RBRmaestro³ multi-channel CTD logger
To expand our coastal oceanographic monitoring, we have integrated the RBRmaestro³ multi-channel CTD logger into our long-term research infrastructure. This advanced instrument delivers high-accuracy physical and biogeochemical profiling -measuring conductivity, temperature, and depth (pressure) with ultra-fine resolution and fast response times. Capable of integrating up to ten simultaneous sensor channels (including optical dissolved oxygen, fluorescence, turbidity, and PAR) alongside high-frequency sampling up to 16Hz, the logger provides high-resolution data on water column structure, seasonal stratification, and local hydrographic dynamics.
Deploying this platform enables high-resolution characterization across our focal marine habitats along the Eastern Mediterranean shelf. We are utilizing the system for routine, high-precision vertical profiling observations across both shallow-to-mesophotic rocky reefs and the extensive soft-bottom shelf environment. By capturing environmental gradients—from thermal fluctuations and salinity shifts to dissolved oxygen and primary productivity indicators—this new CTD provides the critical baseline data required to assess ecosystem shifts, benthic-pelagic coupling, and long-term climate impacts in a rapidly warming basin, replacing the Seabird 19V2 instrument we have been using so far.
