I've released Pythia, an open source web API/service for running #MachineLearning inference on images using #yolov5. The repo and instructions for running your own model are at https://github.com/mbari-org/pythia. We have a demo sever UI running on a small VM at http://fathomnet.org:7777 that can id #deepsea #benthic animals off the coast of California.

🚨🚨New Paper Alert🚨🚨

We have a new paper out in Earth & Planetary Science Letters (#EPSL) entitled “Indian margin methane hydrate dissociation recorded in the carbon isotopes of benthic (Miliolida) foraminifera”

Main take home message: we have identified a group of #benthic #foraminifera (unicellular organisms living at the bottom of the #ocean) whose shell chemistry carries signatures of #methane dynamics within #marine #sediments.

🚨🚨New Paper Alert🚨🚨

We (led by Steve Clemens, along with Davide Oppo) have a new paper out in Earth & Planetary Science Letters (#EPSL) entitled “Indian margin methane hydrate dissociation recorded in the carbon isotopes of benthic (Miliolida) foraminifera”

Main take home message: we have identified a group of #benthic #foraminifera (unicellular organisms living at the bottom of the #ocean) whose shell chemistry carries signatures of #methane dynamics within #marine #sediments.

#Benthic species, Latibolivina subreticulata as #TheOceans' #Precambrian #foraminifera

#Benthic #foraminifera Bulumina aculeata as #Autopsy's Macabre Eternal. #deathmetal #forams

#Benthic #foram Lagena sulcata as #IronMaiden's Seventh Son of a Seventh Son.

So today was spent testing our new #Benthic chamber lander for measuring #seabed #oxygen consumption. Love #oceanography field work.

Some lovely #oceanography field work today, testing out our new #unisense #Benthic chamber lander. Successfully deployed and recovered and we got some data too!

Next up in our Meet the Next Generation of Deep-Sea Researchers series is #HenryKnauber, PhD student at #Senckenberg, whose research focuses on how #depth, #distance and #barriers promote #speciation in small #DeepSea #benthic #isopods! https://tinyurl.com/29uax4cm

On our end, we've been using #benthic #macroinvertebrates , bugs collected from the bottom of #streams , as 'natural' #eDNA samplers. So far, we've been able to detect both #macroinvertebrates and #diatoms from the same mixed community samples to construct trophic networks to assess stability and identify keystone species "Multi-marker metabarcoding resolves subtle variations in freshwater condition: Bioindicators, ecological traits, and trophic interactions" https://doi.org/10.1016/j.ecolind.2022.109603

While it is expected that most #marine #microplastics accumulate in the #sediment, there is little knowledge of the effects of sediment-associated microplastics in #benthic organisms.

You can read more about this in our newly published #OpenAccess paper https://doi.org/10.3389/fmars.2022.1100567

Seasonal changes in environmental conditions need to be considered in #biomonitoring using #benthic #macroinvertebrates
Check out @AliRezaEs1365@twitter.com first paper from his PhD on how this can be done based on our #Karun case study. Well done Ali Reza 👏

And this is the dayjob (sometimes) deploying our Unisense #benthic chamber lander to measure #seafloor community respiration and #biogeochemical fluxes

A Mayfly in October here in the end of November.

This female mayfly was perched by the office door for ~2 days. Of course, I spent too much time observing her. It’s silly but I get sad when I know a mayfly won’t pass on their genes. Would have been too far to back to the ditch from where she emerged.
