Underwater Scuba Diver

Underwater cameras capture diel vertical migration of microbes in the mat world: Microbial mats composed of photosynthetic cyanobacteria (purple patches) and chemosynthetic microbes (white patches) in the sulfidic low-oxygen waters of Middle Island Sinkhole in Lake Huron (23 m depth) take turns at the mat surface during day and night, respectively. Motile mats like these on the Precambrian seafloor may have laid the foundation for the modern biosphere by optimizing photosynthesis, chemosynthesis, organic carbon burial and oxygen export (Diver photo credit: Phil Hartmeyer, NOAA Thunder Bay National Marine Sanctuary).

"TANGO IN THE MAT WORLD" PROJECT RECEIVES NSF SUPPORT

Bopi Biddanda, Sarah Hamsher, and Anthony Weinke at AWRI, along with their colleague Dale Casamatta at University of North Florida (UNF), have received a $280,000 ($190,000 to GVSU and $90,000 to UNF) collaborative research grant from NSF’s Biological Oceanography program for a project entitled, “Tango in the Mat World: Biogeochemistry of diurnal vertical migration in microbial mats of Lake Huron’s sinkholes”. This collaborative project will run through February 2023 and brings together researchers with expertise in biogeochemistry, algal/cyanobacterial biology and molecular ecology, and will provide outstanding research opportunities for undergraduate and graduate students.

Benthic microbial mats inhabiting Lake Huron’s low-oxygen, high-sulfur submerged sinkholes resemble life on early Earth. These mat worlds are dominated by motile filaments of cyanobacteria, bacteria, and motile diatoms. Recently, we have gathered visual evidence of their active diurnal vertical migration (DVM) in the field. Such a synchronized diurnal “tango” might have been the largest daily mass movement of life during the long Archean and Proterozoic eras, and played a critical role in optimizing photosynthesis, chemosynthesis, carbon burial, and oxygenation. This project will aim to unravel the who, why, and how of microbial DVM through integration of microscopy, cultures, molecular approaches, and process rate measurements in response to changing gradients of light, sulfide and oxygen.

By studying microbial communities that have regular and measurable circadian rhythms in processes that can also be tracked at molecular levels, we will achieve an unprecedented view of the molecular underpinnings of microbial mat biogeochemistry and lay the foundation for future studies aimed at re-defining the role of autotrophic communities in ancient seas and modern ecosystems.
