Langseth Cruise MGL2207 in the Northern California Current in Mar and Jul 2022 (Collaborative Proposal: Are all cell surfaces the same? The effects of particle surface property on predator-prey interactions in the microbial loop) | Mucous mesh grazers including pelagic tunicates and thecosome pteropods play a key role in oceanic food webs. Using their fine mucous meshes, these pelagic grazers ingest a wide range of planktonic prey and link pelagic and benthic marine ecosystems. Characterizing the diet of this group is central to fully understanding marine food webs and developing accurate food web models. \n\nMicroscopy has largely been supplanted by other methods, but it remains valuable for its precision in determining cell size and morphology, which are key to characterize the diet and feeding mechanics of grazers. In this study, we use environmental scanning electron microscopy (ESEM) to examine the gut contents of several mucous mesh grazers from the Northern California Current (NCC) including Dolioletta gegenbauri, Thetys vagina, Pegea socia, Pyrosoma atlanticum, and Limacina helicina. Our findings provide size and taxonomic resolution of the prey of these mucous mesh grazers and expands the known prey size range for some species. In the results paper, we also discuss the advantages of using microscopy, including insights into prey morphology and integrity, which enhances our understanding of feeding selectivity, prey defenses, and the fate of grazed plankton in marine ecosystems. Our results reinforce the significant predatory role of mucous mesh grazers in planktonic ecosystems and food webs. \n\nThis dataset includes size measurements of prey items found in the guts of each gelatinous grazer species which were collected and processed in the NCC over two sampling seasons and oceanographic research cruises, as well as background oceanographic data for these stations. The dataset includes collection metadata, CTD summary data, image analysis metadata, grazer species information, prey ids, and prey counts.\n\ncdm_data_type = Other\nVARIABLES:\nstation_season_id (unitless)\nDateTime_Local_PT (unitless)\nstationID (unitless)\nseason (unitless)\nlatitude (degrees_north)\nlongitude (Long, degrees_east)\n...
