The slide of my 3min presentation entitled "Rocky Tidal Pools - Carbonate chemistry, diurnal variability and calcifying organisms in future CO2 conditions". It shows coastal variability (lack of observation and understanding - seldom integrated in predictive climate models), what tidal pools are and what tidal pool variability is in pH, with and without artificially added CO2. And how this relate to the net calcification rate in the community.

Should I have submitted my #vEGU21 presentation to @EGU_BioGeo instead of @EGU_Ocean session 🤨?

Maybe. Or not.

Anyway. I talked for 2 minutes about #biogeochemistry of #tidalpools. My display material : meetingorganizer.copernicus.org/EGU21/EGU21-...

Feel free to start a discussion here !

Before #EGU22 is over, @annette_eicker handed over the @EGU_Geodesy division vOSPP award from #vEGU21 to Sebastian Strasser from @tugraz

Attending #vEGU21 was awesome, but I'm never doing a nighttime conference again! After 15hrs of sleeping and an afternoon outside, I have finally stopped feeling like a zombie!

Thanks to all who attended our #vEGU21 @EGU_Atmos session on "Chemistry, Aerosols and Radiative Forcing in CMIP6-era models" even though it was almost the last session of the last afternoon. Really enjoyed hearing about ongoing analysis. See more at...

CO Meeting Organizer EGU21 The surface of Mars is riddled with dunes that form by accumulating sand particles that are carried by the wind. Since dune geometry and orientation adjust in response to prevailing wind conditions, the morphometrics of dunes can reveal information about the winds that formed them. Previous studies inferred the prevailing local wind direction from the orientation of dunes by manually analyzing spacecraft imagery. However, building a global map remained challenging, as manual detection of individual dunes over the entire Martian surface is impractical. Here, we employ Mask R-CNN, a state-of-the-art instance segmentation neural network, to detect and analyze isolated barchan dunes on a global scale.We prepared a training dataset by extracting Mars Context Camera (CTX) scenes of dune fields from a global CTX mosaic, as identified in the global dune-fields catalog. Images were cropped and standardized to a resolution of 832x832 pixels, and labeled using Labelbox’s online instance segmentation platform. Image augmentation and weight decay were employed to prevent overfitting during training. By inspecting 100 sample images from the validation database, we find that the network correctly identified ~86% of the isolated dunes, falsely identifying one feature as a barchan dune in a single image.

Wanna learn more about how to map surface winds on Mars from dunes using machine learning? Make sure to check out @Liorruba’s #vEGU21 invited presentation @ 9:05 am CEST/12:05 am PDT!

The upside of a nighttime conference due to time zones is that I have the full day to do other things. The downside is that my brain is so tired but so caffeinated that I can’t work and can’t nap for the entire day. So all I can do is be on Twitter. #vEGU21
