DBT Foldscope Phytoplankton Protocol

We developed this protocol as part of our DBT foldscope project on #Andamanplankton. The methods are based on commonly used techniques for sampling marine phytoplankton and have helped easily reveal Noctiluca, Ceratium, and various dinoflagellate and diatom species from the inshore waters of the Lohabarrack Sanctuary in South Andaman (Permit No. CWLW/WL/134(D)/272). Methodology: 1 litre…

The ocean-foldscope art co-lab

Some pretty shots of zoea pleopods and other crustacean body parts… (also, foldscope video is definitely where it is at for live zooplankton, all of these images are from live recordings – unfortunately our internet here in the Islands does not currently support such hefty uploads) #foldscopeart #oceanart #IndiaFoldscopePhase1 – DBT Foldscope Category B Project…

Magnifying a big Lucifer!

While the foldscope has proven great for phytoplankton sampling, the size range of our marine zooplankton (and the meroplankton in particular) has been much larger than the size best observable by foldscopes. But that doesn’t stop us from taking super magnified shots of them & then stitching the individual shots together to make a detailed…

Plant versus Animal

As the marine research officer at ANET, I have been involved in 2 coral reef ecology and marine conservation training programmes for tour operators working in the frontline of the marine tourism industry here in the Andamans. The first was in Wandoor in Feb-March 2019 for boat operators, glass-bottom-boat tour guides and snorkelling guides operating…

Phone Talk

I own a Moto G – 1st gen phone and I really like it :)! But what I don’t like is the images it takes with the foldscope. I recently realized that the quality of the phone camera matters a lot when taking good foldscope images. Here is the same amphipod photographed using my old phone…

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…

Plankton Practice

We are currently in the process of setting up our one-year project funded by India’s Department of Biotechnology (DBT) to promote the use of foldscopes in research (#IndiaFoldscopePhase1). Our proposed project #aims to not only understand diurnal and seasonal #plankton dynamics but also plans to establish predictive relationships between satellite-derived ocean surface metrics and in-situ…
