New Publication Alert! Study revealing deep-sea shipwrecks represent island-like ecosystems for marine microbiomes published in The ISME Journal

In April, we published a research article in The ISME Journal titled “Deep-sea shipwrecks represent island-like ecosystems for marine microbiomes”. The paper, by Dr. Leila Hamdan and colleagues, investigated the influence a deep-sea shipwreck, Anona, exerts on sediment microbiomes in the deep sea.

Biogeography of macro- and micro-organisms in the deep sea is, in part, shaped by naturally occurring heterogeneous habitat features of geological and biological origin such as seeps, vents, seamounts, whale and wood-falls. Artificial features including shipwrecks and energy infrastructure shape the biogeographic patterns of macro-organisms; how they influence microorganisms is unclear. Shipwrecks may function as islands of biodiversity for microbiomes, creating a patchwork of habitats with influence radiating out into the seabed. Here we show microbiome richness and diversity increase as a function of proximity to the historic deep-sea shipwreck, Anona, in the Gulf of Mexico. Diversity and richness extinction plots provide evidence of an island effect on microbiomes. A halo of core taxa on the seabed was observed up to 200 m away from the wreck indicative of the transition zone from shipwreck habitat to the surrounding environment. Transition zones around natural habitat features are often small in area compared to what was observed at Anona, indicating shipwrecks may exert a large sphere of influence on seabed microbiomes. Historic shipwrecks are abundant, isolated habitats with global distribution, providing a means to explore contemporary processes shaping biogeography on the seafloor. This work is a case study for how built environments impact microbial biodiversity and provides new information on how arrival of material to the seafloor shapes benthic microbiomes.

A Thesis & A Thank You

I recently defended my Master’s Thesis “How Historic Shipwrecks Influence Dispersal of Deep-sea Microbiomes”. My thesis investigated how historic (> 50 years old) wooden shipwrecks influence dispersal of deep-sea microbiomes by placing introduced wood on the seafloor in near proximity (0-200 m) to wooden-hulled historic shipwrecks in the northern Gulf of Mexico (GoM). Biofilms formed on experiments were analyzed for microbiome richness, diversity, and phylogenetic composition. Richness and diversity decreased with decreasing proximity to both shipwrecks revealing historic shipwrecks may function as island-like habitats. The phylogenetic composition analysis shows strong selection by wood type for bacteria, and highlights differences in bacteria, archaea, and fungi dispersal patterns. The results of my thesis show that built structures, like shipwrecks, impact microbial biogeography in the deep sea. I will be working through the summer to publish this research.

Conducting this research was challenging, but extremely exciting. I am grateful to all the people who assisted me and helped make this thesis and my defense a success. I could not have done it without my advisor and lab mates standing with me (even through 8-foot seas on the recovery cruise for my experiments). I could not have done it without our collaborators and those who helped on the research cruises aboard USM’s R/V Point Sur. I could also not have done it without the support of my family. Thank you all. I have thoroughly enjoyed my time as a graduate student in the Hamdan Lab and at USM. #SMTTDeep

Hamdan Lab in New York Times

We are very excited to share that our research on shipwreck microbiomes was recently featured in the New York Times! Article “Microbes Point the Way to Shipwrecks” by Katherine Kornei was published in February 2020 and highlights our newest findings from two studies presented at the Ocean Sciences Meeting 2020 in San Diego. Check out the article to find out more about steel yacht Anona, the two wooden shipwrecks we explored last summer, and their microbiomes!

This week, the National Science Foundation (NSF) announced it selected the Gulf – Caribbean Oceanographic Consortium, cooperatively led by The University of Southern Mississippi (USM) and the Louisiana Universities Marine Consortium (LUMCON), to operate the third new oceanographic research ship to carry out regional scale research in the Gulf of Mexico, Caribbean Sea and Atlantic Ocean. We are thrilled by this announcement and this opportunity to support, enhance and expand scientific research and discovery in the Gulf and Caribbean.

Our lab had a unique insight in the process that lead to this award. I worked with a team at USM and LUMCON to develop the proposal and a vision for supporting ocean science through the use of this ship. I also had the chance to see my lab team pull together. The lab endured the development of this proposal over several months. They heard the conference calls, the “ding” of hundreds of emails, and bore witness to a horrendous stress diet (candy? did someone say candy?). Worst of all, proposal submission converged with our prep for the Microbial Stowaways cruise, leading to this very accurate Venn diagram:

Through it all, we stuck together, supported each other, and made our work matter, for our research and in support of the academic research fleet. I was honored to work on this proposal, and excited about the work ahead with UNOLS. I am overflowing with gratitude for how our lab members stuck together, worked hard, and supported this important award.

Rachel, Rachel, Anirban, Justyna and Leif, I am glad we made it through July/August. I am glad we are a team.

Microbial Stowaways Research Expedition

On June 25th, 2019, we will embark on the first research cruise for the Microbial Stowaways project, funded by NOAA’s Ocean Exploration and Research program. This expedition will take 9 days aboard USMs R/V Point Sur with ROV Odysseus on board. Our team includes 8 scientist, 2 archeologist, 4 ROV crew members, an outreach specialist, a middle-school teacher from the NOAA Teacher at Sea program, and 8 Point Sur crew members.

35224223382_e06ecf6a25_z

Main goals for this expedition are to discover and characterize two unexplored, wooden shipwrecks in the Gulf of Mexico, and investigate their role in microbial biogeography in the deep-sea. We will be collecting hours of video footage of these never before seen shipwrecks, and collecting sediment and water samples around them to explore the environment and microbiomes around these exciting habitats. We will also deploy experiments on the seafloor to study how biofilms form on surfaces in the deep-sea, a critical step which takes shipwrecks out maritime past and into the present as artificial reef ecosystems, teaming with life both visible, and invisible.

Our lab is in the middle of cruise preparations, a busy but exciting time! We are planning the cruise track, dive plan, and sampling schedule. And, importantly, taping and labeling vials for sample collection by the 100s. These expeditions depend on attention to detail, early preparation, and a lot of supplies.

On June 24th – 25th, we will be at Port of Gulfport, in Gulfport, MS doing our cruise mobilization and engaging with the Ocean Science and Technology Sea Camp students who will be visiting the ship with staff from USMs Marine Education Center. As a part of the Camp, high school students will tour R/V Point Sur. observe our preparations to go offshore and talk with us during a live telepresence event later in the week.

We will set sail by midnight on June 25th. Stay tuned for pictures and videos! Follow @HamdanLab and @Just_AquaticN on Twitter for cruise updates. SMTTDeep!

Seeking Graduate Student for Oyster Aquaculture Microbiome Study

We seek an exceptional student to participate in microbial ecological research concerning marine aquaculture. In the Gulf of Mexico there is considerable interest in developing technologies to expand the oyster industry through aquaculture. The chemical and microbiological conditions which permit survival of healthy oyster larvae and ultimately production of viable oysters are largely unknown. We invite students interested in studying the intersection of ecology and oyster aquaculture to apply for a Graduate Research Assistantship in the Division of Coastal Sciences at the University of Southern Mississippi to explore aquaculture microbiomes.

Successful applicants will have a BS or MS degree in biology, ecology, environmental science, chemistry, aquaculture or relevant field. Applicants with experience in molecular biology, biogeochemistry, larval culture or statistical analysis are encouraged to apply. Students are expected to develop manuscripts for peer review, participate in outreach, and present results in written and oral formats. This opportunity will involve collaboration with experts in marine aquaculture at the Thad Cochran Marine Aquaculture Center and provide a rich environment for learning about marine microbial ecology.

Individuals that are serious about graduate study should contact Dr. Leila Hamdan (leila.hamdan@usm.edu). Please provide a cover letter outlining specific interests and experience in the study of microbial ecology or marine aquaculture and a curriculum vita. Application for Fall  2019 admission at USM is required.

2018 in Photos

Towards the end of 2018, the lab became very busy developing and implementing a new study supported by the Defense Advanced Research Projects Agency’s (DARPA) Biological Technology Office. The goal of this work is to use microbiomes to tell us about the history and present of human structures on the seafloor. The project came up fast, and in August and September, all hands in the Hamdan Lab, some extra hands from the School of Ocean Science and Engineering, and some more hands from our collaborators at the MMRI at University of Mississippi worked together to design, build and test seafloor landers and experimental arrays to collect biofilms. We benefited from the support and advice of the crew of R/V Point Sur (University of Southern Mississippi’s ship), and worked closely with ocean engineers who helped us integrate our experiments with the remotely operated vehicle Odysseus (Pelagic Research Systems, Inc), which ultimately drove our experiments to depths up to 2000m deep, and placed them exactly where they needed to be to accomplish our goals. Then, in December, we went back out in the Gulf of Mexico on R/V Point Sur, and called all eight of our experiments home.

This work was incredibly hands on, extremely tiring, and required all of our imagination and “make it work” skills. It was also a huge amount of fun. You can see it on our faces in the photo albums posted below. These are long overdue, and we hope you enjoy seeing the many perspectives of marine microbial ecology and ocean engineering happening here, and appreciate the happy, smiling, science we accomplished together.
