Feeling around a muddy seagrass bed, on the bottom of an estuary, with almost zero visibility, for misplaced sediment probes.
The question for that answer is “How did you spend your morning?”
It’s definitely the kind of scientific experience which will be fondly recalled from the safety of dry land, after a hot shower. In fact, it wasn’t all bad, except when I forgot to clear my snorkel after the tenth dive and inhaled a glob of muddy, brackish water. The work was for a project studying the difference in sediment chemistry between seagrass beds during periods of light and dark – the plants photosynthesise, releasing oxygen into an otherwise oxygen-poor environment. The early results look interesting, though it might be hard to tease out any major trends from the natural variability. Let’s hope the acid in my stomach deals with any nasties in the water, eh?
