Biodiversity, Ecology, and the Biological Carbon Pump in the Ocean Twilight Zone

Agenda

September 13-15th and 18-20th, 2023

9:00am-5:00pm daily

Plenaries will be held in Redfield Auditorium (Woods Hole Village Campus) and break out sessions will be located throughout the village campus

Each day workshop shuttle will pick up participants at hotels and bring them to the meeting venue, returning particpants to hotels at the end of the day.
