- Typically station operations start with the CTD, then Secchi disk (on all daylight stations), vertical net tows (Pairovet, PRPOOS) next, followed by towed Manta & Bongo nets. The Secchi disk is deployed during daylight AFTER the CTD EXCEPT on the morning "prodo" (primary productivity 14C uptake incubation experiment) stations on Lines 93.3 through 76.7. On prodo stations the Secchi is the first station operation since the Secchi depth & depth of chlorophyll max are used to calculate the prodo bottle sampling depths. Net tows may be the first station operations if the prodo station arrival time is too early for the LAN (local apparent noon) incubation start time.
- SCCOOS 20m isobath station coordinates (lat-lon) are adaptable to tidal or seasonal bottom depth changes; the objective is a ~20m bottom depth. Depending on sea state, visibility, boat traffic, or objects (potential hazards such as lobster traps) in the way. The exact station position may shift around the 20m isobath, often slightly deeper.
- A bucket thermometer may be deployed on all stations if a thermosalinograph (TSG) is unavailable.
