Time to Tow!

Finally our field season has started! Now that the Southwest monsoon and Northeast monsoons have passed our islands, we are out weekly to collect zooplankton using our 200um net, purchased with funds from the DBT foldscope grant (#IndiaFoldscopePhase1).

Our objective is to detect daily, lunar and seasonal cycles in meroplankton abundance. Our surveys are revealing stark differences between day and night! New moon and full moon phases! We are catching everything from copepods to fish larvae, even the occasional octopus baby! (#AndamanPlankton). Some of these zooplankton are too big for the foldscope so we do some of our preliminary analysis using a simple 20x dissection scope. Then we isolate certain critters & photograph them using the foldscope 🙂

Next post, Andaman internet permitting, we hope to share some of these foldscope images.

    Fantastic! This is one of the project I want to keenly follow. Please keep sharing updates.
    For the bigger objects you can use the lens attached to the light module given with the foldscope kit, it works pretty well.

    Wow. We are all transfixed – and will follow your expedition closely. It’s moments like this is why we built the foldscope community. Your work daily will alspnjnspire literally hundreds of thousands of kids who can follow you along. Wow wow wow.
