  abstract = {{R}esearch cruises to quantify biogeochemical fluxes in the ocean require taking measurements at stations lasting at least several days. {A} popular experimental design is the quasi-{L}agrangian drifter, often mounted with in situ incubations or sediment traps that follow the flow of water over time. {A}fter initial drifter deployment, the ship tracks the drifter for continuing measurements that are supposed to represent the same water environment. {A}n outstanding question is how to best determine whether this is true. {D}uring the {O}ligotrophy to {U}l{T}ra-oligotrophy {PAC}ific {E}xperiment ({OUTPACE}) cruise, from 18 {F}ebruary to 3 {A}pril 2015 in the western tropical {S}outh {P}acific, three separate stations of long duration (five days) over the upper 500m were conducted in this quasi-{L}agrangian sampling scheme. {H}ere we present physical data to provide context for these three stations and to assess whether the sampling strategy worked, i.e., that a single body of water was sampled. {A}fter analyzing tracer variability and local water circulation at each station, we identify water layers and times where the drifter risks encountering another body of water. {W}hile almost no realization of this sampling scheme will be truly {L}agrangian, due to the presence of vertical shear, the depth-resolved observations during the three stations show most layers sampled sufficiently homogeneous physical environments during {OUTPACE}. {B}y directly addressing the concerns raised by these quasi-{L}agrangian sampling platforms, a protocol of best practices can begin to be formulated so that future research campaigns include the complementary datasets and analyses presented here to verify the appropriate use of the drifter platform.},
