Field work took place in the mangroves of Tuxpan, at the northernmost coast of Veracruz. We chose to switch locations because the regular inundations of La Mancha lagoon made sap-flow monitoring very challenging.
It took a couple of weeks to get the rhythm right… learning curves!. We drilled a lot!, and broke more drill bits that we would have wanted too.
At first, we had all hands on a single drill point
but we managed to master the method
Eventually, we had a proper field lab running!
The drought was brutal. After three weeks of it, we all agreed we’ve never seen the wetland as dry as this:
Although Batis maritima is featured here instead of a mangrove, the mangrove sediments were looking pretty similar
The water table was well below 75 cm below the soil surface, and it stayed like that until the next full moon, when spring tides and rain upland managed to bring some water into the dry sediments.
This event gave us a unique opportunity to run localised irrigation experiments
oh yes! it was boiling hot!! – we brought a wee fan. It also helped keep the horseflies at bay
Throughout we had massive support from everyone in INECOL, the TPT team was brilliant, guiding us through the mangroves when we first arrived, letting us use their working space and helping out in every little need!
We are deeply grateful to all!, specially Arlene, Moi and Mau for being there every step of the way. To Alvaro for all his knowledge, patience and leg support carrying batteries in and out of the mangrove two times a day every single day.
