IN SITU MARINE SAMPLE COLLECTION SYSTEM AND METHODS

摘要

According to one aspect, the invention relates to a marine sample collection system adapted for in situ use. The system includes a first filter head and a second filter head for filtering material of interest from ambient marine fluid passing therethrough and a respective filter flow meter disposed downstream of each of the filter heads for measuring volumetric flow through each filter head. The system also includes a pump downstream of the filter heads for inducing flow through the filter heads and an outlet flow meter disposed downstream of the pump for measuring volumetric flow through the pump. An optional controller compares a sum of an output of the flow meters associated with the first and second filter heads and an output of the outlet flow meter to determine if there is leakage in the system.
