This week, we are having the full ensemble in action: At the “ORCESTRA Convergence”, all eight sub-campaigns of the ORCESTRA field campaign are gathered for a #workshop here in #Hamburg. The nearly 60 scientists are exchanging ideas and presenting their scientific progress before continuing collaboration in an ORCESTRA #hacking for the rest of the week.

Fieldwork is over, and my period has arrived. Field periods are a fact of life, but there's no doubt it can affect my work. To be able to get the hot and sweaty stuff done before its arrival feels like an Easter miracle.
Memorable past fieldwork periods include throwing up in a car park (happily, not in the cave!) and subsequently being gently fed home-made biscuits by my female colleagues until i felt better 
I have a new preprint out, which is about choosing the right solar regulator for solar-powered instrumentation.

Hope it's useful! #fieldwork #solar #solarpower #polar
doi.orgSolar power systems for polar instrumentation: why night consumption mattersAbstract. Autonomous instruments, powered using solar panels and batteries, are a vital tool for long-term scientific observation of the polar regions. However, winter conditions, with low temperatures and prolonged lack of sunlight, make power system design for these regions uniquely challenging. Minimising winter power consumption is vital to successful operation, but power consumption data supplied by equipment manufacturers can be confusing or misleading. We measured the night consumption (power consumption in the absence of sunlight) of 16 commercially available solar regulators and compared the results to the manufacturers' reported values. We developed a simple model to predict the maximum depth of discharge of a battery bank, for given values of regulator and instrument power consumption, solar panel size, location, and battery capacity. We use this model to suggest the minimum battery capacity required to continuously power a typical scientific installation in a polar environment, consisting of a single data logger (12 mW power consumption) powered by a 12 V battery bank and 20 W solar panel, for eight different models of solar regulator. Most of the tested solar regulators consumed power at or below the manufacturer's reported values, although two significantly exceeded them. For our modelled scenario, our results suggest that the mass of the battery required may be reduced by a factor of 26x by exchanging a solar regulator with high night consumption for a more efficient model. These results demonstrate that a good choice of solar regulator can significantly increase the chances of successful year-round data collection from a polar environment, eases deployment and reduces costs.
#ArtEveryDay is on tour for Cretan fieldwork. I'm enjoying painting little scenes from the week, although some are more rushed than others (and some more raki-affected than others).
It's been a while since the writing energy has hit. So today has been all about punching through a writeup of doing something useful with imperfect data

Without a doubt one of the most magical places on Earth: the Sahara Desert.
Visiting the breathtaking city of Ronda during a sedimentological research trip in 2022.
The Puente Nuevo bridge spans the 120-metre-deep El Tajo gorge carved by the Guadalevín River that runs through the city.
Many thanks to Heike Koch for taking the pictures!
It's a long drive from Casablanca to the Sahara of southern Morocco, but it’s well worth it for the incredible views along the way 
The landscape changes dramatically as you cross over the snow-covered Middle and High Atlas mountain ranges into the scorched plateaus of the Anti-Atlas.
Lucky enough to be invited to do some fieldwork in Crete over the Easter period.
My first time in Greece, and it's incredible. Fieldwork has so far been very productive, too!
Cretan Easter goes hard, midnight bonfire and fireworks/fire crackers/guns (
) to celebrate the resurrection.
Bonus dwarf mammoth skull!
The great tit breeding season has been kind of late, despite the very warm March and beginning of April. It's probably one of the latest in recent years. Only today we got the first confirmed great tit nest with 4 eggs. #ornithology #fieldwork

...and of course you wanted to see a stitched wide angle of #RSVAuroraAustralis parked in ice on a wonderful late winter evening...
Doing some CV-website updating and finding old maps.
Here are a few flights and drift tracks from SIPEX2 ice stations 6 and 7. Ship track is dashed, field site drift track solid sections along ship track, marked by start (pale cyan) and end (orange-red) points. Solid lines are helicopter lidar/imagery/infrared/radar survey tracks. Imagery is MODIS/Terra for a nearby date. Circa 2013, in @qgis - part published as figure 1 in doi:10.3189/2015AoG69A814

Returned from an expedition to the Lower Ice Lake ("Unterer Eissee") beneath Hallstätter Glacier #Dachstein #Austria with @rglueckler, Ulrike Herzschuh (both @awi) and Jakob Korneli (@unileipzig). We wanted to take lake sediment cores to reconstruct the vegetation development of the last c. 130 years.
We previously did some avalanche rescue training. Unfortunately, the snow and avalanche conditions prevented us from reaching our destination, and we had to return.

Snails of Cuba! In the end, we found 5 species, including the most endangered and arguably also most beautiful, Polymita sulphurosa. Unfortunately, we also encountered illegal sale of the shells on mountain pass.
Why? Project is on the evolution and conservation of these snails, led by Dr Bernardo Reyes in Cuba and working with colleagues from London zoo, Netherlands, Belgium, and Germany.
Trying to get my fediverse posting system sorted before #fieldwork this year. What are you all using to edit your @loops videos (ideally on your android phones)?
