TWR APEX BioGeoChem - Model BGC -Profiling Floats
APEX BioGeoChem (BGC) is Teledyne Webb Research`s (TWR) most requested sensor configuration after the basic Argo float. TWR begins with our field proven APF-11 controller, aluminum hull, lithium primary batteries, and Seabird SBE-41CP CTD. We added an Aanderaa (AADI) model 4330 dissolved oxygen optode and a WETLabs FLbb (chlorophyll_a and backscatter) to complete the package. If needed TWR can substitute either the WET Labs FLbbCD or a Triplet for the FLbb.
