We describe RAPID: a Real-time Automated Plankton Identification Dashboard, deployed on the Imager, high-speed line-scan camera that is connected to ship water supply and captures images of particles in flow-through system. This end-to-end pipeline for zooplankton data uses Edge AI equipped with classification (ResNet) model separates into three broad classes: Copepods, Non-Copepods Detritus. The results are transmitted visualised terrestrial system near real time. Over 7-days survey, Imager successfully imaged saved 128 million mesozooplankton size range, 17 which were processed real-time via AI. Data loss occurred along pipeline, mostly due processing limitation Nevertheless, we found similar variability counts classes output dashboard (after loss) post-survey entire dataset. concept offers rapid cost-effective method monitoring trends events at fine temporal spatial scales, thus making most continuous collection time allowing adaptive sampling be deployed.

Abstract Doliolids have a unique ability to impact the marine microbial community through bloom events and filter feeding. Their predation on large eukaryotic microorganisms is established evidence of smaller prokaryotic beginning emerge. We studied association between wild‐caught doliolids in Northern California Current system. were collected during identified at three different shelf locations with variable upwelling intensity. discovered associated range functional groups, which included free‐living pelagic Archaea, SAR11, picocyanobacteria. The results suggest possibility that could feed smallest members community, expanding our understanding doliolid feeding mortality.

Eastern Boundary Systems support major fisheries whose early life stages depend on upwelling production. Upwelling can be highly variable at the regional scale, with substantial repercussions for new productivity and microbial loop activity. Studies that integrate classic trophic web based production are rare due to range in body forms sizes of taxa. Underwater imaging overcome this limitation, machine learning, enables fine resolution studies spanning large spatial scales. We used In-situ Ichthyoplankton Imaging System (ISIIS) investigate drivers plankton community structure northern California Current, sampled along Newport Hydrographic (NH) Trinidad Head (TR) lines, OR CA, respectively. The non-invasive particles over 1644km winters summers 2018 2019 yielded 1.194 billion classified images. Combining nutrient analysis, flow cytometry, 16S rRNA gene sequencing mesoplankton underwater enabled us study taxa from 0.2µm 15cm, including prokaryotes, copepods, ichthyoplankton, gelatinous forms. To assess structure, >2000 single-taxon distribution profiles were analyzed using high correlations. Co-occurrences NH line consistently significantly higher off-shelf while those TR highest on-shelf. Random Forests models identified concentrations associated such as protists, Oithona appendicularians important co-occurrences line, TR, cumulative chlorophyll a importance. Our results indicate is driving intermittent systems supports temporal stability, further, connect diverse functionally redundant stable structure. Where more continuous primary may dominate patterns obscuring underlying role loop. Future changes strength likely disproportionately affect regions, activity enhances resilience.

Abstract Various iterations of shadowgraph imaging have been used to quantify zooplankton in situ with high spatial resolution. Because these systems can image relatively large volumes water, they are especially useful for resolving less common meso‐ or macrozooplankton taxa (< 50 ind. m −3 ), such as larval fishes and gelatinous animals. However, larger volume imagers typically integrated heavy towed vehicles deployed from research vessels, which introduces costs limits sampling approaches. Here we demonstrate that versatile configurations imaging, including modular benchtop, handheld, towed, compact vehicle (along customizable software), allow tailoring a variety marine freshwater settings (including mesocosms). These encompass suite possible architectures, designed adapting the depth field, acquisition rates, sensor configuration, deployment method fit wide range protocols, vertical resolution (~ 5 cm) adequate taxonomic capabilities > 0.5 mm organisms. The benchtop system facilitates an interactive approach observe behaviors optical properties. Video footage generates thousands regions interest min −1 target organisms variable orientations swimming postures. When conjunction build machine learning training libraries targeted toward rare morphologically diverse zooplankton, often includes stages economically valuable taxa. hardware software components increase affordability versatility while broadening scope scientific questions addressed by plankton systems.
