I've done a blog for you all to read!

In it I talk about #geophysics in the @CEPHaS_Soil project, and how we're using it to better understand hydrodynamics in #agriculture.

The #ERT data is also being used for my @UniversiteLiege & @DocBGS PhD.

@Adrianchwhite I bought this some time ago and haven't got round to reading it yet...maybe I need to listen to a podcast on "how to read a lot", too

@sebuhlemann @SciPy_team @CEPHaS_Soil @Crop_Gas These are field data from a cross borehole setup

Mean of 0-20 cm layer from T corrected res models

Temporally co-located PR2 volumetric moisture sensor measurements at 10 cm depth, converted to gravimetric

Lab data on density, pore fluid conductivity, & CEC for W-S variables

[Russell Swift @Geo_RussS]

Cooking on gas with Waxman-Smits moisture content/resistivity relationships! 🔥

@SciPy_team minimize function working 📉

Time to expand to all @CEPHaS_Soil & @Crop_Gas soil samples to allow the estimation of #soil water content from our ERT monitoring #geophysics data ⚡💧

Awful customer service @qatarairways

Delayed for 24 hours? You are allowed 350 ml of water, 500 ml is forbidden

Contact customer service? 33 days, 5 emails, no response

Use live chat? Get cut off 4 times - the agent doesn't want to talk to you

Never flying with them again

A very productive hypothesis forming workshop was held last week. Great to see everyone in this hybrid format, and to work together on the project goals

Forbidden milkshake 🧋😋

#Soil samples made up to 150% volumetric water content, being filtered for pore water conductivity #geophysics measurements as part of the @CEPHaS_Soil project

[Russell Swift @Geo_RussS]

Time to get agitating!

Mixing up some #soil samples for pore water conductivity measurements for #geophysics calibration in the @CEPHaS_Soil project

Testing the thermal properties of the Malawian #soil cores - measuring thermal conductivity and effusivity for the @CEPHaS_Soil project

Just one week until the our @CIRIAupdates webinar, in partnership with @SOCOTEC_UK. Join us as we showcase developments in our PRIME technology & present case studies in assessing, monitoring & protecting the built & natural environment.

Cracking open some more Malawian Alfisol #soil cores today for the @CEPHaS_Soil project.

Looks like a good example of an infilled termite burrow in one, and some beautiful colour gradation in another

@al_corfield Train to Bristol for me this weekend £86 (super off-peak return)

Cost of fuel if I drive on my own in a car £32

[Russell Swift @Geo_RussS]

Lab work for the @CEPHaS_Soil project - density rings of Malawian Alfisol from various depths at our observatory

GELMON 22 (6th International Workshop on Geoelectrical Monitoring) is set to be online this November https://t.co/glh5tNhL6v

Uneaten Christmas Quality Street, littering the ocean floor. Can see a rogue Malteaser in there, too

[NHM_Bryozoa @BryozoanNhm]

Surprised to find these triangular diatoms littering the surface of a bryozoan from Galapagos.

[Russell Swift @Geo_RussS]

@DamienJougnot It's on the way, just out for comments now!

[Russell Swift @Geo_RussS]

@BritGeoSurvey There was a stoat crossing the road outside the front of BGS a few weeks back. Went under the hedge onto the site, so it may also be a BGS resident.

Neat graphical output looking at crop yields by continent.

Cereals are shown in the tweet, but graphs are customisable in the link. Plenty of crop types and countries can be selected.

[Hannah Ritchie @_HannahRitchie]

🌾Increasing crop yields across Sub-Saharan Africa: one of our most pressing challenges in the coming decades.

@sebuhlemann @DrHydrogeofizz @cbdawson In fairness, a lot of those questions were your fault!
