Brief offshore dalliance this week doing a few interesting tasks, such a tonic for the academic soul.

To quote idiosyncratic, post-punk artists Sea Power:
"The salt, the spray, the gorgeous undertow
Always, always, always the sea"

Key message: Measuring dry bulk density is as important as measuring organic carbon content when estimating organic carbon stocks.
Shouldn't surprise, but needs to be said.

Hey Kieran, just coming back, and down, an utterly transcendental Sigur RΓ³s concert in London over the weekend. An out of body experience. Any chance of a tune from those Icelandic wizards?

A stimulating week at #EGU25. Co-convened a #bluecarbon session, w/Phoebe Walsh presenting her latest PhD research on trawling impacts & seafloor recovery.

Shauna Creane & Aelita Totska presented a new sediment mobility tool, and Muireann Walsh gave her first PhD poster on Irish Sea morpodynamics πŸ‘
