Abstract The Marine Biogeochemistry Library (MARBL) is a prognostic ocean biogeochemistry model that simulates marine ecosystem dynamics and the coupled cycles of carbon, nitrogen, phosphorus, iron, silicon, oxygen. MARBL component Community Earth System Model (CESM); it supports flexible configuration multiple phytoplankton zooplankton functional types; also portable, designed to interface with circulation models. Here, we present scientific documentation MARBL, describe its in CESM2...
Abstract The rise of in situ plankton imaging systems, particularly high‐volume imagers such as the In Situ Ichthyoplankton Imaging System, has increased need for fast processing and accurate classification tools that can identify a high diversity organisms nonliving particles biological origin. Previous methods automated have yielded moderate results either resolve few groups at accuracy or many relatively low accuracy. However, with advent new deep learning convolutional neural networks...
Abstract Among marine organisms, gelatinous zooplankton (GZ; cnidarians, ctenophores, and pelagic tunicates) are unique in their energetic efficiency, as the body plan allows them to process assimilate high proportions of oceanic carbon. Upon death, shape facilitates rapid sinking through water column, resulting carcass depositions on seafloor (“jelly‐falls”). GZ thought be important components biological pump, but overall contribution global carbon fluxes remains unknown. Using a...
Plankton community models are critical tools for understanding the processes that shape marine plankton communities, how communities impact biogeochemical cycles, and feedbacks between structure function. Here, using flexible Marine Biogeochemistry Library (MARBL), we present Size-based ECological TRAits (MARBL-SPECTRA) model, which is designed to represent a diverse while remaining computationally tractable. MARBL-SPECTRA composed of nine phytoplankton six zooplankton size classes...
Abstract Although zooplankton play a substantial role in the biological carbon pump and serve as crucial link between primary producers higher trophic level consumers, skillful representation of is not often focus ocean biogeochemical models. Systematic evaluations models could improve their representation, but so far, skill assessment Earth system model (ESM) ensembles have included zooplankton. Here we use recently developed global, observationally based map mesozooplankton biomass to...
Summary Chemical proteomics enables the global assessment of small molecule-protein interactions in native biological systems and has emerged as a versatile approach for ligand discovery. The range molecules explored by chemical has, however, been limited. Here, we describe diversity-oriented synthesis (DOS)-inspired library stereochemically-defined compounds bearing diazirine alkyne units UV light-induced covalent modification click chemistry enrichment interacting proteins, respectively....
We sampled a front detected by SST gradient, ocean color imagery, and Spray glider south of San Nicolas Island in the Southern California Bight between 14 18 October 2010. with an unusually extensive array instrumentation, including Continuous Underway Fish Egg Sampler (CUFES), undulating In Situ Ichthyoplankton Imaging System (ISIIS) (fitted temperature, salinity, oxygen, fluorescence sensors), multifrequency acoustics, surface pelagic trawl, bongo net, neuston net. found higher greater...
Climate change may impact ocean ecosystems through a number of mechanisms, including shifts in primary productivity or plankton community structure, acidification, and deoxygenation. These processes can be simulated with global Earth system models (ESMs), which are increasingly being used the context fisheries management other living marine resource (LMR) applications. However, projections LMR-relevant metrics such as net production vary widely between ESMs, even under identical climate...
Underwater imaging resolves plankton patch structure for 36 taxa in continental and oceanic waters of a western boundary current.
'Big data' are becoming common in biological oceanography with the advent of sampling technologies that can generate multiple, high-frequency data streams. Given need for 'big' ocean health assessments and ecosystem management, identifying implementing robust efficient processing approaches is a challenge marine scientists. Using large plankton imagery set, we present two crowd-sourcing applied to problem classifying millions organisms. The first used traditional by asking public identify...
Got “Big Data”? Not sure how best to use it? Big Data is becoming an important facet of aquatic ecology, and researchers must learn harness it reap the rewards using it. The benefits are many, include advancements in scientific understanding at larger scales higher resolution, applications improving environmental management policy, public engagement. We aim demystify for individual scientists, provide some food thought ecology community on develop this sphere. To achieve this, we highlight...
Abstract Eddies can enhance primary as well secondary production, creating a diverse meso- and sub-mesoscale seascape at the eddy front which affect aggregation of plankton particles. Due to coarse resolution provided by sampling with nets, our knowledge distributions these edges is limited.

Abstract. In marine ecosystems, most physiological, ecological, or physical processes are size dependent. These include metabolic rates, the uptake of carbon and other nutrients, swimming sinking velocities, trophic interactions, which eventually determine stocks commercial species, as well biogeochemical cycles sequestration.

Abstract. The Arctic Ocean experiences significant seasonal to interannual environmental changes, including in temperature, light, sea ice, and surface nutrient concentrations, that influence the dynamics of marine plankton populations. Here, we use a hindcast simulation (1948–2009) size-structured communities, ocean circulation, biogeochemical cycles order better understand how changes environment phytoplankton physiology, community structure, trophic dynamics, fish production Ocean. growth...
Abstract Doliolids are common gelatinous grazers in marine ecosystems around the world and likely influence carbon cycling due to their large population sizes with high growth excretion rates. Aggregations or blooms of these organisms occur frequently, but they difficult measure predict because doliolids fragile, under sampled conventional plankton nets, can aggregate on fine spatial scales (1–10 m). Moreover, ecological studies typically target a single region site that does not encompass...
