;Microbes;"Gelatinous suspension feeders";"Crustacean suspension feeders";"Predatory jellies";Fishes;Mammals "Mechanisms of impact";"Unknown. Extra surfaces for attachment and new solutes from plume. New microbial community introduced from sediments. Microbes may be scavenged.Community structure and function will be impacted but difficult to predict specifics.";"Interference with feeding; salps and appendicularians are mucous feeders, so this would foul their feeding structures; suffocation/ smothering likely.";"Altered ingestion behavior because of selective feeding and loss of energy through parsing more useless particles (related to particle size); smothering unlikely; will olfactory sensors be clogged?";"Food web perturbation; stickiness of tentacles may be impacted by sediment sticking to it – capture efficiency would be reduced.";"Food web perturbation - their prey will be redistributed; suffocation possible at high sediment concentration and in OMZs.";"Food web dynamics are unlikely to affect them substantially as their prey is higher in the water column. However recent evidence points to deeper feeding than previously believed (Marsh et al. 2018)." "Scale of perturbation";"Range of microbes is greater than the plume and connectivity is high.";"Mortality may extend beyond the plume because of avoidance and migratory behavior.";"Escape depends on scale of plume in relation to range of organism – vertically and horizontally.";"May extend beyond the plume.";"Beyond the scale of the plume.";"Travel scales are large in comparison to plume. They are likely to avoid it." "Probability/ sensitivity";"Very high; sensitivity is high.";"Certain; sensitivity is higher than microbes (lethal impacts).";"High, but less sensitive than for gelatinous suspension feeders.";"Not as high as suspension feeders.";"Less sensitive if they can migrate away from the plumes.";Low. Recovery;"Recovery will be relatively quick once plume is gone.";"Dependent on advection from outside plume; distributions are broad, so probability is high at time scale of flow.";"Generation times and reproductive rates are unknown (months-years), advection will be more important to repopulation.";Unknown.;"Very long timescale; slow growth and reproduction times.";"High potential recovery from migration back into region after plumes have settled."
