In addition, McLane maintains a line of samplers such as the

Imaging FlowCytobot (IFCB) as well as their ? agship prod- uct, the Sediment Trap, and a line of wire crawling pro? lers.

McLane instruments are all designed to withstand the rig- ors of long-term time-series open ocean and freshwater de- ployments. McLane products are central to many long-term global research projects and cruises including such initia- tives as OOI, GEOTRACES, and the RAPID array.

McLane’s most recent instrument is the Suspended Par- ticulate Rosette Sampler (SuPR), a high-volume time-se- ries sampler that autonomously collects 14 water samples
