Rockpooling and nature journaling the day before the #ICESASC26 in Brest. Tides and the Atlantic shores with their massive algae are a miraculous thing when you are used to the microtidal Mediterranean 🤩

First day at the @icesmarine.bsky.social #ICESASC26 in Brest and already feeling like it is a blast! Fantastic plenary and round-table discussions to warm up for the "proper" scientific sessions coming up after lunch! Not to mention the joy of meeting amazing scientists, collaborators & friends...

Diving over a #rhodolith bed the other day. Rhodoliths are calcareous red algae that are not attached to anything and just form little balls on the seabed. They are a highly biodiverse habitat and I saw so many species I have never seen before! Spot the cheerleeder #crab!
A very long-legged crab with little flappy red algae growing on its legs for camouflage. It sits on a muddy seafloor with more red algae and is basically not visible.

inaturalist•org Update on June 11, 2025 9:15pm EDT “We are not giving Google special access to your iNat data, and we have no obligation to use Google's infrastructure…If the demo… is not helpful, compromises data quality, has outsized environmental impacts, or is … too flawed, we will not keep it.”
We recognize that this announcement has caused a lot of upset and confusion among people who care deeply about iNaturalist. In the hundreds of comments, we hear that many people feel betrayed, disrespected, and without agency. We sincerely apologize.
With respect for the ethical and environmental concerns raised, we'd like to offer more clarity about our plans with this grant and program. We know that trust is not easily rebuilt, but we'd like to try.

First, to clarify some things we did not clearly communicate:

1. We are not replacing or changing the current human-curated system of identifications. Many of you have rightly pointed out that this is at the heart of iNat, and we wouldn't dream of doing away with it. Anything we explore with Al would only be meant to enhance the experience of some users: by, for example, providing an interesting tip about identifying the species, suggesting that the photographer try to capture a particular aspect of the plant or animal that might aid a human identifier, or explaining the computer vision's logic for the identification it's suggested.
2. We are not giving Google special access to your iNat data, and we have no obligation to use Google's infrastructure as part of this grant. Google is providing funding and advice on how to potentially leverage Al.
3. Naturalist has successfully incorporated machine learning and computer vision (kinds of Al) since 2017, with a very small footprint (primarily three machines running in spaces we control). We understand that new technologies can have much larger environmental impacts, and we aim to quantify the environmental footprint of Naturalist's infrastructure for 2025 and beyond.
4. This grant funds our team exploring new ways to surface and organize helpful identification comments - and if the demo we create is not helpful, compromises data quality, has outsized environmental impacts, or is overall too flawed, we will not keep it.

This project is just getting off the ground, and we …Done

The Naturalist community has always been a core partner in informing the direction of the platform, and we appreciate and hear your feedback (including but not limited to):
• We understand that you are concerned about inaccurate, out-of-context and/or hallucinated information being provided by a tool like this. We agree that any Al-provided information be clearly labeled as such and that there be a way to upvote/downvote or otherwise flag potentially misleading information, and we are excited to explore more ways for how this may happen.
• We hear that people would like to be able to understand and control how their data is used on and beyond iNaturalist. On iNaturalist, you own the copyright to your data, and iNaturalist Terms of Use prohibit the use of data for commercial Al training. Whether commercial Al companies are beholden to copyright law or terms of use or can argue "fair use" of publicly accessible data is being worked out in the courts and is something we are paying attention to.
• Most importantly, the community will be involved in the creation of this and any major new features.
We will not be implementing any new changes to what you see on iNaturalist right now without involving the community. Our plan is to have an initial demo available for select user testing by the end of 2025. If you have more feedback, ideas, concerns, or questions you'd be willing to share, please use this form so we can more easily keep track of them.
Additionally, if you would like to attend a virtual Q&A session to have some of this discussion in real time, please let us know in this form (more details to be determined).
Again, the project funded by this grant is just getting started. We will proceed carefully and respectfully, and we're immensely grateful for this incredible and engaged community.

Last week we explored an area with our new ROV and came across this gorgeous field of sabellid #polychaete worms. We don't know the species and generally not much about these aggregations. But they are very beautiful! #wormwednesday
A low angle view of a dense aggregation of sabellid worms. These live in tubes which are whitish and upright and from their top the worm emerges. Only their tentacular crowns are visible - a feathery, flowery light blue crown with a few dark spots. The sabellid field is bright in the foreground,  illuminated by the lights of the remotely operated underwater vehicle, and dark blue above.A view of the same sabellid field from.a higher angle - the field of feathery crowns stretches far into the background of the photo until.it becomes one with the dark background.

Some beautiful #nudibranchs from the last dives. Amazing shapes and colours! 😍
A photo of the nudibranch Polycera quadrilineata. It sits on a salp, is green-grey with orange stripes, and has four "mouth tentacles". The nudibranch Edmundsella pedata. It is pink with darker purple cerata (filaments arising from the back) which have white tips. The nudibranch Antiopella crisata. Its cerata are ballon-like elongated structures arising from its back. It is beige-transparent but the tips of the cerata are blue-violet.The nudibranch (in the wider sense, sacoglossan) Elysia rubeni. It is green, and shaped like a leaf. It has golden speckles all over, white, larger specks along the margins, and blue dots on its back and head. It is only 5 mm long.
