McLane also supports a portfolio of sampling tech- nologies, including the Imaging FlowCytobot (IFCB), alongside its ? agship Sediment Trap product line.

All McLane instruments are engineered for the de- mands of long-term, time-series deployments in both open ocean and freshwater environments. They play a role in global research programs and expeditions, including initiatives such as the Ocean Observatories

Initiative, GEOTRACES, and the RAPID array.
