IsA Parameters and Protocols

Isfjorden Adventfjorden time series (IsA) has been sampled on a regular basis since December 2011. Sample processing either takes place on board, or in the UNIS laboratories immediately after returning from field. Core parameters that are collected on every sampling event are listed in the table bellow:
