Modeling What We Sample and Sampling What We Model: Challenges for Zooplankton Model Assessment

Abstract: Zooplankton are the intermediate trophic level between phytoplankton and fish, and are an important component of carbon and nutrient cycles, accounting for a large proportion of the energy transfer to pelagic fishes and the deep ocean. Given zooplankton's importance, models need to adequately represent zooplankton dynamics. A major obstacle, though, is the lack of model assessment. Here we try and stimulate the assessment of zooplankton in models by filling three gaps. The first is that many zooplankton observ… Show more

“…To our knowledge, this study provides the first quasi regional zooplankton biomass model-data comparisons in the GoM along with the first model-data comparisons of size-specific zooplankton biomass and grazing rates. Such comparisons provide the first insights into the potential biases of traditional biogeochemical models pertaining to zooplankton dynamics (Everett et al, 2017). While the PBM shows broad agreement with zooplankton observations, some model-data mismatch occurs, particularly for LZ grazing rates.…”

“…accuracy of zooplankton abundance estimates from numerical models, such as three-dimensional physical-biogeochemical ocean models (PBMs), has been a major challenge in previous modeling studies as a result of sparse ship-based observations in most regions (Everett et al, 2017).…”

“…On long timescales it regulates atmospheric CO 2 on the basis of biotic uptake of carbon dioxide (CO 2 ) over vast oceanic regions and due to the export of photosynthetically fixed carbon into the deep ocean, which affects 20 the Earth's climate (Reid et al, 2009;Sigman and Boyle, 2000). Plankton ecosystem models are widely applied to understand marine biogeochemical cycles, by estimating fluxes of major elements, e.g., nitrogen, phosphorus, and carbon, as well as the sources and sinks of marine oxygen (Maier-Reimer et al, 1995;Six and Maier-Reimer, 1996;Schmittner et al, 2005;Bopp et al, 2013;Vallina et al, 2017;Everett et al, 2017;Ward et al, 2018). other models, e.g., Aumont et al, 2015), which we also employ for the OPEM configuration, limits both growth and N 2 fixation of diazotrophs to above 15 • C, f dia (T )_OPEM = max(1.066 T − 2.6, 0)/2…”

“…The relationship between phytoplankton and higher trophic levels is not straightforward, as zooplankton are the main energy pathway from phytoplankton to fish (Carlotti and Poggiale, 2010;Mitra and Davis, 2010;Everett et al, 2017). Zooplankton are any animals that float in the water and cannot progress against currents.…”
