(Collaborative Research: Regulation of plankton and nutrient dynamics by hydrodynamics and profundal filter feeders) Turbulent microstructure profiles were collected near Milwaukee, WI, during 2018 between April 5 \\u2013 April 20, 2018 at a 55m depth site. Microstructure measurements were collected using an RSI MicroCTD (Rockland Scientific International, Inc.), which measures velocity shear, temperature, turbidity, and chlorophyll concentrations. High resolution velocity shear (512 Hz) measurements were used to estimate turbulent kinetic energy dissipation throughout the water column. Microstructure profiles were collected during fair weather conditions on April 5th, 12th, and 20th.\n\ncdm_data_type = Other\nVARIABLES:\nprofile_name (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nDOY_GMT (unitless)\ntime (ISO Date Time UTC, seconds since 1970-01-01T00:00:00Z)\npressure (decibar (dbar))\ntemp (Temperature, degrees Celsius)\nS2 (1/s2)\nturb (FTU)\nchlor (ppb)\ndissipation (Watts per kilogram (W/kg))\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_768011_fgdc.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_768011/index.htmlTable https://www.bco-dmo.org/dataset/768011 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_768011.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_768011&showErrors=false&email= BCO-DMO bcodmo_dataset_768011

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
