Diel Vertical Migration<\/h3>\n

Many twilight zone animals migrate up to the surface at night to feed, and back down to depth during the day. This phenomenon, called “diel vertical migration” (DVM) is considered the largest animal migration on the planet. I am investigating which species migrate, the timing of their migration, and the environmental cues associated with their migration. In September, 2021, we conducted several deployments of a new large – volume eDNA sampler on the midwater robot Mesobot<\/em> to collect a time series of samples before, during, and after the evening upward migration.<\/p>\n

Environmental DNA (eDNA)<\/h3>\n

Environmental DNA can be thought of as a type of forensic analysis of ocean inhabitants. Instead of sampling animals, we can detect the traces of DNA that they leave behind.<\/p>\n

\u00a0Autonomous in situ eDNA sampling on Deep-See<\/h3>\n

Deep See is a new towed broadband acoustics and imaging instrument developed at WHOI by Andone Lavery (WHOI) and her team (Deep-See is pictured left; image by Veronique LaCapra). I have added an eDNA sampler that filters water in situ. <\/em>You can read more about it here<\/a>. We are able to sample adaptively, in response to observed acoustic backscatter from Deep-See and the shipboard echosounder.<\/p>\n

Tunicate evolution<\/h3>\n

Salps, pyrosomes, and doliolids are planktonic invertebrate chordates. They are in a group called the tunicates, and are related to benthic sea squirts. My\u00a0paper<\/a> on tunicate phylogeny was the featured article in the Journal of Plankton Research, and the cover photo of a salp (Cyclosalpa pinnata<\/em>) was taken by my PhD and postdoctoral advisor, Larry Madin<\/a>. You can read a news article about my research here<\/a>.<\/p>\n\t\t\t\t\"226_Annette_Govindaran.jpg\"\n\t
