fluxes are too big to be collected by sediment traps, but also because models aim to simplify the biotic compartments to facilitate calculations. Furthermore, jelly‐C deposits tend not to build up at the seafloor over a long time, such as phytodetritus (Beaulieu, 2002), being consumed rapidly by demersal and benthic organisms or decomposed by microbes. The jelly‐C sinking rate is governed by organism size, diameter, biovolume, geometry, density, and drag coefficients. In 2013, Lebrato et al. determined the average sinking speed of jelly‐C using Cnidaria, Ctenophora, and Thaliacea samples, which ranged from 800 to 1,500 m day−1 (salps: 800–1,200 m day−1; scyphozoans: 1,000–1,100 m d−1; ctenophores: 1,200–1,500 m day−1; pyrosomes: 1,300 m day−1). Jelly‐C model simulations suggest that, regardless of taxa, higher latitudes are more efficient corridors to transfer jelly‐C to the seabed owing to lower remineralization rates. In subtropical and temperate regions, significant decomposition takes place in the water column above 1,500 m depth, except in cases where jelly‐C starts sinking below the thermocline. In shallow‐water coastal regions, time is a limiting factor, which prevents remineralization while sinking and results in the accumulation of decomposing jelly‐C from a variety of taxa on the seabed. This suggests that gelatinous zooplankton transfer most biomass and carbon to the deep ocean, enhancing coastal carbon fluxes via DOC and DIC, fueling microbial and megafaunal/macrofaunal scavenging communities. However, the absence of satellite‐derived jelly‐C measurements (such as primary production) and the limited number of global zooplankton biomass data sets make it challenging to quantify global jelly‐C production and transfer efficiency to the ocean's interior. Monitoring Because of its fragile structure, image acquisition of gelatinous zooplankton requires the assistance of computer visioning. Automated recognition of zooplankton in sample deposits is possible by utilising technologies such as Tikhonov regularization, support vector machines and genetic programming.
