log in [Antarctic krill schooling: Rotation order parameters] - Rotation order parameters in each trial of Antarctic krill in lab experiments at Palmer Station, Antarctica in November 2022. (Collaborative Research: Individual Based Approaches to Understanding Krill Distributions and Aggregations) Laboratory experiments were conducted on schools of Antarctic krill in the novel annular flume at Palmer Station, Antarctica, in November 2022.  Using overhead camera along with stereophotogrammetry system the swimming trajectories of krill were recorded while altering flow and light levels in the tank. \n\nThe purpose of the study is to understand how Antarctic krill schooling structure changes under environmental cues such as flow and light, with the hope that distribution of these important species can be predicted through knowledge of the environment in the wild. Southern Ocean ecologists, biologists, and oceanographers in general could benefit from this work. Kuvvat Garayev and David Murphy from University of South Florida were responsible for the collection and interpretation of data.\n\ncdm_data_type = Other\nVARIABLES:\ndate (units)\nfile_name (unitless)\ntrial (unitless)\nflow (unitless)\nlight (unitless)\nkrill_density (krill/L)\nkrill_total (unitless)\nkrill_tracked (unitless)\nOr (unitless)\nimage (unitless)\nmean (unitless)\nstd (unitless)\nimage_file (unitless)\ncoordinate_file (unitless)\n BCO-DMO bcodmo_dataset_923518_v1

These data were collected as part of the following study:\n\nData collected as part of this study include nitrogen isotope ratio data for coral tissue and skeleton of the scleractinian cold-water coral Balanophyllia elegans collected at Friday Harbor, WA. Data was collected between March 2019 and August 2021. These data include paired measurements of the N isotope ratio (d15N) of coral tissue and skeleton. Tissue was measured using and Elemental Analyzer (EA)-coupled Isotope Ratio Mass Spectrometer (IRMS) and skeleton samples were first dissolved and organic nitrogen was oxidized to nitrate with persulfate before being run on a GC-IRMS with the denitrifier method. These data also include the results of two culture experiments with the same species of corals. The corals in the first culture experiment were fed Artemia diets with different known d15N in order to quantify change in the tissue d15N in response to a change in the food source and to determine the offset in d15N between the coral tissue and its diet. The starvation trial culture experiment was conducted to evaluate the effects of starvation on the d15N of coral tissue. For both experiments coral tissue was analyzed using an EA-IRMS. This data also includes the d15N of the respective Artemia diets. Finally, included in this data is hydrological and particulate matter data collect at the site the corals were collected (near Friday Harbor, WA). This data includes nitrate d15N and d18O, suspended particulate organic matter d15N, net tow material d15N, and data collected from a CTD profiler. This data enhances the understanding of cold-water coral diet and trophic position. This data improves the understanding of the relationship between surface nitrate d15N and the d15N recorded in the coral skeleton which is useful for enhancing the resolution of coral d15N paleoproxies.\n\ncdm_data_type = Other\nVARIABLES:\nStation (unitless)\nFile_name (unitless)\ntime (Cast_time_utc, seconds since 1970-01-01T00:00:00Z)\nlatitude (Start_latitude, degrees_north)\nlongitude (Start_longitude, degrees_east)\nPressure (decibar (db))\n...

However, it remains unknown whether any signals could enable larvae to navigate over large scales. We tested whether flow-induced larval behaviors vary with adults' physical environments using congeneric snail larvae from the wavy continental shelf (Tritia trivittata) and from turbulent inlets (Tritia obsoleta). This dataset includes observations of larvae in turbulence, in rotating flows dominated by vorticity or strain rates, and in rectilinear wave oscillations. Larval and water motion were observed using near-infrared particle image velocimetry (IR PIV), and analyses identified threshold signals causing larvae to change their direction or magnitude of propulsive force. The two species reacted similarly to turbulence but differently to waves, and their transport patterns would diverge in wavy, offshore regions. Wave-induced behaviors provide evidence that larvae may detect waves as both motions and sounds useful in navigation.\n\ncdm_data_type = Other\nVARIABLES:\nfile_name (unitless)\nlarval_stage (unitless)\nspecies (unitless)\nflow_tank (unitless)\ndirection (unitless)\nx (Longitude, centimeters (cm))\nz (centimeters (cm))\nuf (centimeters per second (cm/s))\nwf (centimeters per second (cm/s))\nub (centimeters per second (cm/s))\nwb (centimeters per second (cm/s))\nlarval_axial_rotation_ang (radians)\nlarval_propulsive_force (N)\npropulsion_direction (radians)\ndissipation_rate (m^2 s^-3)\nhorizontal_comp_of_vorticity (s^-1)\nacceleration (meters per second (m s^-2))\nstrain_rate (s^-1)\n https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_739790/index.htmlTable https://www.bco-dmo.org/dataset/739790 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_739790.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_739790&showErrors=false&email= BCO-DMO bcodmo_dataset_739790
log in [Winter temperature data from northeast Pacific embayments] - Winter temperature data from loggers placed in shallow subtidal areas in the northeast Pacific from Oct 2019 to Jul 2024 (Collaborative Research: Tracking fine-scale selection to temperature at the invasion front of a highly dispersive marine predator) Dataset includes winter temperature logger data for a suite of embayments in the northeast Pacific. Data were collected as part of an NSF-funded project on invasive European green crab adaptation; loggers were placed in the shallow subtidal in areas determined by Washington Sea Grant's Crab Team to be good environments for green crabs. Loggers were placed by multiple collaborators without a fully standardized approach; metadata are incomplete but include all available information. Loggers used were iButtons and HOBO pendant loggers. Two loggers were placed at each site in the shallow subtidal with the goal that they were always submerged in water while deployed (i.e., not emersed). Logging frequency depended on the monitor type; iButtons captured water temperatures every 2.15 hours, and HOBO loggers recorded water temperature every 30 minutes over the winter. Deployment duration varied between years and sites, but typically ran from October - April.\n\ncdm_data_type = Other\nVARIABLES:\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nLocal_DateTime (unitless)\nTemperature (degrees Celsius)\nFile_Name (unitless)\nSiteNumber (unitless)\nSiteName (unitless)\nHabType (unitless)\nType (unitless)\nModel (unitless)\nSerialNumber (unitless)\nLoggerStartDate (unitless)\nDeploymentDate (unitless)\nDeploymentTime (unitless)\nDeploymentDateTime (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nDeployedBy (unitless)\nRetrievalDate (unitless)\nAnchorType (unitless)\nTimeVar (seconds)\nNotes (unitless)\n BCO-DMO bcodmo_dataset_949897_v1

(Collaborative Research: From hot to cold in the dark - shifts in seafloor massive sulfide microbial communities as physical and geochemical conditions change after venting ceases) Synchrotron micro-probe X-ray diffraction data were collected for seafloor sulfide deposits. Seafloor sulfide mineral samples were collected from hydrothermally active chimneys and inactive off-axis massive sulfide deposits at East Pacific Rise (EPR) 9.50°N in 2019-2021 on cruise AT42-09. Samples were collected using the HOV Alvin. Samples were placed in a positive-pressure glove bag flushed with N2 (g), sparged with N2, heat-sealed into mylar bags containing Anaeropaks, and stored at -20°C.\n\nEpoxy embedded petrographic thin sections were created using these samples. Subsamples were dried for 24 hours under N2 (g), vacuum embedded in epoxy resin (Struers EpoFix Resin, 1L kit: Part #40200030) following manufacturer's guidelines, and cured under N2 (g) for 24 hours. Each epoxy-embedded sample was pre-cut using a wafering saw then sent to Spectrum Petrographics, Inc. (Washington, USA) for preparation as 30 micron thick, double-polished thin sections mounted on quartz slides using methods to limit sample exposure to water and ambient air. When not in use, thin-sections were stored under N2 (g) to limit oxidation. Thin sections were analyzed for X-ray diffraction at the X-ray Fluorescence Microprobe beamline \"XFM\", National Synchrotron Light Source II (NSLS II), Brookhaven National Laboratory, NY.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nFile_name (unitless)\nSample_name (unitless)\nsample_descrip (Time, unitless)\nHydrotherml_vent_category (unitless)\nLocation (unitless)\nlatitude (Lat_dd, degrees_north)\nlongitude (Lon_dd, degrees_east)\ndepth_f (Depth_mbs, m)\nHdg (degrees)\nDate_collected (unitless)\nTime_collected (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_937020_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_937020_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_937020_v1/index.htmlTable https://www.bco-dmo.org/dataset/937020 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_937020_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_937020_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_937020_v1
