging System (ISIIS) to examine zooplankton distributions within the water column with fellow post-doc Dr. Adam Greer. Christian has been on many research cruises including one across the Equator where his Polywog name was “Stupid Penguin.”




Scientists 11 Martin


Kevin Martin – Division of Marine Science at University of Southern Mississippi –the Field Operations Coordinator for the CONCORDE project, sometimes referred to as the equipment extraordinaire and logistics guru, Kevin served as co-Chief Scientist on this cruise. Kevin operates the CTD, POGO, and is always on standby when needed for the mininess and ISIIS. We really aren’t sure where we would be without Kevin on board! Kevin has spent many days at sea or traveling to remote locations for research. He has even taken a submersible 900 m down in the Gulf of Mexico and been bitten by a penguin in Antarctica.




Scientists 2 Weidemann

Dr. Alan Weidemann – Naval Research Lab – Alan is the principal investigator on board. We have thoroughly enjoyed his mentoring and guidance while on the R/V Point Sur. He has shown extreme interest in each person’s research and has been a great pleasure to work with sharing his life and career experiences throughout the whole cruise. If you ever get a chance to sit down and chat with him, ask him about the Royal Society of the Killer Daphnia!



Scientists 3 Deary


Dr. Alison Deary – Division of Coastal Sciences at University of Southern Mississippi – Ali is a post-doc under Dr. Frank Hernandez at the Gulf Coast Research Lab at USM. She served as Chief Scientist during the Spring CONCORDE cruise. Currently, she is mentoring master’s student, Angie Hoover, to look at larval fish condition throughout the northern Gulf of Mexico. Ali is not new to research cruises. In fact, she has done research in both hemispheres and is known for wearing her lucky corgi socks aboard the ship while managing plankton sampling operations.





Scientists 4 Greer


Dr. Adam Greer – Division of Marine Science at University of Southern Mississippi – Adam is a post-doc under Dr. Monty Graham at USM and contributes to the CONCORDE mission by managing operations of the ISIIS.

July 29, 2018–Hypoxia blog
During the process studies for the Fall and Spring cruises, we were interested in sampling stratification and freshwater plumes, respectively. We decided to change gears for our Summer campaign and for our current process study, we are looking to sample low oxygen areas, more commonly known as hypoxia. The northern Gulf of Mexico is infamous as the second largest hypoxic region worldwide with the areal extent of hypoxia sometimes being about the size of Massachusetts! For us at CONCORDE, we are interested in examining hypoxia during our process study because it can change the distribution of plankton in the water column. Some depths, especially near the bottom, do not contain enough dissolved oxygen to support many creatures. In addition, the extent of the hypoxic conditions can be influenced by the amount of freshwater added to our system, nutrients, and stratification. Aboard the R/V Point Sur, each of our research teams has ways to measure the oxygen in the water ranging from sensors mounted on our sampling gear to Winkler titrations in the wet lab. With today’s blog, we want to highlight the different methods we us to look at hypoxia during our CONCORDE cruises.

The CTD Rosette, MININESS, and ISIIS are all equipped with dissolved oxygen sensors similar to this one, which is attached to the top of our MININESS net system. Sensor provided by Center for Fisheries Research and Development, USM.
Allie Mojzis measures dissolved oxygen in water samples collected from the rosette using a method called a Winkler titration. Pictured here are two flasks that she has already analyzed from two different depths. D4 (left) was taken from the surface and has an oxygen concentration about 6 mg/L, whereas D11 (right) was collected near the bottom and is hypoxic with a concentration around 2 mg/L. Note that D4 has a darker color than D11 and this color difference helps us interpret these results.
For the process study, we are targeting small depth intervals through the water column. To do this, we slowly lower it deeper into the water until we get near the bottom and then we slowly bring it back through the water column until we retrieve it. Therefore, our tow profiles have steps where we maintain a depth but you can see as our MININESS dives deeper in the water column that we are fishing our nets above and below hypoxia over time. In our plot from 0200 on July 28th, 2016, the horizontal axis is time in second, denoted by “Scan,” the vertical access is depth below the surface in meters, and oxygen (mg/L) is represented by the color bar.
The rosette is also equipped with a dissolved oxygen sensor in addition to a lot of other sensors that characterize the water column for us. This rosette plot, taken on July 28th, 2016 near the location of the net samples, shows that the dissolved oxygen (purple line) below 12.5 meters deep is less than 2 mg/L, meaning it is hypoxic. Other parameters graphed here are fluorescence (green), salinity (red), and temperature (blue).
Unlike the MININESS, which we step through the water column during a single tow, ISIIS undulates up and down through the water column during its transect, giving us a good idea of the DO levels from surface to near-bottom in this colorful plot. The bottom axis is latitude (north to the right) and the vertical axis is depth below the surface in meters. The colors depict the measured oxygen with warmer colors representing higher oxygen concentrations and cooler colors representing lower oxygen concentrations. From this plot, we can see that the water from about 14 m to near the bottom are hypoxic until the area north of 29.84°N, where the oxygen levels increase. Plot provided by ISIIS, AT Greer.
To help guide our sampling, Christian has been posting the dissolved oxygen plots from our different sampling event to one of the doors in the lab so we can use it as a reference as we sample.
































July 28, 2016–Crazy Critters!

When the average person discovers that we are marine biologists, they typically assume that we study dolphins, whales, or large pelagic fish such as sharks. But for us CONCORDE biologists, the tiny critters that drift and float passively through the seawater are our charismatic creatures. While seemingly insignificant to most, these microscopic organisms, collectively termed “plankton,” are the base of the food chain and a critical source of nutrients for many larger aquatic lifeforms, such as the aforementioned fishes and whales. Plankton is made up of bacteria, algae, crustaceans, fish larvae, fish and invertebrate eggs, worms and so much more that pique our curiosity as researchers on board the R/V Point Sur. The CONCORDE biological division consists of graduate student Adam Boyette, who uses a FlowCAM to image phytoplankton; Dr. Adam Greer and Dr. Christian Briseño-Avena, who use the In Situ Ichthyoplankton Imaging System (ISIIS) to image zooplankton; and Dr. Ali Deary, Carla Culpepper, Sarah Muffelman, Kelia Axler, and Antonio Pliru, who use plankton nets to sample for larval fish and zooplankton and a microscope camera to photograph interesting critters. See below for a selection of images taken by the biological team’s FlowCAM, ISIIS, and microscope camera during the CONCORDE cruises.

July 27, 2016–Point Sur Cuisine

One thing people might not realize about research vessels is how well fed we are while on board. Research on a boat can be very labor intensive and sitting down to a good meal can easily be the highlight after a long day of sampling. Here aboard the R/V Point Sur, Chef Alex Forsythe prides himself on preparing the traditional favorites while always creating a well-balanced healthy meal. He goes above and beyond to provide beverage and entrée options, but requests are always encouraged. No cruise is complete until we have had at least one Taco Tuesday. Some other favorites amongst the scientists are gourmet s’mores, hamburgers, steak, and tiramisu. He also makes a mean biscuit and gravy and there seems to be a never-ending supply of bacon. Full, happy scientists make for a full, happy cruise!

July 26, 2016–Meet the Crew of the “Point Sure”

Since the beginning of the CONCORDE project, a few of us researchers have begun fondly referring to the R/V Point Sur as the “good ol’ Point Sure,” because it became immediately obvious that the crew would do anything they could to help the scientists. The crew has come from a variety of different backgrounds with decades of collective time spent aboard commercial and research vessels. From the Gulf of Mexico oil fields to the Alaskan fisheries, the crew has a wide range of experience to contribute to running a successful, safe, and happy ship.

Crew 1 Allen
Captain Nicholas Allen has been overseeing operations of the R/V Point Sur since its relocation from Moss Landing in early 2015. He has degrees in marine biology from East Carolina University and marine technology from Cape Fear Community College and has worked on a variety of vessels ranging from small river tour boats to large research vessels. Captain Nic enjoys supporting science and the different challenges that working with each research group offers.
Crew 2 Acker
Chief Mate/Assistant Engineer Ben Acker began his maritime career as a deckhand and has worked a variety of roles onboard, including Assistant Engineer, eventually working his way up to Chief Mate this year. He enjoys helping with the CONCORDE project because of the variety of interesting research happening onboard. Fun fact: Prior to joining the crew of the R/V Point Sur, Ben worked as a scuba diving instructor in the Florida Keys.
Crew 3 Jansen
Chief Engineer Joshua Jansen was raised in a naval family and grew to love working on the water. He started as an ordinary seaman on a research vessel in the Gulf of Mexico, but has traveled to many places by boat including Alaska, Tahiti, and Trinidad. He spent some time in the oil fields gaining more knowledge and experience, which has culminated in him becoming Chief Engineer on the R/V Point Sur.



Marine Technician Marshall Kormanec received a B.S. in Biology at University of North Carolina Wilmington, spent some time as a fisheries observer in Alaska, and returned to academia to receive his Master’s in Oceanography from Louisiana State University. After receiving his M.S., he began looking for a job that wasn’t a typical “9-to-5” in order to allow the time and flexibility to travel the world. He ultimately found the right fit and secured a spot as a deckhand on the R/V Point Sur, where he quickly rose to Marine Technician.
Chef Alex Forsythe has been providing delicious meals on LUMCON research vessels for over ten years. Chef Alex enjoys the challenge of cooking healthy alternatives, which are often rare on vessels, and his culinary creations were recognized when he received an award for best food in the University-National Oceanographic Laboratory System (UNOLS) fleet.


Crew 6 Rath
Mate Jack Rath is originally from California but now resides in Daphne, AL. He spent twelve years in the Marines before he started working as a deckhand in the oil fields around six years ago and has now risen to mate on the R/V Point Sur. He enjoys the youthfulness of working on a research vessel and feels like he is continually learning.
Crew 7 Beirbaum
Deckhand Josh Bierbaum received a B.S. from Western Illinois University in 2015. He joined the R/V Point Sur crew as a deckhand with his maiden voyage being the spring CONCORDE cruise. We have gotten to watch him learn and progress within vessel operations and he has become a favorite amongst the night crew.











































July 25, 2016–Equipment and Instrumentation

July 23-24, 2016–Let the sampling commence!

A Day in the Life of a CONCORDEian Onboard the R/V Point Sur

After nearly 48 hours of preparation, mobilization, and calibration, we’re finally here to do what we came to do! We completed the multibeam patch test in time to reach our first station, situated just east of the Chandeleur Islands. The night crew hit the deck at 7:30 pm with enthusiasm and collected water from eight different stations throughout the night, using a variety of sampling equipment. In addition to using a variety of gear, the water team looked at both the chemical composition and phytoplankton, which are microscopic marine plants, throughout the water column at each station. The following morning, the plankton team deployed their nets just after sunrise in an effort to support our plankton imaging system (ISIIS), which is towed for six hours during the day centered around local noon. The ISIIS is pulled through the water column behind the R/V Point Sur at five knots, continuously collecting images of Gulf of Mexico microscopic life. Simultaneously, the multibeam team used acoustic signals to continuously map the seafloor in order to inform the CONCORDE researchers of the changing bottom topography during sampling efforts. Not long before sunset, the plankton team cast their nets back overboard to collect the last set of daytime samples, just in time to give way to the water team as they returned to deck for night sampling.

July 22, 2016–Mobilizing for Research

Mobilization, or as we like to call it “mob,” is the staging of the vessel for a scientific cruise. This involves packing any equipment that could potentially be used for collection of samples, experiments, or data processing and transporting it to the ship. This requires a lot of planning and forethought, as once we are at sea, we cannot simply go to the store. Once at the port, the ship and science crew work through rain or shine to set up the vessel for research, which entails cranes, hardhats, and teamwork!

Trucks and trailers are used to transport our state-of-the-art equipment from the lab to the port.
Once at the port, the ship’s crew helps in craning heavy equipment onto the R/V Point Sur.
Science team members, Lanora Vasquez del Mercado and Kelia Axler carry a tote of scientific equipment on the boat using the gangplank.
