Dataset: Multiple Opening and Closing Net Environmental Sampling System (MOCNESS) water filtering volumes from 2018 and 2019 taken in the Northern California Current waters.

Sampling happend along two transects in winter and in summer 2018 and 2019. One transect was off of Trinidad Head, CA and the other Newport, OR (See Figure in Supplemental Docs). Each transect consisted of five target stations during the day and at night with replicate tows at each station. However, this sampling design was often modified at sea. Please refer to the dataset for completed stations.

To sample a range of zooplankton simultaneously, a coupled Multiple Opening and Closing Net Environmental Sampling System (MOCNESS) consisting of a 4m2 net fitted with 1 mm mesh and a 1 m2 net with 150 μm mesh was used (Guigand et al. 2005). The former is referred to as the Moc4 and the latter the Moc1. The Moc4 and Moc1 each have 5 nets (numbered 0-4) to sample discrete depths. Please see above for depth descriptions. All tows were sent to a target depth of 100 m.
