Seamount larval drift was estimated from a temperature model
Little knowledge exists on the pelagic larval durations (PLDs) of seamount species and only a small number of deep‐sea species have been studied (Hilário et al., 2015 ).
This paper needed a number for how long seamount larvae stay in the water. Direct measurements are scarce: little is known about pelagic larval durations of seamount species, and only a small number of deep-sea species have been studied. So they used a community-averaged temperature model, then checked it against a coral they already know.

Thus, PLD in this study was calculated using a community-averaged model by O'Connor et al. (2007) of the temperature dependence of larval development, as well as previous biophysical models for the deep sea.

As a test case for applying the model to deep-sea organisms, we ensured that the model (49.5 days at 8°C) represented well the PLD of the deep-sea coral Lophelia pertusa (42–56 days at 8°C).
