 #### SeaExplorer
 On SeaExplorer gliders, the various existing fluorescence sensors can be installed in either/both (depending on the sensor) the front wet payload section (called the nose cone) or the dry payload section in one of the four (4) puck ports. External mounting using the external puck mounts on the dry payload section is also feasible, but this configuration is rare. (we can add more details and photos too)
-The mounting options available for the different sensors on a SeaExplorer can be seen in {numref}`WetlabsSX`.
