LTER base crews measuring physical, chemical, and plankton variables. Debi Fisk is measuring the volume pumped through a filter used to measure total particulate matter in the water column, and Joe Gressens is holding the Wisconsin net after taking a vertical tow for zooplankton. The elongated box to his left contains a 2 m long Schindler-Patalas style plankton trap that NTL-LTER designed and built.
