Marine #microorganisms are crucial for #ocean health.

#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.

They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.

Ocean modelling must evolve to take their biological complexity into account.

‘Oceans are hugely complex’: modelling marine microbes is key to climate forecasts

Microorganisms are the engines that drive most marine processes. Ocean modelling must evolve to take their biological complexity into account.

I'm in Appledore in Devon, to give a talk later about Blue Machine and I've just discovered that they have a KNITTED OCEAN outside their church. And this is the Best Thing Ever.

Phylogenetic diversity and functional potential of large and cell-associated viruses in the Bay of Bengal

The Bay of Bengal (BoB), the largest bay in the world, provides valuable ecosystem services such as fishing and recreation to millions of people living along its coast and has a significant economic value.

Happy to share a collaborative preprint with Assaf Vardi's group in which we use single cell transcriptomics to link giant viruses with their native hosts during a marine algal bloom!

This approach is quite sensitive - we were able to identify viruses infecting one protist group that made up <0.5% of the community.

Homing in on the rare virosphere reveals the native host of giant viruses

Giant viruses (phylum Nucleocytoviricota) are globally distributed in aquatic ecosystems They play major roles as evolutionary drivers of eukaryotic plankton and regulators of global biogeochemical cycles.

My first "reviewed preprint" on @eLife !

A Timeline of Bacterial and Archaeal Diversification in the Ocean

Lots of hard work from former PhD student in my lab Carolina Martinez. Part of a collaboration with @pseudacris

We are enjoying the new process so far and working on revisions to address some of the concerns raised by reviewers.

Wonderful essay by @vincentflora and Assaf Vardi on viruses in the ocean

Viral infection in the ocean—A journey across scales

"Aquatic virology tackles some of the most challenging questions in microbial ecology and oceanography, trying to understand how microorganisms that are invisible to the naked eye can influence large-scale processes, such as biogeochemical cycles, or affect entire marine food webs."

Viral infection in the ocean—A journey across scales

Viruses are the most abundant biological entity in the ocean. This Essay journeys across several orders of magnitude of biological organization, time, and space, to investigate interactions between hosts and viruses in the ocean and their relevance f…
