#Ditches

A framework for the sustainable maintenance of permanent runoff management structures in rainfed agriculture under climate change

https://www.sciencedirect.com/science/article/pii/S0301479725006942

A topic that I have loved from the time of my PhD thesis and now updated in collaboration with the colleagues from #INRGREF and UMR LISAH

Expect more soon, other manuscripts are under preparation on this topic!

Schematic - ash mass concept. For a column of peat exposed to drainage, the surface peat is exposed to more oxidation and therefore carbon is lost but the ash content is conserved. This demonstrates how carbon loss can be calculated using the remaining ash in the peat column. The terms correspond to the terms in Equations 1-5, with r = reference layer and i = impacted layer. The dashed line in the second column indicates the loss. The loss in thickness due to shallow subsidence results from the difference in the bulk densities, whereas the secondary subsidence results from the loss in elevation due to oxidation, driven by the differences in ash mass.

Maps - coring locations, ditches by age, dominant vegetation communities. Contours correspond to estimated peat depths based on Oaks and Whitehead (1979). Coring locations are indicated by the following numbers: 1. GDS519, 2. GDS520, 3. GDSW1, 4. GDS77, 5. GDS83, 6. GDS528, 7. Interior-South, 8. Interior-North, 9. GDS96, 10. GDS-P + H, 11. GDS542, 12. GDS-04-14-2022-1A, 13. GDS-04-14-2022-1B. (a) Map of Great Dismal Swamp National Wildlife Refuge (GDS NWR) showing coring locations and binned ages of ditch, canal, and railroad installation, (b) Map of GDS NWR showing dominant vegetation communities within GDS NWR. The “early successional” (marsh) area to the southeast of Lake Drummond corresponds to the area burned in both 2008 and 2011. The area bounded by shading represents the Great Dismal Swamp NWR boundary.

charts - Carbon stocks and accumulation at GDS sites. (a) Carbon stocks for all sites, including two calculations for heavily impacted sites (GDS-W1, GDS-77, and GDS-P&H). Stars indicate calculations from ash mass from the lower depths of each of those cores, while the other (b) calculation for these sites indicates the lower ash mass calculation using the average of other less disturbed sites. Burn scar cores calculations are down to the first charcoal peak (a) and down to the second peak (b) for GDS-Interior-North and South. (b) Carbon accumulation and loss rates for cores with vegetation reconstructions. Negative values indicate carbon loss values.

Vance showed his debate persona was a lie, just hours after his overly nice #matchup with #TimWalz in the #vicepresidentialdebate.

A bit of #fun. My attempt to #map #historic #dialect terms for the #stickleback. Which is your #favourite? What #names are #local to you? When did you last see/catch one? They used of congregate in their millions in #Fenland #ditches and #dykes. #Farmers even used #fresh sticklebacks as #manure, spread straight on to their #fields. I hope you like the #scale. Enjoy! #Fish #Language #Biodiversity #Crisis #River #Stream #Pollution #UK #England #Wales #Scotland #NorthernIreland #Ireland #IsleOfMan

A simple map of the British Isles in light green. On it, in black text, old names for the stickleback in their approximate geographical location. Certain locations in ordinary text; uncertain at 45 degree angle. Title 'Dialectal terms for the Stickleback'. Image of stickleback top left. Map scale based on average length of a stickleback!

Mornin’.

Blackthorn be flowering.
Birds be singing.
Bees be happy.

Have a great one!
