Bronze and Iron Age farmers in the Middle East prioritised wine production over olive growing in times of climatic change. Researchers in our Department of Archaeology and @durhamearthsci.bsky.social analysed charred seeds and wood samples 👉 www.durham.ac.uk/news-events/...

Our sunflower experiment is coming along nicely. No clear relationship between soil amendment and growth yet. But I’m hypothesising we will see a difference in the actual flower and seeds. Time will tell…

Working on a Sunday to collect some heritage long-straw rye plants as part of a bread study - lovely field setting

Today we are coring soil again in Cumbria but today we have supervisors making sure we do it properly 😂

As an Aussie who has visited and marvelled at its beauty over 30 years ago it is disheartening to read of its decline and pressure to survive.

Our grass experiment is coming along very nicely in Cumbria. Rain and warm weather has helped. Now we leave it for a month and see what impact the soil amendments have had.

In Cumbria again today measuring our Miyawaki trees and seeds no if our grass experiments have started to sprout. 😁😁

Back in Cumbria - glorious weather for fieldwork - been worried about our Miyawaki trees but they are sprouting - and tonight we came across a herd of deers including an albino deer 😁 wow

This morning I am analysing some alcohol / spirit dated back to 1760… oh it smells heavenly. I wonder what carbon sources were used in its creation ???

1200 trees planted in a day - just another 800 to go. An amazing job by Ellie Ward and Myself although we are suffering from abundant nettle stings 😬

Ok. It looks like a more daunting task in the field compared to drawing up the designs on Google Earth - I barely see the car!!! Thank heavens for the LFG farmers who have come to the rescue - more photos tomorrow

No not yet. I’m hoping to present at Groundswell this summer. 😁

Shout out 📣 For those of you who follow us, you'll have had the pleasure of being whisked away to the silky, caramel fronds of a Sussex kelp bed thanks to the beautiful images and footage taken by Paul Boniface, from the amazing Sussex Underwater team.

Farmers and I have been battling for over 12 months to get a permit / license to repair non-functioning tidal gates, but it’s too late… the River Winster is now showing signs of decay and death - bureaucracy and stone walling has stopped us from stopping environmental damage

It was an honour and privilege to present and take part in the First UK kelp conference. May they continue around the country.

It was great talking to the Sussex Kelp Restoration Project today. For someone who has not analysed any Sussex kelp they were so welcoming and inquisitive it was amazing.

On the train to Brighten today to attend and present at the Kelp Summit 2025.

Out yesterday practicing our skills with the @bluerobotics.bsky.social BlueRov 2 underwater drone. Not as easy as it looks, especially when you didn’t grow up with PlayStations 🙈
