Brett D. Jameson, PhD
Marine Microbiologist | Molecular Ecologist
Welcome to the page!
My name is Brett and I am a Postdoctoral Scientist at the Bermuda Institute of Ocean Sciences (BIOS). My research is broadly concerned with the relationships between biological diversity and ecosystem function in marine environments, and the response of ecological communities to environmental change. My current work with the Coral Reef Biology team at BIOS aims to identify molecular, cellular, and physiological markers of coral resilience in the context of a changing climate.
My goal is to make this webpage both a catalogue of my adventures in marine science moving forward, and a repository for my thoughts on a wide range of related and unrelated topics.
The site is in progress at the moment but I will be adding more content shortly.

Thanks for stopping by!
As you were.

Microbial keystones modulate water column N2O cycling
Network analysis of 16S rRNA-sequencing data collected over six months in the Saanich Inlet on Vancouver Island, Canada, suggests keystone microbial taxa might contribute to water column N2O production and accumulation. This work presents important insights into the potential role of ecological interactions, mediated through keystone taxa, in driving ecosystem function.

Continental margin sediments are an N2O source
We present an improved method of constraining N2O production and vertical fluxes in deep-water sediments using trace-level microsensors and mathematical modelling. We demonstrate that continental margin sediments underlying the NE Pacific oxygen minimum zone are a significant source of N2O to the overlying water column, and that low-oxygen events such as upwelling can stimulate N2O production in outer shelf sediments.
