NIRVANA in the Field
Fieldwork
Many of our projects contain a field component. Over the past few years, NIRVANA Lab members have sailed on sampling expeditions from the Subarctic to the Southern Oceans. Below is a list of the major field campaigns that we've been involved with. Be sure to check back periodically, as we are always heading out on new adventures!
