As part of the Shelfbreak Productivity Interdisciplinary Research Operation at the Pioneer Array (SPIROPA) Project, twelve grazing experiments were conducted during each of three research cruises (April of 2018, and May and July of 2019) in the Middle Atlantic Bight to estimate community zooplankton grazing and net phytoplankton growth rates. Stations where the experiments were conducted were strategically located in one of three key cross-shelf water mass regimes: (1) at the shelfbreak front, (...
Show moreDaily zooplankton Grazing Experiments were conducted on each of three cruises as a component of the SPIROPA project. 12 experiments/Cruise, targeting 3 water mass regimes: shelf, shelfbreak front and slope waters.
Grazing experiment sample water was collected with a CTD/Niskin bottle rosette at depths ranging from surface (0 m) to 56m, targeting chl-a max if present. Two experimental treatments were incubated: 1. whole water to represent the entire plankton community and 2. <200 µm fraction of plankton community to estimate microzooplankton grazing impact.
